I copied and pasted this write up.

I wanted to see what everyone thought of it.

I was thinking of using cjc in my research log that I have started on this forum. I'm getting my BF tested tomorrow to get my stats in order and will be taking more pictures.

I wanted to see what everyone thinks / knows about this product so as to be able to post my results that others can refer to when doing their own research.

This write up was post late 2009 (I believe).

Its kinda long but interesting.



Ive been using Lr3IGF-1 since I was 18 years old. When I first used it I was using the australian company who created it, GroPep's stuff before they caught on that 99% of their sales were to bodybuilders.

Ive also used GenSci's Igtropin (overpriced bull****), generic chinese LR3IGF-1 (blue top), and LR3IGF-1 from a half dozen various suppliers.

Its alright. But not in anyway shape or form anything like what your saying.

First, LR3IGF-1 nor IGF-1 gives DICKALL for gains. Seriously. Anyone is DAMN LUCKY if they gain just 5lbs in a 4 week cycle of LR3IGF-1. I can gain 30lbs in 4 weeks with Dianabol at 1/5th the cost of LR3IGF-1.

Lr3IGF-1 gives OKAY pumps. NOTHING like what your saying, nothing. Try OXANDROLONE if you want to feel a REAL PUMP, will make Lr3IGF-1 pumps look like a day at the beach...... *reminiscing time - wavey flashback distortions* Years ago a new canadian UG lab released an Oxandrolone product that was supposed to be 25mg/capsule of Oxandrolone. However to stir up good feedback with their first batch, they doubled up the dosage, to 50mg per capsule yet said it was just 25mg. So everyone, including me, was taking 2 capsules thinking we was using 50mg, but in reality using 100mg (a whopping dose of Oxandrolone). Just standing there, not lifting any weights or anything, gave such an INTENSE pump in the lower back it was painful as ****ing hell, this is without any exercise, just simply standing there. If I lifted a cup of coffee my arms would get pumped, if I lifted a weight, theyd get so pumped I was literally afraid the muscle was going to rip off its ligaments from the pump alone.

Even off 50mg of Oxandrolone, I get pretty bad lower back pain from the lower back PUMP, this is without exercise. Alls I do is take 50mg of Oxandrolone, and walk up 15 steps, and by the top my lower back is pumped up so tightly it actually hurts.

Lr3IGF-1 has never come 1/10th as close. I get better pumps from many other AAS, LR3IGF-1 pumps are 6/10 on my pump scale. Oxandrolone is 10/10.


Lr3IGF-1 and HGH do dickall for mass gains, dick-****ing-all. What they do do and why people DO use them is because they allow body composition changes. Meaning you can gain 2lbs in a 4 week Lr3IGF-1 cycle, yet at the same time, you lost 3lbs of fat as well. Not many steroids can make you LOSE fat and gain muscle simultaneously. THATS why we use LR3IGF-1 and HGH, because they allow that. But neither the fat loss nor the muscle gain will be as dramatic as what you can achieve with either steroids or special lipolytic agents. Instead you get a balance between the two happening simultaneously, which is beneficial. This is why people ADD steroids and/or lipolytic agents ontop of the Lr3IGF-1 or HGH, to further expand its effects in either or both directions.



Now that-that totally exaggerated bull**** has been cleared out. Onto the topic at hand.

HGH fragment = complete scam, useless ****, utterly, useless, dont ever waste a penny, horrible failure to deliver ANYTHING

PEG-MGF = totally nutsuckingly ****ty, another utter failure to deliver anything, local, systemic, either way, it blows chunks, simply not worth the money, too little result for too much cash, save ur cash, pegylation sucks compared to bioconjugation, and MGF sucks period


CJC-1295 = GOD!! ****ing GOD! Ive been using this almost non-stop since the day I first tried it. This **** is GOD. The single most beautifully developed peptide ever to come across the BBing scene. In-****ing-credible. This is seriously a FLAWLESSLY designed pharmacologic agent. The things ConjuChem did for developing this peptide is phenomenal. Ive never been more proud to be Canadian (ConjuChem is Montreal based company!). Even more incredible, this product provides the perfect foundation for enhancing it to a level greater than anything thats ever existed for the bodybuilding scene before. Something I discovered that ive been experimenting with for the past little while that no one else seems to have realized, and I need to break the silence on it and open up the can of worms.

Im telling you, CJC-1295 is PEPTIDE PERFECTION. There will never, ever, be any greater peptide than this peptide to ever hit the BBing scene, ever, thats a guarantee. It cannot get any better than this, it really cannot its the pinnacle. Lr3IGF-1 is OBSOLETE, HGH is OBSOLETE, SERMORELIN? HEXARELIN? GHRELIN? GHRP-2? GHRP-6? ALL OBSOLETE, LAUGHABLE by comparison. Its PERFECT dude.


First these dudes (ConjuChem) realized that natural pulsatile release patterns are more effective and less likely to promote acromegalic deformations verse exogenously supplier recombinant HGH. So they chose GHRH to base their masterpiece off of, and thats exactly what it is a fawkin masterpiece.

Next, these sons of bitches analyzed all the proteases in the body that cleave various amino acids from the GHRH peptide and therefore degrade and deactivate it after approximately 7 minutes. They then chose to remove all the exact specific amino acids that undergo proteolytic cleavage in the GHRH peptide string and replace them with amino acids that cannot be cleaved by the bodies proteases. GENIUS. It makes it virtually immortal. They then modify it to undergo bioconjugation and bind to albumin, one of the most abundant compounds in the body, to further enhance its duration and prevent its clearance from the body. Creating a monstrously mutant masterpiece.


GHRH lasts around 7 minutes because of proteolytic cleavage. CJC-1295, a GHRH-derivative, lasts between 8-10 days from a SINGLE injection. Because its a GHS (Growth Hormone Secretagogue), it maintains the natural pulsatile release patterns rather than injecting exogenous recombinant growth hormone. By maintaing the patterns it allows the bodies other systems to work in harmony with it, such as GHBP's (Growth Hormone Binding Proteins), GHBP's control/prevent side effects such as acromegaly by dictating the actions of GH, like IGFBP's dictate the actions of IGF-1. When you inject exogenous HGH, the body isnt "prepared" for its existence, therefore it does not provide sufficien GHBP's to control its actions, etc, and therefore you get random abnormal growth of organs and such because theres insufficient GHBP's to deliver the HGH to where its NEEDED, and instead it just binds to whatever receptors it comes across at random. This leads to acromegalic side effects more readily.


CJC-1295 has many more things going for it as well aside from flawless pharmacokinetics. Its LEGAL. When you buy it you KNOW what your getting, not like HGH which is sometimes HCG counterfeits. Your not going to get scammed trying to buy it like what happens countless times buying HGH. Its much cheaper to use than HGH. From the resellers you pay about $100/2mg, from the China supplier (who supplies the resellers too), its just $40/2mg when buying 10mg. Even cheaper if you buy more than 10mg.



So how does CJC-1295 and GHRH work?

They are GHS, Growth Hormone Secretagogues. They work by binding to the GHSR (Growth Hormone Secretagogue Receptor), where they signal the pituitary to release HGH. Once a 'surge' of HGH is released, the negative feedback mechanism kicks in and causes a rise in Somatostatin. Somatostatin is an inhibitor of HGH release. Once somatostatin levels decline, more HGH can be released, but wont be released immediately in the natural endocrine system. However because CJC-1295 lasts 8-10 days straight and thus signals the GHSR 24 hours a day for 8-10 days straight, the moment somatostatin levels decline after a surge, the CJC-1295 will immediately signal another surge. This occurs throughout the entire day and while you sleep.

HGH lasts only like 15-20 or so minutes in the body before its deactivated by proteases and whatnot. Because of CJC-1295's constant GHSR agonist activity, you therefore get MANY surges of HGH per day. Rather than just a couple under normal endocrine activity with GHRH. And rather than just 1 additional surge you get when injecting exogenous recombinant HGH.

This is why HGH takes sooo long to show results. Because everyday you inject it, your only getting 15-20 minutes of supraphysiological HGH exposure. Therefore if HGH lasted lets say 10 minutes, after 7 days of injecting, thats only 70 minutes of total exposure to supraphysiological HGH youve had. The body cant do much growing in just 70 minutes. Hence why it takes months of HGH use to accumulate significant enough time under supraphysiological levels to elicit a noticeable effect. CJC-1295 on the otherhand gives MANY surges per day, therefore its like injecting HGH 10 or 20 times or even more in a single day. The results come FAR faster and are greater.

CJC-1295 gives me the most INSANELY vivid and long lasting dreams. It also gives me numb extremeties and all the other effects of supraphysiological HGH levels. GREAT STUFF.


I will expand into my "UBER-PITUITARY" optimizing method tommorow when I explain why CJC-1295 is the PERFECT foundation for doing something simply INCREDIBLE.


In short: CJC-1295 is the greatest peptide ever made available. It makes ALL other peptides useless. L3IGF-1 is useless. HGH is useless. Its all useless now. CJC-1295 has taken over. Its the only thing worth buying.

HGH doesnt have many side effects not sure where you get that from.

In the short term, GH side effects are all that from supraphysiological levels of growth hormone. Meaning, if your NOT experiencing these side effects, it means your NOT using a large enough dosage of HGH (or CJC-1295 or anyother somatotropic-modulator) to bring your GH levels beyond their natural levels thus causing the side effects of supraphysiological levels. So you WANT to exeperience these short-term below side effects;

- Vivid dreams (long, vivid dreams you'll rememebver well)
- Numbing in the extremeties (fingers/hands should go numbish)
- Aching joints (its not a painful ache really, its a very very very dull ache feeling in the joints - like growing pains)
- Mild hypoglycemia if on a low-carb diet (eating carbs is a must when using HGH/IGF-1 otherwise you'll notice mild hypoglycemia as in you'll feel faint, weak, fatigued, lightheaded, dizzy, you wont go comatose but it does take you down a notch)

You WANT to experience the above, that lets you know your using a high enough dosage. If you dont experience those, you must increase your dosage, as it means your only using a large enough dosage to replace your natural levels, which defeats the entire purpose of using GH/GH-mimetics. None of these side effects have any long-term reprecussions.

Long-term side effects are those below. However these take YEARS to develop, you must use HGH and friends for months or years straight, or very frequently, before you will have a chance of developing these to a notiecable level, the average GH user wont ever worry about these to any significant degree unless theyre spending $20,000+ dollars on HGH;

- Excess organ enlargening
- Excess circumferential skeletal growth (acromegalic facial distortions such as enlarged forehead and thickened brow-bone creating neanderthal look)
- Increased hand and foot size



Whereas anabolic steroids can have side effects that appear MUCH MUCH faster (weeks or even days for some), and can be pretty nasty and some long-term;

- Acne or BACNE (rocky mountain back which virtually never goes away)
- Extreme body hair growth (I can vouch for this disgusting side effect, I HATE IT, 24/7 battle against the body hair)
- Liver damage
- Cholesterol problems
- Accelerated male pattern baldness
- Increased blood pressure
- Infertility/testicular problems
- Breast development (gyno)



I think GH/IGF-1 have much less side effects than AAS. The short-term sides of GH are indicators of effectiveness and dont ever stay after you discontinue use. The long-term sides take a long long time to develop, ive been using for years and never encountered any noticeable changes in facial bone or anything. Alls ive noticed is mild increase in hand and feet size and tiny increase in wrist circumference. I feel way more comfortable, side effect wise, using HGH than steroids thats for sure. Im sure MOST do.

I mean with AAS you NEED to use lots of ancillary components to prevent the side effects, such as aromatase inhibitors, alpha-reductase inhibitors, blood pressure meds (for some users), liver protectorants, special acne meds, post-cycle therapy protocols, etc.

But you dont need nor does anyone use anything to combat GH/IGF-1 side effects because theyre virtually non-existent in the long-term. And the short-term effects have no relavancy to anything other than to identify the legitimacy of the stuff your using and the effectiveness of your dosage.


Now onto enhancing CJC-1295 to blow it into the next universe of effects.

CJC-1295 is the perfect foundation for doing this. Because it lasts 24 hours a day for 8-10 days straight. Whereas GHRH, which does the same signalling of the GHSR, only lasts 7 minutes.


First its important to understand how GH surges work. Pay especial attention to Somatostatin.

When a secretagogue of GH, such as GHRH, Ghrelin, Hexarelin, or CJC-1295, signals the GHSR it causes the pituitary to release HGH, IF, Somatostatin levels are low enough to allow it. Once a surge of GH is released, Somatostatin levels will rise up again, thus even if something is binding to the GHSR, it CANNOT signal the release of GH because Somatostatin levels are too high.

Somatostatin is what controls the negative feedback mechanisms of GH release in the pituitary. After a surge of GH is released from a secretagogue wether natural or man-made, Somatostatin levels will rise, preventing further GH release until the GH levels decrease, at which point the ultra-short feedback mechanisms of the hypothalamus-pituitary-axis (HPA) kick in and cause Somatostatin levels to decrease.

The moment somatostatin levels decrease sufficiently, more GH can be released. However under natural conditions, there wont be sufficient GHRH remaining at the GHSR to cause more GH release once Somatostatin levels decrease. Because GHRH is also released in surges, and only lasts 7 minutes upon its circulating release.

However because CJC-1295 lasts 24 hours a day for 8-10 days, its ALWAYS at the GHSR, so the moment somatostatin levels decrease enough, another surge of GH will happen because CJC-1295 is there binding to the GHSR's. Therefore under naturakl endocrine system, you'd get lets say 5 surges of GH a day. Whereas with CJC-1295, youd get lets say 15 surges of GH a day.

So whats the obvious limiters of GH release?? Well first, is the duration of GHRH or whatever GHS is signaling the release. This has been overcome with CJC-1295.

Whats the second limiter? Somatostatin. Somatostatin is an inhibitor of GH release. Not so easy to fix??? WRONG! This is where I come in.


Amazingly, no one that ive seen has realized this. That is, if you could inhibit Somatostatin levels while using CJC-1295, you would allow the CJC-1295 to signal an ENDLESS surge of GH (so long as the body was producing sufficient peptide, which means you need a high protein diet since peptides are made from amino acids in protein). Yes, thats not a typo, an ENDLESS surge of GH. The equivalent of strapping an IV bag of HGH to your back and walking around all-day with a drip of GH into you. The difference between the "surge" system and that would be night and day. Im not saying its the healthiest or safest thing to do, but it is so far beyond the natural endocrine function it will lead to results never before experienced or even imagined with HGH of any kind or any way previously available. I can vouch for this as ive been experimenting with this recently.


There is a class of compounds called Acetylcholineesterase inhibitors, that inihibit acetylcholineesterase, which is responsible for deactivating acetylcholine in the brain. Guess what? Acetylcholine is a very effective inhibitor of Somatostatin. Therefore Acetylcholineesterase inhibitors are indirect somatostatin inihibitors, working by increasing acetylcholine levels which then inhibit somatostatin levels.

Does this really work? YES, its been clinically proven in numerous studies with stunning results. In the studies they used GHRH + Acetylcholineesterase inhibitor Pyrostigmine at a dosage of 120mg. Remember GHRH only lasts 7 minutes, so they only get a single surge of GH from using it. What the study found is that orally administering Pyrostigmine, an acetylcholineesterase inhibitor, and then injecting GHRH vs. the placebo/control group resulted in a dramatically larger amount of GH released in response to the same dosage of GHRH. This is because somatostatin levels were dramatically lowered, and allowed an even larger amount of GH to be released in response to GHRH.

Had the study used CJC-1295 they wouldve had a far greater result. Not only would more GH be released per surge, but they wouldve had an endless or damn near endless surge of GH release, rather than the normal "Pulsatile" release system which is controlled by:

A) The short duration of GHRH and other endogenous secretagogues (overcome with CJC-1295)

B) The GH-inhibitory action of Somatostatin (overcome with acetylcholineesterase inhibitors)



Acetylcholineesterase inhibitors are taken orally, they are legal and readily available for purchase as they are extracted from natural plant sources. They are CHEAP, costing just a dollar or less per day to use in conjunction with CJC-1295. By taking them you can use a lower CJC-1295 dosage and still get much greater results. It totally changes the pituitary system into what I must call the uber-pituitary.

Normally the pituitary functions like this;
1) Endogenous GH secretagogue such as GHRH or Ghrelin, signals pituitary to release HGH, the amount of GH released is controlled by somatostatin and GHRH quantity.
2) Pituitary releases HGH creating a 'surge', immediately after, somatostatin levels rise thus making the pituitary unresponsive to GHRH or other secretagogues, GHRH remaining becomes deactivated due to proteocyltic cleavage.
3) After the HGH released has become deacticated by the body, Somatostatin levels begin to decrease again, and once more endogenous secretagogues arrive, another surge will occur and repeat process.


The pituitary function using CJC-1295 + a somatostatin inhibitor (in this case acetylcholineesterase inhibitors), functions like this:
1) Exogenously supplied GH secretagogue CJC-1295 signals pituitary to release HGH, the amount of GH released is GREATER than without acetylcholineesterase inhibitor due to suppression of somatostatin.
2) Pituitary releases HGH creating a surge, however, somatostatin levels fail to rise after the release, therefore the pituitary remains responsive to secretagogues to signal more release of HGH, and the CJC-1295 fails to degrade due to its design thus lasting 24 hours a day for 8-10 days from an injection.
3) After the HGH is released, ANOTHER surge is immediatley signalled by the still active CJC-1295, and then another surge, and another, and another, and another, and another, and in the time span that 1 natural surge wouldve happened and another would be ready to go, probably 20x as many surges have already occured.



So for just 50 extra cents a day and the consumption of an oral pill of a legal, readily available compound, you can ABSURDLY modify the pituitary response to CJC-1295 by suppressing Somatostatin. YOUVE BEEN WARNED, this is INSANELY potent, beyond the design of humanity. BE CAREFUL!


Theres 3 common acetylcholineesterase inhibitors, they are;

Pyrostigmine (120mg/ed)
Galantamine (8-16mg/ed)
Huperzine A (50-150mcg/ed)


NOTICE, Huperzine A dosage is in the MICROgrams NOT MILLIgrams. If you took 50mg of Huperzine A you would DIE. I use Huperzine A myself for this. But you can use any of the above, perhaps pyrostigmines better because thats what was proven effective in the clinical studies at that specific dosage. But all three of the above are acetylcholineesterase inhibiors and will thuis have the same inhibitory impact on somatostatin.


This is how, for just an extra 50 cents to a dollar a day, you can turn CJC-1295 into the physiological equivalent of strapping an IV bag of HGH to your back and having a 24 hour drip. As you can imagine this is ABSURDLY POWERFUL and needs great respect and caution when you first begin experimenting. Start with a low CJC-1295 dosage and a low acetylcholineesterase inhibitor dosage, and work from there based on your experiences.


EVERYONE should do this. It gives you FAAAAAAAAAAR more bang for your buck from the CJC-1295, and costs just cents per day to do ontop of CJC-1295 use. Its supported fully by clinical studies, just search for the pyrostigmine/GHRH study.
 
Nearly took me all morning to read this! Sounds like this guy was getting blown by the CJC-1295 creators when he wrote this. Actually sounds like a more intelligent version of BillyB, haha:D

I've always wondered about CJC 1295. I haven't heard the rave reviews that this guy is expressing. However, this could be because people do not know how to properly use the drug. I would be very skeptical if someone told me that CJC works better than HGH and IGF1 Lr3.

Anyone else use this drug recently with any results at all?

You read my mind!
I was like REALLY!? Its that good?

He is like "you can turn CJC-1295 into the physiological equivalent of strapping an IV bag of HGH to your back and having a 24 hour drip. As you can imagine this is ABSURDLY POWERFUL and needs great respect and caution when you first begin experimenting." WTH!? Is this true?

The cost of HGH vs CJC for 5 weeks is about a $50 dollar difference (50 more for HGH for 5 weeks). But I haven't heard anybody push this stuff like this guy is.

He sounds like he knows what he is talking about. He got me kinda excited. I'm wishin and hoping this guy is right. Because I will be ALL OVER THIS! I just need some kind of confirmation.

the whole article just sounds like a damn commercial for the shit. I don't buy it. ESPECIALLY if you only save 10 bucks/week vs HGH. What a joke.

Especially since it's much easier to obtain CJC...IMO. I need to do some more research on this. It's got me interested, but there's no way it's a miracle drug like this guy is saying it is. It can't be or we'd be hearing a lot more about it.

exactly...
 
exactly...

I'm not saying that I'm not dumb enough to give it a shot though:D Fuck it...CJC-1295, HGH, IGF-1 Lr3, GHRP-2, GHRP-6 and MGF every day....sounds good to me. Throw in some Melanotan II and viagra and I'll be ready to take over the world!
 
the whole article just sounds like a damn commercial for the shit. I don't buy it. ESPECIALLY if you only save 10 bucks/week vs HGH. What a joke.

That is true. Its only $10 a week but what got me was that hgh only last like 7 min in your system vs cjc's 8-10 half life.

I do think that your on to something Stretch it does sound like a pitch, but dang this is a really good pitch if it is.

Also I have never heard anyone ragging on IGF-1 and the few other peptides. It kinda remindes me of how I felt about most supps on the market vs creatine (when I first learned about it in the mid 90's). Most were just garbage compared to it. So I just got to know

This link had a lot of info but this stuff is WAY OVER MY HEAD at this point. Just too much.
Dat's - CJC-1295 & GHRP-6 (Basic Guides) - Professional Muscle
 
Just google "GH Bleed"....much easier to find that way.

The company that I get my peptides from sells cjc 1293. They also call it modified GRF 1-29 or "non DAC" cjc-1295. Without the DAC (drug affinity complex) the half life becomes much shorter, but still long enough to take advantage of. CJC-1295 has a half life that lasts several days, that's why it's called "GH Bleed." GH is on a constant drip like an IV and IGF-1 levels become eleveated and stay elevated for a long period of time. Sounds good in theory, right? Until you consider the fact the prolonged elevated IGF-1 levels are not healthy and have been linked to various cancers. The modified version in 1293 is supposed to cut the half life down to about 30 minutes. So, you'd need a few injections per day to make it work. It seems that this compund works synergistically with GHRP-2 or GHRP-6.

Here is a more intersting article based on studies and evidence that may make more sense concerning this subject... (it doesn't really take that long to read, I promise:rolleyes:)


CJC-1293 Modified GRF (1-29)


In the healthy human body, large amounts of growth hormone are stored in the pituitary. The cells within the pituitary release growth hormone in response to signaling by GHRH (Growth Hormone Releasing Hormone), Ghrelin (of which GHRPs - Growth Hormone Releasing Peptides - are mimetics), and are inhibited from releasing these stores by Somatostatin. GHRH and Ghrelin act on different populations of somatotropes (GH releasing cells). GHRP/Ghrelin increases the number of somatotropes releasing GH but not the amount released by each cell; GHRH affects both the number of secreting cells and - more so - the amount they each secrete. [1] GHRH and Ghrelin are released in specific patterns that vary depending on event and environment: post-exercise, in response to slow wave sleep, in certain stages of life and physical development, and so on.



Most people (even the diseased) continue to possess the ability to make GH in the pituitary. The problem is in the signalling of the pituitary to release it and make more. Even most people with diseases that affect growth hormone secretion retain the ability to continue to make GH in their pituitaries. The disease states and symptoms result, most typically, in altered (dysfunctional) GH release signaling and this also affects the ability of the pituitary to continue to make more GH. [2]



Endogenous-type GHRH, which has a forty-four amino acid long chain (and a specific shape - thus making it a peptide as well as a hormone), has been marketed for the longest as Sermorelin in comparison to the other GHRH-type peptides. However, Sermorelin has been demonstrated to be degraded rapidly in the body and is cost-inefficient. But because most patients in need of GH therapy do retain the ability to produce and secrete their own GH, treatment with a GHRH-type analog remained hypothetically preferable to exogenous GH treatment. GH itself when administered exogenously results not only in "unnatural" release patterns, it results universally in down regulation of endogenous GH production - as do many hormones when applied exogenously. [2]



Sermorelin's limitations naturally resulted in a variety of formulations of GHRH analogs for therapeutic usage. CJC-1295, discussed in another article, is a GHRH analogue with attached MPA (aka DAC), binds to albumin in the bloodstream and circulates for a week or longer. Modified GRF 1-29, which is also called D-Ala2-GHRH-(1-29), [Nle27]-hGHRH(1-29)-NH2, GHRH (1-29)NH2, or ModGRF1-29, is the bioactive portion of GHRH(1-44) with fifteen amino acids subtracted and four amino acids replaced at the weakest points in the peptide structure.



Soule et al write that "D-Ala2 substitution contributes to the enhancement of biological activity by reducing metabolic clearance." [3] In a comparison study with synthetic exogenous GH for treating prepubertal GH deficiency, Lanes and Carillo concluded that "GHRH (1-29) at the dose and schedule used is generally effective in the treatment of GH deficiency." [4]



Campbell et al explain both GHRH(1-44)'s shortcomings in treatment as well as advantages offered by Modified GRF (1-29) and specific structural differences:



Native human GRF(1-44)-NH2(hGRF44) is subject to biological inactivation by both enzymatic and chemical routes. In plasma, hGRF44 is rapidly degraded via dipeptidylpeptidase IV (DPP-IV) cleavage between residues Ala2 and Asp3. The hGRF44 is also subject to chemical rearrangement (Asn8-->Asp8, beta-Asp8 via aminosuccinimide formation) and oxidation [Met27-->Met(O)27] in aqueous environments, greatly reducing its bioactivity. It is therefore advantageous to develop long-acting GRF analogues using specific amino acid replacements at the amino-terminus (to prevent enzymatic degradation): residue 8 (to reduce isomerization) and residue 27 (to prevent oxidation). Inclusion of Ala15 substitution (for Gly15), previously demonstrated to enhance receptor binding affinity, would be predicted to improve GRF analogue potency. Substitution of [His1,Val2]-(from the mouse GRF sequence) for [Tyr1,Ala2]-(human sequence) in [Ala15,Leu27]hGRF(1-32)-OH analogues completely inhibited (24-h incubation) DPP-IV cleavage and greatly increased plasma stability in vitro. Additional substitution of Thr8 (mouse GRF sequence), Ser8 (rat GRF sequence), or Gln8 (not naturally occurring) for Asn8 (human GRF sequence) resulted in analogues with enhanced aqueous stability in vitro (i.e., decreased rate of isomerization). These three highly stable and enzymatically resistant hGRF(1-32)-OH analogues, containing His1, Val2, Thr/Gln8, Ala15, and Leu27 replacements, were then bioassay for growth hormone (GH)-releasing activity in vitro (rat pituitary cell culture) and in vivo (SC injection into pigs). Enhanced bioactivity was observed with all three hGRF(1-32)-OH analogues. In vitro, these analogues were approximately threefold more potent than hGRF44, whereas in vivo they were eleven- to thirteen fold more potent.[5]



Just as GHRH and Ghrelin work in conjunction through different means for maximal GH release within the body, exogenous GHRH such as Modified GRF (1-29) results in a synergistic effect when used with a Ghrelin mimetic, such as the hexapeptide known as GHRP-6. [6] Pandya et al also conclude that "GHRH is necessary for most of the GH response to GHRP-6 in humans." [6] Massoud et al conclude that "Hexarelin and GHRH-(1-29)-NH2 are synergistic" [7] (Ed note: Hexarelin is another Ghrelin mimetic).





Sawada writes that "findings suggest that the KP-102-induced GH secretion largely depends on GRF and the secretagogue potentiates the GRF effect by antagonizing the SS action at the level of somatotropes. It is concluded that KP-102 alone or in combination with GRF provides a means of stimulating GH secretion in the face of elevated inhibitory tone mediated by SS." [8] (Ed note: KP-102 is the Ghrelin mimetic GHRP-2)



An abstract of a review by Hamilton touches on the main advantage of GRF(1-29) over, for example, CJC-1295 or synthetic GH:



...growth hormone secretion occurs in a rhythmic pattern regulated by intricate interactions between two neurohormones: growth hormone-releasing hormone (GHRH) and somatotropin release-inhibiting factor (SRIF).[...] research also indicates that there are sexual differences in the pattern of growth hormone release and that growth hormone regulates its own secretion by means of a negative feedback system. [9]



By mimicking natural release patterns with properly dosed and timed GHRPs (Ghrelin mimetics) and GHRH-analogues, negative feedback and undesirable side effects that are typically seen in synthetic GH therapy or even with past forms of GHRH administration (such as constant low-dose administration via pump) can be avoided.



For achieving ends other than restoring natural GH release in diseased patients, optimized rhythmic or pulsatile dosing of GHRH with or without a GHRP may be useful, as Vittone et al write about their findings on GHRH applied to healthy elderly men:



...data suggest that single nightly doses of GHRH are less effective than multiple daily doses of GHRH in eliciting GH- and/or IGF-I-mediated effects. GHRH treatment may increase muscle strength, and it alters baseline relationships between muscle strength and muscle bioenergetics in a manner consistent with a reduced need for anaerobic metabolism during exercise. Thus, an optimized regimen of GHRH administration might attenuate some of the effects of aging on skeletal muscle function in older persons.[10]

Good article; do you think it makes sense to cycle CJC-1293 and GHRH-6 with GH. If the constant use of GH creates a desensitization or threshold effect, wouldn't it be logical to do GHRH instead of GH pre-bedtime (if that' when you dose?

Secondly at what times during the day do you recommend doing CJC-1293 and GRHG-6?

At one point the article states "...data suggest that single nightly doses of GHRH are less effective than multiple daily doses of GHRH in eliciting GH- and/or IGF-I-mediated effects."

So, it sounds like you could do 2 or preferably 3 daily doses of 1293 and GHRP-6 to achieve desired results. Whether these doses should be evenly spaced throughout the day or be structured around workouts is beyond my realm of understanding at the moment. I have heard that doses of 100mcg of each per day are sufficient for measurable results.

This is a great start guys, but personally I'll have to do a little more research on the 1293/GHRP-6 combo before I recommend it to anyone or take it myself.
 
GHRP 6 or 2 work fine alone to temporarily elevate one's own growth hormone & related physiological activity. Add CJC-1295 & the wavelength of effect is broadened, meaning the effective time of higher GH activity is prolonged. However, more recently DatBTrue has been promoting GHRF (1-29) over CJC-1295 (though both need the GHRP base to be effective), as the way to spend more time elevated natural growth hormone levels.

Since I'm not using GH for actual muscle growth but for leaning & general healing (not to mention anti-aging), I don't need expensive exogenous GH. Peptides have been working fine and are much cheaper. Call me a sucker, but I've just received my packet of GHRF (1-29), trusting it will enhance the GHRP-2 I'm already on. Plus GHRF (1-29) is slightly cheaper than CJC-1295).

Hope I notice it with all the Tren/EQ/Test I'm currently on.:rolleyes:
