Will have some EU domestic news for you very soon

 

[anon55]

Hello qsc
Is your HCG recombinant or from bacteria etc or from human sources like Ovitrelle in France wich is frome urine ? Thanks

 

[bighunanballs]

Still no tracking on raws promo payment made 2 weeks ago. Are these actually shipping out domestic? Was this stuff actually on the ground ready to ship? @Qingdao Sigma Chemicals

 

[zailo]

Tout à coup.
Mais si un acheteur commande par exemple uniquement les premiers prêts, il obtient son suivi avant les autres.
Par exemple, pour les gars qui ont commandé les kits de test électroniques uniquement pendant les précommandes, leurs suivis sont déjà disponibles pour la plupart.
Mais c'est rapide, cette semaine je crois qu'ils seront tous prêts.

Les nouveaux lots sont conditionnés en flacons de 15 ml remplis par machine avec une cible de 11 ml environ.
Verre plus épais.
Nouveaux bouchons en caoutchouc.
Pas de flotteurs.

Le lot Primo 100 gris était l'un de ces nouveaux lots.

Nous comptons sur vous pour faire des retours sur les nouveaux lots et s'ils sont améliorés.

Les échantillons seront également envoyés pour des tests.

Nice

I was told last week by Bella that there was no Mast E kits left.

I haven’t update the price list and it’s gonna take me some time to do it

 

[zailo]

Send an email to tracy@sigma email for this

if we proceeded with the purchase and payment of the test promo and then bought other oils during the blackfriday promo but in the continuation of this email, we receive a package from the test promo then after a package with the blackfriday promo is that it?

 

[max187]

All at once.
But if a buyer ordered for example the first ready ones only, he gets his tracking before the rest.
For example the guys who ordered the test e kits only during the preorders their trackings are already available for most.
But it’s quick, this week I believe all of them will be ready.

New batchs are in 15ml vials filled by machine with a 11ml target or so.
Thicker glass.
New rubber stoppers.
No floaters.

Primo 100 grey batch was one of these new batchs.

We count on you to make the feedbacks on the new batchs and if they are improved.

The samples will be sent also for testing.

Can confirm the new vials and caps/stoppers are much improved.
I got the new batch or Primo100 grey tops and I noticed straight away the difference.
Very nice quality.

Hi Tracy @Qingdao Sigma Chemicals i CC'd you on an email earlier regarding my recent black Friday order.
I am having a small issue with Nia your new assistant.
I sent and confirmed payment with her last week but she says she needs to confirm payment with payments department or something?
Also she never sent me the email with the confirmation of order sheet with what I ordered plus my address and phone number etc.
The way Jessica used to do it was very efficient and clear.

Bro im going to try and educate you on the topic because me and the person your talking of have spoken about this and it has come to this (and im not sure if your the manufactorer or middle-man, as as you know purity cost more money to attain).

This is interesting, because "High Molecular Weight" (HMW) proteins can induce side effects, largely through immunogenic reactions.

However, HMWs can either be longer than intended protein chains that aren't removed during the recombinant production process, which would show up in purity tests, or aggregates, which primarily form after reconstitution.

We can see there's been an evolution in the quality of HGH from years ago, when zero dimer was a rarity, for instance. It's important to recognize what was true a decade ago is not necessarily true today.

Since we're seeing 99%+ purity tests on UGL hGH, I'd say the remaining difference between Pharma and UGL is the lack of aggregate formation prevention through the careless choice of excipients (especially PH control), substandard BAC water, excess concentration of reconstituted product, contaminated containers providing aggregate "seeds" that become the nuclei for aggregates, and general poor handling by vendors and end users.

This is unlike the differences between pharma GLPs and UGL GLPs, since pharma is recombinant and UGL is synthesized, regardless of the purity achieved, or the lack of aggregation(though this is also an issue for UGL for the same reasons as above), synthesized proteins appear as more "foreign" to the immune system than recombinant produced proteins and trigger stronger immune responses.

At the end of the day all this points to the fact that if you want to get as close to "pharma" results as you can, use what's in your control to mimic pharma.

Start with the purest HGH / peptide you can source.

Use pharma grade BAC

Reconstitute to the proper minimum dilution ratio.

Filter (even better if done per dose aka "bedside filtration" in medical terms, just before administration, but this can be a pain in the ass, though there are ways to make it more practical).

Transfer to a container that's been certified particulate free by an FDA facility (these are cheap).

Protect from heat, impact, and light by spending the extra dime on amber glass(thanks @Clover 0080) .

Try to use lower dose vials to minimize the time your peptide/HGH is in reconstituted form.

@Qingdao Sigma Chemicals What color are the caps on the Test-C 250mg vials from the Test Apocalypse Promo supposed to be? I was expecting purple based upon the link to the Jano on the price list, but I received blue cap vials which the price list shows as being Test-E.

I'd be curious on your opinion if a person nonchalantly used UGL HGH and reconstituted at a high concentration potentially spiking immune response, would this eventually lower over time if you took steps to filter aggregates and diluted your HGH concentration. Curious if "the damage is already done" do you just need to take a break then restart it again after X amount of time with better protocols hopefully lowering the potential for immune response.

Curious if "the damage is already done" do you just need to take a break then restart it again after X amount of time with better protocols hopefully lowering the potential for immune response.

Obviously we're always going to be hampered by the fact we, as in UGL users, are not getting antibodies checked, or closely monitoring outcome like pharma does during clinical trials, and in the case of GH treatment, even the way "normal" patients are monitored for antibody development and loss of efficacy.

What we do know is that

1) In those on pharma GH treatment antibodies can and have risen high enough to lessen effectiveness of the drug and in some cases worsen the original problem of some patients. A very small percentage have had to be taken off HGH because of this,

2) Despite not measuring its impact, every factor known to worsen immunogenicity is present in UGL Hgh, and the methods by which it's reconstituted, handled, and used. So the above problem is going to develop at some higher. but unknown rate.

3. To your specific question, the concept of "re-exposure" after breaks in peptide/protein drug treatment is recognized as increasing the risk of immunogenicity problems vs subjects who are "naive". "Continuous exposure" often results in less of an immune reaction than stopping and restarting. I can't find any studies about treatment "vacations" with GH specifically, but we do know that on pharma GH, most often immunogenicity peaks, and levels off, allowing for years of treatment without rising to a level where it impacts the effectiveness of the drug. However, pharma GH is all about keeping immunogenicity low. If it were higher, this may not be the case, and effectiveness could progressively drop, and sides worsen over time. This is major reason for the failure of many peptide/protein drugs in development, and even the case with numerous FDA approved protein therapeutics, including some GLPs, but the affected group is small enough the FDA allows the drugs to be used with additional monitoring for immunogenicity.

Whether and how long of a break it takes to "reset" your immune system to a HGH "naive" state is unknown.

A good analogy for all this are vaccines. They induce a desired kind of "immunogenicity" by the same processes we want to avoid with peptides. Some vaccines need to be renewed often, because the immune system "forgets", and others are good for a lifetime, because the immune system "never forgets" how to rid itself of that particular protein.

So the bottom line, do what you can to minimize the risk. I wouldn't take an otherwise undesired break to try and "reset" since we don't know if or how long that would take to work, and it could actually worsen things. With other protein therapeutics, repeated breaks amplify this immunogenic effect vs a single break. That's why some vaccines are given as a series with breaks in between shots, to maximize the immune system's "lesson" in how to quickly remove a protein invader.

When it comes to HGH concentration, the highest I've found that does not produce problematic levels of immunogenicity (for a pharma formulation that has anti-aggregation excipients) is .05ml per iu, ie. 5iu 2.5ml (or 25units) allowing for a much more concentrated solution than a lot of other peptides, but of course, we're not dealing with pharma's ideal formulation and conditions, so going more dilute than that minimum would be a good idea. Most pharma manufacturers of HGH(aside from multi-dose pens) seem to shoot for an injection volume range of .3ml to .8ml for every dose, regardless of ius.

It's not excipients brother, it's the API itself.

Only the last few years Chinese have seemed to make a leap, before was harder to find generic gh as ecoli tanks etc was expensive.

I don't know where you find 99% purity generic id be interested to see it, but there is a table somewhere on this forum, quoting lobster, qingdao and others all in the realm of 95-97%. For them to get to 99% cost money, lose of product and overall decrease in total output. They don't want to do that, because 'bloods' are good, but people that have been around know what were talking about. That's why you rarely hear of pros tout a generic. Because that's one thing the Chinese are yet to master. Maybe in 2-5 years there generic will get there, but as of now alot more 'jano' reports and posts like this.

I just read a few studies on children taking double that for over a year.
Here is a two of them

Careful with the weight adjusted dosing in kids vs adults.

Good comments by T2X are applicable.

You guys have to be careful interpreting data (clinical trials, research abstracts or full text). Physiological rationales for dosing depends on the subject population. For example, in adults rhGH dosing is logically based on body mass (m^2); then at some point the WHO put out an advisory that dramatically curtailed doses based on tolerability. In children, doses are often like 0.1IU/kg 3x weekly (though an advisory was put out to get away from using IU in GH research, likely because it was readily comprehensible yet dangerous for this very reason for the average guy). Anecdote: A guy that posts here says/believes strongly that he developed congestive heart failure because he used doses from a study in children based on mg/kg. DO NOT DO THIS.

Look at the long term studies and reasonably safe dosing of oxandrolone and stanzolol in adults.

Yes I am posting in this thread against what I said yesterday since this is important topic. Ideally I'd move it somewhere else but so be it.

See research paper as well:

Anabolic steroid use increases heart attack risk and causes liver damage

Anabolic steroid use causes decreased levels of HDL or "good" cholesterol, increased levels of LDL or "bad" cholesterol, and serious liver toxicity within 12 weeks, according to a study that measured the effects of anabolic steroids on men with HIV wasting disease.

What I'm asking is this. How are HMW proteins present in the API represented in purity tests like the ones Jano performs. Are they recognized as impurities, reducing purity, or are they slipping through. Because unless I'm mistaken, haven't we seen 99% HGH results from his lab?

Excipients are certainly a factor in aggregate formation control, even the material used for the containers of HGH is a carefully controlled factor, but that's a separate issue, post manufacture where there's some hope of improvement. Can't do much about oversized proteins in the API.

I don't know you'd have to ask him; but based on my understanding anything that is not part of the final purity I would consider an 'impurity".
