Differences between IGF-1 LR3 and IGF-1 DES (mention to PEG-MGF)

[Zakosa]

Hi everyone.


Since I started in the world of enhancing compounds, something that has always caught my attention above the rest are peptides, especially those that promote the increase of growth hormone and its derivatives.

To a greater or lesser extent I have learned a lot about these peptides and their types: MK-677, GHRP, GHRH, HGH Fragment... but no matter how much I research, I lack a lot of updated information (or experiences) about what are supposed to be the most potent: IGF-1 LR3 and IGF-1 DES, in addition to PEG-MGF.

Basically what I come to ask is what you can share whatever you know about these two peptides and their applications, some interesting information to know:

- What are their mechanical differences (at the level of operation)?

- What protocol is usually used?

- For what purpose are they usually used?
(I have seen growing people using IGF-1 LR3 to grow taller, is osteogenesis possible with these compounds?)

- What side effects can occur and with what severity or reversibility?

- How is PEG-MGF related to these IGF-1 variants? Is it really necessary in the first cycle?


I think that's all, any information is valuable for anyone who also has doubts.

This information is valuable, that's why anybody who can answer them properly gets paid to apply it.

Hey Type-IIx lonng time lurker I love your articles! I have seen some concerning reviews for generic IGF-lr3 I tried compounding pharmacy LR3 and it was mind blowing at the time. Do you recommend a certain source for your clients? I see QSC and others stock it

Super bro-science but LR3 might act more systemically whereas DES is more local to injection site. I know of no actual evidence supporting this.

I like LR3 in general. Haven't tried DES but if I did, might consider site-specific injections into lagging muscles or the muscles I'm training that day.

DES injections are thus theoretically bilateral & daily (maybe twice a day), so factor that into your daily injection burden considerations.

I cannot vouch for sources. @janoshik has shared his impressions of LR3 test results. Here ya go: How to make 0.6% acetic acid solution for IGF1 LR3 reconstitution?

I guess its good old trial and error smh, an aussie source, sent me a bunk vial, caused horific water retention on holidays

Do you guys know if IGF-1 DES and/or PEG MGF can be taken subQ in the belly for a systemic effect?

It can and it will, but MGF is a mechanosensitive local autocrine/paracrine IGF-I isoform, if it's to work at all, it'd be locally.

Some people swear by it, saying it’s crazy strong for recovery and hypertrophy, apparently working through the mitogenic and myogenic pathways. Do you think it’s actually worth trying, or is it more hype than results? And any other non-GH peptides you think are solid alternatives? LR3 and DES seem like they don’t do much for humans.

I think they're right. What follows is that it induces muscle repair, i.e., collagen deposition (necrosis). Not muscle remodeling (hypertrophy). It'll grow the muscle's volume, but it doesn't lay down contractile tissue like AAS that stimulate myofibrillar hypertrophy.

If I understand correctly, it will result in useless mass? It won't provide any additional performance (strength or endurance) but will just visually appear as mass?

if it's to work at all, it'd be locally.

Doesn't the pegylated form allow it to work systematically? Since it doesn't degrade as quickly as regular MGF, it should have the time to be absorbed and circulate in your bloodstream, no?

Aka muscle pump, fullness. Aesthetic, not performance.

It probably also appears weird, similar to the necrosis and scar tissue left behind by Synthol use.

That's the theory of PEGylation, unfortunately since MGF (mIGF-IEc, in humans) is a mechanosensitive autocrine/paracrine myokine, its activity in blood/systemic is unknown, but quite likely not beneficial for hypertrophy.

Different even from sarcoplasmic hypertrophy, this is straight up scar tissue.

You make it sound like a bad thing, like it will hinder future hypertrophy.

I think scar tissue is bad, yes. It's what occurs in aging. Can't be good, right? It causes a more brittle muscle prone to tearing, and that probably looks like shit.

Look at the graininess of guys like Dorian Yates, and dare I say, even ovmmds from CLIENT SUCCESSES: BEFORE & AFTER PICTURES

These are instances of training methods that primarily induce myofibrillar hypertrophy.

Sarcoplasmic hypertrophy, guys like cbum, and the modern ilk, mostly.

Then, look at guys like luki4744 or whatever from ProM. He's abused Synthol and PEG-MGF. His muscles look misshapen.
