GRF-129 and Sermolin are the same thing, mod GRF 129 is
modified(tetrasubstitued) so not
exactly the same thing. I wouldn't use either one solo, would always use a GHRP of some sort (Ipa) alongside. I look at it as the GHRH's clear any impediments to a pulse (feedback loop type stuff) and the GHRP's cause or amplify said pulse.
GHRH- Growth Hormone Releasing Hormone
GHRP- Growth Hormone Releasing Peptide
Sorry I didn't have time for a more comprehensive answer in first post but I did know what you were after.
Somethings to be said before I answer - I haven't really used
a ton of it, the majority of my thoughts about peptides come from opinions formed from info on the old DatBtrue site. I find peptides to be harder to understand and discuss than AAS and that site had some very high end content that was well beyond what most anyone without some serious education could hope to understand.
Unfortunately giving personal feedback on this stuff swings damn near %100 to the anecdotal side, other than sometimes getting a slight flush post dosing it doesnt exactly jump up in your face and yell "I'm here, look what I'm doing". For example a heavy dose of your fav PreWO will be easy to feel (in positive and negative ways) but a small bump in GH output is gonna be much more subtle. On top of that most of us will never find the time to use it in an isolated fashion that would validate results in a scientifically meaningful way.
The differences between CJC1295 and CJC1295 without DAC(ModGRF) in regards to "bleed time" and such are debated in the literature and probably worthy of further exploration, I am only talking about the Mod version.
So here is what I
think:
Most valuable use of it is for liberating fats and then burning them free fats up during fasted am cardio. 100mcg ModGRF + 200mcg Ipa 1.5 hrs before cardio/activity.
Tendon health seems improved.
Skin health and appearance seems improved.
Possible sleep benefits, really hard for me to measure as my schedule is a huge mess.
Hypertrophy efforts? No dramatic or even noticeable advantages over abstaining from use, but again if not using in isolation how can you tell what is doing what? Def not worth the cost of chasing this aspect of it in my opinion though unless you are made of money.
Never done bloods related to this but I believe the claim that there is a small bump in GH output, I think it would be foolish of me to compare it to some guesstimated amount of exo GH though. Not a higher bump than the max you could produce naturally, different than Sermolin which can overproduce iirc.
Sorb if you are asking because of anything to do with your gut issues I think it would be worth a shot but as a long term slow treatment vs jumping on GH as a quicker fix when you are having trouble.
That's all I can think of right now, happy to discuss more if you wish.
