First of all, I meant HGH but say GH because I'm lazy... lol
Seriously, use GH when referring to the actual hormone in your body, and use HGH when referring to the exogenous compound.
IGF1-LR3 is the compound used for site specific injuries.
If you're asking for suggestions on specific brands I can't answer that. Only because I have no idea. It's been a few years since I ran actual HGH.
I've tried the peptides... GHRP + GHRH and it does work albeit to a lesser degree. But the peptides work differently than actual HGH. If I'm correct, the peptides stimulate your natural GH release from your body as opposed to putting exogenous GH in. There are plenty of people here who are more well versed in peptides than me. Check out the peptide forum for more info on them if you're interested.
