Let me check jcem today at school, see if any literature exists that wouldn't otherwise be available without membership
found nothing bro im sorry, is it possible it has a different name?
i think thats all the names i am aware off... mostly know as GDF-8, myostatin, sometimes its called HMP.
its kind of like folli. gaining more muscle mass by inhibiting myogenesis. but what i have read of people using folli (fst-344) it seems they experience a more cutting effect. so i wondered if GDF-8 would be more benificial if you focus on gaining muscles mass, off season.
