I have been trying as much info on sarms as I can. I have been working out solidly for two years, and am 20 years old (21 soon). I have seen much contradictory info on sarms in general, some stating no pct required, does not affect hpta, others saying it's dose dependent. I am guessing it's still too knew to tell. I understand that some users get minor shutdown on s4, so it is affecting hpta in some way but overall seems to have less sides than aas. Ostarine may have the potential to have even less sides/shutdown. Is there any vet or experienced user that would know if ostarine would be safe for a 20 year old to take, if nolvedex/ clomid is on hand?
