Im 21 178 lbs been lifting for three years not sure what percentage body weight .. but Ive been taking mk gw and Lgd at 30 mg a day for about 10 weeks and Im about to run out. I have liquidex and was given this by my source and was planning on running that for pct. I went to visit him the other day and since Ive bought a lot from him he threw me some s4. Initially I just planned on keeping it but on further exploration and research it didnt seem that there would be any major conflict in me taking this directly after my cycle that Im currently on. But also Im not a scientist and dont understand every single chemical reaction of the body, receptors, and of the SARM itself ... so I made an account and decided to get some input.... thanks in advance
