I have done 5 cycles so far and worked pretty good for me. I have used rad 140 for 2 of them and the 2nd cycle with rad I noticed my hair was taking very long to grow while on it and I was pretty much bald to start. So I want to stay away from rad because I donít want to lose hair. My goal is to cut some body fat from my stomach and build muscle still. What is a good stack I should do and how long. Right now I have LGD, ostarine , and mk- 677 and have not started anything yet.
