I've been curious about MK-677 for a while and I had a question about it, on this forum people say its great for gaining mass however on other forums people say it won't help you gain mass instead you just get a lot of water retention. Can someone clear this up for me?
I want to use sarms to increase my lift's weight and apparently S4 is good for that. I can't get bloodwork done though, would it be fine to take sarms without getting bloodwork before and after? I am 20 if that is relevant.
