YK-11 as Myostatin Inhibitor?

I’ve been doing a lot of research on different compounds and supplements for bodybuilding lately and found my trusted gear supplier has a bunch of sarms & vials of follistatin.

From what I have read it seems MK-11 increases follistatin production which in turn decreases myostatin which apparently limits how much / how fast you can gain. I have read that effectively administering actual follistatin via injection in humans is sketchy science at best but i know that there are people doing it. I also know that SARMS are in a sketchy category of research also but i’m strongly considering trying something to boost follistatin for later cycles, or maybe even in-between cycles. I’m naturally the tall skinny ectomorph type and hoping to trick my body into giving me results / composition closer to a mesomorph.

Anybody have any experience with, or links to bodybuilding focused articles on either of these compounds?

I have been on their MK - 677 (GH secretagogue) for about 2 months and off cycle for about a month. so far i have sustained all of my weight and gained about another 5lbs without any noticeable fat gain or bloating.
