To be honest, I haven't researched the studies yet, so Im not the guy to ask. I downloaded quite a few studies from PubMed a year ago, but haven't got around to reading them - you know my schedule. Its hectic.
When anything "New" enters the market, I tend to let others be the Guinea pigs. I used this approach before I jumped into the deep end of the pool with peptides - Frag 176-191 for example. And that worked out great.
I've waited a little longer with the Sarms as I'm scared of messing with my vision.
