I was looking into these as well, until I read on irevolution steroids blog how the moderator admitted that some of these SARMS can shut you down FOREVER- meaning you're hormones are now dead for remainder of life . Some of them SARMS required a 3 month PCT, not 3 weeks, months. After those two statements, I was completely turned off. But that's just my feelings. Read fine print and those things are possibly a lot more dangerous than 1,st appearance.
