This is intriguing: "RAD-140, however, has shown an anabolic/androgenic ratio of about 90:1, and actually antagonizes (partially blocks) the effect of testosterone on the prostate. That’s an impressive demonstration."
"t’s a very interesting compound, and could be of value as part of a steroid stack due to its partial testosterone blocking effect in the prostate."
Some of the stuff I have read would say yes to your question Mindless. But like Dr. Jim stated, I don't think there is enough info out there to substantiate the claims. I may try it coming up very soon. But SARM's are a little scary because of the unknown. Also, why aren't they on the mainstream market?
