RAD 140 is very new, so there isn't a lot of real world data on it yet. However, it does look very promising, with an impressive anabolic to androgenic ratio of 90:1! This means that users can experience a wealth of muscle building effects without all the associated androgenic side effects.
RAD is powerful enough to limit the effect of testosterone on the prostate and other unwanted areas. It has even been shown to be more anabolic than testosterone, as well. Dosing appears to be in the 4mg to 12mg range, with optimal cycle length being 4 to 6 weeks. Given its shorter half-life (16 hours), RAD needs to be dosed at least twice daily.
