A selective androgen receptor modulator developed by Radius Health. Investigational compound with no approved human use. High anabolic to androgenic ratio in preclinical studies. Currently in Phase I clinical trials for breast cancer.
RAD-140 is used in performance settings as a muscle-building compound by people who want anabolic effect without injectable administration and without what they perceive as the harsher side effect profile of traditional anabolic steroids. The oral administration and the theoretical tissue selectivity of SARMs make them appealing to a population tha...
RAD-140 is more commonly used alone or with other SARMs than in traditional anabolic stacks, partly because the population that gravitates toward SARMs is often specifically trying to avoid traditional injectables. When combined with other SARMs, it appears most often alongside MK-677 for combined anabolic and growth hormone secretagogue effects, o...
The absence of long-term human safety data is the central risk that the performance community consistently minimizes. RAD-140 has no completed Phase III trials, no approved human use, and the longest available human data comes from small Phase I studies and case reports, some of which describe signi...
