SARMX is booty.....just bullshit. DHEA is not a test booster, unless you're a 60 y/o man. Like BB said, DHEA can be converted to many compounds inside the body. The likelihood that DHEA will convert to testosterone in a young, healthy male is miniscule.
100% Gimmick. Even the real world pharmaceutical SARMS like S4 and Ostarine don't seem to do much for bodybuilders and are ridiculous when it comes to the price. You're money is better spent on creatine or AAS.
