I asked Catlin to check if Amazon has allowed the products back yet again. Sure enough, Amazon continues selling dangerous steroids and stimulants banned in sports and at least one drug regulated by the DEA, M-Drol , which contains the anabolic steroid methasterone. It is illegal to sell methasterone without a prescription and a DEA license. The DEA warned about methasterone in 2011, and this specific product has been recalled , yet it keeps making its way back onto Amazon. Amazon also trades in many compounds that are dangerous to the human body and banned by anti-doping agencies but aren’t yet illegal. One example is trenavar, marketed as TR3N , which is a “prohormone” that the body converts into another active compound. That compound is trenbolone, a DEA-controlled anabolic steroid. There’s nothing unusual about prodrugs as pharmaceuticals. We use many prescription prodrugs in daily medical practice, all regulated by the FDA, that become active only when processed inside the human body . That the DEA can’t easily regulate prodrugs of scheduled substances like trenbolone is simply an artifact of the outdated legislation that created the agency.
