Tryptamines. DPT.


N,N-DPT is a novel synthetic tryptamine and is the dipropyl structural homologue of N,N-dimethyltryptamine (DMT). Placebo-controlled, human clinical trials have indicated dipropyltryptamine as a potentially beneficial adjunct in the psychotherapeutic treatment of terminally ill cancer patients [1] [2] [3], as well as alcoholics [4] [5] [6]. It is NOT intended for human consumption, and is strictly for laboratory reagent or forensic analysis purposes ONLY. It is available only as the hydrochloride salt. All prices are listed in Canadian dollars.
