WHAT IS MT-45 AND ITS CHEMICAL FOUNDATIONS?

MT-45, chemically identified as 1-cyclohexyl-4-(1,2-diphenylethyl)piperazine, was originally synthesized in the mid-1970s by Dainippon Pharmaceutical Co. in Japan. Moreover, its structure features a piperazine core substituted with a cyclohexyl group and a 1,2-diphenylethyl moiety, setting it apart from morphinan or fentanyl-derived opioids. Consequently, MT-45 exists as a racemic mixture, with the (S)-enantiomer responsible for most analgesic activity. How to buy MT-45 online in Canada
