Where to buy 1,3-Benzodioxolyl-N-methylpentanamine (MBDP) for sale online


N-Methyl-1,3-benzodioxolylpentanamine (MBDP; also referred to as Methyl-K, UWA-091), scientifically known as 3,4-methylenedioxy-α-propyl-N-methylphenethylamine, is a psychoactive compound belonging to the phenethylamine chemical class. This substance is the N-methyl counterpart to 1,3-benzodioxolylpentanamine (BDP; K). Methyl-K synthesis can be credited to Alexander Shulgin, often affectionately called “Sasha” Shulgin. Shulgin’s comprehensive work, PiHKAL (“Phenethylamines I Have Known And Loved”), provides insight into this compound. According to PiHKAL, the minimum effective dose of methyl-K is listed at 100 mg, although the duration of its effects remains uncertain. Unfortunately, our understanding of Methyl-K’s pharmacology, pharmacokinetics, effects, and potential toxicity is limited.
