Where to buy MDOH (MDH) for sale online


3,4-Methylenedioxy-N-hydroxyamphetamine, MDOH or MDH, belongs to the entactogen, psychedelic, and stimulant categories within the phenethylamine and amphetamine chemical families. This compound serves as the N-hydroxy counterpart of MDA and the N-desmethyl analog of MDHMA. Alexander Shulgin carried out the initial synthesis and evaluation of MDOH.
In his influential book, “PiHKAL” (Phenethylamines I Have Known And Loved), Shulgin detailed MDOH, stating that its typical dosage ranges from 100 to 160 mg, with effects lasting approximately 3 to 6 hours. According to Shulgin, MDOH elicits profound psychedelic experiences and enhances one’s appreciation of beauty and nature. However, he also noted specific adverse effects reminiscent of those associated with MDMA (commonly known as “Ecstasy”), such as difficulties with urination and internal dryness.
