O-DSMT Powder (O-Desmethyltramadol) For Research Use Only. Not Intended for Diagnostic or Therapeutic Use.
What is O-DSMT Powder
O-DSMT (O-Desmethyltramadol), also known as desmetramadol or M1, is the main active metabolite of tramadol. It functions as a potent Îŧ-opioid receptor agonist, providing significantly stronger analgesic effects than the parent drug. In research contexts, O-DSMT powder is used for studying opioid pharmacology, analgesia mechanisms, metabolic pathways, and receptor binding characteristics. Its high purity powder form enables accurate dosing for preclinical studies.
