Buy O-DSMT Pure (O-Desmethyltramadol) is a high-purity research chemical powder of the opioid class. Laboratories and researchers use it to study mu-opioid receptor pharmacology, analgesic mechanisms, and structure-activity relationships of tramadol metabolites.
What is O-DSMT?
O-DSMT (O-Desmethyltramadol, also known as Desmetramadol) is the primary active metabolite of the prescription opioid tramadol. It is significantly more potent than tramadol itself and acts as a strong mu-opioid receptor agonist. Originally studied in the context of tramadol metabolism, it has emerged as a standalone research chemical sold strictly for laboratory and research purposes only.
Chemical Properties of Buy O-DSMT Pure
- IUPAC Name: 3-[(1R,2R)-2-[(dimethylamino)methyl]-1-hydroxycyclohexyl]phenol (racemic mixture)

- Molecular Formula: C₁₅H₂₃NO₂
- Molar Mass: 249.35 g/mol (free base)
- Appearance: White to off-white crystalline powder (often as HCl salt)
- Solubility: Soluble in water and organic solvents like ethanol or DMSO
- Key Features: Much higher affinity for mu-opioid receptors (up to 200x greater than tramadol) with dual opioid and monoaminergic activity.
Effects (Research Observations)
O-DSMT primarily acts as a potent mu-opioid receptor agonist. Reported research and observations include:
- Strong analgesic (pain-relieving) effects
- Euphoria, relaxation, sedation, and mood elevation
- Typical opioid-like effects including respiratory depression at higher doses
- Onset: 30–60 minutes (oral)
- Duration: 6–8+ hours
Important Note: These are not approved medical effects. O-DSMT carries serious risks including respiratory depression, sedation, dependence, tolerance, withdrawal, and potential for overdose. Strictly for research use only — not for human consumption.
Legality of Buy O-DSMT Pure
O-DSMT is controlled or restricted in many jurisdictions:
- United Kingdom: Class B
- Germany: NpSG (industrial and scientific use only)
- United States: Not federally scheduled but may fall under the Federal Analogue Act if intended for human consumption
- Other Countries: Restricted in various EU nations, Canada, Australia, and elsewhere under opioid or NPS laws
Always verify current local laws before any purchase or handling. Vendors sell it exclusively for laboratory/research purposes.
