Albert Hofmann isolates psilocybin
Sandoz chemist Albert Hofmann identifies and synthesizes psilocybin from Psilocybe mexicana, establishing the structural scaffold modern research is built on.
Psilocybin
Natural psilocybin, GMP-manufactured.
What the molecule is, how it's made, and why pharmaceutical-grade purity separates regulated-access supply from everything else.
01The moleculeTryptamine class
- Formula
- C₁₂H₁₇N₂O₄P
- Molecular weight
- 284.25 g/mol
- IUPAC name
- [3-(2-dimethylaminoethyl)-1H-indol-4-yl] dihydrogen phosphate
- 1Phosphate esterHydrolyzed in vivo to psilocin (4-OH-DMT) — the active 5-HT2A agonist.
- 2Indole coreTryptamine scaffold; same structural family as serotonin.
- 3N,N-dimethyl tailDetermines receptor affinity and lipophilicity.
Psilocybin is a prodrug: once ingested, the phosphate ester is hydrolyzed to psilocin, the active compound that binds to the 5-HT 2A serotonin receptor. Structurally, it's a tryptamine — the same scaffold underlying serotonin itself — which is why psilocybin's pharmacology is so tightly coupled to the serotonergic system.
Natural psilocybin is extracted from Psilocybe mushroom species rather than synthesized from petrochemical precursors. For a pharmaceutical product, the distinction matters at the regulatory level: extracted APIs carry a different impurity profile and different quality-control requirements than synthetic equivalents.

03Clinical posture
100M+
TRD patients globally
Treatment-resistant depression: patients who have failed ≥2 antidepressant trials.
25mg
Typical clinical dose
Single oral dose in the large phase-2 TRD trials (COMP360, usona).

Molecule isolated
Sandoz / Albert Hofmann; seven decades of science, six decades of regulatory pause.
04Optimi's role
Supply, not discovery
We manufacture the medicine. We don't run the trials.
Clinical development of psilocybin as a drug is happening at specialist drug-developers — Compass, Usona, atai affiliates. Our role sits downstream of that: deliver GMP-certified natural psilocybin to programs that have earned authorization to prescribe it.
What GMP buys you
Consistency, auditability, regulated-access eligibility.
A Health Canada Dealer's Licence plus GMP certification is a cumulative regulatory asset. Each access-program partner we qualify for is the output of a multi-year path that's hard to replicate and central to commercial supply.
