❓ Scientific FAQ

Q1: What is the metabolic pathway?
A: Primary metabolism via hepatic deacetylation to 4-HO-MET, followed by glucuronidation.

Q2: How does the receptor affinity compare to psilocin?
A: 5-HT₂A binding affinity is 1.8x lower than psilocin, but with higher selectivity.

Q3: What are the optimal storage conditions?
A: Under inert gas at -20°C in amber vials with molecular sieve.

Q4: Are there any known genotoxic risks?
A: Ames test results show no mutagenic activity at <100 μM.
