If you already have a vial

Products sold as research-use-only are unapproved drugs. Nothing required the seller to verify identity, purity, sterility or concentration. That is the practical risk, more than the compound itself. Worth discussing with your clinician before you continue, and worth logging so your labs can be read against it.
