It is not for human or veterinary consumption, and not for diagnostic or therapeutic use. By ordering, you confirm you are a qualified researcher and will handle these materials accordingly.

Vials arrive sealed with a tamper-evident cap and are held in cold storage at -4°F until they leave our facility, which preserves the compound through transit.
