Prescription & Legal Access
PT-141 is a prescription-only medication in the U.S. It must be prescribed by a licensed healthcare provider and dispensed through a licensed pharmacy. Off-label prescribing is at the provider's discretion within their scope of practice. Any source selling PT-141 without a prescription is operating outside FDA regulations.
Section 503A Compounding
Section 503A of the Federal Food, Drug, and Cosmetic Act governs which substances compounding pharmacies may use. Substances are placed into one of three categories: Category 1 (eligible for compounding), Category 2 (significant safety concerns — prohibited), or Category 3 (under review).
WADA & Anti-Doping Status
PT-141 is not currently listed on the WADA Prohibited List. However, WADA updates its list annually, and substances may be added under the catch-all "S0 Non-Approved Substances" clause if they have no current approval for human therapeutic use. Athletes should check the current WADA Prohibited List before use.
