- FDA: BPC-157 is not approved. It was classified as a Category 2 bulk drug substance in 2023 and cannot be legally sold as a drug, food, or dietary supplement. TB-500 is also not approved and was not formally listed on the FDA Category 2 bulk drug substances list, but it is not authorized for human consumption.
- WADA: BPC-157 is prohibited under S0 (Non-Approved Substances) and was explicitly named on the 2022 Prohibited List. TB-500 is also prohibited under S0 (Non-Approved Substances) and is classified as a non-Specified Substance banned in and out of competition.
- Compounding pharmacies: The FDA's Category 2 classification means compounding pharmacies cannot legally use BPC-157, though ongoing reclassification proceedings may change this. TB-500 is not available through licensed compounding pharmacies either, though it was not formally placed on the Category 2 list.
- Research chemical market: BPC-157 is widely available as a "research chemical" not intended for human use, and is legal to purchase in most jurisdictions under this designation. TB-500 has the same gray-market availability and is sold as a research compound with disclaimers against human use.
- For competitive athletes: Both peptides are unequivocally prohibited by WADA. A positive test for either substance typically results in a 4-year ban for a non-Specified Substance violation. USADA has specifically warned athletes about BPC-157 contamination in supplements.
- For non-athletes: The legal landscape is a gray area. Neither peptide can be legally prescribed, sold as a supplement, or marketed for human use. In practice, both are widely purchased through research chemical vendors and administered under physician supervision at anti-aging and regenerative medicine clinics. This is an off-label, unregulated use case that falls outside established FDA frameworks.
