BPC-157 and TB-500 are prohibited in sport at all times, in competition and out of competition. The reason is that the World Anti-Doping Agency counts them among prohibited substances: as substances not approved for human use and as growth factors. A ban can be imposed even without a positive test result.
This article explains on what basis these peptides ended up on the list and what that means for someone under anti-doping control. The general context of recovery peptides is given in the pillar article, and BPC-157 itself is covered in a separate article.
Why are BPC-157 and TB-500 on the prohibited list?
The World Anti-Doping Agency list covers not only substances with a proven performance-enhancing effect, but also those not approved for human use and growth factors that affect tissue regeneration. BPC-157 and TB-500 fit both descriptions. Neither is an approved medicine, and both are associated with the healing of tendons, muscle and blood vessels. What follows from that for injuries themselves is examined in the article on peptides and tendon and ligament injuries.
What do categories S0 and S2 mean?
Category S0 covers non-approved substances: molecules with no authorisation from any regulatory body for human use. Category S2 covers peptide hormones, growth factors and related substances. In anti-doping material TB-500 is described both as a category S0 substance and as a category S2 growth factor. For an athlete the consequence is the same: the prohibition applies all year round.
Does the prohibition apply only in competition?
The prohibition is not limited to competition. It covers these peptides all year, in the competitive season and outside it. That sets them apart from substances prohibited only on the day of an event.
Do you need a positive test to be sanctioned?
You do not. An anti-doping rule violation can be established without a positive sample, on other evidence: an admission, possession of a preparation or purchase records. There is a known case of a Canadian athlete who received a four-year ban for BPC-157 and TB-500 without a positive test.
What does this mean for someone who competes?
For a competitor under anti-doping control, using BPC-157 or TB-500 is a real risk of a ban lasting several years. That risk is not reduced by the fact that the peptide was bought as research material, nor by a test failing to detect it. The safety recommendations and legal information are collected on the legal warning page, and the wider legal picture in the article on the legal status of peptides. Before reaching for any peptide, check its status on the current World Anti-Doping Agency list.
Frequently asked questions
Is BPC-157 prohibited in sport?
Yes. The World Anti-Doping Agency counts it among substances prohibited at all times, in competition and out of competition.
Which category of the WADA list are these peptides in?
TB-500 is described both as a non-approved substance in category S0 and as a growth factor in category S2. In both cases the prohibition applies all year round.
Can you be sanctioned without a positive test?
Yes. A ban can be imposed on the basis of possession of a preparation, purchase records or an admission, without a positive sample.
Does buying a peptide as research material protect against a ban?
It does not. How a shop describes a product does not change the status of the substance on the anti-doping list.
Where this information comes from
The classification of TB-500 among non-approved substances and growth factors, the year-round prohibition, the possibility of a sanction without a positive test and the case of the four-year ban of a Canadian athlete come from material published by BSCG in February 2026. The statement that TB-500 appears on the World Anti-Doping Agency list in section S2 and is prohibited all year comes from material published by Superpower on 2 August 2026. The note that use of BPC-157 may result in an anti-doping rule violation comes from material of the Maryland Orthopedic Specialists practice. These pages were checked on 31 August 2026.
