The official WADA prohibited list explains which substances and methods are prohibited and when. S0 includes BPC-157; S2 addresses peptide hormones, growth factors, and related substances. Consult each category in full.

Check the applicable edition

WADA updates the list at least annually. The published edition may take effect the following January, so athletes should check the effective date relevant to their situation.

Testing and sanctions are separate questions

This summary makes no claim about laboratory detection windows or a mandatory four-year sanction in every case. Refer questions about a substance, therapeutic use exemption, or potential rule violation to the relevant anti-doping organization.
