Competitive sport
Sport rules ask a different question from prescribing
If you compete, take the exact substance name into a conversation about your sport’s rules. A care discussion does not finish that separate check.
The world-sport list is dated
The World Anti-Doping Agency, called WADA, publishes sport’s Prohibited List: substances and methods banned under its rules. Its 2026 list was the one in force at the September 2026 check.
WADA’s published 2027 replacement takes effect January 1, 2027; it is not the current list before that date.
The 2026 list also names TB-500 among banned growth factors. BPC-157, ipamorelin, CJC-1295, sermorelin and TB-500 are banned during training and other time away from competition as well as in competition.
A watch list tracks use without imposing a ban
At the September 2026 check, WADA tracked semaglutide and tirzepatide use through urine testing to look for patterns of misuse. This is called monitoring; it does not itself ban them, and neither drug was named on WADA’s Prohibited List.
That is not a clearance for every sport or every product with a similar name.
Ask the body governing your competition which process applies before relying on a prescription alone.
US college sport uses its own rules: the NCAA’s 2026–27 list names BPC-157, TB-500 and ibutamoren, also called MK-677.
