MOTS-c is named on the world list
The World Anti-Doping Agency (WADA) sets a prohibited-substance list for world sport.
Its list in force during 2026 names MOTS-c as prohibited both during and outside competition.
“Prohibited” means banned under those sports rules.
The next list keeps the same ban
The published WADA list taking effect on January 1, 2027, also bans MOTS-c. That list was available as of September 30, 2026.
“Natural” does not answer this question
The body making its own MOTS-c does not remove the sports prohibition on the named substance.
Ask which organisation governs your event. Bring the exact substance name into that discussion rather than relying on a broad “peptide” label.
A medical exemption is a separate process
The US Anti-Doping Agency describes a therapeutic use exemption: permission for a banned medicine needed for an illness.
As of September 17, 2026, athletes in its Registered Testing Pool, Clean Athlete Program or Education Pool needed permission before treatment. These are groups of athletes covered by USADA’s drug-testing and education programmes.
Other athletes are directed to its pre-check form to find out whether they need that permission.
That does not promise an exemption for MOTS-c. Ask the relevant sports body about your case.
Keep this in mind
As of September 30, 2026, WADA banned MOTS-c both during competition and at other times.
