MOTS-c for CrossFit athletes: what exercise research measures
CrossFit performance combines strength, skill, pacing and endurance. A peptide’s association with exercise physiology is not proof that administering it improves a workout or competition result.

The evidence behind the claim
The study combined observations of endogenous MOTS-c after human exercise with intervention experiments in mice. The human observations were not a trial of administering MOTS-c.
Athletes should check the rules applying to their sport and the current prohibited list; a research label does not establish eligibility.
What is missing from a performance claim
Mouse running experiments are not CrossFit trials, and human measurements after exercise are not evidence of benefit from dosing. A sport-specific study would need a defined intervention, a comparison group and reproducible performance tests rather than a single unusually good training session.
How to evaluate relevance
Check whether training history, workload, nutrition and recovery were comparable between groups. Improvement in one endurance task cannot establish better lifting technique or mixed-modal performance. Competition eligibility is a separate issue that must be checked with the relevant sport authority.

Frequently Asked Questions
Does exercise-induced MOTS-c prove that additional MOTS-c is useful?
No. Natural production and externally administered exposure are different questions.
Can a research-use label establish that a product is allowed in competition?
No. Eligibility depends on the applicable rules and substance classification, not the vendor’s label.
