MOTS-c is a mitochondrial-derived peptide with genuine academic momentum in exercise physiology and metabolism, including early human work. It represents the rare corner of this market where the science is younger than the sales.
MOTS-c has the weakest top end of any compound we have upgraded to a full page: the best score in the record is 42, and the board drops into the 20s from third place down. This is not a stale-data problem, since all five leaders published tests in July or August 2026. It is a depth-and-results problem: records of four to nine tests each, with enough misses in them to keep confidence low across the board. Until a vendor builds a deeper clean record, treat every MOTS-c purchase as unverified-by-default and check the specific batch, not the seller’s average.
Pricing is tight and low, $0.50 to $0.80 per milligram across the scored leaders, so price will not help you choose here. One line every athlete should read twice: WADA prohibits MOTS-c by name as a metabolic modulator, and anti-doping labs test for it. For anyone subject to doping control, this compound is a positive test in a vial regardless of what it does or does not do for mitochondria.
Thin per-vendor records combined with actual misses. Our scoring is confidence-adjusted, so a shallow record with failures lands hard. The scores describe the published evidence, not a verdict on the molecule.
No. It is an active research area with early-stage human studies and no approved use anywhere.
Yes, explicitly. WADA lists it by name and it is detectable in testing. This is one of the clearest hard-no compounds for tested athletes in our entire index.
