No. No MOTS-c product has been approved by the U.S. Food and Drug Administration for any use. That means nobody has shown regulators that it’s safe and effective for any medical condition.

MOTS-c is best described as investigational: it’s still being researched.

Question 2: What’s happening in clinical trials?

A registered phase 2a trial (NCT07505745) is testing whether 12 weeks of investigational MOTS-c improves insulin sensitivity compared with placebo in adults with prediabetes and overweight or obesity [1]. Key facts from the trial record [1]:

Sponsor: Hudson Biotech
Location: China
Planned size: about 120 participants
Status: recruiting, with primary completion estimated for February 2027

This is the kind of study that can eventually show whether MOTS-c has measurable effects in people. Until results are published, we simply don’t know.

Question 3: What did FDA’s advisers discuss?

Some pharmacies make (“compound”) medicines from raw ingredients. To use a raw ingredient that isn’t part of an approved drug, it generally has to be on an official list.

On 23 July 2026, FDA’s Pharmacy Compounding Advisory Committee discussed whether MOTS-c (free base and acetate) should be added to the list used by traditional compounding pharmacies, called the 503A bulks list [2]. The uses FDA reviewed for MOTS-c were obesity and osteoporosis [2]. The same day, the committee also discussed BPC-157, KPV and TB-500 [2].

What you need to know about this meeting:

The committee gives advice. FDA makes the final decision later.
Even if MOTS-c were added, that wouldn’t make it an “approved drug”. It would only mean pharmacies could compound it under specific conditions, for the uses reviewed.
We haven’t yet verified the official outcome from FDA records, so we won’t guess. We’ll update this page when we have.

Question 4: Can athletes use MOTS-c?

No. The World Anti-Doping Agency (WADA) Prohibited List names MOTS-c explicitly. It sits under section S4.4.1, activators of the AMP-activated protein kinase (AMPK), within “hormone and metabolic modulators”, which are prohibited at all times [3].

Athletes in sports that follow WADA rules can face a ban for using MOTS-c, even out of competition.

Question 5: What about “research peptide” websites?

Some websites sell MOTS-c labelled “for research use only”. Here is what that label does and doesn’t mean:

These products aren’t approved for people.
Nobody checks what’s really in the vial: how pure it is, whether it’s sterile, or how strong it is.
Most of the research on MOTS-c comes from mice, not people (see our beginner’s guide).

We don’t link to sellers, and we don’t share dosing information.

The simple summary

MOTS-c is a fascinating research molecule. It isn’t approved, it’s banned in tested sport, and its legal status for compounding is still being decided. The best way to learn whether it works is from properly run clinical trials, like the one now recruiting.

Question 6: What about outside the U.S.?

Rules differ from country to country, and we haven’t yet finished a verified, country-by-country review. The anti-doping rule is the exception: WADA’s Prohibited List applies to athletes in WADA-code sports worldwide [3]. Outside the U.S., MOTS-c’s status is set by each national medicines regulator.

How we keep this page accurate

We re-check the FDA advisory committee page, the WADA list and the trial record whenever we hear of a change, and we update the “status checked” date below each time.

Status checked: 18 October 2026.
