FDA compounding assessment in the cited records. FDA's July 2026 briefing evaluates MOTS-c-related bulk drug substances for pharmacy compounding. The briefing is an advisory-process assessment, not a final regulatory determination.↗
Review source snapshots checked September 15, 2026 · Integrity checked September 15, 2026.
Three selected human reports measured naturally occurring MOTS-c during exercise studies or in patients with coronary endothelial dysfunction. None of these reports tested administering MOTS-c to people.↗↗↗
What the reviewed sources report
Human studies associate endogenous MOTS-c with exercise or vascular measurements. Exercise interventions and biomarker associations do not demonstrate the efficacy or safety of administered MOTS-c.↗↗↗
What remains unresolved?
What evidence directly evaluates administered MOTS-c in humans, separately from exercise and endogenous biomarker studies?↗↗↗
How do assay methods, confounding and population differences affect observed associations?↗↗↗
The agency assessment found preclinical rather than treatment evidence
FDA’s July 2026 briefing did not identify studies administering the nominated MOTS-c substances to humans. It distinguished that absence from rodent and cell studies relevant to proposed metabolic and bone effects. FDA PDF pp. 25, 31 ↗
More findings and the sources behind them
Selected FDA advisory-briefing sections, not a final agency ruling. The source date identifies the committee meeting (July 23–24 for the 2026 packages), not a new approval or final decision.
Bone-cell findings do not establish fracture prevention
The discussed bone experiments used cultured cells and rodent models. They do not demonstrate reduced fractures or a clinical osteoporosis benefit in people. FDA PDF pp. 24, 31 ↗
Mechanistic uncertainty limits extrapolation
FDA noted missing in-vivo dose-response evaluation and uncertainty about the molecular targets. It considered the clinical relevance of the preclinical findings unresolved. FDA PDF pp. 25, 31 ↗
The recommendation concerns the nominated substances
The briefing weighed against inclusion of MOTS-c free base and acetate on the 503A bulks list and described characterization gaps. This staff proposal is distinct from a final agency action or an assessment of every related analogue. FDA PDF pp. 1, 32 ↗
What remains to be checked
Check subsequent advisory records and any final FDA action separately from the staff briefing.

Supervised synthesis
What do selected human studies report about MOTS-c?
Three selected human reports measured naturally occurring MOTS-c during exercise studies or in patients with coronary endothelial dysfunction. None of these reports tested administering MOTS-c to people.123
Bottom line from this bounded source set
Human studies associate endogenous MOTS-c with exercise or vascular measurements. Exercise interventions and biomarker associations do not demonstrate the efficacy or safety of administered MOTS-c.123
Reviewed study record
Acute exercise and circulating peptides
Design
Participants were randomized to endurance exercise, resistance exercise or a control group, with blood and muscle measurements.1
Population
Thirty participants were assigned to three groups of ten.1
Outcomes reported
Humanin increased after endurance exercise; MOTS-c showed a trend toward an increase.1
Limitations
The intervention was exercise, not MOTS-c administration. A trend is not a demonstrated clinical benefit, and the small study measured short-term biomarkers.1
Reviewed study record
Exercise in breast cancer survivors
Design
A secondary analysis of a randomized 16-week exercise-versus-usual-care study measured circulating MOTS-c.2
Population
The analysis included 25 Hispanic and 24 non-Hispanic White breast cancer survivors.2
Outcomes reported
MOTS-c increased in the non-Hispanic White subgroup and was associated with changes in metabolic measures; a comparable increase was not reported in the Hispanic subgroup.2
Limitations
Small subgroup analyses and baseline differences limit interpretation. Associations do not establish that MOTS-c caused the metabolic changes, and no peptide was administered.2
Reviewed study record
Coronary endothelial dysfunction
Design
An observational human comparison measured endogenous MOTS-c; separate experiments exposed rodent vessels to the peptide.3
Population
Forty patients undergoing angiography for recurrent angina were classified into two groups of twenty by endothelial function.3
Outcomes reported
Circulating MOTS-c was lower in patients with endothelial dysfunction and correlated with vascular function measures.3
Limitations
The human findings are associations. Exposure experiments used rodent tissues, so they do not establish a therapeutic effect or safety in people.3

The cited status sources were checked through July 29, 2026. This answer changes only through the profile’s visible version and correction history.
PeptideScanner currently has no selected clinical trial records and safety records connected to this profile. That is a collection gap, not evidence that no such records exist.

Application counts reflect exact reviewed ingredient connections; Federal Register counts reflect exact reviewed peptide-name matches; DailyMed counts reflect listed SPL versions with retained ZIP receipts. “Published” describes this page’s indexing surface, not the state of scientific evidence.
We narrowed the status wording to what the dated FDA briefing establishes. A briefing prepared for an advisory process does not establish the current absence of a later final decision. Related substance identities remain distinct.
The Federal Register published notice 2026-07361, attributed to FDA and its parent HHS department, on 2026-04-16. Its official title is “Pharmacy Compounding Advisory Committee; Notice of Meeting; Establishment of a Public Docket; Request for Comments-Bulk Drug Substances Nominated for Inclusion on the Section 503A Bulk Drug Substances List,” and PeptideScanner's exact reviewed identity mapping connects the document to BPC-157, Emideltide, Epitalon, KPV, MOTS-c, Semax and TB-500.
PubMed lists PMID 26289118 in Aging cell as Journal Article, Research Support, Non-U.S. Gov't, with publication-date metadata of 2015-08-20 (day precision). PeptideScanner associated the retained record with the identity slug mots-c. These fields reproduce attributed bibliographic metadata and do not summarize or endorse the article's findings.
Counts and links describe PeptideScanner’s selected records. They are not rankings and do not establish research quality, safety, effectiveness, or medical relevance.
These links are based only on overlapping years and evidence lanes in PeptideScanner’s selected records. They do not imply that the peptides are medically or scientifically similar.
