TL;DR — Research Summary

MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA. Its effects on metabolism and exercise capacity come from mouse studies, and no peer-reviewed trial giving MOTS-c to people has been published. The human studies measure the body's own MOTS-c levels, which fall with age, are lower in type 2 diabetes, and rise with exercise.[1][2][3] It is not an approved medicine. In July 2026 an FDA advisory committee recommended, 7 to 5 with two abstentions, that US compounding pharmacies be allowed to use it, against FDA reviewers' advice; no rule has followed.[4][5] WADA prohibits it at all times.[6]

In Dubai, MOTS-c is sold mostly as clinic therapy, and online as research material. Remy Research lists the MOTS-C 10mg vial at AED 260 (AED 220 at the 5+ tier) to a ≥99% HPLC line standard, with no batch-specific Janoshik report published yet. Material is supplied for in-vitro laboratory research only — not for human or veterinary use.

Compliance note: this page is a research review, not a treatment guide. It does not provide human-use dosing, therapeutic recommendations, or any clinical-use instructions, and should be read in the same non-therapeutic frame required across Remy's research content.

What MOTS-c Is

MOTS-c stands for "mitochondrial open reading frame of the 12S rRNA type-c". It is a 16-residue peptide, Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Arg (MRWQEMGYIFYPRKLR), coded within the mitochondrial 12S rRNA gene rather than in the cell nucleus.[1] PubChem lists it as C101H152N28O22S2, about 2174.6 g/mol, CAS number 1627580-64-6, PubChem CID 146675088.[2]

It was described in 2015 by a University of Southern California group, who reported that it acts mainly on skeletal muscle through the folate cycle and AMPK.[3] The same group later showed that under metabolic stress it moves into the cell nucleus and affects gene expression.[7] The full mechanism review is on the MOTS-c research page, and its relationship to SS-31 is covered in MOTS-c vs SS-31.

FDA's 2026 review called MOTS-c "not well-characterized": it has no standard name, and no impurity, aggregate or endotoxin specifications or certificates were submitted.[4] That is the strongest neutral reason to ask any supplier for batch-level data.

The Evidence, Sorted by Type

Evidence type What exists What it can show
Mouse studies Less diet-induced obesity and insulin resistance; better physical capacity in older mice Hypotheses for human study
Human levels Blood MOTS-c lower with age and in type 2 diabetes; rises with exercise and heat Association, not effect
Genetics An East Asian mitochondrial variant that alters MOTS-c is linked to type 2 diabetes in men Association, not effect
Human trials No published trial of MOTS-c; one analog, CB4211, finished phase 1 in 2021 Nothing yet for MOTS-c

In mice, MOTS-c prevented diet-induced obesity and insulin resistance, and late-life treatment improved physical capacity.[3][8] Human studies measure the body's own MOTS-c. Plasma levels fall with age; levels are lower in people with type 2 diabetes, in a cohort from Doha, Qatar; and they rise after endurance exercise and, in a study by Doha's Aspetar sports hospital with UAE University, after repeated heat exposure.[9][10][11][12] A mitochondrial DNA variant that changes one amino acid in MOTS-c was linked to type 2 diabetes in men across three cohorts.[13] These measurements need care: a doping-control laboratory that built a validated mass-spectrometry test could not confirm the levels reported by commercial ELISA kits.[14]

No peer-reviewed trial giving MOTS-c to people has been published. The closest is CB4211, an analog developed by CohBar, which completed a phase 1 study in 2021; its results appeared only in a company press release.[15][16] CohBar was declared a public shell company and delisted from Nasdaq in late 2023, and no further development of CB4211 was found.[17]

What Has Been Published on Safety

Regulatory Status in 2026

Where MOTS-c stands as of October 7, 2026.
  • United States. Not FDA-approved and not on the 503A Bulks List. It was moved off FDA's Category 2 compounding list in 2026 after its nominations were withdrawn.[19] On July 23, 2026 the Pharmacy Compounding Advisory Committee voted 7 to 5, with two abstentions, to recommend adding it, for obesity and osteoporosis; FDA's reviewers had proposed not adding it. The vote is advisory, and no rule had been published by October 7, 2026.[5][20]
  • European Union. No entry in the EU register of centrally authorised medicines.[21]
  • United Arab Emirates. We found no UAE registration for MOTS-c as a medicine. This is not a legal opinion; see the Dubai legality brief.
  • Sport. Named by WADA under S4.4.1, activators of AMP-activated protein kinase, on the 2026 and 2027 Lists, and prohibited at all times. A validated doping-control test exists.[22][14]

Remy Research publishes batch-specific Janoshik reports for its Retatrutide products in the lab results library. The MOTS-c line is not yet covered by a published batch report, and this page does not imply otherwise. Delivery terms across the emirates are on the delivery page; SS-31 has its own Dubai guide.

Checking a MOTS-c Supplier in the UAE

Most UAE pages selling MOTS-c quote "99% purity" or "COA available" without a batch number or a named laboratory. Before ordering from any supplier, including this one, check:

MOTS-c Dubai FAQ

Where can I buy MOTS-c in Dubai?

In Dubai it is offered mostly as clinic therapy and by online research-peptide suppliers. For research material, Remy Research lists a 10mg vial, a 20mg pen and two Genovare pens, supplied for in-vitro laboratory research only and not for human or veterinary use. Whatever the source, ask for a dated, batch-linked certificate with mass-spectrometry identity before ordering.

Is MOTS-c legal in the UAE?

We found no UAE registration for MOTS-c as a medicine. It is not FDA-approved and has no central EU authorisation. This is a status line, not legal advice; the Dubai legality brief covers the wider rules.[4][21]

Is MOTS-c FDA-approved?

No. On July 23, 2026 an FDA advisory committee voted 7 to 5, with two abstentions, to recommend allowing US compounding pharmacies to use MOTS-c, after FDA's reviewers had proposed against it. The vote is advisory, and no rule had been published by October 7, 2026.[5][20]

Is MOTS-c banned in sport?

Yes. WADA names MOTS-c under S4.4.1, activators of AMP-activated protein kinase, on the 2026 and 2027 Prohibited Lists, prohibited at all times. A validated mass-spectrometry doping test exists.[6][14]

Has MOTS-c been tested in humans?

No peer-reviewed trial giving MOTS-c to people has been published. Human studies measure the body's own MOTS-c, which is lower with age and in type 2 diabetes and rises with exercise. An analog, CB4211, completed a phase 1 study in 2021, with results only in a press release; its developer was delisted in 2023.[9][10][16]

What should a MOTS-c certificate of analysis show?

A batch number matching the vial, a named laboratory and a date; HPLC purity; mass-spectrometry identity at about 2174.6; and ideally endotoxin and net peptide content. FDA cited missing impurity, aggregate and endotoxin data among its reasons for calling MOTS-c not well characterised.[4]

Is Remy Research MOTS-c third-party tested?

The ProPeptide vial and pen are supplied to a ≥99% HPLC line standard, but no batch-specific Janoshik report has been published for them yet. Independent testing has not been supplied for the Genovare pens. Published Janoshik batch reports currently cover the Retatrutide range.

Is MOTS-c the same as SS-31?

No. Both are discussed as mitochondrial peptides, but MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA, while SS-31 (elamipretide) is a synthetic four-residue peptide that targets the inner mitochondrial membrane. The MOTS-c vs SS-31 comparison covers the differences.
