Where to buy MOTS-c in the UK: the sellers with a verifiable COA
The newest verifiable MOTS-c certificate on any UK seller's website is on Pureline Biolabs (purelinebiolabs.co.uk), analysed 22 Jul 2026 (task #209942 on Janoshik's site); 13 verified sellers hold one covering MOTS-c, listed newest first below. Of the 446 active UK sellers we audit, 38 (9%) publish their own verifiable Janoshik certificate of analysis, and this page lists which of them hold one covering MOTS-c, newest certificate first. It is a record of paperwork, not a recommendation: The Peptide Watch sells nothing, takes no money from sellers and links to none of them. MOTS-c is a mitochondrial-derived peptide studied in metabolic research. It is a newer, less commoditised compound, so genuinely independent testing is scarcer and a verifiable certificate matters even more. Purity and identity cannot be judged by eye, so an independent certificate you can check is the only real proof of what is in the vial.
The one test that matters for MOTS-c
Ignore the marketing. The question is simple: does the seller publish a verifiable Janoshik certificate that names the seller itself as the client? If it does, you can confirm an independent lab tested that batch. If it shows an in-house document, a borrowed certificate, or "COA on request", you cannot. Learn the two-minute check in how to verify a Janoshik COA.
Which UK sellers publish a verifiable COA
Of the 446 active UK research-peptide sellers we audit, only 38 (9%) publish their own verifiable Janoshik certificate. Any of them is where you can actually verify testing, for MOTS-c or any compound. A few: Lab77Peptides · Peptology Labs · Biovanta · Camo Chem · Biohackpeptides · Zenic Labs.

Audit findings, not recommendations. Every entry is a report covering MOTS-c that we opened on Janoshik's own site and that names the seller itself as the client; the date is the analysis date printed on the report where we have read it, otherwise the date the laboratory received the sample. The table below is the same ledger in full, so the two always agree. Not exhaustive: a vendor whose MOTS-c report we have not yet read is not listed.
The 17 verifiable MOTS-c certificates we have read, newest first
Each row was opened on Janoshik's own site by a real page load and transcribed. The client column is the name the laboratory printed; a certificate counts as a seller's own only when that name is the seller. The report date is the analysis date printed on the report where we have read it, otherwise the date the laboratory received the sample. The verify link opens the laboratory, never the shop. Audit findings, not recommendations.

What the 17 MOTS-c certificates show
We have read 17 Janoshik reports covering MOTS-c, published by 13 UK sellers. Each was opened on Janoshik's own website. All 17 name the seller itself as the client. 11 of the 17 are dated within the last six months. The newest is dated 22 Jul 2026 and the oldest 13 Nov 2025.
15 of the reports give a purity figure for MOTS-c. The figures run from 96.819% to 99.391%, and 9 of the 15 are at 99% or above. 2 reports test for heavy metals or endotoxins instead. A purity figure describes the sample the laboratory received, not every vial from that batch.
Read directly from the newest reports: Pureline Biolabs: task #209942, sample received 22 Jul 2026, 11.23 mg recovered at 98.123%, client Pureline Biolabs Ltd; Biohacklondon: task #168534, analysed 19 Jun 2026, 46.46 mg recovered at 99.234%, client BioHack London Ltd; Lab77Peptides: task #193656, analysed 19 Jun 2026, 9.86 mg recovered at 98.755%, client Lab77Peptides.co.uk.
A certificate is a batch document. The lines that matter are the compound (it must say MOTS-c, not only a batch code), the client (the shop, not its supplier) and the analysis date. A new batch is untested until a new report appears.
Questions people ask
Which UK sellers publish a verifiable Janoshik certificate naming MOTS-c?
As of 30 September 2026, 13: Pureline Biolabs, Lab77Peptides, Biohacklondon, Reta24, Thoroughbredlabs, Phoenixbiolabs, Camo Chem, Kensingtonlabs, Ascendpeptidesuk, Regenix Peptides, Imperialpeptides, Clinicore, Xlpeptides. Each has a report on Janoshik's own website that names the seller as the client and lists MOTS-c. That is a statement about paperwork, not a recommendation; The Peptide Watch does not recommend anywhere to buy MOTS-c.
How recent is the newest MOTS-c certificate from a UK seller?
The newest we have read is Janoshik task #209942, sample received 22 Jul 2026. It is published by Pureline Biolabs and names it as the client. A certificate covers one batch, so an old one says little about stock on sale today.
How do I check that a certificate for MOTS-c is genuine?
Four things: an independent laboratory is named; the client field names the seller you are buying from, not a supplier; the compound line says MOTS-c; and the report's task number and key open the same report on the laboratory's own website (verify.janoshik.com). A branded PDF with no laboratory name and no verification code fails on the first check, however professional it looks. The free COA Checker on this site runs the checks for you.
Is MOTS-c a licensed medicine in the UK?
Not a licensed medicine in the UK. Sold as a research chemical. CohBar stopped its analogue CB4211 after phase 1a/1b and merged; no other sponsor has a drug programme. The Peptide Watch does not give legal or medical advice.
Why does The Peptide Watch not say where to buy MOTS-c?
Because the site records paperwork, not recommendations. A verifiable certificate proves that a sample of one batch was tested. It does not prove the vial you receive matches it, and it says nothing about whether anyone should use MOTS-c. Listing which sellers publish a certificate you can check, and which publish nothing, is as far as the evidence goes.

The other 33 sellers: what they publish instead
- No named lab, nothing to verify: 16
- Shows a supplier's certificate, not its own: 3
- 'COA on request', nothing published: 2
- Claims testing but names no lab: 2
- Testing claimed, not yet evidenced: 2
- Anonymous / not its own: 1

The market for MOTS-c in the UK
Advertising. Google's Ads Transparency Centre shows 3 of these sellers running ads: Regenix Peptides, Kensingtonlabs, Thoroughbredlabs. Paid reach is where a new buyer meets a brand before meeting any certificate.
Companies. 21 of the 48 can be matched to a Companies House record; the median company is 10 months old and 11 were incorporated within the last year. A seller with no traceable company is not necessarily dishonest, but there is nobody to hold to its certificate.
Reviews. 13 of the 48 have a Trustpilot profile with a score; the median is 4.3, 3 sit at 4.5 or above and 1 below 3.0. A review score says who collects reviews, not who tests, which is why it sits next to a certificate and never instead of one.

What the research shows for MOTS-c, and what it does not
| Papers on PubMed | 255 |
|---|---|
| Indexed as rat or mouse studies | 92 |
| Indexed as clinical trials | 5 |
| Published since 2020 | 217 |
| Trials registered on ClinicalTrials.gov | 6 |
A real human peptide with a mostly preclinical record. MOTS-c is encoded in mitochondrial DNA. PubMed indexes 255 papers, 92 of them rat or mouse studies; the 5 papers indexed as clinical trials are small, and 4 of the 6 registered studies on ClinicalTrials.gov have no drug phase at all.
The one drug programme was abandoned. CohBar took an analogue, CB4211, through a phase 1a/1b study in fatty liver disease and obesity, reported in 2021, then said the formulation was not suitable for further development and suspended the programme before merging. No company is developing MOTS-c today.
What that means for a buyer. No human dose, effect or safety profile has been established for MOTS-c as sold, so the certificate is the only checkable fact about a vial.
Who owns MOTS-c, and where it stands
| Originator | Discovered as a mitochondrial-derived peptide; the only drug candidate, CB4211, was CohBar's analogue. |
|---|---|
| Rights | No active rights holder or developer. CohBar suspended CB4211 and merged. |
| Development status | Development abandoned. CohBar stopped its analogue CB4211 after phase 1a/1b and merged; no other sponsor has a drug programme. |
| Clinical trials | 6 registered on ClinicalTrials.gov (lead sponsors: University of Athens, CohBar, Inc., Affiliated Hospital of Nantong University) |
| In the UK | Not a licensed medicine in the UK. Sold as a research chemical. |
Counts are from PubMed on 15 September 2026 using the queries recorded in our evidence file; "clinical trial" is PubMed's own publication-type index. This is a description of the published record, not medical advice and not an argument for or against use.

The Peptide Watch's position on MOTS-c
Not a licensed medicine in the UK. Sold as a research chemical. The Peptide Watch reads the certificates UK sellers publish and does not recommend anywhere to buy MOTS-c. Sellers on this page are listed by the date of their newest MOTS-c certificate and by nothing else. If you can verify a seller's testing, you can at least judge its evidence; if you cannot, you are taking the seller's word for what is in the vial. See how UK testing compares across every seller in the market statistics.
An honest note: a verifiable certificate proves a sample of a batch was tested, not that the specific vial you receive matches it, see what this can and can't tell you. The Peptide Watch sells no MOTS-c and links to no shop; this is research-use-only information, not medical or dosing advice.
