The short version
One supplier has four pages that could mention this compound. We read three on a stated date and never opened the fourth.
Here is what we found on 2026-10-01. The certificate index has an entry for MOTS-c. The front page now lists MOTS-c lot MTS-260414-A at 99.02 percent purity, tested June 2026. The store's MOTS-c page names the same lot and the same figure.
The list of reports from a second outside lab still has no line for MOTS-c. So the record today is one published certificate with a purity figure, and no second-lab report.
What can you check next? Open the store's MOTS-c page and match the lot code and certificate number against the certificates page.
Which pages do we read?
Four kinds of page:
- a certificate index
- a front page list of lots
- a list of reports from a second outside lab
- a product catalogue
We read the first three, not the catalogue.
The supplier also publishes three pages we name but leave alone: a walkthrough of one certificate, a company comparison built on five criteria, and a guide to checking a vendor before ordering. This site isn't any of those, so we don't audit or repeat them.
What does each page say?
One supplier, four of its pages, one compound. Three columns come from reading the page named. The fourth shows when we had it open. If nobody opened a page, it says so, and never says absent.

| Surface | What it prints about this compound | What it does not settle | Read on |
|---|---|---|---|
| certificate index | an entry, among the products with a published certificate | what any line inside that file reads, since nobody opened it here | 2026-09-01, certificate index |
| second laboratory register | absent | whether a report exists anywhere outside this register | 2026-09-01, second laboratory register |
| front-page lot list | lot MTS-260414-A, 99.02 percent HPLC purity, certificate COA-2026-5784, tested June 2026 | what the certificate file itself reads line by line, since we did not download it | 2026-10-01, front-page lot list |
| listed product catalogue | nothing read from this page | nothing at all, because nobody opened it | blank |
cells reading absent: 1
Rows are sorted by read date, earliest first, then by page name. A page we never read sorts last, because it can't take a place among pages we did open. The front page row was re-read on 2026-10-01 and updated; the other rows keep their September read dates.
Absent, blank and unread aren't the same
Absent means we opened the page on the date shown, and this name wasn't on it. A blank date means nobody opened that page. Neither one means a document doesn't exist, was refused, or was hidden.
Something missing from one page tells you about that page, nothing more.
The full rule is on what an empty column means here.
An honest empty column beats a filled one nobody could defend.
What does the certificate index show for MOTS-c?
It has an entry for this compound. Certificates are published on the certificates page, and MOTS-c is among the products with a published certificate.
The panel lines the index lists, in order:
- identity by a matching HPLC retention time
- a second identity check by LC-MS
- purity on HPLC against a release criterion of not less than 95.0 percent
- net peptide content, named as a line with no figure attached
- sterility and bacterial endotoxin
- heavy metals (arsenic, cadmium, chromium, mercury and lead), each reading Not Detected on the published batches
- a fentanyl screen
That's the panel.
Titreon Analytical runs the panels. The live page describes it as a third-party lab whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited.
One honest caveat. The index publishes and links its panels and some second-lab reports. We didn't download any for this compound, so we describe the set as published and linked, never as read. The full entry is on the index entry for this compound.
Is MOTS-c on the front page lot list?
Yes, as of 2026-10-01. The front page shows named lots, each with a lot code, a purity percentage and a certificate number. MOTS-c is there: lot MTS-260414-A, 99.02 percent by HPLC, certificate COA-2026-5784, tested June 2026 by Titreon Analytical.
When we first read the front page on 2026-09-07, MOTS-c was not on it. The list changed, so our answer changed.
That 99.02 percent belongs to this one lot. We don't stretch it to other lots or other products.
More on the printed lot list.
Does a second lab cover MOTS-c?
No. A second outside lab, Janoshik, supplies bacterial endotoxin reports for a few of the listed products. None covers this compound.
We don't name which compounds are covered. What matters here is that the list is short, and MOTS-c isn't on it.
The supplier says each report carries a unique key you can check at janoshik.com/verify. We didn't check one, and we don't link to that lab.
An empty line in a published list tells you about the list.
More on the second laboratory register.
Is anything printed on the vial?
No. The supplier says vials ship unlabelled on purpose, so nothing on the vial identifies a batch. To tie a delivered vial to its record, you contact support with your order number.
That's one supplier's practice, read on one page on one date. We don't assume anyone else does it.
Is MOTS-c approved for people?
No. This compound is research-grade material with no approved human label for any indication. An approved label, wherever one exists, covers one indication in one defined group. It never shows a compound is approved, safe or reviewed for anything else.
We say that even though MOTS-c has no approval, so nobody borrows an approval from somewhere else.
What does the research look like?
We count the research by study type rather than summarise it. Each row shows one study type, one example record, and what that type can't tell you.
The strongest evidence reporting an outcome is human observational. No human study in the set gave this compound to anyone, and the one registered study that will is still recruiting, with no results yet.
[ four columns, scroll the panel sideways for the full row ]
| Model type | Records at this model type | One representative record | What this model type cannot settle |
|---|---|---|---|
| review | 8 | PubMed 36761202 | A review reports what other records reported. It runs no experiment of its own and adds no outcome to the set. |
| animal | 5 | PubMed 25738459 | An animal model reports what happened in that species in that model. It settles nothing about a person. |
| in vitro | 2 | PubMed 29983246 | Work in cells reports what happened in cells. It settles nothing about an animal or a person. |
| human observational | 2 | PubMed 31214116 | Measuring what already circulates in people is not the same as giving them anything. An association settles no cause and no outcome. |
registered trial records: 9
completed administration trials reporting an outcome: 0
There's no direction column, on purpose. Read fast, a direction becomes a claim about a person, and we make none. Eight reviews, five animal records, two in vitro records and two human observational records make seventeen with a study type, plus nine registered trial records and no finished trial reporting an outcome.
One registered study that gives the compound to people is named here: NCT07505745, phase 2, recruiting, titled MOTS-c for Improving Insulin Sensitivity in Adults With Prediabetes and Overweight/Obesity. A registration reports no outcome, and a recruiting study has none yet.
We don't list the other registrations. They measure this compound in people rather than giving it, and mixing the two would blur the line this page draws.
The full picture is on what shape the record is in.
Why is there no seller table?
If you came here from a shopping search, you might expect a list of sellers. There isn't one. We didn't open any seller pages for this build, and a table of businesses nobody read is exactly the failure this site points out. We name, rank and link no seller, anywhere.
How do we read a page?
In short: a page is an address plus the date we opened it, either 2026-09-01 or 2026-09-07. Rows go in reading order, earliest first, never by preference. The two count lines under the table are generated from the rows at build time, not typed by hand.
We publish no instructions of any kind. Nothing here tells you to get, prepare, store or time anything.
The full method is on how a surface gets a row.
What does research use mean here?
This site checks published pages for a name, notes where it's missing, and dates every visit. It gives no description of the compound and makes no claim about its effect on anyone.
Material sold as research grade stays exactly that in our pages. None of this is medical advice, and none of it asks you to act.
Your questions, answered
Is a certificate of analysis published for MOTS-c?
Yes. The supplier's certificate index, read 2026-09-01, has an entry for this compound among the products with a published certificate. The index publishes and links its panels.
We didn't open the file for this compound, so we describe it as published and linked, never as read. We print no file path, because we never fetched one. More on the index entry for this compound, and what an empty column means here.
What lines does the supplier's certificate panel name?
Identity by a matching HPLC retention time, plus a second identity check by LC-MS. Purity on HPLC against a release criterion of not less than 95.0 percent. Net peptide content, as a line with no figure. Sterility. Bacterial endotoxin. Heavy metals (arsenic, cadmium, chromium, mercury and lead), each Not Detected on the published batches. A fentanyl screen.
The lab is Titreon Analytical, described on the live page as a third-party lab whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. These are the lines the certificate index lists. Nothing here comes from this compound's own file. More on the index entry for this compound.
What purity does the store print for MOTS-c?
99.02 percent by HPLC, for lot MTS-260414-A, on certificate COA-2026-5784. We read that on the store's MOTS-c page and its certificate index on 2026-10-01.
A percentage belongs to the lot it was measured on, so we tie this one to MTS-260414-A only. More on the printed lot list.
Is MOTS-c one of the lots printed on the supplier's front page?
Yes, as of 2026-10-01. The front page lists MOTS-c lot MTS-260414-A at 99.02 percent, tested June 2026 by Titreon Analytical.
On 2026-09-07 it was not listed. We changed this answer when the page changed. More on the printed lot list.
Does a second laboratory report cover MOTS-c?
No. A second outside lab, Janoshik, publishes bacterial endotoxin reports for a few listed products, and none covers this compound. The supplier says on its certificate index that each report carries a unique key you can check at janoshik.com/verify.
We didn't check one, and we don't link to that lab. It's a short list. More on the second laboratory register.
Why does this site not say what the MOTS-c peptide is?
Because describing a compound and reading the pages that carry its name are two different jobs, and we only do the second. You won't find composition, structure, class, mechanism or effects anywhere here, and we won't sneak them in now.
What we give you instead is which pages carry the name, which leave it out, and when we read each one. More on how a surface gets a row.
Does MOTS-c have an approved human label?
No. This compound is research-grade material with no approved human label for any indication. An approved label covers one indication in one defined group, and never shows a compound is approved, safe or reviewed for anything else.
The literature notes that no effective way of using this compound in the clinic has been developed (PubMed 36761202). A sports medicine review says rigorous human safety data are lacking for unapproved peptides (PubMed 41966639). We report both as discussion and a lack of data, not a conclusion. More on the record shape.
Has anyone given MOTS-c to people in a completed study?
Not in this set. No human study in the pack gave this compound to anyone. The strongest outcome evidence is observational: a cross-sectional blood study of 225 subjects (PubMed 31214116), and a physiology study in PCOS and healthy subjects measuring what was already circulating (PubMed 31066084).
One registered study that gives the compound is recruiting, NCT07505745, and has no results yet. A sports medicine review says rigorous human safety data are lacking for unapproved peptides (PubMed 41966639). We print no direction, benefit or outcome. More on the record shape.
Why is there no list of places to buy MOTS-c on this site?
Because we didn't open any seller pages for this build, and a table of businesses nobody read is exactly the failure this site points out. We read one supplier's own pages, and we assess, rank and list no seller. An honest empty column beats a directory built on brand recognition. More on how a surface gets a row.
Where can you buy MOTS-c?
We read one supplier's pages and list no sellers. That supplier, Peptara Labs, lists MOTS-c as research-grade material on its catalog. It isn't sold in pharmacies and has no approved human label.
How much does MOTS-c cost?
Peptara Labs, the supplier whose pages we read, lists MOTS-c at $185 per vial on its catalog. We print no price of our own. The lot it lists, MTS-260414-A, shows 99.02 percent purity on its certificate.
Can you buy MOTS-c in the USA?
Peptara Labs offers MOTS-c as research-grade material. It says it ships tracked worldwide in 5 to 10 business days, and in 2 to 3 days in the US on selected products. It isn't an approved human product and isn't sold in pharmacies.
More questions, about the supplier whose pages we read
What is Peptara Labs, on its own pages?
Peptara Labs describes itself as a source of research-grade compounds and educational material, not a medical provider. Its products and their certificates appear on its certificate index. We read its pages for one name and report what each one carries. We give no verdict on the company, because reading a company's pages and judging it are different jobs.
Who does Peptara Labs name as its testing laboratory?
It names Titreon Analytical. The live page calls it a third-party lab whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. We keep that qualifier with the name, exactly as the certificate index does, whole and never shortened.
Does Peptara Labs publish certificates of analysis?
Yes. Certificates are published on its certificate index. Whether we opened any single file is a separate question, covered on the index entry for this compound.
