MOTS-c is one defined 16-amino-acid sequence, not a blend or a category name like Glow or Klow, so what should be in the vial is not in question. What varies between sellers is whether it was tested and what the test covered. The product page lists the full specification. Peptryn does not give dosing or use guidance for MOTS-c, because no dose has been established.
MOTS-c price: what to compare
At the listed price, the 40 mg vial costs $3.50 per mg. Price per mg compares two sellers only when the products match. Line up these before you compare:
- Size. Sellers list 10 mg and 40 mg vials. Peptryn lists the 40 mg size only, so a 10 mg listing is a different purchase.
- Lot and lab. A price with no lot-matched report gives you a number and no verification.
- What the report covers. Purity, identity, endotoxin and quantity are separate results.
- What the seller sells. A vial of lab material is not the same product as a clinic or pharmacy service.
What the MOTS-c certificate shows and leaves out
| Question | What the certificate shows |
|---|---|
| Method | HPLC-UV-MS |
| Purity | 99.78% |
| Endotoxin | Negative |
| Where the records sit | The purity and identity record is on MZ Biolabs’ own site and linked by a QR code on the certificate. The endotoxin report is a PDF shown on the certificate page |
| Quantity and mass | The lab report prints a measured quantity per vial (45.41 mg against the 40 mg label) and the expected and measured monoisotopic mass (2,173.11 Da and 2,173.16 Da) |
Our September 2026 data report read the lab’s report for this lot and listed the measured quantity. The lab reported 45.41 mg of MOTS-c against a 40 mg label, a difference of +13.5%. The result comes from one lot, from one laboratory, without a stated assay uncertainty. The report lists open questions, including whether a quantity figure is net peptide content or the gross contents of the vial.
Five checks for any MOTS-c vial
- Does the lot match? Compare the lot on your vial with the lot on the report, and check that the analysis date fits the lot date.
- Is the report on the lab’s own site? A link or QR code to the lab’s record beats a PDF that lives only on the seller’s server. Our third-party tested peptides guide sorts these claims into five levels.
- Does the report confirm identity? The expected mass is 2,174.6 Da. MOTS-c has two methionines, and each oxidized one adds 16 Da, so a second peak near 2,190.6 Da shows oxidation. Our MOTS-c guide explains why this matters for this peptide.
- Which tests are listed? Identity, purity, endotoxin and quantity are different tests. Each one missing is a gap, and our certificate guide shows how to read them.
- How does the seller describe use? A research listing promises no fat loss, longevity or anti-aging results and gives no dosing schedule. The research on MOTS-c comes mainly from cells and mice, and no completed controlled human trial supports those claims. See are peptides legal? for background.
MOTS-c and SS-31 are different products
MOTS-c and SS-31 are unrelated compounds that often appear in the same searches. MOTS-c is a natural 16-residue peptide encoded in mitochondrial DNA. SS-31 is a synthetic peptide that binds cardiolipin, and its approved form, elamipretide (Forzinity), is a drug for Barth syndrome. A research vial of either is not a drug. See the SS-31 buying page for that listing.
Why MOTS-c search results look so mixed
A search for “mots-c peptide for sale” on October 12, 2026 returned research-peptide shops, drug-information pages, a pharmacy page and clinic programs that offer MOTS-c as a physician-guided service. These are different things with different rules.
Peptryn’s listing is a laboratory research material. It is not a clinic program, a supplement or a drug, and Peptryn does not offer it for human use.

Is Peptryn’s MOTS-c third-party tested?
Yes. Lot 2026-07-07 was tested by MZ Biolabs, which reports 99.78% HPLC purity and a negative endotoxin result. The purity and identity record is on the lab’s own site, and Peptryn is the client that ordered the test.
Does Peptryn sell MOTS-c in 10 mg?
