Where to Buy MOTS-C Peptide for Research in 2026: My Comparison of 3 Suppliers
By Roger Davis, Peptide Researcher and Supplier Analyst, 4 Years. Reviewed by Clark Martinez, Editor. Last updated October 14, 2026
Where can you buy MOTS-c peptide from a supplier that actually shows its receipts? I mean clear specs and batch documents you can check yourself. When I started researching, I wanted to look beyond product availability and advertised purity. Pretty much every vendor claims their peptide product is “99%+ pure.” Only a few back that up with documentation from independent lab checks.
To find one of those few, I lined up three suppliers: Kylo Peptides, American Peptides, and True Research Labs, and compared them on product specs, COA access, analytical testing, batch traceability, pricing, and shipping terms. This is a detailed account of what I found with each.

What I Looked for When Comparing MOTS-c Research Suppliers
I looked for identity, purity, fill accuracy, endotoxin, and lab verification.
I Started With Product Availability and Specifications
First, I checked that each supplier had a dedicated MOTS-c product listing. Then I checked the basics: vial size, form, identifiers like the CAS number and sequence, and whether the page showed the product as in stock.
I Prioritized Verifiable Testing Documentation
Next came the paperwork. I wanted a batch-specific COA (Certificate of Analysis) with HPLC and mass-spec results, plus the lab name, report date, and lot number. In Peptigrity’s public log of 581 independent MOTS-c vial tests, 95% cleared 99% purity, yet only 27% could be confirmed on the testing lab’s own portal.
I Compared Pricing and Ordering Transparency
Then I checked listed prices, vial sizes, and free-shipping thresholds. Price and purity were my starting point. The batch documents closed the deal.
1. Kylo Peptides: My First Stop for MOTS-c Research
Kylo Peptides was my first stop. Here’s what its MOTS-c listing shows and how the paperwork held up.
What I Found in the Kylo Peptides Catalog
Kylo lists MOTS-c in 10 mg and 40 mg vials. It’s described as a 16-amino-acid mitochondrial-derived peptide, supplied as a lyophilized (freeze-dried) powder with an acetate counter-ion. That puts it in a different class from SARMs, which all act on the androgen receptor.
The spec sheet specifies the CAS 1627580-64-6, formula C101H152N28O22S2, molecular weight 2174.64 g/mol, and the full sequence. Storage is listed at -20 °C for the powder and 2 to 8 °C after reconstitution.
The 10 mg vial is $64.95, or $32.48 with a Kylo membership. It’s marked in stock and labeled research use only, not for human or veterinary use.
How I Evaluated Kylo’s Testing and COA Access
Kylo’s spec table lists purity at ?98% by HPLC-UV, with LC-MS mass confirmation against the reference molecular weight. HPLC shows how clean the sample is, and LC-MS confirms it’s the right molecule.
The lot-matched MOTS-c COA sits in Kylo’s public COA library, and the lot ID is printed on the vial, so you can pair the two. Every lot is tested by an independent laboratory.
What Stood Out to Me About Kylo
Getting from the listing to the COA library takes one click, which I liked. The refund terms stood out too. Kylo’s 30-day money-back guarantee covers wrong items, broken vials, and a COA mismatch. Orders leave its US warehouse within 24 hours on business days, and US shipping is free over $150. A cold pack is a separate $9.99 add-on, so factor that into the final cost.
After reviewing Kylo’s product information, I applied the same criteria to American Peptides to compare its documentation and purchasing information.
2. American Peptides: How Its MOTS-c Listing Compared
American Peptides is one of the top contenders in the peptide market right now, so I took a close look at its MOTS-c listing.
What I Found on the American Peptides Product Page
The MOTS-c listing offers 10 mg and 40 mg options. The 10 mg vial is $100, and a subscription option runs $85 per delivery. It’s sold as a lyophilized powder made by solid-phase peptide synthesis (SPPS), and it’s clearly marked research use only.
The spec block is easy to scan: sequence, formula, CAS number, and storage at -20 °C away from light and moisture. The listing also suggests buying a $30 reconstitution solution alongside it.
I Checked the COA and Independent Testing Claims
The vendor claims 99.9% purity in its highlights and “?99% (HPLC Verified)” in the specs, naming HPLC and mass spectrometry as methods. Two lot-coded COAs are linked to verify it: MOTS10-0803 for 10 mg and MOTS40-0803 for 40 mg, plus a safety data sheet (SDS). The p testing lab is not named, so I’d open the PDF and confirm it, besides the test date, and other results.
My Assessment of American Peptides
American Peptides made its batch documents easy to reach: one click from the listing, same as Kylo. Kylo’s lot ID on the vial gives it a small edge, though. Pricing sits at the higher end, at $10 per mg for the 10 mg vial. Free shipping starts over $300, and sales are final, with replacements for damaged or incorrect items reported within 72 hours. Before ordering, I’d confirm the COA lot matches the vial I’d receive.
3. True Research Labs: Reviewing Its MOTS-c Testing Standards
True Research Labs puts testing front and center on its MOTS-c listing. Here’s what I found.
What I Found in the True Research Labs Catalog
True Research Labs lists MOTS-c in 10 mg and 40 mg options. One vial is $59, two are $108, and three are $153, so bundles save up to 15%. It’s described as a high-purity lyophilized research peptide for laboratory research only. The listing is light on the details, though. I didn’t see a sequence, CAS number, or storage temperature listed.
How I Reviewed True Research Labs’ COA Information
The vendor claims ?99% purity backed by independent third-party HPLC and mass-spec analysis. It also describes batch-level endotoxin screening with the LAL (Limulus Amebocyte Lysate) method, which checks for bacterial toxins. That’s a rarer claim: in Peptigrity’s database, only about one in four MOTS-c tests reported endotoxin at all. The listing posts both a Purity COA and an Endotoxin COA.
What I Noticed About Its Documentation
For a paper-trail person like me, one gap stood out. The COA titles appear on the listing, but I couldn’t open them from there, and I didn’t see a lot of numbers or test dates. The lab isn’t named either. I’d email support for the lot-matched PDFs before ordering, which is easy enough. Good to know: True Research Labs doesn’t accept returns or issue refunds. Free shipping and a free bottle of bacteriostatic water kick in at $250.
Kylo vs. American Peptides vs. True Research Labs: My Comparison
How the Three MOTS-c Suppliers Compare on Quality Documentation
| Evaluation factor | Kylo Peptides | American Peptides | True Research Labs |
| Dedicated MOTS-c listing | Yes (10 mg, 40 mg) | Yes (10 mg, 40 mg) | Yes (10 mg, 40 mg) |
| Published purity | ?98% (HPLC) | 99.9% / ?99% (HPLC) | ?99% |

| Endotoxin | Listed as absent from the vial | Banner claim, no result on page | LAL screening, Endotoxin COA named |
| 10 mg price | $64.95($32.48 member) | 100(85 subscription) | 59(51 each in a 3-pack) |
| Free US shipping | Over $150 | Over $300 | Over $250 |
| Refunds | 30-day money-back | Final sale, damage replaced | No returns or refunds |
Which Supplier Made Verification Easiest?
Kylo and American Peptides both put the COA one click from the product listing. Kylo prints the lot ID on the vial, so matching paper to the product is even simpler. True Research Labs may ask for a support email.
How I Compared Price and Product Quantity
For 10 mg vials, Kylo works out to $6.50 per mg ($3.25 for members only), American Peptides to $10.00, and True Research Labs to $5.90, or $5.10 in a 3-pack. Shipping changes the final cost, so check where your cart lands against each threshold. For me, price is the tiebreaker once the paperwork checks out.
How I Verified MOTS-c Purity and Identity Claims
A COA is only useful if you know how to read it. Here’s what I checked on each report.
What I Looked for in HPLC Results
HPLC shows what share of the sample is the target peptide. I checked the purity figure, the method, and that the sample and lot IDs matched.
Why I Checked Mass-Spectrometry Results
Mass spec confirms identity, meaning the molecule weighs what MOTS-c should, about 2,174 g/mol. I made sure each report named the same compound as the listing.
How I Checked Batch-Specific COAs
Last, I matched the COA lot number to the product’s lot. Then I checked the lab name, test date, and results. I flagged anything missing, outdated, or marked pending in my notes.
What I Would Check Before Selecting a MOTS-c Supplier
Here’s the quick checklist I’d run before picking a MOTS-c supplier.
- I can find a current MOTS-c product listing.
- The vial size and form are clear.
- I can open the COA for the exact batch.
- Purity and identity testing are both documented.
- The testing lab and methods are named.
- Pricing, shipping, and refund terms are spelled out.
- Research-use-only labeling is clear.
If a box stays unticked, I’d message support first. Most suppliers will happily send what’s missing. In the end, I’d decide on the documents for the specific batch in my cart.
Frequently Asked Questions
Where can I buy MOTS-c peptides for research?
Kylo Peptides, American Peptides, and True Research Labs all list MOTS-c for research in 10 mg and 40 mg vials. Prices for 10 mg run from $59 to $100. Check each current listing and batch COA before you order, since stock and lots change.
Which MOTS-c supplier provides a Certificate of Analysis?
Kylo publishes lot-matched COAs in its online library, and American Peptides links lot-coded COAs on its product page. True Research Labs names purity and endotoxin COAs on its listing. Whichever you pick, match the COA lot to your vial.
How do I compare MOTS-c peptide prices?
Compare the same vial size, then work out price per mg. Add shipping, since free-shipping thresholds run from $150 to $300 across these three. Then weigh the documentation, because a well-documented vial is the better value.
Is a 99% purity claim enough when choosing MOTS-c?
No. About 95% of independently tested MOTS-c vials in Peptigrity’s database already hit 99%. Identity testing, fill accuracy, endotoxin data, and a lot-matched COA tell you much more.
Is MOTS-c approved for human use?
No. MOTS-c isn’t FDA-approved for human use, and the FDA’s compounding safety page flags open questions. A July 2026 advisory committee vote recommended it for compounding, but that vote isn’t binding. Research-use-only labeling marks it as a lab material.
Final Thoughts: Choosing a MOTS-c Research Supplier
All three suppliers list MOTS-c for laboratory research in 10 mg and 40 mg vials, at $59 to 100 for 10mg (5.90 to $10.00 per mg). With Kylo membership, the price drops to $3.25 per mg. What separates them is documentation and terms, not availability:
- Kylo Peptides has the lowest member price, a full spec sheet (CAS, formula, molecular weight, sequence), dispatch within 24 hours, and a 30-day guarantee that covers COA mismatches.
- American Peptides links lot-coded certificates (MOTS10-0803 and MOTS40-0803) from the listing, at the highest price per mg and with sales final.
- True Research Labs has the lowest list price and bundle savings, but its certificates couldn’t be opened from the listing and it doesn’t accept returns.
Whichever you choose, check three things before you order: a certificate for the exact lot and vial size, an identity result near 2,174.6 g/mol, and the lab and test date. MOTS-c is sold as a laboratory reference material only and is not approved for human use.
Disclaimer: MOTS-c is sold as a laboratory reference material. It isn’t approved by the FDA for human use, and nothing here is medical advice.
