Know Everything About MOTS-c Before You Buy
MOTS-c has a big following in metabolic research.
MOTS-c Specifications at a Glance
It is a 16-amino-acid peptide coded by mitochondrial DNA. Lee and colleagues first described it in Cell Metabolism in 2015. Kylo lists these specs for its synthetic, solid-phase-made material:
- Sequence: Met-Arg-Trp-Gln-Glu-Met-Gly-Tyr-Ile-Phe-Tyr-Pro-Arg-Lys-Leu-Arg
- Formula: C101H152N28O22S2
- Molecular weight: 2174.64 g/mol
- CAS number: 1627580-64-6
- Form: Lyophilized powder
MOTS-c Vial Sizes
You’ll mostly see 5mg, 10mg, and 20mg vials, and 40mg vials are showing up more often. Kylo offers 10mg and 40mg. A bigger vial usually costs less per mg, but the testing behind it determines the quality. Here’s an insider tip: if you’re running a longer study, keep all of it on one lot. One lot means one COA covers every experiment.
MOTS-c Physical Forms
Research MOTS-c comes as a lyophilized “cake,” which is a freeze-dried puck of powder at the bottom of the vial. The label should list the compound, amount, lot number, and research-use status. Dry powder lasts much longer than liquid.
MOTS-c Pricing: What Does It Actually Cost?
At Kylo, a 10mg vial runs $64.95 and a 40mg vial runs $169.95. Two vials save 5% and three save 10%. Shipping is free over $150.
MOTS-c Storage and Handling
Kylo lists −20 °C for the sealed powder, −80 °C for long-term storage, and 2 to 8 °C after reconstitution. Keep it dark and dry. It matters for MOTS-c in particular because methionine sits at positions 1 and 6 and tryptophan at position 3. Those residues oxidize easily, a bit like a cut apple turning brown.
Shipping and Transit Considerations
Kylo ships from U.S. warehouses in Austin, TX, and Long Beach, CA, and adds thermal protection when needed. When the box lands, check that the vial is intact and the cake looks dry. Then match the lot number on the label to its COA.
What Researchers Actually Receive When They Order MOTS-c Peptide From Kylo
The MOTS-c Product
You get a sealed vial of lyophilized MOTS-c, 10mg or 40mg, with the lot number printed on the label. The label also shows the compound name, the net quantity, and research-use status. The lot ID is your key to the COA. Snap a photo of the label the day it arrives; it makes record-keeping painless later.
The Documentation That Should Come With It
A proper COA lists the lot number, HPLC purity result, identity result, test date, testing lab, and analytical method. Some also report net peptide content. At Kylo, the COA lives online and matches the lot ID printed on your vial.
Kylo’s Public COA Library
Kylo publishes its certificates in a public COA library on its website. You can check a lot’s results before you order and again after delivery. Save the PDF with your research records so the proof stays with the data.
From Product Page to Research Record
Think of it as a chain where each link hands off to the next:
MOTS-c listing → Order → Lot → Vial → COA → Testing documentation → Research records
How Kylo Verifies MOTS-c: Looking Beyond a Purity Number
A purity number is a good start, but it answers only one question. Here’s what else you need to verify to know the full picture.
HPLC Purity Testing
Kylo targets ≥99% purity by HPLC on every lot. HPLC shows how much of the sample is the main peptide versus other stuff. It tells you nothing about how much powder is in the vial, and it doesn’t confirm which peptide you have.
LC-MS Identity Documentation
LC-MS weighs the molecule to confirm identity. For MOTS-c, the COA may list a value around 1088 or 726. Those are the same peptide carrying two or three charges, which is normal. A peak about 16 Da heavier points to oxidation.
Independent Laboratory References
Kylo names Vanguard Laboratory, Janoshik Analytical, Optiq Health Labs, and Freedom Diagnostics as its testing partners. These are independent labs, ISO/IEC 17025 accredited. A named outside lab lets you trace who produced the result. You can then check that lab’s report details against what the supplier shows.
Why Multiple Pieces of Documentation Matter
Purity, identity, lab, and test date only mean something when they all attach to the same lot. Read together, they tell you what’s in your vial, who tested it, and when.
How to Tell Whether a MOTS-c Supplier Is Legitimate
Start With the Product Page
Check the compound, quantity, form, purity spec, lot info, research-use status, and storage details. If the listing is thin on specs, that’s your first clue. A detailed listing should read like a data sheet.
Follow the Documentation Trail
Can you actually open the COA? Does it match the lot you’d receive, and does it name the lab and the method? Make sure you can download it and keep it, too.
Check Whether the Supplier’s Claims Match Its Documents
Compare the supplier’s purity claim to the COA, and the label quantity to the paperwork. The lot number, test date, and identity data should all line up. Small mismatches can clear up with a quick email to support.
Look Beyond the COA
Look for a real business name, a physical address, a phone number, and clear terms. Check the shipping and refund policies and the research-use requirements. A research supplier also avoids health or therapeutic claims.
MOTS-c Supplier Red Flags: 10 Things That Should Make You Pause
- No clear specs. Without the sequence and weight, you can’t check the COA against anything.
- No COA at all. Then there’s no evidence the lot was ever tested.
- A generic COA with no lot number. It could belong to any batch.
- A purity figure with no method. “99%” claim is not evidence unless an HPLC test backs it.
- An unnamed lab. A result with no lab name behind it can’t be traced.
- A quantity you can’t verify. The fill should match the label and the paperwork.
- Contradictory info. Different sizes or purity numbers on different pages point to sloppy records.
- Fuzzy research-use labeling. Legit research suppliers abide by it.
- Medical or therapeutic claims. Research-use-only material shouldn’t come with health promises.
- No real contact info. If something’s off, you need prompt support to take accountability.
Reading a MOTS-c COA Without Being a Laboratory Expert
You don’t need a chemistry degree for this. Here’s how to read a COA in about two minutes.
Identity vs. Purity
Identity answers “is this MOTS-c?” Purity answers “how clean is it?” A vial can pass one and fail the other, so you want both results.
HPLC Results
HPLC gives a percentage and usually a chromatogram, a chart with one tall main peak. It shows cleanliness. It says nothing about weight or identity.
LC-MS / Mass Spectrometry
This is the identity check. Match the reported mass to about 2174, or to the charged values around 1088 and 726.
Net Peptide Content
The label claim says (10mg), and the net content measurement verifies it, so you know the vial is selling a quantity it actually claims.
Testing Date and Lot Number
The lot number connects the COA to your vial. The date tells you how recent the test is. Match both before you file it.
Independent Laboratory vs. Supplier-Generated Documentation
A named third-party lab adds traceability, while in-house data depends on the supplier’s own process. Either way, judge the full report, including its methods, dates, and lot links.
What Happens After You Order MOTS-c From Kylo?
Order Confirmation
Your confirmation lists the product, vial size, quantity, and shipping details. At checkout, Kylo asks you to confirm you’re 21+ and buying for in vitro research.
Fulfillment
We allocate stock and assign a lot. We label the vial with that lot ID, pack it, and create shipping documentation.
Domestic Shipping
Weekday orders placed before 2 PM PST leave the same day, and the rest ship within 24 hours. Tracking hits your inbox within about four hours. USPS Priority usually takes 2 to 4 business days.
Arrival Inspection
Check that you got the right compound and vial size, with the seal intact. The lot number should be visible and should match a COA in the library. Look at the packaging condition too.
Documentation After Delivery
Keep the order confirmation, invoice, COA, lot number, a photo of the label, and the shipping record. Together, that’s your audit trail.
MOTS-c Price Comparison: Don’t Compare Vials Alone
A cheap-looking vial can cost more per mg. Start with one simple formula.
Cost per mg = Total product price ÷ Peptide quantity (mg)
| Kylo MOTS-c Option | Total Price | Price per mg |
| 1 × 10mg | $64.95 | $6.50 |
| 1 × 40mg | $169.95 | $4.25 |
| 3 × 10mg (10% off) | $175.37 | $5.85 |
| 3 × 40mg (10% off) | $458.87 | $3.82 |
| 10mg, member price (50% off) | $32.48 | $3.25 |
| 40mg, member price (50% off) | $84.98 | $2.12 |
Quick example: three 10mg vials give you 30mg for $175.37. One 40mg vial gives you 10mg more for $5.42 less.
Shipping changes the math too. Kylo ships free over $150, so a single 40mg vial qualifies, and a single 10mg vial doesn’t. Membership is a one-time $497 for 50% off for life.
Now for a myth worth busting. Some buyer guides call anything under $5/mg a warning sign, and others draw the line at $2/mg. By those rules, Kylo’s 40mg vial and its member pricing would look “suspicious,” even though it’s a well-tested product. Price per mg reflects vial size and pricing model. The COA is what confirms quality.
Kylo Peptides MOTS-c: What Stands Out for Research Buyers
U.S.-Based Research Supply
Kylo Peptides is a U.S.-based supplier run by Kylo Labs LLC. Orders ship from domestic warehouses in Texas and California.
Research-Only Positioning
Kylo labels MOTS-c “For Research Use Only · Not for human or veterinary use.” In July 2026, an FDA advisory committee voted 7 to 5, with two abstentions, to recommend MOTS-c for the 503A compounding list. The vote is non-binding, and MOTS-c still has no FDA approval.
Lot-Specific COA Documentation
Every lot gets its own certificate, published in Kylo’s public COA library. The lot ID on your vial pulls up the matching report.
Analytical Verification
Each lot targets ≥99% HPLC purity and includes LC-MS identity testing. Testing runs through Vanguard Laboratory, Janoshik Analytical, and Freedom Diagnostics, all ISO/IEC 17025 labs.
Documentation-First Purchasing
Product → Lot → Testing → COA → Research record.
Kylo’s setup is built so each step points to the next. Add in shipping protection and a 30-day money-back guarantee, and you get a clear, checkable supply trail from listing to lab notebook.
MOTS-c vs. Humanin: Why Compound Identity Still Matters
Both are mitochondrial-derived peptides, and people sometimes lump them together. Here’s how they differ.
Different Peptide Sequences
MOTS-c has 16 amino acids and comes from the 12S rRNA gene. Humanin has 24 amino acids and comes from the 16S rRNA gene. They’re completely different molecules.
Different Research Histories
Humanin was reported in 2001, and MOTS-c followed in 2015. Each has its own literature and study models.
Different Product Specifications
Different sequences mean different weights, formulas, and COA targets. A humanin COA can’t vouch for a MOTS-c vial.
Why Mitochondrial-Derived Peptides Should Not Be Treated as Interchangeable
Swapping one for the other adds an uncontrolled variable to your research. Always match the compound name, sequence, and mass on the COA. If a listing only says “mitochondrial peptide,” ask which one.
Questions to Ask Before Choosing a MOTS-c Supplier
Run through this list before you check out.
- Do I know exactly what quantity I’m buying?
- Can I verify the current lot?
- Is the COA tied to that lot?
- Can I identify the testing lab?
- Does the COA cover both purity and identity?
- Does the product page match the COA?
- Is storage information clear?
- Are shipping details spelled out?
- Is the research-use status stated plainly?
- Can I work out the true price per mg?
- Is there enough documentation for my research records?
- What’s still missing before I place the order?
Any “no” or “not sure” is a cue to email support before you buy. A solid supplier answers fast and points you straight to the document you need.
Final Thoughts: Buying MOTS-c Is About Verification, Not Just Availability
Finding MOTS-c for sale is the easy part. The real work is checking what sits behind the product name and price tag. Look at quantity and price together, and make sure the COA points to your actual lot. Name the testing method and lab, and make storage, shipping, and research-use terms easy to find.
Kylo’s MOTS-c comes with U.S.-based supply, lot-matched COAs in a public library, a ≥99% HPLC target, and LC-MS identity testing so that you can check every link yourself. Give the documents ten minutes before you order. The habit protects your data better than any bargain.
