Content equals the label
Purity (%) and content (the actual amount delivered) are not the same thing. We document both, so the amount on the label is the amount you receive — no quiet shortfalls.

Why buyers trust WUMO
Real content, documented — not guesswork
In this market, “99% pure” is often quoted while the amount actually delivered is far less. We keep purity and real content separate, and put both on paper — so MOTS-c 20mg Lyophilized Peptide Vial is backed by documents you can check.
Research peptide line — typical purity >99.3–99.4%, every batch MS-checked before release.
Every batch is verified
Identity and quality are confirmed by batch documentation — COA, plus HPLC / MS where applicable — before material is released.
Documented and traceable
Ingredient identity (INCI / CAS), specification sheet and SDS are available for review. Match the documents to your quoted batch before you commit.

Product Overview
MOTS-c is a mitochondrial-derived peptide commonly referenced as a 16-amino-acid sequence in scientific and research-sourcing contexts. This page presents a 20mg lyophilized vial fill specification for qualified B2B technical evaluation, documentation review, and project-level quotation discussion. It does not provide biological-effect discussion, dosing, end-user use instructions, clinical recommendations, or therapeutic claims.
For a controlled sourcing review, align the product name, CAS reference, sequence reference, salt or counterion form, vial fill specification, and required documents before comparing quotations. A catalogue purity figure or a vial label alone is not a complete technical specification.
Product identity reference
Molecular identity below reflects the standard scientific reference for MOTS-c. Confirm the salt or counterion form, and all batch-specific results, against the current specification sheet and Certificate of Analysis for your quoted batch.
| Field | Reference value |
|---|---|
| Product name | MOTS-c |
| Product format | Lyophilized peptide vial |
| Fill specification | 20mg per vial (assessed against a filling record; not an independent peptide-content assay) |
| CAS No. | 1627580-64-6 |
| Sequence reference | MRWQEMGYIFYPRKLR (16 amino acids) |
| Molecular formula | C101H152N28O22S2 (free-acid reference; state salt / counterion separately if applicable) |
| Molecular weight | ≈ 2174.62 Da (free-acid reference) |
| Appearance | White lyophilized powder |
| Salt / counterion | Confirm in current specification sheet and COA |
| Compliance | For laboratory research use only. Not for human or veterinary use. |
What buyers can request
For qualified MOTS-c projects, document review may include:
- Batch-specific Certificate of Analysis (COA)
- RP-HPLC purity documentation
- ESI-MS identity support
- SDS / MSDS for handling and shipment planning
- Product specification sheet
- Packaging, vial, label, and quote-unit clarification
- MOQ, lead-time, and private-label project discussion
Document availability, test scope, and batch linkage should be confirmed for the specific quotation rather than assumed from a previous lot.
Identity, purity, fill amount, and content are different checks
MOTS-c buyers should keep four questions separate so documents can be compared on a like-for-like basis.
| Check | What it answers | What it does not answer alone |
|---|---|---|
| ESI-MS | Whether the tested sample supports the intended molecular identity | Purity, vial fill amount, or actual peptide content |
| RP-HPLC | Chromatographic purity for the tested batch or sample | Identity, salt form, or actual vial content |
| Filling record | Whether the stated 20mg vial fill was recorded during filling | Independent assay of actual peptide content |
| Peptide-content assay | Actual content, when measured by a suitable validated method | Cannot be inferred from HPLC purity alone |
Bulk powder, vial fill, and private-label scope
The supplied 20mg format is a vial-fill specification. Buyers who require a different project path should state it at inquiry stage.
| Project path | Key details to state in the RFQ |
|---|---|
| Standard 20mg vial | Required vial count, document package, destination, and timing |
| Alternative fill specification | Target fill amount, vial and stopper format, packaging, and required documentation |
| Bulk material | Target quantity, salt / counterion requirement, purity threshold, and quote unit |
| Private label | Vial count, label / box requirements, document scope, destination, and project timeline |
MOQ and lead time depend on current batch status, requested documentation, packaging scope, and project configuration. They should be confirmed in writing for the specific inquiry.
Quality and documentation boundary
A supplied 20mg vial test report on a tested sample records ESI-MS identity confirmation, a 20mg/vial label claim checked against a filling record, and 99.79% RP-HPLC purity. These results apply to that tested batch or sample only and should not be presented as a fixed guarantee for every future batch.
For current sourcing decisions, request the documents that apply to the quoted batch and verify that the batch identifier is consistent across the COA, HPLC report, identity record, specification sheet, and shipment or packaging documentation.
Compliance note
This page is for qualified B2B technical evaluation and business-side documentation review only. MOTS-c is offered for laboratory research use only, not for human or veterinary use. Buyers remain responsible for the intended use, importation, labeling, downstream compliance, and destination-market requirements.
Frequently asked questions
What does the 20mg vial specification mean?
It refers to the stated fill quantity for one lyophilized peptide vial in a B2B project. It is a packaging specification, not a dosing or use instruction.
What documents can buyers request for a MOTS-c 20mg vial project?
For qualified projects, buyers may request batch-specific COA, RP-HPLC purity information, ESI-MS identity support, SDS/MSDS, and a product specification sheet, subject to batch and project scope.
Does RP-HPLC purity prove the 20mg fill amount?
No. RP-HPLC reports chromatographic purity for the tested sample. Fill amount is a separate packaging or filling-record question, and actual peptide content requires an appropriate content-assay method where that confirmation is required.
Does ESI-MS prove product purity?
No. ESI-MS supports molecular identity. Purity should be evaluated from the applicable chromatographic method and batch documentation.
What should buyers confirm before comparing MOTS-c quotations?
Confirm the product name, CAS reference, sequence reference, salt or counterion form, vial fill or bulk format, required documents, MOQ basis, lead-time basis, packaging scope, and quote unit before comparing suppliers.
Can the page support bulk powder or a different vial fill?
Project options may be discussed based on the requested format, quantity, documentation scope, and packaging requirements. State the target specification in the inquiry so the quotation is prepared on the right basis.
Can WUMO discuss neutral-label or private-label vial projects?
Yes. For qualified B2B projects, provide the target vial count, fill specification, label or box scope, document requirements, destination, and timeline for feasibility review.
Is MOTS-c offered for consumer, medical, or veterinary use?
No. This product path is for laboratory research use only and is not intended for human or veterinary use.
