Verifying MOTS-c means matching the listed SKU, the nominal vial size and pack quantity, and the certificate of analysis (COA) that names that same SKU and batch. The compound name alone is not enough when several sizes exist. Catalog milligram values are nominal; recorded identity, fill, and purity apply only to the tested batch.
Listed SKUs, vial size, and pack quantity
The public MOTS-c product listing records CAS number 1627580-64-6, molecular formula C100H165N27O26S, and molecular weight 2174.6. Four public SKUs are shown. That catalog covers public listed variants only and is not a claim that the list is exhaustive.
| SKU code | Nominal size per vial | Vials per pack |
|---|---|---|
| MS10 | 10 mg | 10 |
| MS15 | 15 mg | 10 |
| MS20 | 20 mg | 10 |
| MS40 | 40 mg | 10 |
Editorial guidance on per-vial size versus pack quantity treats per-vial size, vials per pack, and pack price as three separate fields. A description such as "10 mg × 10 vials" means ten vials with a nominal size of 10 mg each; it is not a single vial containing 100 mg. The pack sum is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report.
Before relying on a quotation, match the exact product and SKU, check the per-vial size and unit, check vials per pack, set the number of packs, and review matching batch records. If documentation uses a different packaging description, ask support to reconcile it before relying on the calculation.
Published COA results for named batches
A SKU identifies a listed variant; a batch number identifies a batch record. Use both when following site guidance to find a COA by SKU and batch. A MOTS-c report for one size is not evidence for another size. An older published batch is not evidence of the batch that will be shipped next. A missing public result is neither a failed test nor a passed test.
Published examples are MS10 batch V85K3SOY13M5 (certificate QC-2026-NVHRRYGETR, analyte MOTS-c MS10), MS15 batch REEAPI409ER4 (certificate QC-2026-FCZ2PP4QH2, analyte MOTS-c MS15), and MS20 batch W632DJJR03D2 (certificate QC-2026-ERUM25PS8K, analyte MOTS-c MS20). Each of those three records names laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group) and test date 2026-08-12. Provider verification links were not independently fetched. The recorded results are not evidence of clinical suitability or of every batch.
On all three records the specifications read: appearance, White or almost white loose powder (Visual); mass spectrum, 2174.6 +/- 1.0 Da (MS); purity, NLT 98.0 % (HPLC); peptide content, NLT 90.0 % (HPLC); water content, NMT 8.0 % (Karl Fischer); bacterial endotoxins, NMT 10 EU/mg (LAL (gel-clot)). Gravimetric actual-fill specifications are 10 mg, 15 mg, and 20 mg respectively. Each item in the table was recorded as Pass. No MS40 COA is among these published records.
| Item (method) | MS10 V85K3SOY13M5 | MS15 REEAPI409ER4 | MS20 W632DJJR03D2 |
|---|---|---|---|
| Appearance (Visual) | White loose powder | White loose powder | White loose powder |
| Mass spectrum (MS) | 2173.9 Da | 2174.2 Da | 2174.0 Da |
| Purity (HPLC) | 98.8 % | 99.6 % | 99.5 % |
| Peptide content (HPLC) | 92.3 % | 91.5 % | 91.6 % |
| Actual fill (Gravimetric) | 11.43 mg | 16.49 mg | 23.91 mg |
| Water content (Karl Fischer) | 5.8 % | 5.4 % | 3.7 % |
| Bacterial endotoxins (LAL (gel-clot)) | <3 EU/mg | <3 EU/mg | <3 EU/mg |
Identity, purity, weight, and endotoxin summary fields on those pages match the mass-spectrum, purity, actual-fill, and endotoxin rows.
How to verify the certificate
Site guidance on how to verify a CertiPeptide COA starts by matching product name, SKU, and batch number. Open the original report and compare certificate number and test date with the summary. Then use that report's verification link. A verification page may require a provider account; seeing a link alone does not prove the report is currently valid.
- Read the product and SKU from the product page or order documentation.
- Find the batch. If the allocated batch is not stated, ask support to confirm it.
- Open the batch page and check certificate number, sample identity, test date, and listed laboratory.
- Open the original report and compare values and units with the summary.
- Follow the report-specific verification link. If login is required or the record cannot be confirmed, resolve that before treating verification as complete.
Do not substitute a report for a different size. Send support the SKU, batch number, and the specific difference. A screenshot helps comparison; the original document and provider record are stronger evidence. A published report does not mean every order receives that batch.
Checklist:
- Confirm product name MOTS-c and SKU MS10, MS15, MS20, or MS40.
- Keep nominal mg per vial and 10 vials per pack as separate fields; do not treat the pack sum as measured fill.
- Match batch and certificate to that SKU only.
- Copy each analyte, method, unit, qualifier, and determination exactly, including "<3 EU/mg" and "2174.6 +/- 1.0 Da".
- Treat 11.43 mg, 16.49 mg, and 23.91 mg as named-batch gravimetric fills, not as new catalog sizes.
- Do not use an MS10, MS15, or MS20 report as evidence for another SKU, including MS40.
- If a public report is missing, ask support for the exact SKU and batch.
Frequently Asked Questions
Can an MS10 COA stand in for MS15, MS20, or MS40?
No. A MOTS-c report for one listed size is not evidence for another size. Match product name, SKU, and batch number together.
Does a published MOTS-c report mean every order receives that batch?
No. Confirm the batch allocated to the order separately. An older published batch is not evidence of the batch that will be shipped next.
What pack layout do the listed MOTS-c SKUs use?
The public listing shows MS10, MS15, MS20, and MS40 with 10 vials per pack and nominal per-vial sizes of 10 mg, 15 mg, 20 mg, and 40 mg. Those milligram values are catalog sizes, not measured fills.
What if no public COA is listed for a MOTS-c SKU?
A missing public result is not a failed test and is not a passed test. Ask support for the exact SKU and batch rather than substituting a different record. Published MOTS-c COAs described here cover MS10, MS15, and MS20; no MS40 COA is included.
Which laboratory and test date appear on the published MOTS-c COAs described here?
Each of the three published records names Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group) and test date 2026-08-12. Provider verification links were not independently fetched.
