To verify Kisspeptin, match the exact SKU, the per-vial milligram size, and the vials-per-pack count as three separate fields, then open the published COA for that SKU’s named batch. The product name alone is not enough when more than one size or lot is listed.
Match the SKU, vial size, and pack quantity
The public Kisspeptin product listing records CAS number 374675-21-5, molecular formula C63H83N17O14, and molecular weight 1302.5. Two public listed variants appear: KS5 (nominal 5 mg per vial, 10 vials per pack) and KS10 (nominal 10 mg per vial, 10 vials per pack). That table is public listed variants only and is not a claim that the list is exhaustive.
Site guidance on per-vial size versus pack quantity is editorial, not independent scientific evidence. Read per-vial size, vials per pack, and pack price as separate fields. A description such as 10 mg × 10 vials means ten vials of nominal 10 mg each, not one 100 mg vial. KS5 is ten vials of nominal 5 mg each, not one 50 mg vial. The pack sum is label arithmetic, not an analytical measurement; actual fill and peptide content belong to the batch report.
| Field | KS5 | KS10 |
|---|---|---|
| Product | Kisspeptin | Kisspeptin |
| SKU | KS5 | KS10 |
| Nominal size per vial | 5 mg | 10 mg |
| Vials per pack | 10 | 10 |
| Nominal sum across one pack | 50 mg | 100 mg |
If a quotation uses a different packaging description, ask support to reconcile it before relying on the calculation.
Match the batch number to the published COA
A SKU identifies a listed variant; a batch number identifies a batch record. Editorial guidance on finding a COA by SKU and batch says to compare product name, SKU, batch, and certificate number. Select the SKU on the product page so the matching certificate panel updates. Do not use a KS5 report as evidence for KS10, and do not treat an older published lot as the lot that will ship next. A missing public result is neither a failed test nor a passed test.
The two records below apply only to the named batch and SKU. Provider verification links were not independently fetched. They are not evidence of clinical suitability or of every batch.
KS5 — batch [8DVI01GS4CS8](https://certipeptide.com/en/lab-reports/kisspeptin/8DVI01GS4CS8). Certificate QC-2026-ZKWFFHHW2S; laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group); test date 2026-08-12; SKU KS5, 5 mg. Analyte on each test row: Kisspeptin KS5.

KS10 — batch [SIHIO7QD0346](https://certipeptide.com/en/lab-reports/kisspeptin/SIHIO7QD0346). Certificate QC-2026-JJ32BHLQ6X; laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group); test date 2026-08-12; SKU KS10, 10 mg. Analyte on each test row: Kisspeptin KS10.
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 1302.5 +/- 1.0 Da | 1301.6 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.2 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.9 % | Pass |

| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
Catalog size and gravimetric fill are different fields: KS5 is listed at 5 mg with recorded fill 5.78 mg on batch 8DVI01GS4CS8; KS10 is listed at 10 mg with recorded fill 11.34 mg on batch SIHIO7QD0346.
Verify the certificate against the original report
Editorial guidance on how to verify a CertiPeptide COA starts by matching product name, SKU, and batch number. Compare certificate number and test date with the original report, then use that report’s verification link. A verification page may require a provider account; a link alone does not prove the report is currently valid.
- Read product and SKU from the product page or order documentation.
- Locate the batch; if the allocated batch is not stated, ask support to confirm it.
- Check certificate number, sample identity, test date, and listed laboratory.
- Compare values and units with the original report.
- Follow the report-specific verification link. If login is required or the record cannot be confirmed, resolve that before treating verification as complete.
A published report does not mean every order receives that batch. Confirm the allocated batch separately. When details differ, send support the SKU, batch number, and the specific difference. A screenshot can help comparison; the original document and provider record are stronger evidence.
These certificates do not record sterility, storage temperature, shipping performance, or use suitability. An unlisted test is unknown—not zero, not a pass, and not evidence of absence.
Checklist
- Confirm the product name Kisspeptin and the exact SKU (KS5 or KS10).
- Confirm per-vial size (5 mg or 10 mg) and 10 vials per pack.
- Confirm batch number and certificate number on the SKU-specific batch page.
- Compare each analyte, method, specification, result, unit, and determination with the original report.
- Do not apply KS5 results to KS10, or the reverse.
- Treat a missing public COA as unknown, not as pass or fail.
Frequently Asked Questions
Which Kisspeptin SKUs are publicly listed?
The public listing shows KS5 (nominal 5 mg per vial, 10 vials per pack) and KS10 (nominal 10 mg per vial, 10 vials per pack). That table is public listed variants only and is not a claim that the list is exhaustive.
Can the KS5 COA be used as evidence for KS10?
No. A report for one SKU should not be used as evidence for another size merely because both are labeled Kisspeptin. Batch 8DVI01GS4CS8 applies only to KS5; batch SIHIO7QD0346 applies only to KS10.
Do published batches 8DVI01GS4CS8 and SIHIO7QD0346 ship with every order?
No. A published report does not mean every order receives that batch. Confirm the batch allocated to the order separately.
What if a Kisspeptin COA is not published for the allocated batch?
Ask support for the exact SKU and batch. A missing public result is not automatically a failed test, and it is not a passed test either.
What purity and actual fill were recorded on the two published Kisspeptin COAs?
For KS5 batch 8DVI01GS4CS8 (certificate QC-2026-ZKWFFHHW2S), HPLC purity was 98.7 % and gravimetric actual fill was 5.78 mg. For KS10 batch SIHIO7QD0346 (certificate QC-2026-JJ32BHLQ6X), HPLC purity was 99.2 % and gravimetric actual fill was 11.34 mg.
