To verify a listed KPV material, match the product name, SKU, per-vial size, pack quantity, and batch certificate of analysis (COA) as separate identifiers. The product name alone is not enough when more than one size exists. Catalog sizes are nominal; recorded laboratory results apply only to the named batch and SKU.
Listed KPV SKUs, vial size, and packaging
The public KPV product listing records CAS number 67727-97-3, molecular formula C16H30N4O4, and molecular weight 342.4. Two public SKUs appear there: KP5, with a nominal 5 mg per vial and 10 vials per pack, and KP10, with a nominal 10 mg per vial and 10 vials per pack. That table is described as public listed variants only, at most 40; it is not a claim that the list is exhaustive.
Per-vial size versus pack quantity is site editorial guidance, not independent scientific evidence. It advises reading the per-vial size, vials per pack, and pack price as three separate fields. A label such as “10 mg × 10 vials” describes ten vials with a nominal size of 10 mg each. It is not a single vial containing 100 mg. The milligram sum across one pack is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report.
| Field | KP5 | KP10 |
|---|---|---|
| SKU | KP5 | KP10 |
| Nominal size per vial | 5 mg | 10 mg |
| Vials per pack | 10 | 10 |
| Nominal pack sum (label arithmetic) | 50 mg | 100 mg |
The same editorial page lists a check-before-ordering sequence: match the exact product and SKU; check the per-vial size and unit; check the number of vials per pack; set the number of packs required; and review matching batch records and order details. If a quotation uses a different packaging description, ask support to reconcile it before relying on the calculation.
How to find and match a KPV COA
A SKU identifies a listed product variant. A batch number identifies a batch record. Use both when locating a COA. How to find a COA by SKU and batch is editorial guidance: open the product page, select the SKU, and read the matching certificate panel. A product name by itself is not enough when several sizes or batches exist.
Avoid two common mismatches described there: a report for one size should not be used as evidence for another merely because both share a product name, and an older published batch is not evidence of the batch that will be shipped next. A KP5 report is therefore not evidence for KP10. A missing public result is not automatically a failed test, and it is not a passed test either. If a previously shared report link is no longer available, ask support for the current documentation rather than substituting a different batch.
How to verify a CertiPeptide COA starts by matching product name, SKU, and batch number. Open the original report and compare its certificate number and test date with the summary, then use the verification link for that report. A verification page may require an account with the report provider; seeing a link alone does not prove that a report is currently valid. If the provider requests login or the record cannot be confirmed, resolve that with the provider or support before treating verification as complete. Provider verification links on the published KPV records below were not independently fetched.
A published report does not mean every order receives that batch. Confirm the batch allocated to the order separately.
Published KP5 batch 5KJTLL7XEV9V
One published COA for SKU KP5 (5 mg) is KPV batch 5KJTLL7XEV9V, certificate QC-2026-WXWQZ6YSY5, test date 2026-08-21, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group). The record’s scope is published recorded results for this batch only. It is not evidence of clinical suitability or of every batch.
Tests recorded for analyte KPV KP5:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 342.4 +/- 1.0 Da | 341.8 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.1 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.7 % | Pass |
| Actual fill | Gravimetric | 5 mg | 5.73 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 4.3 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
The same page’s summary reports identity 341.8 Da, purity 99.1 %, weight 5.73 mg, and endotoxin <3 EU/mg, each with resultPass true. Gravimetric fill 5.73 mg is a measurement for this KP5 batch; it is not the catalog nominal 5 mg and is not evidence for KP10.
Published KP10 batch OY2PJKIMIOAC
One published COA for SKU KP10 (10 mg) is KPV batch OY2PJKIMIOAC, certificate QC-2026-DXTSBMX89K, test date 2026-08-21, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group). The same batch-only scope applies.
Tests recorded for analyte KPV KP10:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 342.4 +/- 1.0 Da | 341.6 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.0 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 93.0 % | Pass |
| Actual fill | Gravimetric | 10 mg | 11.49 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 4.7 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
Summary reports on that record list identity 341.6 Da, purity 99.0 %, weight 11.49 mg, and endotoxin <3 EU/mg, each with resultPass true. Peptide content 93.0 % (HPLC) and actual fill 11.49 mg (gravimetric) are different tests; neither replaces the other, and neither is a KP5 result.
Verification checklist
- Match product name KPV and the exact SKU (KP5 or KP10).
- Confirm nominal per-vial size and unit, then vials per pack (10 on both listed SKUs).
- Keep pack-sum milligrams as label arithmetic, not a measured fill.
- Open the COA whose batch number and SKU match; do not borrow the other size’s report.
- Compare certificate number, test date, laboratory, analyte, methods, units, specifications, results, and determinations with the original report.
- Follow that report’s verification link. Login-protected provider pages are not confirmed by the catalog site.
- Confirm the batch allocated to the order separately from these published examples.
- If details differ, send support the SKU, batch number, and the specific difference rather than substituting another record.
Unknown tests are not zero, pass, or evidence of absence. Named-batch appearance, water, and bacterial-endotoxin results are not sterility, safety, storage, shipping, or clinical-suitability conclusions.
Frequently Asked Questions
Which KPV SKUs are on the public listing?
The public listing shows KP5 (nominal 5 mg per vial, 10 vials per pack) and KP10 (nominal 10 mg per vial, 10 vials per pack). That table is public listed variants only, at most 40, and is not a claim that the list is exhaustive.
Does “10 mg × 10 vials” mean one 100 mg vial?
No. That label describes ten vials with a nominal size of 10 mg each. The milligram sum across one pack is label arithmetic, not an analytical measurement.
Can a KP5 COA be used as evidence for KP10?
No. A report for one size should not be used as evidence for another merely because both share the product name KPV. Match product name, SKU, and batch number.
Does a published KPV COA 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 if the COA verification provider requires login?
Use the provider’s normal access process. Seeing a link alone does not prove that a report is currently valid, and the catalog site does not independently confirm the current status of a login-protected record.
