To verify a listed NAD+ item, match the exact SKU, the nominal size of each vial, the number of vials in the pack, and the batch certificate that belongs to that SKU. A product name alone is not enough when several sizes exist. A published COA is recorded evidence only for the named batch and SKU, not for every future shipment.
Listed NAD+ SKUs and pack quantity
The public NAD+ product page lists CAS number 53-84-9, molecular formula C21H27N7O14P2, and molecular weight 663.4. Three public SKUs are shown: NJ100 (100 mg per vial, 10 vials per pack), NJ500 (500 mg per vial, 10 vials per pack), and NJ1000 (1000 mg per vial, 10 vials per pack). The catalog describes that list as public listed variants only, at most 40, and not a claim that the list is exhaustive.
Site editorial guidance on per-vial size versus pack quantity treats per-vial size, vials per pack, and pack price as three separate fields. That page is editorial guidance, not independent laboratory evidence. A description such as 100 mg × 10 vials means ten vials with a nominal size of 100 mg each; it is not a single vial containing 1,000 mg. The sum across one pack is label arithmetic, not an analytical measurement. Actual fill belongs to the particular batch report.
| SKU | Nominal size per vial | Vials per pack |
|---|---|---|
| NJ100 | 100 mg | 10 |
| NJ500 | 500 mg | 10 |
| NJ1000 | 1000 mg | 10 |
If a quotation uses a different packaging description, ask support to reconcile it before relying on the calculation.
Match SKU and batch before using a COA
A SKU identifies a listed product variant. A batch number identifies a batch record. How to find a COA by SKU and batch number advises using both: open the product page, select the SKU, and read the matching certificate panel. Selecting a SKU updates the report without moving the viewing position.
Do not use an NJ100 report as evidence for NJ500 or NJ1000 merely because all three say NAD+. An older published batch is not evidence of the batch that will be shipped next. 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.
Published batch COAs for NJ100, NJ500, and NJ1000
Three published NAD+ COA records are provided, one for each listed SKU. Each record states that the results apply to that batch only, that provider verification links were not independently fetched, and that the document is not evidence of clinical suitability or of every batch. All three name Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group) and a test date of 2026-08-18.
- Batch MD02CYC0QDNW: SKU NJ100, certificate QC-2026-X78HARZPTW, analyte NAD+ NJ100. Appearance (Visual) was white loose powder against white or almost white loose powder (Pass).
- Batch E1XRT49HQY6T: SKU NJ500, certificate QC-2026-YK2LJJV5LV, analyte NAD+ NJ500. Appearance (Visual) was white loose powder against white or almost white loose powder (Pass).
- Batch QSK803W3KZA2: SKU NJ1000, certificate QC-2026-4ZRZ5NUJMG, analyte NAD+ NJ1000. Appearance (Visual) was white loose powder against white or almost white loose powder (Pass).
Shared specifications on these three reports: mass spectrum 663.4 +/- 1.0 Da (MS); purity NLT 98.0 % (HPLC); assay 98.0-102.0 % (HPLC); water content NMT 8.0 % (Karl Fischer); bacterial endotoxins NMT 10 EU/mg (LAL (gel-clot)). Actual-fill specifications (Gravimetric) were 100 mg, 500 mg, and 1000 mg respectively. Every listed item on these three reports was recorded as Pass.
| Item (method) | NJ100 MD02CYC0QDNW | NJ500 E1XRT49HQY6T | NJ1000 QSK803W3KZA2 |
|---|---|---|---|
| Mass spectrum (MS) | 662.9 Da | 662.9 Da | 662.6 Da |
| Purity (HPLC) | 99.4 % | 99.2 % | 99.1 % |
| Assay (HPLC) | 100.6 % | 99.8 % | 99.7 % |
| Actual fill (Gravimetric) | 108.29 mg | 594.41 mg | 1148.24 mg |
| Water content (Karl Fischer) | 4.2 % | 4.8 % | 4.9 % |
| Bacterial endotoxins (LAL (gel-clot)) | <3 EU/mg | <3 EU/mg | <3 EU/mg |
Those values are the recorded determinations for those three batches only. They do not describe unlisted SKUs, and they are not a stand-in for a later allocated batch.
Confirm the certificate, then the original report
How to verify a CertiPeptide COA starts with 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. The website does not independently confirm the current status of a login-protected record.
Practical sequence:
- Read the product and SKU from the product page or order documentation.
- Find the batch among published lab reports. If the allocated batch is not stated, ask support to confirm it.
- Open the batch page and check the certificate number, sample identity, test date, and listed laboratory.
- Open the original report and compare the values and units with the summary.
- Follow the report-specific verification link. If the provider requests login or the record cannot be confirmed, resolve that with the provider or support before treating verification as complete.
When details differ, do not substitute a report for a similar product or a different size. Send support the SKU, batch number, and the specific difference. A screenshot is useful for comparison, but the original document and provider record are stronger verification evidence. A published report does not mean every order receives that batch; confirm the batch allocated to the order separately.
Verification checklist
- Confirm the product is NAD+ and the SKU is NJ100, NJ500, or NJ1000 as listed on the NAD+ product page.
- Read nominal size per vial and 10 vials per pack as separate fields; do not treat pack-sum arithmetic as measured fill.
- Locate the COA with SKU and batch number together, then match certificate number, test date, laboratory, and analyte (NAD+ plus the SKU).
- Compare each result, method, unit, qualifier (including NLT, NMT, +/-, and <), and Pass determination with the original report.
- Do not apply one SKU fill, purity, water, or endotoxin result to another SKU or to an unlisted batch.
- If a public report is missing or a verification link cannot be confirmed, treat that as unknown—not as a pass, a fail, or evidence of absence—and ask support for the allocated batch.
Frequently Asked Questions
Does a published NAD+ COA mean every order receives that batch?
No. Confirm the batch allocated to the order separately. A published report is not a promise that a future order will receive that batch.
Can an NJ100 COA be used as evidence for NJ500 or NJ1000?
No. A report for one NAD+ SKU should not be used as evidence for another size merely because both say NAD+. Match product name, SKU, and batch number together.
What if a public NAD+ COA is missing?
A missing public result is not automatically a failed test, and it is not a passed test either. Ask support for the exact SKU and batch rather than substituting a different batch.
What identifiers should I match on a NAD+ certificate?
Match product name, SKU, batch number, certificate number, test date, sample identity, and listed laboratory, then compare values and units with the original report.
