Match the listed SKU, the per-vial size and the pack quantity as three separate fields, then open the certificate that names the same SKU and batch. For Melanotan I, the public catalog lists SKU MT1 at 10 mg per vial with 10 vials per pack. A published laboratory record for batch 71Z7OWSBX7ED is evidence for that batch only (batch 71Z7OWSBX7ED).
Confirm SKU MT1, vial size and pack layout
The Melanotan I product specification lists CAS number 75921-69-6, molecular formula C78H111N21O19 and molecular weight 1646.9. SKU MT1 is recorded with nominal size 10 mg per vial and 10 vials per pack. That SKU scope covers public listed variants only (at most 40) and is not a claim that the list is exhaustive.
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, each with a nominal size of 10 mg. It is not a single vial containing 100 mg. Multiplying size by vial count (100 mg for this listing) is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report.
The same guidance lists a check before ordering: 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. Selecting a different SKU can change pack price and available stock. Catalog size and pack figures remain nominal and should not replace gravimetric fill or HPLC peptide-content results on a named certificate.
Read the published COA for batch 71Z7OWSBX7ED
The Melanotan I batch 71Z7OWSBX7ED certificate records results for that batch only. It names certificate number QC-2026-Y6JSNE33HN, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), test date 2026-06-29, and SKU MT1 at 10 mg. Provider verification links were not independently fetched. The record is not evidence of clinical suitability or of every batch.
Summary rows record Identity 1646.0 Da (Pass), Purity 99.5 % (Pass), Weight 11.85 mg (Pass) and Endotoxin <3 EU/mg (Pass).
Detailed tests for analyte Melanotan I MT1:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 1646.9 +/- 1.0 Da | 1646.0 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.5 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 90.7 % | Pass |
| Actual fill | Gravimetric | 10 mg | 11.85 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 4.5 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
Keep analyte, method, units, qualifiers and determinations as recorded. The gravimetric actual fill of 11.85 mg is a batch measurement against a 10 mg specification with determination Pass; it does not rewrite the catalog nominal size of 10 mg per vial (product specification). HPLC peptide content of 90.7 % is a separate result from HPLC purity 99.5 %. An endotoxin result of <3 EU/mg against NMT 10 EU/mg is not a sterility, safety or shipping conclusion, and unlisted analytes are not shown as absent.
No other Melanotan I SKUs or batches appear on the cited product and batch pages. A missing public certificate is not a pass, a fail or proof that another lot matches these numbers.
Locate the COA by SKU and batch
A guide to finding a COA by SKU and batch treats a SKU as the listed product variant and a batch number as the batch record. Use both. A product name alone is not enough when several sizes or batches exist. Open the product page, select the SKU and read the matching certificate panel.
Avoid two mismatches: do not use a report for a different size merely because both documents say Melanotan I, and do not treat an older published batch as evidence of the batch that will be shipped next. If a public result is missing, 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.
How to verify a CertiPeptide COA starts by matching product name, SKU and batch number, then comparing certificate number and test date with the summary, and using 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 before treating verification as complete. A published report does not mean every order receives that batch. Confirm the allocated batch separately. Do not substitute a report for a similar product or a different size.
Verification checklist
| Check | What to match | Documented example |
|---|---|---|
| Product name | Exact listed name | Melanotan I |
| SKU | Listed size and pack variant | MT1 |
| Per-vial size | Nominal size and unit | 10 mg |
| Vials per pack | Pack quantity, not a combined vial | 10 |
| Batch | Batch on the certificate | 71Z7OWSBX7ED |
| Certificate | Issued report number | QC-2026-Y6JSNE33HN |
| Test date and lab | As printed on the batch page | 2026-06-29; Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group) |
- Confirm product name Melanotan I and SKU MT1 on the product page.
- Confirm 10 mg per vial and 10 vials per pack as separate fields, not as one 100 mg vial (pack-quantity guidance).
- Confirm the allocated batch number; do not assume it is 71Z7OWSBX7ED.
- Open the matching batch page only when that batch is the one in hand, and compare certificate number, SKU, test date and laboratory.
- Compare each analyte, method, unit, qualifier and determination with the original report.
- Use the report-specific verification process; login-protected provider pages are not independently confirmed by the catalog site (COA verification guidance).
- If any identifier differs, stop and ask support to reconcile SKU, batch and the specific difference.
Only SKU MT1 and batch 71Z7OWSBX7ED appear on the cited product and batch pages. Catalog identity values and this batch’s HPLC, MS, gravimetric, Karl Fischer and LAL results do not extend to unlisted SKUs or other lots.
Frequently Asked Questions
What SKU, vial size and pack quantity are listed for Melanotan I?
The public product page lists SKU MT1 with a nominal size of 10 mg per vial and 10 vials per pack. That SKU scope covers public listed variants only (at most 40) and is not a claim that the list is exhaustive.
How should 10 mg × 10 vials be read for SKU MT1?
It describes ten vials with a nominal size of 10 mg each, 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.
Does the published COA for batch 71Z7OWSBX7ED apply to every Melanotan I order?
No. The record is published recorded results for that batch only and is not evidence of every batch. A published report does not mean every order receives that batch; confirm the allocated batch separately.
What identity, purity, fill and endotoxin values are recorded on certificate QC-2026-Y6JSNE33HN?
For analyte Melanotan I MT1 on batch 71Z7OWSBX7ED, mass spectrum is 1646.0 Da (specification 1646.9 +/- 1.0 Da), HPLC purity is 99.5 % (NLT 98.0 %), HPLC peptide content is 90.7 % (NLT 90.0 %), gravimetric actual fill is 11.85 mg (specification 10 mg), and bacterial endotoxins are <3 EU/mg (NMT 10 EU/mg). Each of those items has determination Pass.
What if a public Melanotan I COA is missing 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. Do not substitute a report for a different size or batch.
