To verify Semax, match the exact SKU, the nominal milligrams in each vial and the number of vials in the pack, then open the certificate of analysis that names the same SKU and batch. Catalog sizes are nominal listed values. Each published COA records results for one named batch and SKU only; it is not evidence of clinical suitability or of every later shipment.
Confirm the listed SKU, vial size and pack quantity
The public Semax specification lists CAS number 80714-61-0, molecular formula C37H51N9O10S and molecular weight 813.9. Two public variants are shown: SKU SX5, nominal 5 mg per vial with 10 vials per pack, and SKU SX10, nominal 10 mg per vial with 10 vials per pack. The listing describes these as public listed variants only, at most 40, and is not a claim that the list is exhaustive (Semax).
Editorial site guidance treats 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, 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. If a quotation uses a different packaging description, ask support to reconcile it before relying on the calculation (Per-vial size versus pack quantity).
| Field | SX5 | SX10 |
|---|---|---|
| Product | Semax | Semax |
| SKU | SX5 | SX10 |
| Nominal size per vial | 5 mg | 10 mg |
| Vials per pack | 10 | 10 |
Those fields are catalog listings, not gravimetric COA results (Semax). Physical carton materials, storage temperature and shipping condition are not described on the product listing or these published batch records.
Match the COA to the same SKU and batch
A SKU identifies a listed product variant; a batch number identifies a batch record. A product name by itself is not enough when several sizes or batches exist. Do not use an SX5 report as evidence for SX10, and do not treat an older published batch as the lot that will ship next. A missing public result is neither a failed test nor a passed test (How to find a COA by SKU and batch).
Match product name, SKU and batch number first. 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. A published report does not mean every order receives that batch (How to verify a CertiPeptide COA).
The certificates below are published recorded results for those batches only. Provider verification links were not independently fetched. They are not evidence of clinical suitability or of every batch.
SX5 batch XDMN4VEFXOWW
Batch XDMN4VEFXOWW is recorded for SKU SX5 (5 mg) under certificate QC-2026-PBSLMKL94J, tested 2026-08-24 by Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group). The analyte on each listed test is Semax XA5 (Semax — batch XDMN4VEFXOWW).
| Item | Analyte | Method | Specification | Result | Determination |
|---|---|---|---|---|---|
| Appearance | Semax XA5 | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | Semax XA5 | MS | 813.9 +/- 1.0 Da | 813.0 Da | Pass |
| Purity | Semax XA5 | HPLC | NLT 98.0 % | 98.7 % | Pass |
| Peptide content | Semax XA5 | HPLC | NLT 90.0 % | 90.6 % | Pass |
| Actual fill | Semax XA5 | Gravimetric | 5 mg | 5.59 mg | Pass |
| Water content | Semax XA5 | Karl Fischer | NMT 8.0 % | 5.7 % | Pass |
| Bacterial endotoxins | Semax XA5 | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
The same record’s summary rows list identity 813.0 Da, purity 98.7 %, weight 5.59 mg and endotoxin <3 EU/mg.
SX10 batch K1TT9FVXXGDC
Batch K1TT9FVXXGDC is recorded for SKU SX10 (10 mg) under certificate QC-2026-EYT7V2BAF5, tested 2026-08-02 by Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group). The analyte on each listed test is Semax XA10 (Semax — batch K1TT9FVXXGDC).
| Item | Analyte | Method | Specification | Result | Determination |
|---|---|---|---|---|---|
| Appearance | Semax XA10 | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | Semax XA10 | MS | 813.9 +/- 1.0 Da | 813.1 Da | Pass |
| Purity | Semax XA10 | HPLC | NLT 98.0 % | 99.4 % | Pass |
| Peptide content | Semax XA10 | HPLC | NLT 90.0 % | 90.3 % | Pass |
| Actual fill | Semax XA10 | Gravimetric | 10 mg | 11.43 mg | Pass |
| Water content | Semax XA10 | Karl Fischer | NMT 8.0 % | 4.7 % | Pass |
| Bacterial endotoxins | Semax XA10 | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
The same record’s summary rows list identity 813.1 Da, purity 99.4 %, weight 11.43 mg and endotoxin <3 EU/mg.
These records do not establish sterility. Endotoxin rows are the recorded LAL (gel-clot) values for those batches. Unlisted tests are unknown, not zero, and not evidence of absence. Gravimetric fill (5.59 mg on SX5; 11.43 mg on SX10) is not the same as the nominal catalog size or the HPLC peptide-content results (90.6 % and 90.3 %).
Checklist for SKU, pack and COA checks
- Match product name Semax and the exact SKU (SX5 or SX10) on the product page.
- Record nominal milligrams per vial and vials per pack as separate fields; do not treat the pack sum as a measured fill (pack-quantity guidance).
- Obtain the batch number allocated to the order. A published example batch is not a promise of the next shipment (COA verification guidance).
- Open the batch page and compare SKU, batch number, certificate number, test date, laboratory name and analyte (Semax XA5 or Semax XA10).
- Compare each analyte, method, unit, qualifier and determination with the original report. Keep language such as
<3 EU/mg,NLTandNMTintact. - Follow the report-specific verification link if provider confirmation is required. If login is needed or the record cannot be confirmed, resolve that before treating verification as complete.
- If a previously shared report link is no longer available, ask support for current documentation rather than substituting a different batch (finding a COA).
Frequently Asked Questions
Which Semax SKUs are listed on the public product page?
The public listing shows SX5 (5 mg per vial, 10 vials per pack) and SX10 (10 mg per vial, 10 vials per pack). It states these are public listed variants only, at most 40, and is not a claim that the list is exhaustive.
Does a published Semax COA mean the next order will receive that batch?
No. A published report does not mean every order receives that batch. Confirm the batch allocated to the order separately.
Can the SX5 certificate be used as evidence for SX10?
No. A SKU identifies a listed product variant. A report for one size should not be used as evidence for another size merely because both are named Semax.
What should match when verifying a Semax COA?
Match product name, SKU and batch number, then compare certificate number, test date, laboratory name and the original report values and units with the summary. Seeing a verification link alone does not prove the report is currently valid.
