To verify Thymosin Alpha-1, match the listed SKU, the nominal milligrams in each vial, and the number of vials in the pack, then open the certificate of analysis (COA) that names that same SKU and batch. A product name by itself is not enough when more than one size is published, and a report for one lot is not evidence for another size or a later shipment.
Listed SKUs, vial size and pack quantity
The public Thymosin Alpha-1 listing records CAS number 62304-98-7, molecular formula C129H215N33O55 and molecular weight 3108.3. Two public SKUs are shown: TA5, with a nominal 5 mg per vial and 10 vials per pack, and TA10, with a nominal 10 mg per vial and 10 vials per pack. Those entries are public listed variants only; at most 40, not a claim that the list is exhaustive.
Site editorial guidance on reading a product SKU 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. It is not a single vial containing 100 mg. The arithmetic sum across a pack is label math, not an analytical measurement. Actual fill and peptide-content values belong to the particular batch report.
| SKU | Nominal size per vial | Vials per pack |
|---|---|---|
| TA5 | 5 mg | 10 |
| TA10 | 10 mg | 10 |
Before treating a quotation as complete, 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. If other documentation uses a different packaging description, reconcile it before relying on the calculation.
Published batch COAs for TA5 and TA10
A SKU identifies a listed product variant. A batch number identifies a batch record. Site editorial guidance on finding a COA by SKU and batch number is to use both identifiers. Do not use a TA5 report as evidence for TA10 merely because both say Thymosin Alpha-1, and do not treat an older published batch as evidence of the lot that will be shipped next.
Two published records show how those identifiers line up.
For SKU TA5, batch TGFJJ3A0JK14 carries certificate number QC-2026-TF6GHL8G3W. The listed laboratory is Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), and the test date is 2026-04-08. The analyte on each line is Thymosin Alpha-1 TA5. Recorded tests:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 3108.3 +/- 1.0 Da | 3108.0 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 98.9 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.6 % | Pass |
| Actual fill | Gravimetric | 5 mg | 5.67 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 3.4 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
Summary values on that TA5 record are identity 3108.0 Da, purity 98.9 %, weight 5.67 mg and endotoxin <3 EU/mg.
For SKU TA10, batch OGFALAG6ZIMK carries certificate number QC-2026-SUC9YFRDTB, the same laboratory name, and the same test date of 2026-04-08. The analyte on each line is Thymosin Alpha-1 TA10. Recorded tests:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 3108.3 +/- 1.0 Da | 3107.7 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 98.8 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 91.1 % | Pass |
| Actual fill | Gravimetric | 10 mg | 11.05 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 |
Summary values on that TA10 record are identity 3107.7 Da, purity 98.8 %, weight 11.05 mg and endotoxin <3 EU/mg.
These figures apply only to the named batch and SKU. They are not evidence of every Thymosin Alpha-1 lot, of sterility, or of clinical suitability. Provider verification links on the records were not independently fetched. A missing public result is not a failed test and is not a passed test either.
Matching identifiers and checking a certificate
Site editorial guidance on 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.
A practical sequence is:
- Read the product and SKU from the product page or order documentation.
- Find the batch in the 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.
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 can help comparison, but the original document and provider record are stronger verification evidence. If a previously shared report link is no longer available, ask support for the current documentation rather than substituting a different batch. A published report does not mean every order receives that batch; confirm the allocated batch separately.
Checklist before you rely on a listing
- Product name is Thymosin Alpha-1.
- SKU is the selected TA5 or TA10 listing, with 5 mg or 10 mg per vial and 10 vials per pack as published.
- Batch number on the allocation matches the COA page, not a neighboring lot.
- Certificate number, test date and laboratory match the original report.
- Each analyte, method, unit and qualifier (including < on endotoxin) is copied as recorded; a blank field is not zero and is not a pass.
- Actual fill and peptide content are taken from that batch report, not from pack-sum arithmetic.
Frequently Asked Questions
Can a TA5 certificate be used as evidence for TA10?
No. A report for one listed size should not be used as evidence for another size merely because both are named Thymosin Alpha-1. Match product, SKU and batch together.
Does a published Thymosin Alpha-1 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 public vial sizes are listed for Thymosin Alpha-1?
The public listing shows SKU TA5 at 5 mg per vial with 10 vials per pack, and SKU TA10 at 10 mg per vial with 10 vials per pack. That is not a claim that the list is exhaustive.
What if a public 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.
