Tesamorelin catalog records identify the compound, then split each public variant by SKU, per-vial size, and pack quantity. To verify a vial, match the exact SKU to the batch number and certificate on the matching published COA. Another size, another batch, or a pack-total calculation is not a substitute for the matching record.
Public SKUs, vial size, and pack quantity
The Tesamorelin product listing records the name Tesamorelin, CAS number 218949-48-5, molecular formula C221H366N72O67S, and molecular weight 5135.9. Public listed variants include the five SKUs below. The listing describes these as public listed variants only, at most 40, and is not a claim that the list is exhaustive.
| SKU code | Nominal size per vial | Vials per pack |
|---|---|---|
| TSM2 | 2 mg | 10 |
| TSM5 | 5 mg | 10 |
| TSM10 | 10 mg | 10 |
| TSM20 | 20 mg | 10 |
| TSM40 | 40 mg | 10 |
Site editorial guidance on per-vial size versus pack quantity 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 sum across a pack is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report.
On that listing, TSM2, TSM5, TSM10, TSM20, and TSM40 each use a 10-vial pack at the nominal per-vial size in the table. Before ordering, the same guide recommends matching the exact product and SKU, checking the per-vial size and unit, checking vials per pack, setting the number of packs required, and reviewing matching batch records. 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. Use both when locating a COA. The product name Tesamorelin alone is not enough when several sizes or batches exist. A report for TSM2 should not be used as evidence for TSM10 merely because both say Tesamorelin. An older published batch is not 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. 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 TSM2, TSM5, and TSM10
Three published Tesamorelin COAs are linked below. Each record covers published recorded results for that batch only. Provider verification links were not independently fetched. These records are not evidence of clinical suitability or of every batch. No published COA for TSM20 or TSM40 is included here.
All three name the laboratory as Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group) and record test date 2026-08-06.
| SKU | Batch | Certificate | Mass spectrum | HPLC purity | Gravimetric fill | Endotoxin |

Batch 3OMX3N8TDZSO is SKU TSM2, 2 mg, certificate QC-2026-4NSM75PAE5. Analyte Tesamorelin TSM2: Appearance, Visual, specification White or almost white loose powder, result White loose powder, determination Pass.

Batch CX943TO66PKQ is SKU TSM5, 5 mg, certificate QC-2026-NNKHZWWYU2. Analyte Tesamorelin TSM5: Appearance, Visual, specification White or almost white loose powder, result White loose powder, Pass.

Batch NTQHNT1U2FO3 is SKU TSM10, 10 mg, certificate QC-2026-DZ7N68MLKG. Analyte Tesamorelin TSM10: Appearance, Visual, specification White or almost white loose powder, result White loose powder, Pass. Mass spectrum, MS, specification 5135.9 +/- 1.0 Da, result 5135.3 Da, Pass. Purity, HPLC, specification NLT 98.0 %, result 98.9 %, Pass.

Water content, Karl Fischer, specification NMT 8.0 %, result 3.7 %, Pass. Bacterial endotoxins, LAL (gel-clot), specification NMT 10 EU/mg, result <3 EU/mg, Pass.
Nominal catalog size and gravimetric actual fill are different fields. On these three batches the recorded fills were 2.28 mg versus a 2 mg specification, 5.76 mg versus 5 mg, and 11.06 mg versus 10 mg. Those values apply only to the named batch and SKU.
Verification sequence and checklist
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. The site does not independently confirm the current status of a login-protected record. A published report does not mean every order receives that batch; confirm the batch allocated to the order separately. Do not substitute a report for a similar product or a different size.
| Step | What to check |
|---|---|
| 1 | Confirm product name Tesamorelin and the exact SKU on the product page or order documentation. |
| 2 | Confirm nominal size per vial and 10 vials per pack; do not treat pack-sum arithmetic as a measured fill. |
| 3 | Locate batch number and certificate number on the matching batch page. If the allocated batch is not stated, ask support to confirm it. |
| 4 | Compare certificate number, sample identity (including the TSM analyte), test date, and laboratory name with the original report. |
| 5 | Compare each result, unit, qualifier, method, and determination with the summary. Do not carry TSM2 results over to TSM5 or TSM10. |
| 6 | 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. |
| 7 | If details differ, send support the SKU, batch number, and the specific difference rather than substituting another published Tesamorelin batch. |
These steps describe how to read the listed catalog and the three published batch records. They do not fill gaps for unpublished SKUs, untested attributes, or batches that are not published here.
Frequently Asked Questions
Which Tesamorelin SKUs are publicly listed?
The Tesamorelin product listing includes TSM2 (2 mg), TSM5 (5 mg), TSM10 (10 mg), TSM20 (20 mg), and TSM40 (40 mg), each with 10 vials per pack. The listing is public listed variants only, at most 40, and is not a claim that the list is exhaustive.
Does a 10 mg × 10 vial Tesamorelin pack mean one 100 mg vial?
No. Per-vial size, vials per pack, and pack price are three separate fields. A label such as 10 mg × 10 vials describes ten vials with a nominal size of 10 mg each. The pack sum is label arithmetic, not an analytical measurement.
Can a TSM2 COA be used as evidence for TSM10 Tesamorelin?
No. A SKU identifies a listed product variant and a batch number identifies a batch record. A report for one size should not be used as evidence for another merely because both say Tesamorelin.
Does a published Tesamorelin 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 HPLC purity values are recorded on the published TSM2, TSM5, and TSM10 COAs?
Batch 3OMX3N8TDZSO (TSM2) recorded 98.8 % HPLC purity against NLT 98.0 %. Batch CX943TO66PKQ (TSM5) recorded 99.4 %. Batch NTQHNT1U2FO3 (TSM10) recorded 98.9 %. Each result applies only to that named batch and SKU.
