To verify a Tirzepatide research listing, match the SKU code, the nominal milligrams per vial, and the vials-per-pack figure, then confirm that any certificate of analysis (COA) belongs to that same SKU and a named batch. Catalog sizes are nominal. Fill, purity, and other analytical results apply only to the tested batch and SKU. A product name alone is not enough when several sizes exist.
Match the SKU, vial size, and pack quantity
The public Tirzepatide product listing identifies the compound as Tirzepatide, CAS number 2023788-19-2, molecular formula C225H348N48O68, and molecular weight 4813.5. The same listing states that SKU coverage is public listed variants only, at most 40, and is not a claim that the list is exhaustive.
Each public listed variant uses a TR-prefixed SKU, a nominal size per vial in mg, and 10 vials per pack:
| SKU | Nominal size per vial | Vials per pack |
|---|---|---|
| TR5 | 5 mg | 10 |
| TR10 | 10 mg | 10 |
| TR15 | 15 mg | 10 |
| TR20 | 20 mg | 10 |
| TR30 | 30 mg | 10 |
| TR40 | 40 mg | 10 |
| TR50 | 50 mg | 10 |
| TR60 | 60 mg | 10 |
| TR80 | 80 mg | 10 |
| TR100 | 100 mg | 10 |
| TR120 | 120 mg | 10 |
Those values are catalog fields from the Tirzepatide product listing, not batch measurements.
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 sum across one pack is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report (per-vial size versus pack quantity).
Applied to listed Tirzepatide SKUs, TR10 is 10 mg per vial and 10 vials per pack, so the nominal pack sum is 100 mg. That pack sum is not the same listing as SKU TR100, which is 100 mg per vial and 10 vials per pack. TR5 is 5 mg × 10 vials (50 mg nominal pack sum). TR15 is 15 mg × 10 vials (150 mg nominal pack sum). Those pack totals are catalog arithmetic only.
The same editorial checklist before ordering is:
- 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.
- Review the matching batch records and confirm the 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 both the pack price and available stock. Editorial guidance notes that the product page shows the price of one listed pack, display currency follows the selected country, and checkout confirms the order total (per-vial size versus pack quantity).
Match the batch COA to the same SKU
A SKU identifies a listed product variant. A batch number identifies a batch record. Use both when locating a COA; a product name by itself is not enough when several sizes or batches exist (how to find a COA by SKU and batch).
Editorial verification guidance starts by matching product name, SKU, and batch number, then comparing certificate number and test date with the summary. 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. Published Tirzepatide COA records cited below also state that provider verification links were not independently fetched (how to verify a CertiPeptide COA).
A practical sequence from that guidance:
- Read the product and SKU from the product page or order documentation.
- Find the batch. 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 different size. A report for one SKU should not be used as evidence for another SKU merely because both are named Tirzepatide. An older published batch is not evidence of the batch that will be shipped next. A published report does not mean every order receives that batch; confirm the allocated batch separately. A missing public result is not automatically a failed test, and it is not a passed test either (how to find a COA by SKU and batch; how to verify a CertiPeptide COA).
Three published Tirzepatide batch records are cited below. Each record is for that batch only and is not evidence of clinical suitability or of every batch. Each lists the laboratory as Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group) and records test date 2026-08-25.
| Check | TR5 batch N9WA0PXCEF8Z | TR10 batch 0RMUIMVOKIST | TR15 batch 7HDJ0746WBN3 |

| Analyte | Tirzepatide TR5 | Tirzepatide TR10 | Tirzepatide TR15 |
| Appearance (Visual) | White loose powder; Pass vs White or almost white loose powder | White loose powder; Pass vs White or almost white loose powder | White loose powder; Pass vs White or almost white loose powder |

| Water content (Karl Fischer) | 4.7 %; Pass vs NMT 8.0 % | 4.9 %; Pass vs NMT 8.0 % | 5.3 %; Pass vs NMT 8.0 % |
| Bacterial endotoxins (LAL (gel-clot)) | <3 EU/mg; Pass vs NMT 10 EU/mg | <3 EU/mg; Pass vs NMT 10 EU/mg | <3 EU/mg; Pass vs NMT 10 EU/mg |
On all three records, gravimetric actual fill is above the nominal catalog size and is recorded as Pass against the listed specification. Those fill values are batch measurements, not a revised catalog size.
What the published records do not cover
Published batch records cited in this article cover TR5, TR10, and TR15 only. Listed SKUs TR20, TR30, TR40, TR50, TR60, TR80, TR100, and TR120 have catalog sizes on the product listing. A missing public result is not a failed test and is not a passed test.
Each COA scope statement applies only to the named batch. The records are not evidence of every future shipment, sterility, storage conditions, shipping performance, or clinical suitability. Appearance is a visual check of powder color and form, not a sterility determination. Endotoxin results are the recorded LAL (gel-clot) values with the qualifier <3 EU/mg against NMT 10 EU/mg. Unknown analytes are not shown as zero or absent.
When details differ, 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 (how to verify a CertiPeptide COA).
Verification checklist
- Product name is Tirzepatide and the SKU matches the intended vial size (for example TR5, TR10, or TR15).
- Nominal size unit is mg, and vials per pack is 10 for the listed variants.
- Pack-total milligrams are treated as label arithmetic, not as a COA fill result.
- Batch number and certificate number match the opened report.
- Test date, laboratory name, analyte (including the TR size), methods, units, qualifiers, and Pass determinations match the original record.
- The COA SKU is not borrowed from a different size.
- The batch allocated to the order is confirmed separately from any example published batch.
Frequently Asked Questions
Does a published Tirzepatide 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.
Can a TR5 COA be used as evidence for TR10 or another Tirzepatide size?
No. A report for one SKU should not be used as evidence for another SKU merely because both are named Tirzepatide. Match product name, SKU, and batch number.
How should 10 mg × 10 vials be read for Tirzepatide TR10?
It describes ten vials with a nominal size of 10 mg each, not a single vial containing 100 mg. The 100 mg pack sum is label arithmetic, not an analytical measurement. SKU TR100 is a different listing: 100 mg per vial and 10 vials per pack.
What if no public COA is listed for a Tirzepatide SKU?
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.
