Verifying TGF-DES means matching the listed SKU, the per-vial size, the pack quantity, and the published batch certificate rather than relying on the product name alone. The public catalog currently lists TGF-DES as SKU TGFDES2 at a nominal 2 mg per vial with 10 vials per pack. One published certificate, QC-2026-ZXERZM56LW, records results only for batch K05GAGP5X7DB on that SKU.
Confirm SKU TGFDES2, vial size, and pack quantity
A SKU identifies a listed product variant. A product name by itself is not enough when several sizes or batches can exist, so match the exact code before reading any certificate (How to find a COA by SKU and batch number).
On the TGF-DES product page, the publicly listed variant is TGFDES2. Catalog fields for that SKU are a nominal size of 2 mg per vial and 10 vials per pack (TGF-DES). The listing covers public listed variants only and is not a claim that the list is exhaustive.
Site editorial guidance treats per-vial size, vials per pack, and pack price as three separate fields. A description such as "2 mg × 10 vials" means ten vials with a nominal 2 mg each; it is not a single vial containing 20 mg. Any pack total is label arithmetic, not an analytical measurement. Actual fill and peptide-content values belong to the particular batch report (Per-vial size versus pack quantity).
| Field | Listed value for TGFDES2 |
|---|---|
| Product | TGF-DES |
| SKU | TGFDES2 |
| Nominal size per vial | 2 mg |
| Vials per pack | 10 |
| Nominal sum across one pack | 20 mg (label arithmetic) |
The 20 mg figure is only 2 mg × 10 vials. It is not a measured fill for any vial or pack.
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, then review matching batch records and confirm the order details. If a quotation or product documentation uses a different packaging description, ask support to reconcile it before relying on the calculation (Per-vial size versus pack quantity).
Read batch K05GAGP5X7DB only as that batch
A batch number identifies a batch record. Use both SKU and batch when locating a COA. A report for one size should not be used as evidence for another size merely because both share a product name, and an older published batch is not evidence of the batch that will be shipped next (How to find a COA by SKU and batch number).
The published TGF-DES record for batch K05GAGP5X7DB is tied to SKU TGFDES2 (2 mg) and certificate QC-2026-ZXERZM56LW. The listed laboratory is Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), and the recorded test date is 2026-04-08. These are published recorded results for this batch only. They are not evidence of clinical suitability or of every batch. Provider verification links were not independently fetched (TGF-DES — batch K05GAGP5X7DB).
Summary lines on that record:
| Report type | Recorded result |
|---|---|
| Identity | Conforms |
| Purity | 99.2 % |
| Weight | 2.40 mg |
| Endotoxin | <3 EU/mg |
The same certificate lists the following tests for analyte TGF-DES TGFDES2. Specifications, methods, units, and determinations are those recorded on the batch page:
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | Corresponds to theoretical mass | Conforms | Pass |
| Purity | HPLC | NLT 98.0 % | 99.2 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 90.4 % | Pass |
| Actual fill | Gravimetric | 2 mg | 2.40 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 4.8 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
HPLC purity (99.2 %) and HPLC peptide content (90.4 %) are separate recorded items. Gravimetric actual fill (2.40 mg) is not the same as the 2 mg catalog size. Bacterial endotoxins are reported as <3 EU/mg against a specification of NMT 10 EU/mg; that result is not a sterility determination.
A missing public result for another SKU or batch 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 (How to find a COA by SKU and batch number).
Verification sequence and evidence gaps
Editorial guidance for reading these records is to start by matching product name, SKU, and batch number, then open the original report and compare its certificate number and test date with the summary. Seeing a verification link alone does not prove that a report is currently valid. A verification page may require an account with the report provider (How to verify a CertiPeptide COA).
Checklist for TGF-DES TGFDES2:
- Read TGF-DES and SKU TGFDES2 from the product page or order documentation (2 mg per vial, 10 vials per pack).
- Find the batch. The published example is K05GAGP5X7DB. If the allocated batch is not stated, ask support to confirm it.
- On the batch page, check certificate QC-2026-ZXERZM56LW, sample identity TGF-DES TGFDES2, test date 2026-04-08, and the listed laboratory.
- Open the original report and compare values and units with the summary, including 99.2 % HPLC purity, 90.4 % peptide content, 2.40 mg actual fill, and <3 EU/mg endotoxin.
- 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 of a certificate is useful for comparison, but the original document and provider record are stronger verification evidence (How to verify a CertiPeptide COA).
A published report does not mean every order receives that batch; confirm the batch allocated to the order separately. The site does not independently confirm the current status of a login-protected provider record.
Frequently Asked Questions
Which TGF-DES SKU, vial size, and pack quantity are publicly listed?
The public TGF-DES listing currently includes SKU TGFDES2, with a nominal size of 2 mg per vial and 10 vials per pack. That list is limited to public listed variants and is not a claim that every possible pack is shown.
What does the published COA for batch K05GAGP5X7DB cover?
Certificate QC-2026-ZXERZM56LW records results only for TGF-DES SKU TGFDES2, batch K05GAGP5X7DB, tested 2026-04-08 by Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group). It is not evidence of every batch or of clinical suitability.
How should 2 mg × 10 vials be read?
Read per-vial size and vials per pack as separate fields: ten vials with a nominal 2 mg each, not one vial of 20 mg. Any pack total is label arithmetic, not an analytical measurement; actual fill belongs to the batch report.
Does a published TGF-DES report 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.
