When you compare peptide blends, treat the listed product name, SKU, pack layout, and batch certificate as separate records. A blend is not an interchangeable alias for its ingredients, and a certificate issued for one size or lot does not document another. The pages cited here are site editorial guidance on how to read those records, not independent scientific evidence of identity, purity, fill, or performance.
Catalog specifications are not batch measurements
Site listings describe how a variant is packed and priced. They are not a substitute for a batch report. Read the per-vial size, vials per pack, and pack price as three separate fields, as explained in the guide to per-vial size versus pack quantity. A product 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.
For a blend, check whether the stated size is combined and read the separate ingredient information. That check belongs with the catalog fields. Do not assume that one ingredient’s listing can stand in for the blend.
In that same SKU example for Retatrutide (SKU RT10), the listed values are a nominal size of 10 mg per vial, 10 vials per pack, and a nominal sum of 100 mg across one pack. The sum is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report.
Price follows the listed pack, not a homemade total. The product page shows the price of one listed pack. Selecting a different SKU can change both the pack price and the available stock. The SKU table keeps each size and pack quantity next to its own price. Display currency follows the selected country. Checkout confirms the order total, shipping, and any applicable discount. A saved screenshot can become outdated when prices or availability change.
If a quotation or other product documentation uses a different packaging description, ask support to reconcile it before relying on the calculation.
Find the COA with SKU and batch, not the blend name alone
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, according to the guide on finding a COA by SKU and batch.
Compare four identifiers:
| Identifier | What to compare | Worked example in the guide |
|---|---|---|
| Product | Exact product or blend name | Retatrutide |
| SKU | Listed size and pack variant | RT10 |
| Batch | The batch in the document | R3Y0BM87SYEP |
| Certificate | The particular issued report | QC-2026-CMJBJX7R8G |
Those example values from the SKU and batch guide illustrate how identifiers line up on the site. They are not a substitute for opening the matching certificate for the SKU and batch you are actually comparing.
Open the product page, select the SKU, and read the matching certificate panel. Selecting a SKU updates the report without moving your viewing position. The SKU table also provides a direct link that selects the variant. The report library supports search and page-by-page browsing. Open a batch’s fixed page to share its results with a colleague, and match the original document before relying on it.
Two mismatches come up often. A report for RT5 should not be used as evidence for RT10 merely because both say Retatrutide. Likewise, an older published batch is not evidence of the batch that will be shipped next.
Blends need the same discipline, with one extra rule. Blends are separate products, not interchangeable aliases for their ingredients. Use the complete blend name and SKU. Individual ingredient results may appear as separate rows in the report.
When a report 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.
Checklist: compare listings before you compare numbers
Use this sequence whenever two blend pages, quotes, or certificates look similar.
- Match the exact product or complete blend name—not an ingredient alias.
- Match the exact SKU (listed size and pack variant).
- Check the per-vial size and unit.
- Check the number of vials per pack, separately from any pack-total arithmetic.
- For a blend, check whether the stated size is combined and read the separate ingredient information.
- Treat pack price as the price of one listed pack for that SKU; do not reuse an outdated screenshot.
- Open the certificate panel for that SKU and read the batch number on the document.
- Match the particular issued certificate, not only the product name.
- If ingredient rows appear on the blend report, read them as rows for that blend SKU and batch—not as standalone products.
- If the public report is missing or a shared link is gone, ask support for the exact SKU and batch instead of substituting another record.
The cited pages are site editorial guidance on how to read product and batch records. They are not independent scientific evidence of identity, purity, fill, or performance, and they do not fill gaps where a matching certificate has not been opened.
Frequently Asked Questions
Should I treat a blend as the same product as one of its ingredients?
No. Blends are separate products, not interchangeable aliases for their ingredients. Use the complete blend name and SKU. Individual ingredient results may appear as separate rows in the blend report.
Does a pack total such as 100 mg mean content was measured at 100 mg?
No. In the RT10 listing example, 10 mg per vial and 10 vials per pack give a nominal sum of 100 mg. That sum is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report.
Can I use another size’s COA if the peptide name matches?
No. A report for RT5 should not be used as evidence for RT10 merely because both say Retatrutide. A SKU identifies the listed variant and a batch number identifies the batch record; use both when locating a COA.
What does a missing public COA mean?
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. If a previously shared report link is no longer available, ask for the current documentation rather than substituting a different batch.
