ECM-70 is a named catalog blend. It is not a CAS number. A trade name on a vial does not mint a registry substance. Until a lot certificate of analysis lists the component molecules โ names, sequences or formulas, and masses โ the listing is a name. This article will not invent those components. Cellular-matrix / ECM work still needs that named list; the trade name is not a matrix recipe.
The live product page for ECM-70 on this site does not publish component peptides. That silence is the identity story. Other blend SKUs on the same catalog do name both molecules. Those are different listings. Do not copy their recipes onto this one.
Trade-name blends do not get a CAS
CAS registry numbers index defined substances. A house blend name โ GLOW, a number, a marketing token โ is not a defined substance. Assigning a fake CAS to a trade name, or borrowing a CAS from a peptide that might be in some other shop's glow mix, is a labeling failure. The correct CAS line for an unnamed blend is: none, pending the component list.
| Listing type | What identity looks like | CAS |
|---|---|---|
| Single peptide (example: KPV) | One sequence, one mass, one public CAS | Yes โ the molecule's CAS |
| Named two-molecule blend | Two sequences, two masses, both printed on the PDP | Two CAS numbers; no third CAS |
| Trade-name blend (ECM-70) | Name on the carton; components only if the lot docs list them | No CAS for the name |
If a vendor prints a single CAS on an ECM-70 label, ask which molecule that CAS belongs to, and where the other components are. If they cannot answer, you do not have identity.
Identity is the lot docs component list
For a named blend, the only document that can turn a name into chemistry is a set of lot docs that lists each component: name, sequence or formula, theoretical mass, observed mass, and โ if the work is quantitative โ how much of each is in the cake. HPLC area% of the blend peak is not that list. A storefront graphic is not that list. A blog article is not that list, including this one.
Until that paper exists, a receiving lab should log ECM-70 as a named SKU with identity pending, not as a sequence. Do not write a methods section that pretends the vial is a known peptide. Do not copy a competitor's blend recipe into your notebook and call it this catalog's lot.
Contrast with blends that name both molecules
This catalog has blend SKUs that do the honest thing and print both chemicals:
- BPC-157 / TB-500 blend โ two sequences, two masses. Identity note: two sequences, two masses.
- Tesamorelin / ipamorelin โ two CAS numbers on one vial. Identity note: two CAS numbers.
Those pages can be checked against public registries before the lot arrives. ECM-70 cannot, because the live PDP does not publish the components. That is not a gap this article will fill with a guess.
What this article will not invent
It is common, on other storefronts, to see GLOW used as shorthand for a GHK-Cu plus BPC-157 plus TB-500 mix, or some other trio. This article does not assert that mix for biolabsresearch.co. It does not assert any other mix. The live PDP does not publish component peptides. Inventing GHK-Cu + BPC-157 + TB-500 (or any other recipe) would be a false identity statement.
If future lot docs name components, those names belong to that lot. They still do not become a CAS for the trade name. Another lot could differ. File COAs by lot number, not by the word GLOW.
Request the COA
The practical action is to request the lot certificate of analysis and to refuse to treat the SKU as a defined mixture until the component list is on paper. The catalog page is ECM-70. Ask for lot number, component names, sequences or formulas, observed masses, and the HPLC method. If the reply is a brand story without those lines, you still have a name, not a chemical identity.

What belongs in a purchasing file
Record the SKU name, the URL of the live PDP, the date you checked that the PDP still does not list components, and the COA request. If a COA later arrives, file it under the lot number and quote its component table verbatim. Do not back-propagate that table onto older lots. Do not print it on this blog as if it were the definition of ECM-70.
A trade name is not a CAS. Identity is the lot docs component list โ cellular matrix / ECM work still needs named molecules.
