What differs at the molecular listing
GHK-Cu (89030-95-5) is catalogued as a copper tripeptide: Copper(II) complex of Gly-His-Lys. Matrix and copper-binding research listing — not a finished cosmetic.
ECM-70 (Lot label / COA) is catalogued as a named blend: Named catalog blend. This page does not invent a peptide recipe or ratio.
CAS, fragment length, and salt form are not interchangeable. Read the sequence or identity line printed for the lot. This table does not rank listings or name a study design.
Catalog questions
Are GHK-Cu and ECM-70 the same catalog identity?
No. GHK-Cu is listed as CAS 89030-95-5 and ECM-70 as CAS Lot label / COA. Sequences, salt form, and fragment length are identity-critical. Confirm the lot label.
What listed strengths appear in the catalog?
GHK-Cu is listed at 100mg. ECM-70 is listed at 70mg. Listed strengths are catalog sizes. GHK-Cu: Lab COA — view PDF; ECM-70: Lab COA — view PDF.
Where do lot and COA documents live?
Lab COA PDFs are published per product in our COA library; SDS sheets are available to download. Open the product page Request lot docs control or use Contact. This compare table lists catalog identity only, not purity results.
Does this page name a laboratory method?
No. The table is limited to catalog identity, public registry identifiers, listed form, and listed strengths. Method, solvent class, and handling belong on the lot papers and the institutional SOP.
Are these listings for laboratory research only?
Yes. Both SKUs are research-use-only reagents for in-vitro and analytical work. They are not medicines, supplements, or veterinary products.
All discussion on this page is limited to chemical identity, public registry identifiers, and laboratory research framing. BioLabs Research lists reagents for in-vitro and analytical work only. Confirm listed strengths on the product page. To request a lot, use Contact.
