GHK-Cu vs BPC-157: research comparison
GHK-Cu and BPC-157 are both present in the BioLabs Research catalog but represent unrelated chemical identities. GHK-Cu is a copper(II)–tripeptide complex; BPC-157 is a pentadecapeptide. Comparing them is useful for procurement clarity, not because they share a pathway label in marketing copy.

GHK-Cu
GHK-Cu (CAS 89030-95-5) is listed with formula C14H22CuN6O4 and approximate MW ~403.9 Da on site identity strips. The copper complexation is part of the identity — a copper-free GHK listing would be a different reagent. Research literature often places GHK-Cu in extracellular matrix and copper-handling model systems.
See GHK-Cu copper peptide research and GHK-Cu product. GLOW 70 is a separate named blend SKU that should not be confused with neat GHK-Cu.
BPC-157
BPC-157 (CAS 137525-51-0) carries formula C62H98N16O22, MW ~1419.5 Da, and sequence GEPPPGKPADDAGLV on this site. It contains no copper center. Analytical expectations (HPLC, MS) differ from metal–peptide complexes; treat COA methods accordingly.

Key differences
- Metal complex (Cu) vs non-metallated pentadecapeptide.
- Different CAS, formula, MW, and sequence.
- Distinct research literature clusters; not drop-in replacements.
- Both sold as separate catalog vials with their own strength options.

Copper–peptide handling may involve additional laboratory safety notes versus plain peptides; follow SDS guidance for metal-containing reagents. For hosted COAs on other SKUs, filter the COA Library.
Word-of-mouth blend names (for example GLOW 70) can include multiple components — always open the product identity strip rather than assuming “GHK-Cu equivalent.”
