Identify the named compound
GHK-Cu and AHK-Cu are separate catalog materials. Bluum names the GHK complex as copper tripeptide-1. The AHK listing identifies the alanine–histidine–lysine material. Use the exact name specified by your laboratory.
Compare like with like
Price, vial size and the presence of a lot document can be compared as purchasing features. A lower price or a shared copper-peptide category does not demonstrate equivalent identity or suitability for a protocol.
Keep the analytical records separate
The GHK-Cu example linked here identifies lot DPS-5065007. The AHK-Cu record has a different lot and different analytical results. Preserve those distinctions rather than applying either result to all copper peptides.
Confirm the form at the destination
Both a compound name and a physical format belong on a purchase specification. Confirm the selected Bluum listing and lot documentation before ordering; do not treat a finished topical formula as the same offer as a research vial.
