How do I evaluate a GHK-Cu copper peptide retailer?

Request the batch-specific COA and verify it against an independent reference. Confirm the supplier positions products as research-use-only. Legitimate research retailers accept credit cards and provide storage guidance.

Does the copper form matter for GHK-Cu research?

Yes. The copper ion is essential to GHK-Cu's gene-regulatory activity. Verify that the compound is specifically GHK-Cu (glycyl-L-histidyl-L-lysine copper II) and not a generic copper peptide complex. Copper loading should be stoichiometric.
