Common questions about GHK-Cu
Is Pepdor's GHK-Cu independently tested?
Yes. Beyond the batch-verification HPLC COA on every batch, 2 independent third-party lab tests are published unedited in the public Test Ledger. Results are posted as received, whatever they show.
What purity is the current GHK-Cu batch?
Current batch GH-2606-B (COA Jun 18, 2026) measured 99% by batch-verification HPLC, with independent third-party tests averaging 98.9%. Full history for every batch, including archived ones, stays public.
What documentation ships with GHK-Cu?
Every vial carries its batch number and links to a published COA (batch-verification HPLC; LC-MS identity, endotoxin, and sterility shown per batch where tested). 50 mg: $22 per vial; 100 mg: $35 per vial. Sourced direct from the synthesis facility.
How do I verify a GHK-Cu batch before ordering?
Every vial label carries its batch number (currently GH-2606-B). Look the batch up in the public Test Ledger or the machine-readable feed at pepdor.com/ledger.json to see the COA and all independent test results before ordering.
How should GHK-Cu be stored?
Lyophilized: store at 2-8 °C, ~18 months. In solution (2-8 °C), protect from light; solution stability varies with solvent and handling. Solution is naturally blue - that is the copper complex, not a dye.
