GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring tripeptide-copper complex found in human plasma, saliva, and urine. It consists of the tripeptide Gly-His-Lys chelated to a copper (II) ion. GHK-Cu has been the subject of substantial research interest due to its presence in biological fluids and its interactions with a broad range of biological processes at the cellular level. Heartland Bio Labs supplies GHK-Cu as a lyophilized research compound of verified purity.

How should I store this peptide?+

Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.

What should I reconstitute it with?+

Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.

How quickly do orders ship?+

Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.

Is the COA verified independently?+

Yes. Every lot is tested by HPLC for purity (target ≥99%) and mass spectrometry for molecular identity before release. The COA is generated from the actual lot data, not a generic template.

Can I get bulk or institutional pricing?+

Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
