GHK-Cu is a synthetic tripeptide–copper complex composed of glycine, histidine, and lysine bound to a copper ion. It functions through high-affinity peptide–metal interactions, enabling targeted signaling pathways relevant to cellular activity and molecular stability. Commonly utilized in research settings to study tissue dynamics, regenerative signaling, and biochemical response mechanisms. Supplied by Peptico for research-use only.

Handling
Utilize appropriate sterile technique and controlled environments during preparation.
Short-Term Storage - Lyophilized Powder Form Only
- For maximum potency, lyophilized materials may generally be stored between 2°C and 8°C (36°F to 46°F) for up to 4 weeks when maintained in their original, sealed lyophilized form.
- Maintain a cool and dry environment.
- Protect from moisture and light.
- Minimize exposure to humidity and temperature fluctuations.
Long-Term Storage - Lyophilized Powder Form Only
- For maximum potency and long-term preservation, lyophilized materials may generally be stored between -20°C and -80°C (-4°F to -112°F) for up to 1 year when preserved in their original, sealed lyophilized form.
- Maintain a cool and dry environment.
- Protect from moisture and light.
- Minimize exposure to humidity and temperature fluctuations.
Important Note:
Storage guidelines apply only to lyophilized material in its original, sealed, and untampered vial.
COA History
All shipped products include a unique batch number printed on the vial label. This batch number corresponds to a third-party Certificate of Analysis tested by an ISO/IEC 17025 accredited laboratory.
The COA attached at the top of this page, along with the COA marked “Current” below, represents the active production batch currently being shipped. This same batch number will appear on the label of your vial.
For previous purchases, please refer to COAs marked “Historical” and match the batch number on your vial to the batch number listed on the corresponding COA.
For a complete record of testing documentation across all products and batches, please visit our COA Vault, which includes both current and historical COAs.
