Copper-binding tripeptide complex for laboratory research.
GHK-Cu is a copper-binding tripeptide complex composed of glycine, histidine, and lysine coordinated with copper. Scientific literature discusses it in relation to extracellular matrix research, copper-peptide biology, gene-expression models, and tissue-remodelling pathway studies.

Upon receiving the lyophilized peptide, store it at 4 °C or colder and away from bright light. Lyophilized peptides are stable at room temperature for weeks, but for longer-term storage, it is safer to store them at -20 °C or colder. Exposure to moisture can greatly decrease long-term stability. Before opening a container stored in cold conditions, allow it to equilibrate to room temperature first to reduce moisture uptake from the surrounding atmosphere.
Peptides in lyophilized form are supplied in glass vials by standard shipping methods and do not require refrigeration. Short-term temperature fluctuations during transport do not reduce their quality or stability. Even at high summer temperatures, peptides in lyophilized form remain stable for several weeks.
The shelf life of peptide solutions is limited. Freezing aliquots can help prolong storage life. In general, peptide solutions are commonly stored for around 3 or more weeks at +4 °C and around 3-4 months at -20 °C. Avoid repeated freeze-thaw cycles, as this can degrade peptides.
Research use only. For lawful laboratory research and analytical use where permitted by law. Not for human or animal use.
