GHK-Cu (Gly-His-Lys copper complex) is a tripeptide with high Cu²⁺ affinity, studied in extracellular matrix modeling, tissue repair, and angiogenesis research. Each lot undergoes HPLC and MS characterization -- ≥99% purity, verified

Buying cheap, untested peptides means you're injecting unknown compounds that may not work or could be contaminated

Choose:Hyaluronic Acid

Factors that accelerate expiration Temperature fluctuations: Repeated freeze-thaw cycles very damaging Each thaw = period of degradation One freeze-thaw: Minor impact Multiple cycles: Significant loss of potency Keep frozen continuously until ready to reconstitute Light exposure: UV and visible light degrade peptides Some peptides more photosensitive (GHK-Cu) Amber vials protect partially Keep vials in boxes or dark storage Air exposure: Oxygen causes oxidation Minimize time vial is open Don't store without cap Use quickly after reconstitution Moisture exposure (for powder): Even atmospheric humidity can start degradation Keep in sealed vials always Don't open unnecessarily Store in dry environment Contamination: Non-sterile technique introduces bacteria Bacterial enzymes destroy peptides rapidly Always use alcohol wipes Never touch rubber stopper Use bacteriostatic water to inhibit growth pH extremes: Some peptides unstable at wrong pH Reconstitute with appropriate solution Bacteriostatic water usually optimal (slightly acidic) Don't mix with other substances without knowledge Shelf life before reconstitution (lyophilized powder) How long dry peptides last in different conditions

Mild elution conditions preserve protein antigenicity and function
