Gastric acid resistance explained The human stomach maintains a pH between 1.5 and 3.5
Unused GHK-Cu needles syringes should be stored in their original, unopened sterile packaging in a clean, dry environment, away from direct sunlight and extreme temperatures
Common side effects include pain or redness at the injection site, mild diarrhea, itching, and swelling
First isolated from human plasma, GHK-Cu is one of the most extensively studied peptides in published research literature, frequently referenced in models exploring skin biology, collagen and elastin signalling, gene expression modulation, and extracellular matrix remodelling pathways
Its formulation ensures peptide stability, high purity, and reproducible activity under recommended storage conditions
