GHK-Cu is primarily used for skin regeneration, wound healing, and anti-aging

Research examines downstream signaling and metabolic-pathway responses rather than a confirmed receptor interaction

Anti-aging and longevity peptides Epithalon: Standard shelf life: 28-30 days refrigerated Maximum: 30-35 days Short peptide sequence, stable Thymosin Alpha-1: Standard shelf life: 28-30 days refrigerated Maximum: 45 days (pharmaceutical grade) Relatively stable peptide Semax and Selank: Standard shelf life: 28-30 days refrigerated Maximum: 30-35 days Short peptides, stable Sexual health peptides PT-141 (Bremelanotide): Standard shelf life: 28-30 days refrigerated Maximum: 45 days (pharmaceutical Vyleesi) Stable peptide Melanotan II: Standard shelf life: 28-30 days refrigerated Maximum: 35-40 days Relatively stable Copper peptides (GHK-Cu) GHK-Cu injectable: Standard shelf life: 28-30 days refrigerated Maximum: 30 days (copper can catalyze oxidation) More sensitive than other peptides due to copper ion Special note: Copper peptides may show visible degradation (color change to greenish/blue) if stored too long
