Topical GHK-Cu serum shelf life Pre-made commercial serums: Usually 6-12 months unopened 3-6 months after opening Check manufacturer recommendations Refrigerate after opening extends life DIY serums (mixing powder with carrier): Shorter shelf life than commercial 2-4 weeks typical (no preservatives) Must refrigerate Discard if color changes Factors affecting topical shelf life: Preservatives: Extend significantly pH: Neutral pH more stable Carrier: Some better than others (hyaluronic acid, glycerin good) Storage: Cool, dark, sealed Contamination: Sterile technique critical Best practices for topical GHK-Cu: Buy small bottles (use within 3-6 months) Refrigerate after opening Don't double-dip (pour into hand, don't touch dropper to skin) Watch for color changes (brown = oxidized) Replace every 6 months even if looks fine See our how to reconstitute peptides , bacteriostatic water for peptides , and how long reconstituted peptides last in fridge
If you do not have a FDA-cleared sharps disposal container, you may use a household container that is: Made of heavy-duty plastic, Can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out, Upright and stable during use, Leak resistant, and Properly labeled to warn of hazardous waste inside the container
Each component targets a distinct aspect of dermal health: TB-500 promotes cell migration and new blood vessel formation, BPC-157 drives repair signalling and growth factor expression, and GHK-Cu shown to influence approximately 4,000 genes supports collagen synthesis, antioxidant defence, and extracellular matrix remodelling
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring peptide complex that plays a role in various biological functions and has become a significant focus within peptide research
