Step-by-step reconstitution process Supplies needed: 50mg GHK-Cu vial (lyophilized powder) 5ml bacteriostatic water 3ml or 5ml syringe Alcohol wipes Reconstitution steps: Clean workspace Wash hands thoroughly Wipe vials with alcohol Draw bacteriostatic water Draw 5ml into syringe Remove air bubbles Add water to GHK-Cu Insert needle through rubber stopper Slowly inject water down side of vial (not directly on powder) Aim stream at glass wall, not powder Let dissolve Remove syringe Swirl gently (don't shake) Let sit 1-3 minutes Swirl again until completely clear Inspect solution Should be clear (slightly blue tint normal) No particles or cloudiness If not clear, swirl more Label vial Write concentration (10mg/ml) Write date reconstituted Write expiration (30 days) Refrigerate immediately Store at 2-8C Protect from light Use within 30 days See our peptide storage guide , how long reconstituted peptides last in fridge , and lyophilized vs liquid peptides

Safety of Administering B12 Injections at Home For those considering self-administering B12 injections at home, safety is a paramount concern
Free Cu2+ is toxic (Fenton reactions, hydroxyl radicals), but the GHK-Cu complex is stable, diffusible and delivers copper in a targeted manner to copper-dependent metalloenzymes: lysyl oxidase (collagen/elastin crosslinking), Cu/Zn superoxide dismutase (SOD1, antioxidant defence), tyrosinase (controlled melanogenesis), dopamine-beta-hydroxylase
Our Nurse and our GPs can administer these injections
