ghk-cu peptide clinical evidence Research Guide: Copper Overview and Laboratory Research GHK Cu Peptide | Clinical

Common side effects Injection-site reactions: mild redness, tenderness, swelling, occasional bruising - usually resolve within hours Skin flushing / warmth - brief, related to vasodilation Transient fatigue in the first 12 weeks of intensive protocols Mild headache - usually dose-related Higher-dose theoretical concerns Copper accumulation - each 2 mg injection adds roughly 0.03 mg of elemental copper, trivial next to the 0.92.2 mg from a normal diet

higher doses use more

These are short-chain peptides, typically just 2 to 4 amino acids in length, with molecular weights well under 1,000 Daltons
