concurrent tobacco smoking further augments thrombotic risk, and careful monitoring is advised when estrogens are co-administered with thyroid hormones, corticosteroids, or anticoagulants due to possible alterations in binding protein levels and pharmacodynamic response
Dosing Protocols in Research Most gene expression studies used GHK-Cu at concentrations equivalent to: Subcutaneous injection: 12 mg/day (common biohacking protocol) Topical application: 15% concentration creams/serums (skin-focused gene effects) In vitro concentrations: 10100 nM range in cell studies For subcutaneous use, peptide community protocols typically run: Dose: 12 mg/day Cycle: 3090 days on, 30 days off Injection site: Subcutaneous, rotating sites Common stack: GHK-Cu + BPC-157 (synergistic tissue repair), GHK-Cu + MOTS-C (longevity stack), GHK-Cu + Retatrutide (body recomposition with connective tissue support) Topical use is effective for skin-specific outcomes
