It's generally recommended to avoid layering GHK-Cu with highly acidic ingredients like L-ascorbic acid (Vitamin C) or potent retinoids in the same session, as this can reduce efficacy or increase irritation

Introduction: Introduction: AOD-9604 is a synthetic peptide fragment of human growth hormone (hGH 177191) engineered to replicate hGHs fat-metabolism effects without altering IGF-1 or glucose levels. In preclinical research, it promoted lipolysis (fat breakdown) and reduced lipogenesis (fat storage) through receptor-independent mechanisms. AOD-9604 Fast Facts Class: Synthetic hGH fragment analog (Tyr-hGH 177191) Intended purpose: Stimulate fat metabolism while avoiding hGHs growth or glucose effects Mechanism: Increases fat oxidation, enhances lipolysis, suppresses lipogenesis Distinct from hGH: Does not activate the growth hormone receptor or raise IGF-1 Development stage: Completed Phase II trials
The peptide is also studied for its effects on melatonin synthesis regulation and circadian rhythm normalization in aged experimental models
Some individuals may experience mild injection-site reactions (e.g., redness, swelling) or occasional headaches
