Evidence for a major role of heredity in Graves disease: a population-based study of two Danish twin cohorts
IV Site Irritation: Rarely, irritation or infection at the IV site can contribute to feeling unwell
Providing the closely interrelated increased pressure in the three body cavities interacting with each other rapidly transmitted through the venous system [28,29] (and thereby, venous system as therapy target [20,21,22,23,24,25,26,27]), the occluded superior sagittal sinus in addition to the brain swelling and lesions and increased pressure in the superior sagittal sinus may induce a comparable deadly syndrome

From topical research: Most commonly reported observation: mild transient redness at application site (attributed to vascular activity from VEGF stimulation) No systemic adverse events reported in human topical studies at standard concentrations No evidence of carcinogenicity or mutagenicity in available in vitro models From injectable research (preclinical): At supratherapeutic doses in animal models, mild injection site reactions have been noted No organ toxicity observed in standard preclinical safety panels No immunogenicity concerns identified (consistent with its endogenous structure) Copper considerations: GHK-Cu delivers a small amount of bioavailable copper
