Commonly used via injection or oral forms depending on protocols
The peptide completed six randomized, double-blind, placebo-controlled clinical trials involving over 900 participants, establishing excellent safety and tolerability
The copper content of GHK-Cu formulations has been a theoretical safety consideration, given that excessive copper can be toxic - however, the amounts used in cosmetic and research applications are extremely small, the copper is tightly chelated by the peptide (reducing free copper availability), and topical absorption of copper from these products appears minimal and well below levels that would cause systemic copper accumulation or toxicity
Theyre also more accessible, with fewer regulatory restrictions compared to traditional HGH
Folate deficiency can have serious side effects, so treatment (especially during early pregnancy) is important
