But if you choose to share something exciting, that's great

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

Particular focus could be devoted to thioredoxins (and enzymes involved in its synthesis and redox pathways) and NADPH (with the enzymes involved in NADPH biosynthesis)
