What Topical Does Well Published research documents topical GHK-Cu's effects in three primary areas: Wrinkle and fine-line reduction -- consistently documented across multiple facial and eye-area studies Collagen and extracellular matrix stimulation -- increased synthesis of collagen, elastin, glycosaminoglycans, and decorin in treated skin Post-procedure recovery -- accelerated healing documented in post-laser resurfacing protocols The limitation is equally clear: topical delivery confines the peptide's activity to the skin
In the second step, glutathione synthase (GS) catalyzes the addition of glycine to -GC, yielding GSH
Peptides are short chains of amino acids that act as targeted messengers in the bodyimproving sleep, metabolism, immunity, cellular repair, fat loss, and even collagen production

These appear to be dose-dependent and typically resolve with dose reduction
