For all protocols, sourcing quality peptides is fundamental
The dose is deliberately high compared to classical peptides (5-10 mg for GLP-1 analogues, 2-5 mg for short regeneratives) because documented GHK-Cu protocols use larger quantities in trichological and cutaneous research (1-3 mg per injection, concentrated topical applications)
Its small molecular weight (~400 Da) supports transdermal penetration through scalp skin
Its stability in vitro is limited, with a half-life of roughly 15 minutes, but in vivo it may form complexes with carrier proteins or exist as part of a larger precursor molecule to resist degradation
Studies based on diet-induced changes in serum UA levels showed that UA may have protective effects on the risk of PD
