Pickart and colleagues reported in Nature (1980) that the tripeptide facilitates copper uptake into cultured cells, and potentiometric titration places the GHK-Cu stability constant at log K of approximately 16.4, marginally above the copper transport site of human serum albumin at roughly 16.2

Benefits Epithalon + GHK-Cu is believed to help with: Multi-pathway longevity support: Epithalon has been reported in cell, animal, and early human studies to extend telomeres, improve aging biomarkers, support melatonin output, and potentially reduce age-related mortality, though data remain preliminary and largely from Russian cohorts. Deeper rest and circadian balance: By acting on pineal cells and melatonin pathways, Epithalon may help resync sleepwake cycles and nighttime recovery, which Better Med Spa amplifies with sleep hygiene and lightexposure coaching. Collagenrich, firmer skin: GHKCu has been shown to increase collagen and elastin production, enhance dermal matrix organization, accelerate wound healing, and visibly improve wrinkles and texture in topical and injectable studies. Youthful gene signaling: GHKCu can shift thousands of genes toward a more youthful expression profile, including antioxidant, anti-inflammatory, and regenerative pathways, complementing Epithalons broader geroprotective effects. Holistic protocol design: At Better Med Spa, Cellular Reset is integrated with labs, recovery rituals, and KBeauty facials so clients feel and see the impactfrom deeper sleep to more luminous skin and resilience.

(Neither the FDA nor HHS responded to ProPublicas requests for more information.) But several regulatory shortcuts exist and, ultimately, Kennedy could simply declare the ingredients are legal
