pmc4508379 ghk-cu (Copper Peptide) | Research Peptide GHK-Cu Before & After: Results

I recommend a high-grade Methylation supplement

Its binding constant (pKa 16.44) is similar to albumin's copper transport site (log = 16.2), allowing GHK to exchange copper with albumin for intracellular delivery.[3] Discovery and design rationale GHK was first identified in 1973 in fractions of human plasma that promoted survival of liver cells in culture

Key Takeaway: While IM injections are effective, liposomal oral delivery offers a non-invasive way to achieve high bioavailability by protecting the glutathione from digestion

Not recommended for individuals with known sensitivity to copper-based compounds
