How to read this GHK-Cu reference list

Every quantitative claim on this site maps to one of the numbered studies below. The list is anchored by the canonical reviews (Pickart 2008, 2015, 2018) and the primary experimental papers behind the headline numbers: the picomolar collagen dose-response [1], the copper-dependence of MMP-2 induction [3], the hyaluronic-acid collagen IV synergy [4], the 45-patient hair-count trial [7], the skin-penetration and dermal-depot measurements [9], the liposomal elastase data [10], and the 2025 anti-wrinkle delivery review [15]. Where a study used the free GHK peptide or a close analog (AHK-Cu) rather than the copper complex, that is flagged in the text on the page that cites it, because the form used changes how far the conclusion travels.
