How to use this reference list

These are the GHK-Cu citations and references for every quantitative claim in this digest. The inline markers throughout the site — [1], [2], and so on — correspond to the numbered entries below, which are listed on the page itself with full citations, PubMed or PubMed Central links and DOIs.

The list spans the foundational work (Maquart's 1988 collagen result, Pickart's tissue-remodeling and skin-regeneration reviews), the hair literature (the 45-patient ALAVAX trial, the C3H mouse study, the AHK-Cu analog work, the 2024 microemulsion and the 2026 short-peptides review), the gene-expression analysis, the human skin-penetration measurement, and the biomaterial wound-healing studies. Where a finding tested an analog (AHK-Cu) or a combination (5-ALA + GHK) rather than pure GHK-Cu, that is stated in the text, not buried — the citation tells you the molecule, and the body copy tells you the caveat.
