Overview of the published GHK-Cu study sources

The nineteen peer-reviewed publications indexed below span five decades of GHK and GHK-Cu research across four distinct experimental models, discussed across the home page, research timeline, effects balance, dosage context, benefits audit, and skin research review.

When reading the primary papers below, check the biological model in the title and abstract first: the 2006 laser resurfacing trial, the 2015 skin regeneration review, and the 2016 ALAVAX scalp trial cover human topical skin or scalp studies; the 2011 diffusion study and the 2025 anti-wrinkle delivery review cover excised human skin permeation and topical delivery barriers; the 1991 and 1997 and 2005 and 2015 and 2017 and 2020 papers cover living rodent models; and the 1988 and 2000 and 2008 and 2012 and 2018 and 2024 and 2025 cell-culture and bioinformatic papers cover cultured fibroblasts (including human COPD donor lung fibroblasts in 2012 and cultured fibroblasts from aged mice in 2024), in vitro biochemical assays, melanogenesis in A375 and B16 cells, and Connectivity Map gene-expression analyses.
