Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.

A Systematic Review of the Mechanisms and Therapeutic Applications of GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper Complex) in Topical Microneedle Delivery: A Case for Expanded Clinical Trials
GHK-Cu, the copper-bound form of the human tripeptide glycyl-L-histidyl-L-lysine has accumulated more than four decades of pre-clinical evidence for tissue regeneration, anti-inflammatory action, antioxidant capacity, and broad gene-expression remodeling.

Background/Objectives : Glycyl-L-histidyl-L-lysine (GHK) and its copper(II) complex GHK-Cu have been studied for matrix remodeling, inflammation, redox regulation, angiogenesis, and tissue repair, yet the literature frequently treats GHK-Cu as a single active ingredient despite formulation-dependent variation in coordi…

Systemic and Topical Geroprotective Rejuvenation Assessed by START/REST Aging Clocks
This study tests whether certain medicines and a skin treatment can slow down or partly reverse the body's aging process. As people age, the activity of their genes changes in predictable ways. Researchers can now measure a person's "biological age" from these gene-activity patterns in skin and blood.

Topical and nutricosmetic products for healthy hair and dermal antiaging using "dual-acting" (2 for 1) plant-based peptides, hormones, and cannabinoids
One of the side effects of oral antiaging retinoids is increased hair shedding. Retinoids promote the expression of TGF-β2 from fibroblasts, which stimulate collagen expression but silences keratinocytes.
