The short answer

What is GHK-Cu?

GHK-Cu is a copper peptide: the tripeptide glycyl-L-histidyl-L-lysine bound to a copper ion, found naturally in human plasma at a concentration that falls by roughly 60 percent between age 20 and 60. In cell studies it acts as a signaling molecule that stimulated fibroblast collagen production at very low concentrations (Maquart et al., 1988), and reviews describe it as an anti-aging peptide that modulates a broad set of genes involved in skin repair (Pickart and Margolina, 2018; Dou et al., 2020). Its strongest human evidence is topical: 12-week trials of topical GHK-Cu reported denser, firmer skin with reduced line depth (Pickart and Margolina, 2018). There is no large, trial-validated systemic human dose, so what ships here is a research-grade 100mg vial and a reference to the ranges published studies used, not a dose for any individual.

The Science

Multi-Pathway Skin Renewal

GHK is a tripeptide found in human plasma whose concentration falls roughly 60 percent between age 20 and 60. Bound to copper it acts as a signaling molecule, and the published work describes it stimulating fibroblast collagen production at very low concentrations (Maquart et al., FEBS Lett 1988, PMID 3169264).

Copper Delivery

GHK binds copper at physiological pH and delivers it to cells where lysyl oxidase uses it to cross-link new collagen.

Fibroblast Activation

Upregulates over 4,000 genes including collagen, elastin, and decorin synthesis, the structural foundation of skin.

Anti-Inflammatory

Reduced inflammatory gene expression (TNF-alpha, IL-6, NF-kB) is among the described mechanisms in the published work.

Applications

Common Use Cases

Anti-Aging Skin Renewal

Line depth, firmness, elasticity and tone were the endpoints the 12-week topical trials measured.

Wound and Scar Repair

Post-procedure healing, scar fading, and accelerated tissue repair after cuts or burns.

Hair Density Support

Hair-follicle effects are a studied research area, on a thinner evidence base than the skin work.

Post-Procedure Recovery

Post-procedure wound-healing models, including after resurfacing and surgery.

Research Timeline

What the studies measured, and when

Research timeline

What the studies measured, and when

In vitro

GHK-Cu stimulated collagen production in human fibroblasts at very low concentrations (Maquart et al., FEBS Lett 1988, PMID 3169264).

12-week trials

Human trials of TOPICAL GHK-Cu measured skin over about 12 weeks and reported denser, firmer skin with reduced line depth (Leyden et al. and Abdulghani et al., summarized in Pickart and Margolina, Int J Mol Sci 2018, PMID 29986520).

Head to head

In one 12-week comparison, collagen production improved in more treated women on GHK-Cu (70 percent) than on retinoic acid (40 percent) or vitamin C (50 percent). One study, one metric, not a general ranking (Abdulghani et al., in Pickart and Margolina, 2018).

Injectable data

There is no large, trial-validated systemic human dose. The strongest human skin evidence is topical, so injectable figures circulating online are not established the way the topical data are (Pickart and Margolina, 2018).

heard a couple guys talking about them in a facebook group for lifters, mostly just shipping reliability stuff. checked out their site that night and the way they laid out batch numbers per order was honestly better than any other vendor i had tried over the last year

some guys in a facebook group for guys who travel to vietnam were talking about them pretty positively, mostly about the cold chain staying intact even with long transit. that was my main worry so i looked into it and ordered two vials

i was not expecting it until thursday but it hit the porch on a tuesday morning. 7:15am, i was still in bed. rain was coming down so i was a little worried about the box getting wet. went out, picked it up, dried it off. box was dry, tape was intact. opened it in the bathroom because the light was better there. ghkcu vial was centered, foam was snug. liquid was clear, no discoloration. cap seal was good. no issues.

We Stand Behind Our Quality.

GHK-Cu has decades of published research behind it, studied for skin renewal and wound-repair endpoints. The guarantee is on the material and on how the order is handled, third-party tested with a certificate of analysis on every batch. It is not a guarantee of any outcome.
