50+ years of research. One breakthrough ingredient.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human blood plasma. Discovered in 1973 by Dr. Loren Pickart, it was first identified when researchers noticed that liver cells from older people behaved like young cells when exposed to young blood plasma.

The active ingredient turned out to be GHK-Cu — a small peptide that acts as a signal molecule, telling your cells to repair damage, produce collagen, and reset gene expression to younger, healthier patterns.

The key insight: your body already makes this peptide. You just make less of it every decade. By age 60, your GHK-Cu levels have dropped significantly — which correlates directly with visible aging.

The skincare market is full of active ingredients that promise results. Here's how GHK-Cu stacks up — based on published research, not marketing claims.

GHK-Cu is a naturally occurring compound. No pharmaceutical company can own exclusive rights to it, which means no one is spending millions of dollars to market it to you. The research exists — over 60 published studies in peer-reviewed journals — but there's no billion-dollar company behind it pushing it into mainstream awareness.

Don't take our word for it. Read the research yourself:

• GHK-Cu may prevent oxidative stress in skin
• GHK peptide as a natural modulator of multiple cellular pathways
• Reversing gene expression: GHK-Cu resets 4,000+ genes

That's why we built Ethos Labs. To take the most clinically validated peptide in skincare and make it accessible — without the $200+ price tag that luxury brands charge for their proprietary (and often less-studied) peptide blends.
