GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine bound to copper). It is found in human plasma and is widely used as a research compound and cosmetic ingredient associated with skin, hair and recovery support.

It is most often explored by adults focused on skin quality, hair and general recovery support. As with any compound, it is for adults 18 and older and is best discussed with a qualified healthcare professional before use.

GHK-Cu: the copper peptide

A plain-English primer on the copper peptide people ask about most for skin quality, hair and recovery — what it is, who it's for, and how GEN IQ verifies it.

Updated June 2026 · 5 min read · Structure-function education

GHK-Cu is one of the most-asked-about compounds in the skin and recovery world — and one of the most misunderstood. This primer keeps it simple: what the molecule actually is, the goals people associate with it, and the verification that separates a research-grade compound from an unknown powder.

What GHK-Cu is

GHK-Cu is a naturally occurring copper-binding tripeptide — three amino acids (glycine, L-histidine and L-lysine) bound to a copper ion. It's written as GHK-Cu, sometimes called the "copper peptide." It occurs in human plasma and other tissues, and its levels naturally decline with age, which is part of why it draws so much interest in the aesthetics and longevity space.

In research and cosmetic contexts, GHK-Cu is associated with the body's natural repair and skin-remodeling processes. GEN IQ offers it as a research compound for adults — not a drug and not a medical product.

Who explores it

GHK-Cu tends to be of interest to adults focused on:

Skin quality. People who want to support healthy-looking, resilient skin as part of an aesthetics-forward routine.
Hair. Those exploring compounds associated with supporting healthy hair and scalp.
Recovery. Anyone building a routine that supports the body's normal recovery and repair processes.
Longevity-minded routines. Healthspan-focused adults who want research-grade inputs they can verify.

It is intended for adults 18 and older, and you should always speak with a qualified healthcare professional before starting any new compound.

How GEN IQ verifies it

With peptides, the single most important question isn't marketing — it's what's actually in the vial. The GEN IQ Standard answers that three ways:

Made in the USACompounded and filled in US facilities under a controlled process — not drop-shipped from an unknown source.

99%+ purityIdentity and purity that exceeds 99% — verified, not assumed.

Third-party COAAn independent Certificate of Analysis on every batch — verification you can actually read.

The honest framing

GHK-Cu is offered as a research compound. It may help support the goals above as part of a broader routine, but nothing here is a promise of a result, and individual outcomes vary. This page is education for adults 18 and older — not medical advice.
