GHK-Cu — Wolverine Health

How it works

A copper-binding tripeptide first isolated from human plasma in the 1970s. At physiological concentrations it modulates wound healing, collagen synthesis, and antioxidant enzyme activity. Found naturally in plasma, saliva, and urine — levels decline with age. In vitro and animal evidence for skin remodelling and wound repair is solid; the dermatology literature on topical application is more developed than the systemic injection data. Nobody's done the RCT on subcutaneous injection in humans.

FDA status: No FDA approval. Present in FDA-registered cosmetic products (topical). Systemic injection use is not approved.
WADA status: Permitted in sport
Route: topical; subcutaneous injection (systemic use)

Key studies

Isolation of a serum factor stimulating cell growth from plasma — Pickart et al. (1973)

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) was first isolated from human plasma and identified as a growth-modulating tripeptide that stimulates tissue remodelling and wound contraction.

Research on GHK-Cu

What GHK-Cu actually does — the plain answer

GHK-Cu is a copper-carrying peptide your body makes to repair itself, and makes less of as you age. Here's the plain-English answer: what it could do for you, why the biology is exciting, how far the human proof goes — and where the injectable form sits in the FDA's next compounding review.

Peptide access by US state: why the regulatory patchwork right now is real

The federal compounding framework applies the same way in every state. The state pharmacy boards do not. The result is a real state-by-state patchwork that decides whether a telehealth prescription for a compounded peptide is actually fillable where you live.

What RFK Jr.'s February 2026 announcement actually said about peptides

The "announcement" was a Joe Rogan appearance, not a Federal Register notice. The wellness scene heard one thing. The actual signal was narrower, and the rulemaking that turns it into access is still more than a year away.

The PCAC review is July 23–24, 2026. Here is what that means for peptide access.

Two days at FDA's White Oak campus decide which of seven peptides US compounding pharmacies will be allowed to dispense by prescription. The vote is not an approval, the docket is not all the peptides, and the framing the forums use is mostly wrong.

Anti-inflammatory peptides: what calming chronic inflammation could do for you

WADA

Chronic, low-grade inflammation tracks with slower recovery, stiff joints, and how fast you age. Three peptides under FDA review — KPV, BPC-157, and GHK-Cu — each turn it down from a different direction. Here is what that could mean for you, and how far the human proof actually goes.

Collagen-synthesis peptides: what a better repair signal could do for you

WADA

Collagen is the scaffolding under your skin, tendons, and joints — and three peptides now in front of the FDA each lean on how your body builds it. Here is what that could mean for repair and ageing, why the biology is genuinely exciting, and how far the human proof actually goes.

Copper peptides: why GHK-Cu is not just a skincare trend

Copper is a metal your body repairs itself with — but too reactive to carry loose, so it travels clipped to a small peptide. That's a copper peptide, like GHK-Cu. Here's why the biology is exciting, how far the human proof goes, and where the injectable sits in the FDA's next compounding review.

GHK-Cu: what fifty years of research says it could do for you

GHK-Cu is a copper-carrying repair peptide your body makes and loses with age. It turns up in skincare, longevity, and injury protocols — here's what it could do across all three, how far the human proof goes, and where the injectable form sits in the FDA's next compounding review.

GHK-Cu: the repair molecule your body stops making

GHK-Cu is a copper-carrying peptide your body makes to repair skin and tissue — and you make less of it every year. The early science on putting it back is genuinely exciting. Here is what it could do for you, and how far the proof actually goes.

BPC-157 vs GHK-Cu: which repair peptide fits which kind of healing

WADA

BPC-157 and GHK-Cu both get sold as tissue-repair peptides, but they are tools for two different jobs — BPC-157 for deep tissue like tendon and gut, GHK-Cu for skin and surface. Here is what each could do for you, which goal each one fits, and how far the proof actually goes.
