What is GHK-Cu?

GHK-Cu is the copper(II) complex of GHK, a tripeptide of glycine, histidine and lysine (glycyl-L-histidyl-L-lysine). GHK occurs naturally in human plasma, saliva and urine, and reviews report that its level falls with age. It binds copper ions with high affinity, and the copper complex is the form most often studied. GHK was first described in 1973 as an activity in human albumin. In cell and animal work GHK-Cu has been examined for its effects on fibroblast growth, collagen and glycosaminoglycan synthesis, blood vessel growth and wound closure. More recent mouse studies report that it binds the enzyme SIRT1 in muscle and airway models and peroxiredoxin 6 in a lung model. Controlled human data are limited to skin care products applied to the skin. Tasman supplies GHK-Cu as a lyophilised powder for laboratory research.

Treated irradiated fibroblasts produced significantly more basic FGF and VEGF than untreated controls early after exposure.

What these studies don't show: The only controlled human study here is a 13-patient trial of topical skin care products, and its objective measures found no difference between groups. The injectable-route data are from mice, and several of those abstracts do not state the dose, route or duration. No study here measured long-term safety in people, and the cell and animal results cannot be read as effects in humans.

Is GHK-Cu available in Australia?

GHK-Cu is not registered on the ARTG as a medicine, and no TGA-approved GHK-Cu product exists. The TGA has named GHK-Cu, often supplied in injectable form, among the unapproved peptide products it has raised public health concerns about. Tasman supplies GHK-Cu only as a research material for laboratory work, not for human use. Read more →

Side effects reported in studies

The one controlled human trial of GHK-Cu skin care products did not report adverse events in its abstract, and a microneedle study in pig skin observed no obvious skin irritation. In a mouse silicosis model the authors reported no significant systemic toxicity. Read more →

Doses used in studies

The cited studies used very different amounts: topical skin care products in the one human trial (concentration not stated in the abstract), 0.2 and 2 mg/kg in a mouse muscle model, and 1 × 10⁻⁹ mol/L in cultured fibroblasts. Several animal abstracts do not state a dose at all. This is a report of study methods, not a guide. Read more →

GHK-Cu FAQ

Where can I buy GHK-Cu in Australia?

Tasman supplies research-grade GHK-Cu from Australian stock for laboratory research only. It comes as lyophilised powder in 50 mg and 100 mg vials, and it is tested by HPLC before dispatch. GHK-Cu is not registered on the ARTG as a medicine, and it is not sold for human or veterinary use.

How much is GHK-Cu per mg?

The cost per mg depends on the vial size you choose. The size table on this page lists the 50 mg and 100 mg vials side by side, so the per-mg figure for each can be read straight from it. The larger vial holds twice the powder, which changes the per-mg figure.

What is the difference between the 50 mg and 100 mg GHK-Cu vials?

The only difference is the amount of GHK-Cu powder in the vial: 50 mg or 100 mg. The material, testing and storage are the same. The larger vial needs more diluent to reach a given concentration, and the reconstitution calculator on this site works out the arithmetic for either size.

How should GHK-Cu be stored?

Dry GHK-Cu powder is stored at −20 °C, kept dry and away from light. Once mixed, reconstituted peptides are generally reported to be kept at 2–8 °C and used within 28 days. Avoid repeated warming and cooling of the vial, and keep it sealed between uses.

Is GHK-Cu legal in Australia?

GHK-Cu is not registered on the ARTG, and no TGA-approved GHK-Cu product exists. The TGA has named GHK-Cu among the unapproved peptide products it has raised public health concerns about. Tasman supplies it only as a research material for laboratory work. The Australia legal page sets out what the TGA sources say.

What is GHK-Cu studied for?

GHK-Cu is mostly studied for skin and tissue repair. Cell and animal work has looked at fibroblast growth, collagen synthesis, blood vessel growth and wound closure, and recent mouse studies have looked at lung fibrosis, airway remodelling and smoke-induced muscle loss. The one controlled human trial here tested topical skin care products after laser resurfacing.

What GHK-Cu dosage was used in studies?

The studies used very different amounts depending on the model. The mouse muscle study used 0.2 and 2 mg/kg, a fibroblast study used 1 × 10⁻⁹ mol/L, and the human trial used topical products without a stated concentration. These are the doses used in those studies only. The dosage page lists each one with its source.

Are there GHK-Cu before and after results?

The only controlled before-and-after measurement in people here is a 13-patient trial of skin care products after laser resurfacing. Blinded evaluators found no significant difference from the control group in redness, wrinkles or skin quality at 12 weeks, although patient-rated improvement was higher with GHK-Cu. The results page covers the detail.

GHK-Cu vs BPC-157: what is the difference?

GHK-Cu is a copper-bound tripeptide of three amino acids, while BPC-157 is a 15-amino-acid peptide derived from a gastric protein. GHK-Cu research centres on skin, fibroblasts and collagen, with one small human skin trial. BPC-157 research is mostly rat work on gut, tendon, vessel and nerve injury. The two are combined in the GLOW blend.

Is there a GHK-Cu starter kit?

Yes. The GHK-Cu starter kit pairs a vial with the supplies used to reconstitute it for laboratory work. The kit page lists exactly what is in the box. It is supplied for research use only, like the vial on its own.
