GHK-Cu
Also known as: GHK Cu, GHK peptide, GHK copper peptides, ghk buy
GHK is the amino acid sequence glycine-histidine-lysine, a naturally occurring tripeptide found in human plasma, and Cu is the chemical symbol for copper. The tripeptide binds a copper ion with high affinity, and that complex is what the name refers to.
CU is the periodic table symbol for copper making it a copper peptide available for purchase online.
GHK-Cu is supplied in Australia by Peptide House with fast domestic shipping to all states and territories.
Most of the research of GHK-Cu sits in skin and wound healing: collagen and elastin synthesis, antioxidant activity, and modulation of gene expression in fibroblasts. It’s the one compound in this space with a genuinely different regulatory position in Australia, since topical copper peptides are used in cosmetic skincare rather than being captured as prescription-only, unlike the injectable research peptides.

- Skin remodelling
Collagen and elastin synthesis, fibroblast activity, wrinkle depth. Some human topical trial data. - Wound healing
Granulation tissue, angiogenesis, extracellular matrix remodelling. - Gene expression
Microarray work showing broad shifts in expression profile. The most active current area. - Hair growth
Follicle size and stimulation. - Antioxidant activity

Frequently Asked Questions
What is GHK-Cu Peptide?
GHK-Cu (copper peptide) is a naturally occurring tripeptide, glycyl-L-histidyl-L-lysine, bound to a copper ion. Found in human plasma, it declines with age, and is researched for collagen and elastin synthesis, skin remodelling, wound healing, hair follicle stimulation, antioxidant activity and gene expression modulation.
Has there been research done on GHK-Cu?
Yes, spanning roughly five decades since its discovery in the early 1970s. Maquart's groupshowed GHK-Cu regulates glycosaminoglycan and small proteoglycan expression in wounded skin (J Invest Dermatol, 2000). A 2015 rat ACL reconstruction study found improved healing, though the authors described it as transient. A 2016 mouse study reported reduced lipopolysaccharide-induced acute lung injury.
Can BPC-157 be bought online in Australia?
Yes. GHK-Cu can be bought online in Australia from peptide suppliers such as Peptide House. However, GHK-Cu is not TGA-approved for human therapeutic use and is considered an unapproved peptide product.
Is GHK-Cu known as anything else?
Yes, quite a few names for the same thing. Most people search for it as "copper peptide" or "blue copper," and on skincare labels it appears as Copper Tripeptide-1. Scientifically it's glycyl-L-histidyl-L-lysine copper, sometimes written GHK-Cu(II), Cu-GHK or just copper tripeptide, with GHK referring to the peptide on its own without the copper bound.
Can I get GHK-Cu at a pharmacy?
Not as a normal off-the-shelf pharmacy medicine. GHK-Cu is not TGA-approved in Australia, so you generally can’t walk into Chemist Warehouse or a regular pharmacy and buy it. In limited circumstances, a doctor may prescribe an unapproved or compounded medicine for an individual patient, and a compounding pharmacy may then supply it if the legal requirements are met.
How do you reconstitute BPC-157?
In general, “reconstitution” means adding a specified sterile diluent to a lyophilised powder to reach a known concentration, but the correct amount of diluent can be found via our Peptide Calculator. We also highly recommend that all research is done using BAC water.
How does GHK-Cu work?
GHK-Cu binds copper and carries it into cells, where it supports collagen crosslinking and antioxidant enzymes. In fibroblasts it stimulates collagen and elastin synthesis while modulating matrix metalloproteinases, driving tissue remodelling rather than simple buildup.
Where to buy GHK-Cu in Australia?
If you want to purchase GHK-Cu in Australia for research, one suitable option is purchasing from an online retailer such as Peptide House.
Why is GHK-Cu referred to as a research chemical?
GHK-Cu is a research chemical as it is not FDA approved and subsequently TGA approved. All Peptides sold on this website are intended for research use and not sold for human consumption
