Description
GHK-Cu is a naturally occurring copper-binding tripeptide and one of the most researched compounds in skin and tissue biology. Limitless Life Nootropics supplies it in 100mg and 200mg vials, made in the USA and independently tested.
What Is GHK-Cu?
The tripeptide glycyl-L-histidyl-L-lysine was first isolated from human plasma by Dr. Loren Pickart in 1973. It has a very high affinity for copper(II) ions, and the resulting complex is thought to act as a carrier that delivers copper to tissues where it is needed for enzymes involved in collagen and elastin formation.
Plasma levels of the peptide decline significantly with age, which has made it a popular subject in aging research. Laboratory studies have examined its effects on fibroblast activity, collagen and glycosaminoglycan synthesis, antioxidant enzymes and the expression of a large number of genes linked to tissue repair.
The copper complex gives the powder its characteristic blue color. We offer Premium lyophilized and Non-Lyophilized grades in 100mg and 200mg sizes.
Key Research Areas
The scientific literature describes this peptide across several areas of investigation:
- Collagen, elastin and glycosaminoglycan synthesis
- Fibroblast proliferation and dermal remodeling
- Wound contraction and angiogenesis models
- Antioxidant enzyme and gene expression studies
- Hair follicle and scalp research
Researchers can review peer-reviewed studies on the GHK-copper complex through the National Library of Medicine (PubMed) database.

Frequently Asked Questions
Why is the powder blue?
The blue color comes from the copper(II) ion bound to the tripeptide, which is normal for this compound.
What is the difference from GHK Basic?
GHK Basic is the same tripeptide without copper, allowing researchers to study the peptide independently of copper delivery.
Is this peptide for human use?
No. It is sold strictly for laboratory research. It is not intended for human or animal consumption, diagnosis or treatment.
Where can I buy GHK-Cu online?
You can order it directly from Limitless Life Nootropics, a U.S. supplier of third-party tested research peptides with fast, discreet shipping.
