GHK-Cu 100mg

Description

What is GHK-Cu?

GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). First isolated from human plasma in 1973 by Loren Pickart, GHK is a small signalling peptide with high affinity for copper ions. Plasma GHK concentrations are approximately 200 ng/mL in young adults and decline to around 80 ng/mL by age 60 — an observation that has motivated much of the research on exogenous GHK-Cu supplementation in laboratory models.

Its deep cobalt-blue colour, characteristic of copper coordination, confirms the metal-peptide complex. It is supplied by Revial Labs as a lyophilised (freeze-dried) powder for reconstitution in bacteriostatic water. All product is intended strictly for laboratory research use.

Areas of Research Investigation

GHK-Cu has been studied for over four decades across several biological domains. Published areas of research investigation include:

• Skin and dermal repair models — studies of fibroblast activity, collagen synthesis, and glycosaminoglycan production in skin research.
• Wound-healing research — investigation into re-epithelialisation and matrix remodelling in dermal and corneal repair models.
• Copper delivery and enzyme cofactor studies — research into GHK-Cu as a delivery mechanism for copper to lysyl oxidase and other copper-dependent enzymes.
• Gene expression studies — research from Pickart and colleagues documenting modulation of over 4,000 genes associated with extracellular matrix and antioxidant pathways.
• Hair follicle research — laboratory studies of follicle biology and copper-dependent signalling.

This is a summary of published research directions and should not be interpreted as claims about the compound’s effects in humans. GHK-Cu is not approved by the MHRA, FDA, or any equivalent regulatory body for human or veterinary therapeutic use.

Reconstitution

GHK-Cu is typically reconstituted in bacteriostatic water for research purposes. The reconstituted solution takes on the characteristic deep-blue colour of the copper complex.

For step-by-step guidance, see our article How to Reconstitute Research Peptides, or use our Peptide Reconstitution Calculator.

Storage and Handling

• Before reconstitution: Store at 2–8°C (refrigerator) for long-term storage. Short-term room-temperature storage is acceptable during shipping.
• After reconstitution: Store the solution at 2–8°C and use within four weeks. Protect from direct light.
• Avoid: Direct sunlight, freeze-thaw cycles, and repeated agitation.

Frequently Asked Questions

What is included with this product?

One sealed vial containing 100mg of lyophilised GHK-Cu powder. Bacteriostatic water, syringes, and alcohol swabs are sold separately — see our Starter Accessory Pack for a bundled option.

How pure is Revial Labs GHK-Cu?

All GHK-Cu supplied by Revial Labs is manufactured to ≥99% purity and independently verified by High-Performance Liquid Chromatography (HPLC). A batch-specific Certificate of Analysis is available on request.

Why is GHK-Cu blue?

The deep cobalt-blue colour is characteristic of the copper(II) coordination complex, where the copper ion is coordinated by the histidine imidazole nitrogen, the N-terminal amine, and adjacent binding sites. The colour is a visual confirmation that the copper-peptide complex is intact.

How is GHK-Cu shipped?

Orders are dispatched via Royal Mail tracked delivery from the UK, typically within one working day. Peptides remain stable at ambient temperature during transit; refrigeration is recommended once received.

Is a Certificate of Analysis included?

A batch-specific COA verifying identity, purity, and mass spectrometry is available on request. Contact us with your order number and we will send the corresponding document.
