GHK-Cu 100 mg: Pharmaceutical-grade copper peptide for research

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a natural tripeptide that has interested the scientific community for over 50 years. Peptivia Lab offers a pharmaceutical-grade, HPLC-tested 100 mg formulation, assembled and shipped from Canada for laboratory research.

Each lyophilized vial comes with a Certificate of Analysis (COA) certifying a purity of over 99%.

What is GHK-Cu?

GHK-Cu is a complex formed by the GHK tripeptide and a divalent copper ion (Cu²⁺). First identified in 1973 by researcher Loren Pickart, this peptide is naturally present in human plasma, saliva, and urine.

A notable fact highlighted in scientific literature: its plasma concentration declines with age. Studies report levels of approximately 200 ng/mL in a 20-year-old individual, compared to about 80 ng/mL at age 60. This decline coincides with the decrease in the body’s regenerative capacities, which has motivated much of the research on this peptide.

Mechanisms of action studied in research

Scientific publications, notably those by Pickart et al., describe several mechanisms of interest:

• Gene expression modulation — transcriptomic studies have shown that GHK-Cu influences the expression of several thousand human genes, particularly those involved in tissue repair.
• Collagen and elastin synthesis observed in in vitro skin fibroblast models.
• Tissue repair pathways documented in animal wound-healing models.
• Antioxidant properties linked to copper chelation and modulation of cellular oxidative stress.
• Effects studied on hair follicles in hair growth research.

These mechanisms are reported in available scientific literature and are presented for informational purposes only, within a research context.

Frequently Asked Questions (FAQ)

What exactly is GHK-Cu?

GHK-Cu is a tripeptide (glycyl-L-histidyl-L-lysine) bound to a copper ion. It is a molecule naturally present in the human body, studied since the 1970s for its role in tissue regeneration and wound healing.

What is the difference between GHK and GHK-Cu?

GHK is the tripeptide alone, while GHK-Cu is the same tripeptide complexed with a copper ion. This copper-bound form is primarily used in research, as copper plays an essential role in many biological mechanisms being studied.

Is GHK-Cu legal in Canada?

GHK-Cu is sold strictly for laboratory research purposes. It is not approved by Health Canada for human or veterinary use. Our products are intended for scientific research only.

How do I reconstitute my 100 mg GHK-Cu vial?

Add bacteriostatic water to the lyophilized vial using a sterile syringe. The amount of water depends on the desired concentration for your research protocol. Gently tilt the vial until completely dissolved (do not shake vigorously).

How long does reconstituted GHK-Cu last?

Once reconstituted with bacteriostatic water, GHK-Cu must be stored in the refrigerator between 2 and 8°C and used within 60 days.

Do you ship across Canada?

Yes, Peptivia Lab ships across Canada with discreet packaging and full tracking. Delivery times vary by province.

Is a Certificate of Analysis (COA) available?

Yes, an HPLC Certificate of Analysis is available upon request for each batch. Contact our team to obtain the COA corresponding to your order.
