About this product
GHK-CU Canada — Copper Peptide Complex for Research GHK-Cu is copper-complexed glycyl-L-histidyl-L-lysine — a tripeptide that occurs naturally in human plasma, saliva, and urine, and declines measurably with age. At 29, plasma concentrations run around 200 ng/mL; by 60, that drops to roughly 80 ng/mL. That age-related decline is part of what drew early researchers to it. The copper binding defines GHK-Cu's biology. The tripeptide chelates Cu²⁺ with high affinity, and it's this metal-peptide complex — not the peptide alone — that interacts with cell surface receptors to modulate gene expression. Studies examining this have found effects on over 4,000 genes in cultured cells, including upregulation of collagen, elastin, and several growth factors. That's a broad downstream footprint for a three-amino acid compound. Skin biology research has been the primary published area: collagen I and III synthesis, matrix metalloproteinase balance, glycosaminoglycan production, keratinocyte proliferation. Beyond skin, GHK-Cu appears in wound healing research and some hair follicle studies investigating effects on the anagen phase. Available in Canada from Kirei Clinic. Independent HPLC analys...

Frequently asked
questions
What is GHK-CU used for?
GHK-CU is a copper peptide studied for skin and anti-aging research. Copper-binding tripeptide that promotes collagen synthesis and tissue remodeling. Published research has examined its role in skin regeneration, collagen production, wound healing.
Can I buy GHK-CU in Canada?
Yes. Kirei Clinic ships GHK-CU to all Canadian provinces — Ontario, British Columbia, Alberta, Quebec, Manitoba, Saskatchewan, and all territories. It's available strictly for non-clinical laboratory research purposes.
What purity is Kirei Clinic's GHK-CU?
Every batch is independently tested to 99%+ purity by third-party HPLC. Mass spectrometry confirms peptide identity. A Certificate of Analysis documenting purity, molecular weight, and batch data is included with every order.
How should I store GHK-CU?
Store lyophilized GHK-CU at 2-8°C in the original sealed vial. After reconstitution with bacteriostatic water, refrigerate at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles — aliquot if multiple uses are planned.
How do I reconstitute GHK-CU?
Draw bacteriostatic water into a syringe and inject slowly against the vial wall — not directly onto the powder. Swirl gently to dissolve; never shake. Common volumes are 1 mL, 2 mL, or 2.5 mL depending on the concentration needed. Let sit for a minute if not fully dissolved.
Is GHK-CU legal in Canada?
GHK-CU is legal to purchase in Canada for non-clinical laboratory research. It is not approved by Health Canada for therapeutic use and is not intended for human consumption. Kirei Clinic sells it strictly for research applications.
How does GHK-CU differ from bpc-157?
Both GHK-CU and bpc-157 are used in skin and anti-aging research research but work through different mechanisms. GHK-CU is a copper peptide. Researchers often study them in parallel to compare mechanism-specific effects.
What documentation comes with GHK-CU?
Every order includes a Certificate of Analysis (COA) with: HPLC purity results (99%+), mass spectrometry data, batch number, manufacturing date, and expiry date. This provides full traceability for research records.
