Full shipping informationGHK-Cu is a naturally occurring copper-binding tripeptide (Glycyl-L-histidyl-L-lysine copper complex) studied extensively in tissue biology and cellular remodeling research. Concentration declines with age, making it a key compound in age-related biological studies. Class-level specification ≥98%; selected lots independently tested.
Key research areas:
- Tissue remodeling and extracellular matrix pathways
- Collagen and decorin synthesis stimulation
- Gene expression modulation (over 4,000 genes identified)
For research purposes only. Not for human consumption.
Description
About GHK-Cu
GHK-Cu (CAS 49557-75-7) is a tripeptide-copper complex first isolated from human plasma by Dr. Loren Pickart in 1973. Endogenous plasma concentrations decline from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60, a reduction that correlates with diminished tissue remodeling capacity. This naturally occurring peptide has become one of the most studied compounds in regenerative biology and gene expression research.
Mechanism of Action
GHK-Cu functions as a biological signaling molecule that binds copper(II) ions with high affinity, facilitating copper delivery to enzymatic processes essential for tissue maintenance. The peptide activates TGF-beta and VEGF signaling pathways, stimulating fibroblast proliferation, collagen I/III synthesis, and glycosaminoglycan production. Gene expression studies using the Connectivity Map database have identified GHK as a modulator of over 4,000 human genes.

Why researchers choose CertaPeptides
Who actually tests this?
Selected lots are independently verified by Janoshik Analytical (Czech Republic) and published on the Janoshik public portal. Other lots ship with the supplier's batch specification. See /coa for the published wall.
View COAs →What if I get the wrong batch?
Every vial label carries a code. Look it up on our Verify page: it shows what CertaPeptides publishes for that code and, for a withdrawn lot, that the lot was withdrawn and why. If yours is withdrawn, or if the code on your label finds nothing, email us that code.
View COAs →Where does it ship from?
Romania (EU). We are CERTALAB SRL, CUI 54169956, VAT-registered. Sameday for Romania, GLS for most EU destinations, TCE Worldwide for the remaining cross-border EU and non-EU markets (UK, Switzerland). Delivery 1–15 business days depending on destination — exact window shown at checkout.
Shipping details →What if there's a problem?
You have a 14-day withdrawal right under OUG 34/2014 (Romanian/EU consumer law), with escalation to ANPC and alternative dispute resolution (SAL) available. Contact us at support@chinapeptideshop.com.
Returns policy →Product Information
This product is intended for scientific research and development purposes only. It is a chemical substance that shall not be used as a drug, medicine, active substance, or ingredient in any product intended for human or animal consumption. Researchers must handle this compound in accordance with their institutional biosafety guidelines. Use only in properly equipped laboratory settings with appropriate personal protective equipment.
Peptides in lyophilized (freeze-dried) form are shipped in sealed glass vials using standard delivery methods and do not require refrigeration during transit. Lyophilized peptides are highly stable at ambient temperatures for the duration of standard shipping (typical transit windows are shown at checkout). Once received, transfer the product to refrigerated storage (2–8°C) promptly.
Frequently Asked
Research peptides are supplied in lyophilized (freeze-dried) form. The amount of material is typically only a few milligrams — appearing as a very thin film or small pellet at the bottom of the vial, often nearly invisible. This is completely normal.
Unlike some suppliers who add bulk fillers (such as Mannitol), CertaPeptides provides pure peptide without unnecessary additives.
