Quick Answer — What is GHK-Cu?
GHK-Cu is a naturally-occurring tripeptide (glycyl-L-histidyl-L-lysine) complexed with copper (Cu2+). In published research it drives collagen synthesis, activates fibroblasts, promotes wound healing, and modulates approximately 4,000 human genes toward a youthful expression profile.

What Is GHK-Cu?
GHK-Cu is a naturally-occurring tripeptide-copper complex, discovered by Loren Pickart in 1973 when investigating the anti-aging factor in human plasma. The three-amino-acid sequence glycyl-L-histidyl-L-lysine (GHK) has high affinity for copper ions (Cu2+), and the resulting GHK-Cu complex is the biologically active form found in plasma, saliva, and urine — declining from an average of 200 ng/mL at age 20 to under 80 ng/mL by age 60.
The peptide has a molecular weight of approximately 340 Da (free GHK) or 402 Da as the copper complex, with empirical formula C14H23CuN6O4. It is supplied as a high-purity lyophilized powder with the characteristic pale blue colour of the copper complex. GHK-Cu is laboratóriumi kutatási célra szolgál and is not intended for human or veterinary diagnosis or therapy. For mechanism, genomic analysis, and published research summaries, see our full GHK-Cu research guide.
Mechanism of Action — Copper Carrier and Gene Regulator
GHK-Cu’s mechanism is unusually broad because the tripeptide functions both as a copper carrier (transporting Cu2+ into cells) and a gene-expression regulator acting on thousands of targets. Three mechanistic pathways dominate the published literature:
- Copper transport — GHK binds Cu2+ with high affinity and delivers it across cell membranes. Copper is a cofactor for lysyl oxidase (the enzyme that crosslinks collagen and elastin), superoxide dismutase, and cytochrome C oxidase. The copper-delivery mechanism is the unique feature distinguishing GHK-Cu from non-copper peptides.
- Fibroblast activation and collagen synthesis — GHK-Cu upregulates collagen types I and III, decorin, and glycosaminoglycans in dermal fibroblast research. This is the mechanistic basis of the skin, wound-healing, and connective-tissue research signal.
- Gene expression modulation — Pickart’s 2010 genomic analysis identified GHK as a modulator of approximately 4,000 human genes, with a net effect of shifting expression patterns toward a more youthful profile. Affected gene clusters include DNA-repair, antioxidant-defense, and stress-response pathways.
Because these three mechanisms operate across many tissue types, GHK-Cu has been investigated in research contexts ranging from dermatology and wound healing to gene-expression biology and neuronal survival research. It is remarkably well tolerated at typical research doses.

How It Compares — GHK-Cu vs Other Healing Peptides
GHK-Cu, BPC-157, és TB-500 are the three most-cited healing-research peptides. Each acts via distinct mechanisms, which is why they are frequently combined rather than substituted:
| Kritérium | GHK-Cu | BPC-157 | TB-500 |
|---|---|---|---|
| Length | 3 amino acids + copper | 15 amino acids | 43 amino acids |
| Primary mechanism | Copper transport + gene regulation | VEGF + NO + GH receptor | G-actin binding, angiogenesis |
| Legjelentősebb kutatási eredmény | Skin, hair, collagen, gene expression | Tendon, ligament, gut barrier | Cardiac, systemic muscle, vascular |
| Tipikus kutatási adag | 1–3 mg daily or 3–5x weekly | 250–500 mcg 1–2x daily | 2–2.5 mg twice weekly |

Tárolás és rekonstitúció
Rekonstitúció előtt: store lyophilized vials refrigerated at 2–8 °C in original packaging. Stable for up to 36 months. The lyophilized GHK-Cu has a characteristic pale blue colour from the copper complex.
Rekonstitúciós eljárás: inject bacteriostatic water down the side wall of the peptide vial. Solution should be clear light blue — the colour of the Cu2+ complex. Swirl gently — do nem shake — and allow 2–5 minutes for full dissolution.
Rekonstitúció után: store refrigerated at 2–8 °C and use within 30 days. Light-blue colour should persist; loss of colour may indicate copper-peptide dissociation. Discard if cloudy or discoloured (brown/green).
Gyakran Ismételt Kérdések
What is GHK-Cu used for in research?
GHK-Cu is used in laboratory research investigating skin regeneration, hair follicle biology, wound healing, collagen synthesis, gene-expression modulation, and antioxidant pathways. It is nem FDA-approved and is sold here strictly for laboratory research use only.
Why does GHK-Cu look blue?
The blue colour is the hallmark of the copper(II)-GHK complex. The Cu2+ ion coordinates with the histidine imidazole ring and deprotonated amide nitrogens of the tripeptide, producing the characteristic pale-blue absorption spectrum. A properly reconstituted GHK-Cu solution should be clear and light blue.
What is the typical GHK-Cu research dose?
Published preclinical protocols typically use 1–3 mg per administration, given once daily or 3–5 times per week for 4–8 week cycles. A 50 mg vial reconstituted with 5.0 mL bacteriostatic water yields 10 mg/mL — 10 ticks on a U-100 syringe delivers 1 mg.
Is GHK-Cu FDA approved?
No. GHK-Cu is not approved by the FDA, EMA, or any other regulator for therapeutic use. It is widely used in cosmetic skincare products as an ingredient, but the injectable research form sold here is for laboratory investigation only.
How should GHK-Cu be stored?
Lyophilized vials: refrigerated at 2–8 °C in original packaging, stable up to 36 months. Reconstituted solution: refrigerated at 2–8 °C, use within 30 days. The blue colour should persist throughout storage — loss of colour may indicate peptide-copper dissociation.
How do I reconstitute GHK-Cu?
Follow the reconstitution chart above. Add bacteriostatic water down the side wall of the vial, swirl gently, and allow 2–5 minutes for full dissolution. The solution should be clear light blue. Do nem shake the vial.
Can GHK-Cu be stacked with BPC-157 or TB-500?
Yes. GHK-Cu is frequently co-administered with BPC-157 and/or TB-500 in connective-tissue, wound-healing, and skin-regeneration research because their mechanisms are complementary. GHK-Cu provides copper and gene-expression signaling; BPC-157 provides growth-factor upregulation; TB-500 provides systemic angiogenesis.
Is injectable GHK-Cu different from topical cosmetic GHK-Cu?
The peptide itself is the same molecule. Cosmetic formulations target skin absorption at low concentrations (typically 0.1–1%); injectable research forms deliver much higher doses systemically via SC injection for laboratory investigation. Our product is the injectable research form, not a cosmetic.
Milyen erősségű készítményeket tart készleten a MedsBase?
MedsBase carries GHK-Cu in 50 mg lyophilized vials, available in 10-vial, 20-vial, or 30-vial pack sizes. All vials are supplied at 99%+ HPLC purity with a certificate of analysis available on request.
Does GHK-Cu cause side effects in research?
Published preclinical research has reported a clean safety profile at typical research doses. Copper delivery is tightly regulated by the body’s endogenous transport proteins, which likely contributes to the low off-target signal. Long-term human safety data are not available.
What is the half-life of GHK-Cu?
GHK-Cu is a small tripeptide-copper complex with an estimated free-peptide plasma half-life of under 30 minutes. However, GHK demonstrates strong affinity for collagen, fibronectin, and other extracellular matrix proteins, which effectively extends its local tissue residence time considerably beyond plasma half-life measurements.
How does GHK-Cu work differently from growth-hormone secretagogue peptides?
Unlike GHRPs or GHRH analogs, GHK-Cu operates primarily through gene-expression modulation. Microarray studies have shown that GHK activates or suppresses over 4,000 human genes, including those governing collagen synthesis, antioxidant defence, nerve regeneration, and anti-inflammatory pathways. This broad genomic action distinguishes it from receptor-specific peptides such as BPC-157 or Ipamorelin.
Can I order GHK-Cu for international shipping?
Yes. MedsBase ships GHK-Cu worldwide from our dedicated peptide shipping network. Peptide-only orders qualify for our standalone peptide shipping service. Orders ship in temperature-controlled packaging with full tracking.
GHK-Cu is most often run alongside dedicated tissue-repair peptides for the deeper-tissue work; pair with our Peptide Gyógyító Stack (BPC-157 5 mg + TB-500 5 mg + bakteriostatikus víz) for the angiogenesis + cytoskeletal layer that complements GHK-Cu’s collagen and antioxidant effects.
