Quick answers

What is GHK-Cu and what is it used for in research?
GHK-Cu is classified within the Longevity & Cellular group. Naturally occurring copper-tripeptide. Declines with age; modulates ~4000 human genes in vitro. Research applications focus on the pathways outlined below. All references on this page describe published research only, GHK-Cu is supplied for in-vitro and laboratory use, not for human consumption.
How does GHK-Cu work?
Primary mechanism: Copper-binding tripeptide; modulates gene expression toward a younger phenotype. Downstream effects depend on dose, timing, and the biological system under investigation. Receptor binding and post-receptor signalling for GHK-Cu remain areas of active study, and several proposed effects are supported only by preclinical data.
What is the typical GHK-Cu research dose?
Published research protocols for GHK-Cu describe per-dose ranges of 1–2 mg / day, with a weekly total near 7–14 mg, administered daily sc or topical. Typical cycle: ongoing. These ranges reflect the literature and are not dosing recommendations for any individual.
Where can I buy GHK-Cu in Thailand?
GHK-Cu is supplied by Thailand Peptides, a Bangkok-based research-peptide supplier. Orders are placed directly via WhatsApp to the Bangkok research desk, no cart, no account, no forms. Pricing and shipping are provided on request. Open a line with the research desk →
How fast can GHK-Cu be delivered in Thailand?
Same-week delivery across Thailand is standard for orders confirmed within business hours (GMT+7, Monday–Saturday). Bangkok metro deliveries typically arrive within 1–3 business days; other provinces within 3–5. Regional Southeast Asia shipping is available on request.

What is GHK-Cu?

GHK-Cu is a research peptide in the Longevity & Cellular class. Copper-binding tripeptide; modulates gene expression toward a younger phenotype. It is studied at per-dose ranges of 1–2 mg / day (7–14 mg weekly), administered daily sc or topical over cycles of ongoing. Supplied in Thailand by Thailand Peptides, Bangkok-based, research use only.

Naturally occurring copper-tripeptide. Declines with age; modulates ~4000 human genes in vitro.

Published and preclinical data are summarised below; dose ranges shown reflect protocols in the research literature and should be interpreted accordingly.

How does GHK-Cu work?

GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) whose concentration declines with age. In vitro gene-expression profiling has identified modulation of approximately 4,000 human genes, including upregulation of genes involved in tissue remodelling, antioxidant defence, and anti-inflammatory pathways. Collagen synthesis, glycosaminoglycan production, and wound-healing endpoints are the most frequently cited research outcomes.

Receptor binding affinity and post-receptor signalling for GHK-Cu remain areas of active investigation; several proposed effects within the Longevity & Cellular class are currently supported only by in-vitro or rodent data, and should be interpreted accordingly.

GHK-Cu pharmacokinetics

Half-life
Short circulating half-life for the copper-bound tripeptide; topical absorption rates vary by vehicle.
Bioavailability
Both SC and topical application used in research; topical penetration modulated by formulation.
Route of administration
Subcutaneous injection or topical application (cream, serum) in research and cosmetic formulations.
Metabolic clearance
Rapid proteolytic degradation of the Gly-His-Lys sequence; copper retained by serum ligands.

GHK-Cu injection & handling

Reconstitution
Typical research prep: 50–100 mg vial + bacteriostatic water to a working concentration (e.g., 10 mg/mL).
Storage
Lyophilised powder at −20 °C protected from light; reconstituted solution refrigerated, with copper complex generally stable for 2–4 weeks.
Sites used in the research literature
Subcutaneous abdomen for injection; topical application to target skin region.

Handling notes reflect methods used in published research protocols, not medical dosing guidance.

Stacking GHK-Cu

Commonly referenced pairing with GHK-Cu: Topical + SC. Stacking rationale should be grounded in complementary mechanisms, not additive speculation; interactions at shared receptors or enzymatic pathways should be accounted for. Both compounds in a GHK-Cu stack are supplied by Thailand Peptides on the same order via the Bangkok research desk.

Contraindications

Wilson's disease. Additional caution is warranted in individuals with hepatic or renal impairment, endocrine disorders, or concurrent pharmacotherapy affecting the pathways described above.
