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?

Primary mechanism: Copper-binding tripeptide; modulates gene expression toward a younger phenotype. Research on GHK-Cu implicates downstream effects on related signalling cascades, with magnitude and clinical relevance dependent on dose, timing, and individual pharmacogenomic factors.

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 dosage & protocol

Reference protocol for GHK-Cu (research context only, drawn from published literature):

  • Per dose: 1–2 mg / day
  • Weekly total: 7–14 mg
  • Frequency: Daily SC or topical
  • Cycle: Ongoing

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.

GHK-Cu — common questions

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.
