About GHK-Cu (Copper Peptide)

GHK-Cu, glycyl-L-histidyl-L-lysine copper(II), is a naturally occurring copper-binding tripeptide first isolated from human plasma. Plasma concentrations of GHK-Cu decline significantly with age, a finding that has driven research interest in its potential roles in tissue maintenance and repair.

Research Applications

GHK-Cu is studied for collagen and glycosaminoglycan synthesis, fibroblast activity, anti-inflammatory effects via cytokine modulation, and emerging research on neurotrophin expression. The 50mg vial size is suitable for standard reconstitution research protocols.

For in vitro research use only. Not for human or veterinary use, therapeutic, or diagnostic purposes.

Research at a Glance
  • What it is: A small copper-binding tripeptide, three amino acids locked to a copper ion.
  • Researchers have studied it for: how copper-peptide biology drives matrix remodeling, growth-factor output, and gene expression in cell and animal models.
  • Evidence level: Almost all preclinical (isolated cells and short animal work). One human wound-repair trial is registered but still recruiting.
  • The short version: Most of what researchers know about GHK-Cu comes from cells in a dish and short animal studies of copper-peptide biology. They frame it as a modulator of tissue remodeling, but the human case is not settled. This is a summary of research, not a reason to use anything.

Frequently asked questions

Does the product come with instructions?

No. Etched supplies research materials, not use instructions. Each vial ships labeled with the compound name, the labeled amount, and the lot number, and that is what comes in the box. Etched does not provide instructions for use, dosing, or administration for any product, on the label, on this page, or by email. General laboratory handling notes (storage, what bacteriostatic water is) are on the FAQ page at https://etchedresearch.com/faq/. All products are sold for research use only, not for human consumption.

What is the amount of peptide in this product?

The label reads GHK-Cu 50mg. That figure is the labeled net quantity of GHK-Cu in the vial, supplied as lyophilized (freeze-dried) powder. It is not the weight of the vial and not a reconstituted volume. Where a Janoshik Analytical report exists for a lot, the measured result for that lot is on the report itself, and the reports that exist are listed on the COA page at https://etchedresearch.com/coa/. Etched ships lyophilized powder only.

Are additional supplies needed?

Nothing else is included, and Etched sells the lyophilized compound only. Bacteriostatic water is sterile water with a small amount of benzyl alcohol added, used in laboratory settings to reconstitute lyophilized (freeze-dried) research peptides into solution. Etched does not sell bacteriostatic water as a product. It is described here only to explain the reconstitution step in a research context. Any supplies a laboratory setting requires are sourced by the researcher.

How is purity verified?

By a third-party laboratory, named. Janoshik Analytical confirms compound identity by mass spectrometry and measures purity by HPLC. Etched does not use vague "third-party tested" language without naming the lab. The measured number for a tested lot is on that lot's report, not a mood word. Where a Janoshik report exists for a compound it is listed on the COA page at https://etchedresearch.com/coa/, and the report itself carries the lot number and the measured purity. Not every listing has a report posted yet, and the COA page shows which do.

Where do products ship from?

Etched ships within the United States only. There is no international shipping. Orders are fulfilled domestically from within the USA. Orders ship in plain, unmarked packaging with no indication of the contents on the outside.

Who is eligible to purchase?

Etched sells to buyers who are 21 years of age or older and who are qualified researchers, research professionals, or affiliated with a research institution, purchasing for in vitro laboratory research. Every order requires an attestation to those three points at checkout, and the order will not process without it. Research Use Only (RUO) means a product is sold only as a material for laboratory and research use. RUO compounds are not drugs, are not approved by the FDA for human consumption, and are not sold or intended for personal use. Shipping is to United States addresses only.
