Description
What Is GHK-Cu? (In Plain English)
GHK-Cu is three amino acids linked in a row, wrapped around a single atom of copper like a claw holding a marble. Cells use copper for certain jobs, and this little claw is one way copper gets carried and handed off. Scientists grow skin cells in dishes and add GHK-Cu to see which genes those cells switch on.
GHK-Cu 100mg — Research Overview
GHK-Cu 100mg supplies the copper(II) complex of glycyl-L-histidyl-L-lysine, a tripeptide originally isolated from human plasma fractions. Published work associates the complex with extracellular matrix turnover — collagen and glycosaminoglycan synthesis, and modulation of matrix metalloproteinase and TIMP expression in fibroblast culture — along with widespread transcriptional effects reported in microarray analyses. Mechanistic accounts in the literature centre on copper coordination and intracellular copper delivery rather than on a discrete receptor.
Primary Research Areas
- Extracellular matrix turnover — studied in vitro for MMP/TIMP balance and collagen deposition in dermal fibroblasts
- Follicular and dermal papilla models — investigated in cell culture for proliferation markers in hair-follicle-derived cells
- Angiogenesis assays — examined for endothelial migration and vascular marker expression in animal and culture models
- Metal-peptide coordination chemistry — used as a reference copper-binding ligand in spectroscopic and stability studies
- Transcriptomics — referenced in the literature for large-scale gene-expression signatures in treated cell lines

Related Research Peptides
Groups running copper-peptide comparisons usually hold AHK-Cu 100 mg Research Peptide next to GHK-Cu, since the two differ by a single residue. GHK-Cu also appears as a component in multi-peptide research blends such as Glow Stack 70mg and Klow Stack 80mg, and it is frequently benched alongside Snap-8 | 10mg.
Why Researchers Source GHK-Cu 100mg from Dissolv Labs
Dissolv Labs is a research-supply company based in Southern California. Orders are picked, packed, and shipped domestically from our SoCal facility, so most U.S. laboratories see short transit times and no international customs delay.
Every vial ships as a complete kit. Each GHK-Cu vial is paired with its own bacteriostatic water reconstitution vial, so the material arrives ready to prepare in the lab without a separate diluent order. Compounds are supplied lyophilized in sealed, labeled vials with lot identification, and analytical documentation is available on request.
GHK-Cu 100mg — Frequently Asked Questions
What is GHK-Cu used for?
GHK-Cu is supplied strictly as a research chemical for in vitro and laboratory research applications. The literature investigates the copper tripeptide primarily in dermal fibroblast culture, matrix-remodelling assays, and copper-coordination chemistry. It is not for human or veterinary use.
GHK-Cu vs AHK-Cu — how do they compare?
Both are copper-binding tripeptides, and they differ at the first residue: glycine in GHK, alanine in AHK. GHK-Cu has the larger published record, particularly in matrix and transcriptomic studies, while AHK-Cu appears more often in follicular and endothelial culture work. Investigators comparing copper delivery between the two typically match copper equivalents rather than peptide mass.
Why choose the 100mg GHK-Cu vial?
The 100mg presentation suits laboratories running repeated plate-based assays, where a larger single lot reduces lot-to-lot variability across a study. Because the material is lyophilized and sealed, it stores well cold and shaded until reconstitution. Each vial ships with a matched bacteriostatic water vial, and additional BAC Water 10ml is available for larger working volumes.
Where can I buy GHK-Cu 100mg for sale?
GHK-Cu 100mg ships directly from Dissolv Labs in Southern California, packed and dispatched domestically from our SoCal facility. Orders arrive as a complete kit with the reconstitution vial included, and analytical documentation is available on request to qualified laboratory buyers.
Research Use Only
GHK-Cu is sold exclusively as a Research Use Only (RUO) chemical. It is not a drug, supplement, cosmetic, or food, and it is not intended for human or veterinary use, ingestion, injection, topical application, or any form of consumption. It is intended solely for licensed laboratory research by qualified professionals. Dissolv Labs makes no medical, therapeutic, or diagnostic claims of any kind. By purchasing, the buyer confirms they are a qualified researcher and accepts full responsibility for lawful handling, use, and disposal.
Bacteriostatic (BAC) water is included free with every order.

Exact quantity and concentration are listed in the product title and variant options above. The figures above are release specifications — the measured result for your particular lot is stated on its Certificate of Analysis.
Documentation & Testing
Every batch is tested before release. Testing covers four checks: identity by mass spectrometry, purity by HPLC against a ≥99% release threshold, content verification against the labelled mass, and batch release tied to a specific lot number.
To request the Certificate of Analysis for your vial, email us with your order number or the lot number printed on the label. We do not gate documentation behind a form or a purchase.

Handling & Storage
Lyophilized peptides are relatively stable during transit. Arriving at room temperature is not cause for concern — the cold pack is a margin of safety rather than a pass/fail condition.
Sealed vials of lyophilized material are typically stored refrigerated or frozen and protected from light. Handling protocols for a specific compound are determined by the researcher and their institution; we supply the material and its documentation.
Shipping & Returns
Orders placed before the daily cut-off are dispatched the same business day from Southern California in insulated packaging with ice packs. Tracking is issued at dispatch.
If a shipment arrives damaged, if vial contents appear inconsistent with the specification, or if the lot number on your vial does not match the certificate we provide, contact us and we will resolve it.
Because these are temperature-sensitive laboratory materials, opened vials cannot be returned to stock.
