Overview
Description
A regenerative copper peptide researched for supporting skin rejuvenation, collagen-related signaling, and hair health. Often chosen for premium aesthetic and anti-aging protocols focused on visible refinement.
GHK-Cu is widely used in research for skin quality, tissue repair signaling, and overall regenerative biology pathways— making it a staple for aesthetic-focused programs.
Scientific Overview
GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. It has been studied for roles in wound-healing processes, extracellular matrix remodeling, antioxidant activity, and growth-factor–related signaling involved in skin and connective tissue maintenance. Research interest includes collagen-related pathways and hair follicle signaling in experimental models.

This product is intended strictly for laboratory research purposes only. It is not approved for human or veterinary use by the FDA or any other regulatory agency. Store in a cool, dry environment prior to reconstitution and handle using appropriate laboratory and aseptic techniques.
Frequently asked questions
Yes. Every batch of GHK-Cu 50mg undergoes independent third-party testing using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). The Certificate of Analysis is published and accessible from the product page.
GHK-Cu 50mg sold by MHS Longevity is verified to 99%+ purity, with the result documented in each batch's Certificate of Analysis. Anything below that threshold is rejected before release.
The Certificate of Analysis for GHK-Cu 50mg is available directly from the product page and on our Third-Party Test Results page. Each COA includes the batch identifier, test date, testing method, and verified purity percentage.
GHK-Cu 50mg ships from our US-based facility with standard or expedited options. Orders over $150 qualify for free standard US shipping. All orders are packaged discreetly with documented handling protocols.
No. GHK-Cu 50mg is supplied strictly for laboratory research purposes only. It is not approved by the FDA for human or veterinary use, and it is not intended to diagnose, treat, cure, or prevent any disease.
MHS Longevity is a veteran-owned operation focused on pharmaceutical-grade research compounds. We source from vetted manufacturers, batch-test independently with HPLC and Mass Spectrometry, and publish every Certificate of Analysis. Pricing is transparent and the testing process is documented end-to-end.
GHK is the uncomplexed tripeptide Gly-His-Lys. GHK-Cu is the copper-coordinated form, where a copper(II) ion is bound by the histidine and adjacent residues. Most published research on this compound is conducted on the copper-loaded form, which is also what gives the powder its characteristic blue color.
HPLC measures the peptide purity, but it doesn't directly verify whether the copper coordination is intact. A high-quality COA for GHK-Cu reports peptide purity (HPLC), confirms peptide identity (MS), and verifies that the material is supplied in the copper-loaded form.
GHK-Cu is sent to an independent third-party laboratory before each batch is released. The lab's identifier, the testing methods used (HPLC, MS, and copper-form verification), and the test date are published on the Certificate of Analysis for that batch.
We stock GHK-Cu in two vial sizes — 50mg and 100mg — drawn from the same supply chain and tested on the same HPLC/MS schedule. Each batch is verified independently and carries its own Certificate of Analysis.

Research details — GHK-Cu 50mg
GHK-Cu is a tripeptide–copper complex first identified in human plasma in the 1970s as a copper-binding compound. The tripeptide sequence Gly-His-Lys binds a copper(II) ion with high affinity, and most published research is conducted on the copper-loaded form, which is what "GHK-Cu" denotes. This guide explains what GHK-Cu is, the research context, and how each batch is verified before release.
What is GHK-Cu?
GHK-Cu refers to the complex of the tripeptide glycyl-histidyl-lysine (GHK) with a single copper(II) ion. The peptide portion has the sequence Gly-His-Lys and a molecular weight of about 340.4 g/mol; the copper-coordinated form (GHK-Cu) has an effective complex weight near 403.9 g/mol depending on the counter-ion. It is supplied as a lyophilized blue-tinted powder — the color comes from the copper coordination — for laboratory reconstitution.
GHK-Cu is sold strictly for laboratory and research use. It is not approved by the FDA or any other regulatory body for human or veterinary use, and nothing in this guide constitutes guidance for human administration.
Research context
Published research on GHK-Cu spans skin and connective-tissue models, with work examining gene-expression changes related to extracellular matrix, fibroblast behavior, and copper-dependent enzyme cofactor pools. The peptide and its copper complex are referenced in over four decades of published literature, with active investigation in both topical-formulation and injectable-research contexts.
How GHK-Cu quality is verified
GHK-Cu testing is slightly more demanding than for a typical lyophilized peptide because the copper coordination must be characterized alongside peptide purity. Every batch of MHS Longevity GHK-Cu is submitted to an independent third-party laboratory before release:
- HPLC separates the GHK peptide species and measures GHK content as a percentage of total peak area. Anything below 99% GHK is rejected.
- Mass Spectrometry confirms the peptide molecule's mass matches Gly-His-Lys, and that no contaminating peptide species are present at appreciable levels.
- Copper-coordination characterization verifies that the supplied material is in the copper-loaded form expected for research use — distinguishing GHK-Cu from uncomplexed GHK peptide.
What a GHK-Cu Certificate of Analysis shows
- Compound name and structural designation. GHK-Cu, with the peptide sequence (Gly-His-Lys) and molecular formula of the complex.
- Batch identifier. The unique ID linking certificate to vial.
- Test date. When the analysis was performed.
- Method. HPLC, MS, and copper-form verification.
- Verified peptide purity %. The HPLC result. We require 99%+.
- Lab and signatures. The independent lab performing the analysis.
Storage and handling (research lab context)
Lyophilized GHK-Cu should be stored at -20°C or below, protected from light. The characteristic blue color of the copper complex is a useful visual check during reconstitution; loss or fading of color can indicate dissociation of the copper coordination. Once reconstituted, the solution is typically held at 2–8°C and used within the documented stability window. Repeated freeze–thaw cycles should be avoided. Standard aseptic technique applies.

Where to buy GHK-Cu 50mg
The same eight questions apply whether you're buying GHK-Cu 50mgfrom us or anywhere else. Vendors who can't answer any of them are worth a closer look.
Vendor evaluation checklist
1. Is the Certificate of Analysis public and downloadable?
A vendor unwilling to publish HPLC/MS results for the batch you're buying has nothing to verify their purity claim against.
2. Which testing method was used — HPLC, Mass Spectrometry, or both?
HPLC measures purity. Mass Spectrometry confirms the molecule's identity. Reputable batches go through both.
3. What's the verified purity percentage on the published COA?
Industry research standard is 99%+. Below that, you're paying for a compound diluted with synthesis byproducts.
4. Where does the product ship from?
US-based fulfillment generally means shorter handling times, customs-free delivery, and clearer return remedies.
5. Is the price published at a single list rate, or hidden behind tier locks?
Opaque pricing is a yellow flag. Transparent vendors quote the same number to every customer.
6. What's the free-shipping threshold, if any?
Compare the all-in cost (product + shipping + handling) — not just the headline price.
7. How is the product stored prior to shipment?
Lyophilized peptides degrade with temperature swings. Vendors should disclose temperature-controlled storage.
8. Is there a documented damage-claim and return policy?
Discreet shipping carries handling risk. A clear, written policy protects you when something goes wrong.
