GHK-Cu 50 mg — Research Consultation
GHK-Cu is the copper-bound form of the tripeptide glycyl-L-histidyl-L-lysine. The published literature describes effects on extracellular-matrix gene expression, copper-dependent enzyme cofactor activity, and skin-research applications. This page summarises the literature and links you into an in-chat research consultation with Nour.
What GHK-Cu is
GHK (glycyl-L-histidyl-L-lysine) is a tripeptide that occurs naturally in human plasma at concentrations that decline with age. GHK has high copper-binding affinity; the GHK-Cu complex is the biologically-relevant form studied in the published literature. Researchers studying GHK-Cu work with copper as part of the molecule, not as a separate ligand.
What the published literature covers
Pickart, Margolina and collaborators have published extensively on GHK-Cu since the 1970s. The literature spans gene-expression modulation (RNA-sequencing studies showing up- and down-regulation of thousands of human genes), copper-dependent enzyme cofactor activity, skin extracellular-matrix research (collagen, elastin, glycosaminoglycans), and wound-research models. Cosmetic and dermatological applications have separate published evidence bases — researchers reading the literature should be careful to distinguish cosmetic-grade topical use from research-grade injectable preparations.
Quality verification
Wellness Labs supplies lyophilised GHK-Cu 50 mg manufactured under ICH Q7 GMP standards. Independent HPLC analysis at a US-based third-party laboratory verifies peak-area purity at ≥98% against pharmacopoeia reference standards. Copper content is verified separately by ICP-MS. Each released batch carries a Certificate of Analysis available through the in-chat consultation.
Talk to Nour before you commit
Nour walks through the protocol options published in the GHK-Cu research literature — including the distinction between cosmetic topical research and injectable research preparations — and helps you decide if GHK-Cu fits your research question. English or Arabic.
Common research questions
- Is GHK-Cu legal in the UAE?
- GHK-Cu is classified as a research compound in the UAE and is sold through standard wellness-supply channels. Wellness Labs operates under standard UAE commercial trading rules with VAT compliance applied to every dispatch.
- What dose ranges does the published research use?
- Published topical-research protocols describe formulations of 0.05-2% GHK-Cu. Injectable research protocols in the grey-research community describe 1-2 mg subcutaneous, several times per week, in cycles of 4-8 weeks. No consensus optimal protocol exists for injectable use — the published evidence is largely topical and the injectable literature is preliminary.
- Difference between cosmetic GHK-Cu and research-grade GHK-Cu?
- Cosmetic-grade GHK-Cu is formulated for topical skin research at low concentrations in a serum or cream base. Research-grade lyophilised GHK-Cu (what Wellness Labs supplies) is the pure peptide-copper complex in powder form, intended for reconstitution at the researcher's chosen concentration. The two are not interchangeable.
- Why copper? Could it be toxic?
- The copper is bound stoichiometrically (1:1) to the GHK tripeptide in the released form, which is the biologically-relevant form in the published literature. Researchers concerned about copper exposure should review the published toxicology — the doses used in published research are well below thresholds associated with acute copper toxicity, but cumulative exposure over long cycles is a researcher-judgment call.
- How is purity verified?
- Every released batch carries a Certificate of Analysis showing HPLC peak-area purity (≥98%) plus ICP-MS verification of copper content. Method specifications are published on our quality page. Customers can request the COA through the chat.
- Shelf life and storage?
- Lyophilised GHK-Cu is ambient-temperature stable in transit. Long-term storage at -20°C protected from light. After reconstitution, refrigerated storage per the supplied protocol.
- How fast is delivery in the UAE?
- Same-day delivery within Dubai, next-business-day across the rest of the UAE.
- Can I ask Nour about the difference between GHK-Cu and other copper peptides?
- Yes. Tap "Start a research consultation". Nour will walk through GHK-Cu specifically and how it differs from other copper-peptide research preparations in the literature.
