It is extensively studied in preclinical models for its role as a pleiotropic signaling modulator, specifically regarding its influence on gene expression, redox balance, and extracellular matrix (ECM) regulation.\u003c\/p\u003e\u003cp\u003eWhen you buy GHK-Cu from PatriotPeptides.US, you are guaranteed a high-purity research compound verified by independent third-party laboratories to ensure consistent batch quality and data integrity.\u003c\/p\u003e\u003ch2\u003eOverview\u003c\/h2\u003e\u003cp\u003eGHK-Cu is a copper-binding tripeptide — a chain of three amino acids (glycine, histidine, and lysine) bound to a copper(II) ion. Its molecular formula is C₁₄H₂₃CuN₆O₄, with a molecular weight of 404.9 g\/mol and CAS number 89030-95-5. The peptide was first identified in 1973 by Loren Pickart during research on human plasma, where he observed that a small copper-peptide complex was present in younger blood samples at higher concentrations than in older ones.\u003c\/p\u003e\u003cp\u003eThe copper ion is coordinated to the peptide through the nitrogen atoms of the glycine and histidine residues, giving the compound its distinctive blue color in crystalline form. GHK-Cu is naturally found in trace amounts in human plasma, saliva, and urine. It is classified as a metallopeptide — a peptide that incorporates a metal ion as part of its structure. The compound is supplied as a blue crystalline powder, highly soluble in water, and should be stored refrigerated at 36–46°F (2–8°C) and protected from light.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThis product is strictly for research purposes only.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot for human or veterinary use.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePubChem Reference: \u003ca href=\"https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/GHK-Cu\" target=\"_blank\"\u003eView compound profile on NIH PubChem\u003c\/a\u003e\u003c\/p\u003e","brand":"PatriotPeptides.US","offers":[{"title":"Default Title","offer_id":51698459607256,"sku":"GHK-CU-50MG","price":71.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/3045\/3208\/files\/GHK-CU.png?v=1779236045","url":"https:\/\/patriotpeptides.us\/products\/ghk-cu","provider":"PatriotPeptides.US","version":"1.0","type":"link"}
