GHK-Cu 100mg

GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine. The three-amino-acid sequence binds a copper(II) ion, which gives the powder its characteristic blue colour. It is one of the shortest peptides in the catalogue and the only one supplied as a metal complex.

Chemistry: CAS 49557-75-7 (copper complex), molecular formula C14H24N6O4·Cu, molecular weight approximately 403.9 g/mol for the complex.

Format: lyophilised powder, 50 mg or 100 mg in a sealed glass vial, catalogue reference GHKCUX-01 (50 mg) and GHKCUX-02 (100 mg). The blue colour is normal and expected; a white powder sold as GHK-Cu would indicate the copper-free peptide.

Testing: HPLC purity (specification 99%) and mass-spectrometry identity on every lot, certificate on request.

Buy one, get one free. Add one vial to your basket and a second vial of the same product is added free. The basket, the checkout and the invoice all show two vials. Orders of five or more vials include a free 10 ml vial of bacteriostatic water.

Testing and documentation. Every batch is tested by Janoshik Analytical before release. The certificate reports purity by HPLC (specification 99%) and identity by mass spectrometry, and Janoshik hosts the record on its own verification site. Request the certificate for the lot number printed on your vial and we email it the same working day.

Storage and handling. Keep sealed vials at -20°C, dry and protected from light. Once in solution, keep at 2 to 8°C and avoid repeated freeze-thaw. Dispatched from UK stock the same day when paid before 2pm on a working day.
