GHK-Cu Capsules · 3MG

GHK-Cu Oral Capsules deliver 3mg of the Glycyl-L-Histidyl-L-Lysine copper(II) complex per capsule in a gelatin capsule format with microcrystalline cellulose as the standard capsule excipient. GHK-Cu is the original copper-binding tripeptide pioneered by Loren Pickart in the early 1970s and one of the most extensively-studied peptide ingredients across cosmetic, dermatological, and biomedical research literature. This oral capsule format is offered for laboratory research applications investigating oral copper peptide chemistry, gastric stability of copper-coordinated peptide complexes, and comparative pharmacology versus topical and lyophilized injectable copper peptide research formats. GHK-Cu has been investigated extensively across decades of academic literature for extracellular matrix protein synthesis research, dermal fibroblast cell biology, hair follicle dermal papilla research, and copper coordination chemistry — with research groups led by Pickart, Maquart, Pollard, and others contributing substantially to the published literature.
