Buy GHK-Cu 100mg UK | Research Grade

GHK-Cu is a naturally occurring tripeptide complex consisting of the amino acid sequence glycine-histidine-lysine bound to a copper(II) ion. It is endogenously produced in human plasma and declines significantly with age — plasma concentration roughly halves between the third and seventh decades of life. This decline has driven decades of research interest in exogenous GHK-Cu as a model peptide for skin remodelling, wound healing and connective-tissue regeneration.

Published research shows GHK-Cu modulating expression of more than 4,000 genes, shifting patterns toward those of younger tissue in transcriptomic studies. Documented activities include:

• Dermal fibroblast collagen and elastin synthesis
• Upregulation of decorin and other proteoglycans
• Copper-mediated antioxidant defence
• Suppression of inflammatory cytokines
• Hair follicle outgrowth in dermal papilla cell models
• Accelerated wound contraction in dermal repair studies

Published research has investigated GHK-Cu in skin remodelling and anti-ageing dermatological studies, full-thickness wound-healing models, hair follicle outgrowth and androgenetic alopecia research, copper homeostasis studies, antioxidant pathway research, transcriptomic reprogramming studies, and cosmetic chemistry research. The 100mg vial is suited to extended research protocols requiring larger working volumes.

Store the lyophilised vial at -20°C, sealed and protected from light. GHK-Cu is light-sensitive — always keep the vial wrapped or in an opaque container. Reconstitute with bacteriostatic water (0.9% benzyl alcohol). After reconstitution, store at 2–8°C and use within 5–7 days. For longer-term storage, aliquot and freeze at -20°C and use frozen aliquots within 3 months. Do not refreeze thawed material — copper peptides are notably sensitive to repeated freeze–thaw cycles.

Every GHK-Cu 100mg lot is independently tested by Janoshik Analytical or Aspen Bioanalytics to ≥98% HPLC-UV purity with mass-spectrometry identity confirmation against the published molecular weight of 340.38 Da. Copper content is verified separately. The signed PDF Certificate of Analysis is downloadable from this product page and matches the lot number on the vial.

Copper peptides degrade rapidly under poor storage conditions — a vial that has cycled above 0°C in transit may already be partially oxidised before it reaches your bench. UK Peptides stocks GHK-Cu in temperature-controlled storage, dispatches in insulated mailers with ice packs, and ships same-day via Royal Mail Tracked 24 to maintain cold chain throughout. Combined with third-party batch verification, this is the most reliable source of research-grade GHK-Cu in the UK.
