GHK-Cu (Copper Peptide)
GHK-Cu is a naturally occurring copper complex of the tri-peptide glycyl-L-histidyl-L-lysine. Since its discovery, GHK-Cu has been a focal point in regenerative medicine due to its unique ability to modulate the expression of a vast number of human genes, particularly those involved in collagen synthesis, angiogenesis, and anti-inflammatory responses. In laboratory settings, GHK-Cu is researched for its capacity to promote the activation of fibroblasts and the production of glycosaminoglycans, making it an essential tool for studying dermal remodeling, wound healing acceleration, and cellular senescence reversal.
Our GHK-Cu is synthesized in an ISO 9001:2015 certified environment using high-precision synthesis and controlled chelation with copper ions to ensure a stable, high-affinity complex. We achieve a chemical purity of ≥99%, verified by HPLC and MS. The resulting product is characterized by its distinct deep blue color and superior stability, providing the reliability required for high-resolution studies into extracellular matrix (ECM) stability and stem cell proliferation.

Key Features & Quality Assurance
Pharmaceutical-Grade Lyophilization
Our proprietary vacuum-sealing process ensures the GHK-Cu powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and maintains the chemical stability of the copper-peptide bond during storage.
Optimal Chelation Stability
Our synthesis process guarantees that the copper ions are perfectly chelated within the GHK sequence, preventing premature dissociation and ensuring consistent bioactivity in experimental assays.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the GHK-Cu cake is at the base.
-
Solvent: Reconstitute with Sterile Water or Bacteriostatic Water.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution becomes a clear, transparent blue.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
-
Post-Reconstitution: Store at 2–8°C and utilize within 14 days for optimal results.
