GHK-Cu 50mg

Important dilution note: Cloudiness after dilution is most commonly associated with non-pharmaceutical-grade dilution solution. Cloudy product concerns are not eligible for refund unless Pfizer pharmaceutical-grade dilution solution was used.

Vial Size: 3ml

Form: Blue-Green Lyophilized Powder

CAS Number: 49557-75-7

Chemical Name: Glycyl-L-histidyl-L-lysine copper(II) complex

Synonyms: GHK-Cu; Copper peptide GHK; Cu-GHK; Copper(II) GHK

Molecular Formula: C₁₄H₂₂CuN₆O₄

Molecular Weight: 403.9 g/mol

Sequence: Gly-His-Lys tripeptide coordinated with Cu²⁺ via histidine imidazole nitrogen, glycine α-amino group, and deprotonated Gly-His amide nitrogen; square-planar coordination geometry

Purity: ≥98% (HPLC) — see batch COA

Form: Lyophilized blue-green to off-white powder (characteristic of Cu²⁺ complex)

Storage Conditions: Store at −20°C, desiccated, protected from light. Stable 24 months lyophilized.

Solubility: Soluble in sterile water at ≥1 mg/mL

Receptor Activity: Studied for modulation of MMP-1/MMP-2 and TIMP-1/TIMP-2 in ECM remodeling models; copper delivery vehicle for lysyl oxidase and superoxide dismutase (SOD); studied for TGF-β and VEGF signaling in cell culture

Certificate of Analysis: Available for all batches.
