Molecular formula: Not publicly disclosed Molecular weight: Estimated 4,0005,000 Da CAS / PubChem ID: Not assigned due to investigational status Form: Lyophilized acetate salt This structure enables multi-receptor engagement, supporting studies on incretin and glucagon signaling interactions

GHK-Cu (copper peptides) GHK-Cu special considerations: Contains copper = oxidation concern More sensitive than most peptides Color changes indicate degradation Shelf life: Lyophilized frozen: 1-2 years (shorter than most) Lyophilized refrigerated: 6-12 months Reconstituted: 21-28 days (some say 21 days safer) Color monitoring: Fresh GHK-Cu: Light blue or clear with blue tint Acceptable: Maintained blue color Degrading: Deepening blue or turning brown/green Bad: Brown, green, or black = severely degraded Storage best practices: Freeze powder (very important for GHK-Cu) Protect from light religiously (amber vials ideal) Reconstitute smaller amounts (2-3 weeks vs 4 weeks) Monitor color weekly Discard if color darkens significantly See our GHK-Cu 50mg copper peptide dosage , copper peptides GHK-Cu guide , and should copper peptides be refrigerated
This note supports D50.0, documents medical necessity, satisfies MEAT for HCC capture, and justifies any downstream infusion or pharmacy claim
