Peptide mass: 10mg Bacteriostatic water: 2mL Concentration: 10mg 2mL = 5 mg/mL = 5,000 mcg/mL Peptide per unit (100-unit syringe): 5 mg 100 = 0.05 mg/unit = 50 mcg/unit If research protocol calls for 250 mcg per research unit: 250 mcg 50 mcg/unit = 5 units on the syringe Total doses per vial at 250 mcg each: 10,000 mcg 250 mcg = 40 research doses That single 10mg vial, reconstituted with 2mL of bacteriostatic water, provides 40 research doses of 250 mcg each, drawn to the 5-unit mark on a standard insulin syringe
Metal binding and interdomain thermodynamics of mammalian metallothionein-3: enthalpically favoured cu+ Supplants entropically favoured zn 2+ to form cu 4+ Clusters under physiological conditions
If a reducing-agent-containing assay buffer is required, add GHK-Cu in the final step at the working dilution
But since peptide coupling agents are described as immune sensitizers, it stands to reason that the risk even if its small exists for everyone.18 Copper peptide uglies Anecdotal reports suggest that some people may experience worsened skin aging, instead of anti-aging, after using products with GHK-Cu, a rare concern dubbed copper peptide uglies. While this isnt necessarily a safety issue, it is a (again, rare) potential negative effect of using copper peptide products
