The most studied copper peptide is GHK-Cu (glycyl-L-histidyl-L-lysine), a small copper-binding peptide, naturally present in human plasma
One Canadian study showed significant variability of melatonin content in natural health products labelled as melatonin and the presence of other substances [61]
It binds to HGF with high affinity (Kd = 65 pM) and markedly augments the capacity of HGF to activate c-Met phosphorylation, even at subthreshold concentrations of the growth factor
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
Clinical Takeaways for Everyone This isnt just about pregnancy
Consider Cost and Practical Availability In settings where both options are clinically appropriate, practical factors may also influence selection
