What is the difference between GHK-Cu and Vesugen?
GHK-Cu is a copper(II) complex of the tripeptide GHK, first identified in human plasma, and widely studied in skin-biology, cosmetic-science and wound-model research (peptide-copper complex, MW about 402.92 g/mol).
Which is heavier, GHK-Cu or Vesugen?
GHK-Cu has a molecular weight of about 402.92 g/mol and Vesugen about 390.39 g/mol (PubChem), so GHK-Cu is heavier by 12.53 g/mol, a ratio of 1.03. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 2,561.5 nmol for Vesugen.
How many mg of Vesugen are equimolar to 1 mg of GHK-Cu?
1 mg of GHK-Cu (MW 402.92) is 2,481.9 nmol. The same number of moles of Vesugen (MW 390.39) weighs 0.9689 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Vesugen
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Vesugen as C15H26N4O8 (390.39 g/mol). GHK-Cu is a peptide-copper complex; Vesugen is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHK-Cu equals how many mg of Vesugen in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of Vesugen (MW 390.39) would weigh 4.845 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 50 mg vial of GHK-Cu equals how many mg of Vesugen in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of Vesugen (MW 390.39) would weigh 48.445 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHK-Cu equals how many mg of Vesugen in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of Vesugen (MW 390.39) would weigh 9.689 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of GHK-Cu equals how many mg of Vesugen in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of Vesugen (MW 390.39) would weigh 19.378 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of GHK-Cu equals how many mg of Vesugen in moles?
