What is the difference between GHK-Cu and Hexarelin?
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 Hexarelin?
GHK-Cu has a molecular weight of about 402.92 g/mol and Hexarelin about 887 g/mol (PubChem), so Hexarelin is heavier by 484.1 g/mol, a ratio of 2.2. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 1,127.4 nmol for Hexarelin.
How many mg of Hexarelin 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 Hexarelin (MW 887) weighs 2.201 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Hexarelin
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Hexarelin as C47H58N12O6 (887 g/mol). GHK-Cu is a peptide-copper complex; Hexarelin 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 Hexarelin in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of Hexarelin (MW 887) would weigh 11.007 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 Hexarelin in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of Hexarelin (MW 887) would weigh 110.1 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 Hexarelin in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of Hexarelin (MW 887) would weigh 22.014 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 Hexarelin in moles?
