What is the difference between GHK-Cu and Gonadorelin?
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 Gonadorelin?
GHK-Cu has a molecular weight of about 402.92 g/mol and Gonadorelin about 1182.3 g/mol (PubChem), so Gonadorelin is heavier by 779.4 g/mol, a ratio of 2.93. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 845.8 nmol for Gonadorelin.
How many mg of Gonadorelin 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 Gonadorelin (MW 1182.3) weighs 2.934 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Gonadorelin
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Gonadorelin as C55H75N17O13 (1182.3 g/mol). GHK-Cu is a peptide-copper complex; Gonadorelin 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 Gonadorelin in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of Gonadorelin (MW 1182.3) would weigh 14.672 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 Gonadorelin in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of Gonadorelin (MW 1182.3) would weigh 146.7 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 Gonadorelin in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of Gonadorelin (MW 1182.3) would weigh 29.343 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 Gonadorelin in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of Gonadorelin (MW 1182.3) would weigh 58.687 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 Gonadorelin in moles?
