What is the difference between GHK-Cu and Semaglutide?

Which is heavier, GHK-Cu or Semaglutide?

GHK-Cu has a molecular weight of about 402.92 g/mol and Semaglutide about 4114 g/mol (PubChem), so Semaglutide is heavier by 3,711.1 g/mol, a ratio of 10.21. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 243.1 nmol for Semaglutide.

How many mg of Semaglutide 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 Semaglutide (MW 4114) weighs 10.21 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of GHK-Cu and Semaglutide

PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Semaglutide as C187H291N45O59 (4114 g/mol). GHK-Cu is a peptide-copper complex; Semaglutide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
