What is the difference between GHK-Cu and Tirzepatide?

Which is heavier, GHK-Cu or Tirzepatide?

GHK-Cu has a molecular weight of about 402.92 g/mol and Tirzepatide about 4813 g/mol (PubChem), so Tirzepatide is heavier by 4,410.1 g/mol, a ratio of 11.95. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 207.8 nmol for Tirzepatide.

How many mg of Tirzepatide 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 Tirzepatide (MW 4813) weighs 11.945 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of GHK-Cu and Tirzepatide

PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Tirzepatide as C225H348N48O68 (4813 g/mol). GHK-Cu is a peptide-copper complex; Tirzepatide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
