What is the difference between GHK-Cu and Sermorelin?
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 Sermorelin?
GHK-Cu has a molecular weight of about 402.92 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Sermorelin is heavier by 2,955 g/mol, a ratio of 8.33. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin 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 Sermorelin (MW 3357.9) weighs 8.334 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHK-Cu and Sermorelin
PubChem lists GHK-Cu as C14H23CuN6O4+ (402.92 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). GHK-Cu is a peptide-copper complex; Sermorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
