What is the difference between Sermorelin and Tirzepatide?
Sermorelin is the 29-residue N-terminal fragment of growth hormone-releasing hormone, the shortest fully active GHRH fragment, used in GHRH receptor research (peptide, MW about 3357.9 g/mol).
Which is heavier, Sermorelin or Tirzepatide?
Sermorelin has a molecular weight of about 3357.9 g/mol and Tirzepatide about 4813 g/mol (PubChem), so Tirzepatide is heavier by 1,455.1 g/mol, a ratio of 1.43. This means 1 mg of Sermorelin contains 297.8 nmol versus 207.8 nmol for Tirzepatide.
How many mg of Tirzepatide are equimolar to 1 mg of Sermorelin?
1 mg of Sermorelin (MW 3357.9) is 297.8 nmol. The same number of moles of Tirzepatide (MW 4813) weighs 1.433 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Sermorelin and Tirzepatide
PubChem lists Sermorelin as C149H246N44O42S (3357.9 g/mol) and Tirzepatide as C225H348N48O68 (4813 g/mol). Sermorelin is a peptide; Tirzepatide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
