What is the difference between Ipamorelin and Semaglutide?
Ipamorelin is a pentapeptide ghrelin receptor agonist reported in 1998 as a selective growth hormone secretagogue in endocrine research (peptide, MW about 711.9 g/mol).
Which is heavier, Ipamorelin or Semaglutide?
Ipamorelin has a molecular weight of about 711.9 g/mol and Semaglutide about 4114 g/mol (PubChem), so Semaglutide is heavier by 3,402.1 g/mol, a ratio of 5.78. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 243.1 nmol for Semaglutide.
How many mg of Semaglutide are equimolar to 1 mg of Ipamorelin?
1 mg of Ipamorelin (MW 711.9) is 1,404.7 nmol. The same number of moles of Semaglutide (MW 4114) weighs 5.779 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of Ipamorelin and Semaglutide
PubChem lists Ipamorelin as C38H49N9O5 (711.9 g/mol) and Semaglutide as C187H291N45O59 (4114 g/mol). Ipamorelin is a peptide; Semaglutide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
