What is the difference between GHRP-2 and Tirzepatide?
GHRP-2 is a synthetic growth hormone secretagogue hexapeptide studied as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 818 g/mol).
Which is heavier, GHRP-2 or Tirzepatide?
GHRP-2 has a molecular weight of about 818 g/mol and Tirzepatide about 4813 g/mol (PubChem), so Tirzepatide is heavier by 3,995 g/mol, a ratio of 5.88. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 207.8 nmol for Tirzepatide.
How many mg of Tirzepatide are equimolar to 1 mg of GHRP-2?
1 mg of GHRP-2 (MW 818) is 1,222.5 nmol. The same number of moles of Tirzepatide (MW 4813) weighs 5.884 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and Tirzepatide
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and Tirzepatide as C225H348N48O68 (4813 g/mol). GHRP-2 is a peptide; Tirzepatide is a peptide (lipidated). These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-2 equals how many mg of Tirzepatide in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of Tirzepatide (MW 4813) would weigh 29.419 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
