What is the difference between GHRP-2 and Sermorelin?
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 Sermorelin?
GHRP-2 has a molecular weight of about 818 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Sermorelin is heavier by 2,539.9 g/mol, a ratio of 4.11. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin 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 Sermorelin (MW 3357.9) weighs 4.105 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and Sermorelin
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). GHRP-2 is a peptide; Sermorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-2 equals how many mg of Sermorelin in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 20.525 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-2 equals how many mg of Sermorelin in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 41.05 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Sermorelin equals how many mg of GHRP-2 in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of GHRP-2 (MW 818) would weigh 0.4872 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Sermorelin equals how many mg of GHRP-2 in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.218 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Sermorelin equals how many mg of GHRP-2 in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of GHRP-2 (MW 818) would weigh 2.436 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
