What is the difference between GHRP-2 and Hexarelin?
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 Hexarelin?
GHRP-2 has a molecular weight of about 818 g/mol and Hexarelin about 887 g/mol (PubChem), so Hexarelin is heavier by 69 g/mol, a ratio of 1.08. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 1,127.4 nmol for Hexarelin.
How many mg of Hexarelin 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 Hexarelin (MW 887) weighs 1.084 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-2 and Hexarelin
PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and Hexarelin as C47H58N12O6 (887 g/mol). GHRP-2 is a peptide; Hexarelin 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 Hexarelin in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of Hexarelin (MW 887) would weigh 5.422 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 Hexarelin in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of Hexarelin (MW 887) would weigh 10.844 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 2 mg vial of Hexarelin equals how many mg of GHRP-2 in moles?
2 mg of Hexarelin (MW 887) is 2.255 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.844 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Hexarelin equals how many mg of GHRP-2 in moles?
5 mg of Hexarelin (MW 887) is 5.637 µmol. The same amount of GHRP-2 (MW 818) would weigh 4.611 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Hexarelin equals how many mg of GHRP-2 in moles?
10 mg of Hexarelin (MW 887) is 11.274 µmol. The same amount of GHRP-2 (MW 818) would weigh 9.222 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
