What is the difference between GHRP-6 and Sermorelin?
GHRP-6 is one of the earliest synthetic growth hormone secretagogue hexapeptides, used as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 873 g/mol).
Which is heavier, GHRP-6 or Sermorelin?
GHRP-6 has a molecular weight of about 873 g/mol and Sermorelin about 3357.9 g/mol (PubChem), so Sermorelin is heavier by 2,484.9 g/mol, a ratio of 3.85. This means 1 mg of GHRP-6 contains 1,145.5 nmol versus 297.8 nmol for Sermorelin.
How many mg of Sermorelin are equimolar to 1 mg of GHRP-6?
1 mg of GHRP-6 (MW 873) is 1,145.5 nmol. The same number of moles of Sermorelin (MW 3357.9) weighs 3.846 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-6 and Sermorelin
PubChem lists GHRP-6 as C46H56N12O6 (873 g/mol) and Sermorelin as C149H246N44O42S (3357.9 g/mol). GHRP-6 is a peptide; Sermorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-6 equals how many mg of Sermorelin in moles?
5 mg of GHRP-6 (MW 873) is 5.727 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 19.232 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-6 equals how many mg of Sermorelin in moles?
10 mg of GHRP-6 (MW 873) is 11.455 µmol. The same amount of Sermorelin (MW 3357.9) would weigh 38.464 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-6 in moles?
2 mg of Sermorelin (MW 3357.9) is 0.5956 µmol. The same amount of GHRP-6 (MW 873) would weigh 0.52 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-6 in moles?
5 mg of Sermorelin (MW 3357.9) is 1.489 µmol. The same amount of GHRP-6 (MW 873) would weigh 1.3 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-6 in moles?
10 mg of Sermorelin (MW 3357.9) is 2.978 µmol. The same amount of GHRP-6 (MW 873) would weigh 2.6 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
