What is the difference between GHRP-2 and TB-500?

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 TB-500?

GHRP-2 has a molecular weight of about 818 g/mol and TB-500 about 889 g/mol (PubChem), so TB-500 is heavier by 71 g/mol, a ratio of 1.09. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 1,124.9 nmol for TB-500.

How many mg of TB-500 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 TB-500 (MW 889) weighs 1.087 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of GHRP-2 and TB-500

PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). GHRP-2 is a peptide; TB-500 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 TB-500 in moles?

5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of TB-500 (MW 889) would weigh 5.434 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 TB-500 in moles?

10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of TB-500 (MW 889) would weigh 10.868 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of TB-500 equals how many mg of GHRP-2 in moles?

10 mg of TB-500 (MW 889) is 11.249 µmol. The same amount of GHRP-2 (MW 818) would weigh 9.201 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 2 mg vial of TB-500 equals how many mg of GHRP-2 in moles?

2 mg of TB-500 (MW 889) is 2.25 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.84 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of TB-500 equals how many mg of GHRP-2 in moles?

5 mg of TB-500 (MW 889) is 5.624 µmol. The same amount of GHRP-2 (MW 818) would weigh 4.601 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 15 mg vial of TB-500 equals how many mg of GHRP-2 in moles?

15 mg of TB-500 (MW 889) is 16.873 µmol. The same amount of GHRP-2 (MW 818) would weigh 13.802 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 20 mg vial of TB-500 equals how many mg of GHRP-2 in moles?

20 mg of TB-500 (MW 889) is 22.497 µmol. The same amount of GHRP-2 (MW 818) would weigh 18.403 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
