What is the difference between GHRP-2 and Tesamorelin?

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 Tesamorelin?

GHRP-2 has a molecular weight of about 818 g/mol and Tesamorelin about 5136 g/mol (PubChem), so Tesamorelin is heavier by 4,318 g/mol, a ratio of 6.28. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 194.7 nmol for Tesamorelin.

How many mg of Tesamorelin 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 Tesamorelin (MW 5136) weighs 6.279 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of GHRP-2 and Tesamorelin

PubChem lists GHRP-2 as C45H55N9O6 (818 g/mol) and Tesamorelin as C221H366N72O67S (5136 g/mol). GHRP-2 is a peptide; Tesamorelin 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 Tesamorelin in moles?

5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of Tesamorelin (MW 5136) would weigh 31.394 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 Tesamorelin in moles?

10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of Tesamorelin (MW 5136) would weigh 62.787 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

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

2 mg of Tesamorelin (MW 5136) is 0.3894 µmol. The same amount of GHRP-2 (MW 818) would weigh 0.3185 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

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

10 mg of Tesamorelin (MW 5136) is 1.947 µmol. The same amount of GHRP-2 (MW 818) would weigh 1.593 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

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

5 mg of Tesamorelin (MW 5136) is 0.9735 µmol. The same amount of GHRP-2 (MW 818) would weigh 0.7963 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

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

20 mg of Tesamorelin (MW 5136) is 3.894 µmol. The same amount of GHRP-2 (MW 818) would weigh 3.185 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
