What is the difference between Selank and Tesamorelin?

Which is heavier, Selank or Tesamorelin?

Selank has a molecular weight of about 751.9 g/mol and Tesamorelin about 5136 g/mol (PubChem), so Tesamorelin is heavier by 4,384.1 g/mol, a ratio of 6.83. This means 1 mg of Selank contains 1,330 nmol versus 194.7 nmol for Tesamorelin.

How many mg of Tesamorelin are equimolar to 1 mg of Selank?

1 mg of Selank (MW 751.9) is 1,330 nmol. The same number of moles of Tesamorelin (MW 5136) weighs 6.831 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Selank and Tesamorelin

PubChem lists Selank as C33H57N11O9 (751.9 g/mol) and Tesamorelin as C221H366N72O67S (5136 g/mol). Selank is a peptide; Tesamorelin is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 5 mg vial of Selank equals how many mg of Tesamorelin in moles?

5 mg of Selank (MW 751.9) is 6.65 µmol. The same amount of Tesamorelin (MW 5136) would weigh 34.153 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of Selank equals how many mg of Tesamorelin in moles?

10 mg of Selank (MW 751.9) is 13.3 µmol. The same amount of Tesamorelin (MW 5136) would weigh 68.307 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 Selank in moles?

2 mg of Tesamorelin (MW 5136) is 0.3894 µmol. The same amount of Selank (MW 751.9) would weigh 0.2928 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 Selank in moles?

10 mg of Tesamorelin (MW 5136) is 1.947 µmol. The same amount of Selank (MW 751.9) would weigh 1.464 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 Selank in moles?

5 mg of Tesamorelin (MW 5136) is 0.9735 µmol. The same amount of Selank (MW 751.9) would weigh 0.732 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 Selank in moles?

20 mg of Tesamorelin (MW 5136) is 3.894 µmol. The same amount of Selank (MW 751.9) would weigh 2.928 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
