What is the difference between Hexarelin and TB-500?

Hexarelin is a synthetic hexapeptide growth hormone secretagogue, also studied for binding to the CD36 receptor in cardiovascular research models (peptide, MW about 887 g/mol).

Which is heavier, Hexarelin or TB-500?

Hexarelin has a molecular weight of about 887 g/mol and TB-500 about 889 g/mol (PubChem), so TB-500 is heavier by 2 g/mol, a ratio of 1. This means 1 mg of Hexarelin contains 1,127.4 nmol versus 1,124.9 nmol for TB-500.

How many mg of TB-500 are equimolar to 1 mg of Hexarelin?

1 mg of Hexarelin (MW 887) is 1,127.4 nmol. The same number of moles of TB-500 (MW 889) weighs 1.002 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Hexarelin and TB-500

PubChem lists Hexarelin as C47H58N12O6 (887 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). Hexarelin is a peptide; TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
