What is the difference between Sermorelin and TB-500?

Sermorelin is the 29-residue N-terminal fragment of growth hormone-releasing hormone, the shortest fully active GHRH fragment, used in GHRH receptor research (peptide, MW about 3357.9 g/mol).

Which is heavier, Sermorelin or TB-500?

Sermorelin has a molecular weight of about 3357.9 g/mol and TB-500 about 889 g/mol (PubChem), so Sermorelin is heavier by 2,468.9 g/mol, a ratio of 3.78. This means 1 mg of Sermorelin contains 297.8 nmol versus 1,124.9 nmol for TB-500.

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

1 mg of Sermorelin (MW 3357.9) is 297.8 nmol. The same number of moles of TB-500 (MW 889) weighs 0.2647 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Sermorelin and TB-500

PubChem lists Sermorelin as C149H246N44O42S (3357.9 g/mol) and TB-500 as C38H68N10O14 (889 g/mol). Sermorelin is a peptide; TB-500 is a peptide. These formulas refer to the parent compounds without salt counter-ions.
