What is the difference between Ipamorelin and Semax?

Ipamorelin is a pentapeptide ghrelin receptor agonist reported in 1998 as a selective growth hormone secretagogue in endocrine research (peptide, MW about 711.9 g/mol).

Which is heavier, Ipamorelin or Semax?

Ipamorelin has a molecular weight of about 711.9 g/mol and Semax about 813.9 g/mol (PubChem), so Semax is heavier by 102 g/mol, a ratio of 1.14. This means 1 mg of Ipamorelin contains 1,404.7 nmol versus 1,228.7 nmol for Semax.

How many mg of Semax are equimolar to 1 mg of Ipamorelin?

1 mg of Ipamorelin (MW 711.9) is 1,404.7 nmol. The same number of moles of Semax (MW 813.9) weighs 1.143 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.

Compare the molecular formulas of Ipamorelin and Semax

PubChem lists Ipamorelin as C38H49N9O5 (711.9 g/mol) and Semax as C37H51N9O10S (813.9 g/mol). Ipamorelin is a peptide; Semax is a peptide. These formulas refer to the parent compounds without salt counter-ions.

A 2 mg vial of Ipamorelin equals how many mg of Semax in moles?

2 mg of Ipamorelin (MW 711.9) is 2.809 µmol. The same amount of Semax (MW 813.9) would weigh 2.287 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of Ipamorelin equals how many mg of Semax in moles?

10 mg of Ipamorelin (MW 711.9) is 14.047 µmol. The same amount of Semax (MW 813.9) would weigh 11.433 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of Ipamorelin equals how many mg of Semax in moles?

5 mg of Ipamorelin (MW 711.9) is 7.023 µmol. The same amount of Semax (MW 813.9) would weigh 5.716 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 5 mg vial of Semax equals how many mg of Ipamorelin in moles?

5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 4.373 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 10 mg vial of Semax equals how many mg of Ipamorelin in moles?

10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 8.747 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.

A 30 mg vial of Semax equals how many mg of Ipamorelin in moles?

30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of Ipamorelin (MW 711.9) would weigh 26.24 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
