What is the difference between Tesamorelin and IGF-1 LR3?
Tesamorelin is a stabilised analogue of the full 44-residue GHRH with an N-terminal trans-3-hexenoyl group, used in GHRH receptor research (peptide, MW about 5136 g/mol).
Which is heavier, Tesamorelin or IGF-1 LR3?
Tesamorelin has a molecular weight of about 5136 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 3,975 g/mol, a ratio of 1.77. This means 1 mg of Tesamorelin contains 194.7 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Tesamorelin?
1 mg of Tesamorelin (MW 5136) is 194.7 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 1.774 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 0.1 mg vial of IGF-1 LR3 equals how many mg of Tesamorelin in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Tesamorelin (MW 5136) would weigh 0.05637 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 1 mg vial of IGF-1 LR3 equals how many mg of Tesamorelin in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Tesamorelin (MW 5136) would weigh 0.5637 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 IGF-1 LR3 in moles?
2 mg of Tesamorelin (MW 5136) is 0.3894 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 3.548 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 IGF-1 LR3 in moles?
10 mg of Tesamorelin (MW 5136) is 1.947 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 17.739 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 IGF-1 LR3 in moles?
5 mg of Tesamorelin (MW 5136) is 0.9735 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 8.87 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 IGF-1 LR3 in moles?
20 mg of Tesamorelin (MW 5136) is 3.894 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 35.479 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
