What is the difference between GHRP-2 and IGF-1 LR3?
GHRP-2 is a synthetic growth hormone secretagogue hexapeptide studied as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 818 g/mol).
Which is heavier, GHRP-2 or IGF-1 LR3?
GHRP-2 has a molecular weight of about 818 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,293 g/mol, a ratio of 11.14. This means 1 mg of GHRP-2 contains 1,222.5 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of GHRP-2?
1 mg of GHRP-2 (MW 818) is 1,222.5 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 11.138 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 5 mg vial of GHRP-2 equals how many mg of IGF-1 LR3 in moles?
5 mg of GHRP-2 (MW 818) is 6.112 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 55.691 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-2 equals how many mg of IGF-1 LR3 in moles?
10 mg of GHRP-2 (MW 818) is 12.225 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 111.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 0.1 mg vial of IGF-1 LR3 equals how many mg of GHRP-2 in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of GHRP-2 (MW 818) would weigh 0.008978 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 GHRP-2 in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of GHRP-2 (MW 818) would weigh 0.08978 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
