What is the difference between GHRP-6 and IGF-1 LR3?
GHRP-6 is one of the earliest synthetic growth hormone secretagogue hexapeptides, used as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 873 g/mol).
Which is heavier, GHRP-6 or IGF-1 LR3?
GHRP-6 has a molecular weight of about 873 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,238 g/mol, a ratio of 10.44. This means 1 mg of GHRP-6 contains 1,145.5 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of GHRP-6?
1 mg of GHRP-6 (MW 873) is 1,145.5 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 10.436 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 5 mg vial of GHRP-6 equals how many mg of IGF-1 LR3 in moles?
5 mg of GHRP-6 (MW 873) is 5.727 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 52.182 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-6 equals how many mg of IGF-1 LR3 in moles?
10 mg of GHRP-6 (MW 873) is 11.455 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 104.4 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-6 in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of GHRP-6 (MW 873) would weigh 0.009582 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-6 in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of GHRP-6 (MW 873) would weigh 0.09582 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
