What is the difference between GHK-Cu and IGF-1 LR3?
GHK-Cu is a copper(II) complex of the tripeptide GHK, first identified in human plasma, and widely studied in skin-biology, cosmetic-science and wound-model research (peptide-copper complex, MW about 402.92 g/mol).
Which is heavier, GHK-Cu or IGF-1 LR3?
GHK-Cu has a molecular weight of about 402.92 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,708.1 g/mol, a ratio of 22.61. This means 1 mg of GHK-Cu contains 2,481.9 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of GHK-Cu?
1 mg of GHK-Cu (MW 402.92) is 2,481.9 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 22.612 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 5 mg vial of GHK-Cu equals how many mg of IGF-1 LR3 in moles?
5 mg of GHK-Cu (MW 402.92) is 12.409 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 113.1 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 50 mg vial of GHK-Cu equals how many mg of IGF-1 LR3 in moles?
50 mg of GHK-Cu (MW 402.92) is 124.1 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 1,130.6 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHK-Cu equals how many mg of IGF-1 LR3 in moles?
10 mg of GHK-Cu (MW 402.92) is 24.819 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 226.1 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 20 mg vial of GHK-Cu equals how many mg of IGF-1 LR3 in moles?
20 mg of GHK-Cu (MW 402.92) is 49.638 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 452.2 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of GHK-Cu equals how many mg of IGF-1 LR3 in moles?
30 mg of GHK-Cu (MW 402.92) is 74.456 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 678.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 100 mg vial of GHK-Cu equals how many mg of IGF-1 LR3 in moles?
100 mg of GHK-Cu (MW 402.92) is 248.2 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 2,261.2 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 GHK-Cu in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 0.004422 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 GHK-Cu in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of GHK-Cu (MW 402.92) would weigh 0.04422 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
