What drives the GLP-3 price
Price per mg for this compound is set mainly by its size and by one structural addition. It is a synthetic lipidated peptide with the molecular formula C221H342N46O68 and a molecular weight of 4731.4 g/mol, so every vial represents a long solid-phase assembly in which each coupling has to run to completion before the next residue goes on. Long chains lose a little yield at every cycle, and the crude product needs more preparative HPLC before it reaches release purity. Lipidation adds a further conjugation step: a fatty-acid side chain attached through a linker, which raises the mass and lengthens HPLC retention, so the product fractions elute later and take longer to collect cleanly. Those fixed costs are spread over the milligrams in the vial, which is why the 30 mg and 40 mg vials sit well below the 5 mg and 10 mg vials on a per-mg basis in the table above. Read the vial size first and the headline price second.
