In brief: 0% Progesterone
Levonorgestrel is a progestin and not an actual hormone.
It useful because it will act similarly to the natural hormone progesterone. The Plan B one step pill contains 1.5 mg of levonorgestrel. Except for the filler, matrix, and binder required to create the pill itself is 100% of the medication.
