The stats strip lists 4 sprays daily and 0.60 mL per serving.
Four pumps equal about 0.60 mL, so each pump is roughly 0.15 mL. The dosing table says the same: 4 pumps (0.60 mL) once daily.
The serving volume drives how long a 60 mL bottle lasts, and the site's own figures on this do not agree. See the bottle-math posts.
