The problem with PM is that there's no agreement on what a suitable dose is. Some people have been critical of some brands for recommending the amounts they do and yet in some cases the amounts they recommend seem low anyway, compared to other brands at any rate. Given that there's no agreement on dosage, it's really inevitable that the sizes sold are going to vary considerably, but having said that the smaller capsules sizes are arguably better as it makes it easy to tweak your own dosage.
