PA won't reveal what the proper dosage is, even under torture (Yes I have tortured him and he would not tell me the amount of sprays per day). But I have been told by his top two reps that 50 sprays is the optimal or max dosage on the sprays. Then again its not like you need to max out the product, we take less or more than the recommended dosage on all these supps anyways. I like 35-40 sprays (40 is best) because it lasts 6 weeks as opposed to 4 weeks at 50. And its "almost 50" anyways, plus a bonus two weeks.
