I'm going to attempt some math here. It won't be 100% accurate, but it'll be a good guestimate as to how many sprays you can get out of it. Let's say the average fragrance atomizer disperses 10-12 sprays per ml. Your bottle is a 50 ml bottle, 50ml x 10 = 500 sprays and 50ml x 12 = 600 sprays. You spray 3 times per application, so 500/3 = 166.6 wearings and 600/3 =200 wearings. If you were to wear 3 sprays of Aventus every day, you could wear it approximately 167-200 times, or roughly 5-7 months.
