Ok Ive been reading the fourms but I haven’t seen any recogmended dosage charts I mean by age that is Im 18 I only go for 2 years up and 2 down so I would like to know where to start then tweak it from there ( still a noob btw)
No charts. It’s all up to you. Age can be a factor in how much you use, but like most other factors it’s too inconsistent for a chart. Most Androtics consumer products will have their best effects at between 1 and 4 or 5 sprays. When you get your order you’ll be tempted to just spray everything on and hope it works like an ax commercial. 
It probably won’t but you can try.
Best to try one product. Use it for several days. Try different amounts. Then take a day or two off. You should start picking up on how the pheromones affect those around you and will be able to determine your “sweet spot” dosage for each one. If you start combining products right away you’ll have no real idea of which one is doing what. Good pheromoning! Looking forward to seeing how it goes for you!
