I just bought a few bottles but it doesn`t really tell you how long a bottle will last...just 8-12 sprays per application. I am guessing the maximum is 12 sprays x 2 per day would be around 12 days, but I don`t know.
The andro spray at 10-12 sprays per day should last between 3 1/2 - 4 weeks for the bottle. Obviously if your doing multiple daily applications, that will lessen the length of the bottle.
where do you guys spray for best results? i would think back and chest since those are pretty big muscle groups. isn't that the best place for absorption? what about thighs or abs?
I was told to spray places where you have visible veins (ie top of hand, forearm, top of foot). Also, I was told the top of the chest is good as well. I spray a little in all the areas above just to make sure I cover all bases. So far, I really like this product (Andro Spray). Good luck.
