how long do they last? about how many sprays, roughly?
This has been covered in the forum and is in the Mens Phero guide complete with pictures. Link below in my signature.
To go bottles have 40 sprays
30 ML bottles have 200 sprays.
Go to each section of the forum, read all the sticky posts. Most basic information you need is written there. Then ask questions on what is not covered

This is just the information I was looking for. By the way, I’m new. I just signed up for this forum, because I want to get a bunch of to-go bottles to test out the products. I was under the impression that they would have only 10 sprays or so (the product photos on the Androtics Direct website looked kind of small). But 40 is so much better! Thanks again for the info.
Yes, 40 is good! HOWEVER, it also depends on your usage and on how much you’ll need for your own self to see results. Still a GREAT deal though!
