MX428 - Read the thread, use on its own and post your findings.
Thne, after solo testing, you can do what you like with it and as MX428 is TAA-based like IS, yes it will likely go very well with Ammo.
The 2x strength Ammo is maybe too much for your age, unless you produce an unusually low level of none. 1-2 sprays standard Ammo is about normal for your age and 1 is most usual. You need to do some testing to work out. Mind you, you could dilute the 2x 50/50 with cologne or even the MX428 to bring its strength down or if you press carefully, it is possible to get approx half sprays from togos and bottles.
