Hello Karl, welcome to the forums!
Ammo as well as Shine are two very effective mones, though if you dont mind me asking, why did you choose ammo in the double strength? I only bring this up because ammo in the 2x strength is not usually recommended to men until they have begin to age a bit and natural production of none has started to decrease. Also a heavy hitting none signature can scare off some younger women. You may want to start with only a half spray.
Personally I haven’t found any disadvantages, well it certainly is a bit of a disadvantage to those not using mones. For you though, assuming you dont OD on none by applying too much I can see nothing but positive things in your future. Your choices for your next order are quite nice as well, IH is something I use quite often and I have found to be very effective. A314 I save for more special occasions, but it is extremely powerful as well.
You might want to check out this thread if you haven’t already.There is also on on ODing on none that I think I have bookmarked somewhere, I’ll link it if I can find it.
