how long does MX353 last?

considering it’s scented.. is it supposed to be a cologne like ammo?

Ammo is a pheromone product with its own cologne scent.

How long the cologne scent lasts - ar lasts at a level you want - is probably very indidualistic but on me the cologne scent lasts as long as most good colognes do.

How long the pheromones last is also slightly individualistic and partially based on weather, etc. But you can count on them for at least a good 3-4 hours. Both products however do contain 'none (the “I am a Man” pheromone). 'None lasts much longer than just about any other phero and is very sticky. So when using MX353 you need to be aware that you will get 'none build-up.
