Like yourself long time ago i used products like the one you mentioned with NO results at all.
Then i found Androtics and everything changed
Now back to you
Its most likely to get ‘aggressive’ responses from ammo compared to A314.
Yea Ammo is user friendly with buffer to prevent -none OVERDOSE but it still contains -none (the most aggressive pheromone when used in larger mcg)
I suggest you give us more info about yourself and what are your expectations from the pheromones so we can suggest you a product to start with.
Usually A314 is not recommended for first time users but if the description suits your needs then go for it.
Here is a little help for the A314:
