Haha, bully my dear, that is because the shipping version of Ammo is 1.0, which contains mostly those three mentioned molecules.
Ammo v1.5 is a version that contains some TAA.

These haven’t been in vogue since before we even had to go’s available on the site, so maybe some newbies might like to try different flavors of Ammo.
Off the top of my head,I don’t even know the differences between them, ratio/pheromone-wise. So don’t ask!
