Welcome to pherotalk Tabu!
Instant sexiness/a has been discontinued and MX300 is no longer available as with most experimental mixes are introduced and there is no guarantee it will remain in the store.
These two threads should assist you as to why :
MX397 is new and we are still reporting it was not made to be like instant sexiness/a but we are trying to produce experimental mixes that give similar results and are even better.
To get you started I recommend the socials and trying out is/b that will make you feel comfortable in your skin.
The experimentals will come later when you know what pheromones can do, the practical side of it.
