The compliment probably was caused by the pheromones, even if it was not directed to you.
For me mx135 has a subtle even calm everything is ok self effect. It doesn’t have the bang that instant sexiness has unless they are very reactive to tah from what I’ve noticed. But it does have a lot more to it than just tah, a recent post by Jasmin described it as a kitchen sink mix with a little bit of everything.
A lot of posts report better results using instant sexiness and mx135 in tandem.
