I would say a little bit of turn up the heat, or one or two sprays of ammo, in addition to ih. But there is still a chance to offend her, if she is not interested in you, which might cost you the friendship. So don’t do anything extreme and go slowly, both in pheromone and in your actions 
2sprays of ammo 1 tuth and some instant of your favor
Not what, but how.
Read over the product description of tuth.
Since you mention existing rapport, start with a single spray of ammo. As the evening wears on, add a single spray of tuth. Perhaps later in the evening another.
There should be a gradual change of mood. The lady should think it’s her idea.
Quite different from applying the product all at once, walking up to her, and slamming her in the face with an agressive pheromone signature.
