P83 definitely brings me to life but it is always accompanied with my libido cutting loose. :o I have been using 2.5 mcg per spray and using between 1-5 sprays. The vibe is nothing short of sex crazed I hit on all girls I come in contact with. I have worn it by itself ,with Ammo , and with IShine. Androstenone makes me pissed not really turned on.
