That’s about it. IO is a product where you can see some far more profound effects using about 4-6 sprays. At that level, you’re probably getting to about 50 mcg of Alpha Androstenol. And, at that level, it even starts to get a bit spacey. If you use enough IO, conversation should require little effort. Be willing to use 4 or more sprays. However, it’s worth it. The combination of say 4 sprays IO and 4 IH can be very interesting. The Beta Androstenol and third steering pheromone in IH is widely thought to create very deep bonding going beyond conversation. There are also some threads that deal with women attracting women sexually.
