The full sized bottles apply more pheromones per spray. I think the togo’s have approximately 80% of the content of a normal spray.
In my travels P83 is very sexual, yet without a lot of the aggressiveness of none. It doesn’t seem to have a profound self affect, and doesn’t elicit abnormal behavior from other males. For a light touch 5mcg would be good to start, but it also ramps up nicely with more sprays. I like about 15-25, and others have had good reactions upwards at 60.
P86 supposedly mixes really well with P83. from what I gather it is more social than sexual, but I haven’t experimented with it too much myself yet.
