P83 is not something you can use as a standalone I think, better paired with some other mones for steering yes.
Not convinced it is a crush putative, it’s way too blatant for that.
Can be used as a ‘booster’ in a crush mix to give the other mones some extra punch.
What it does basically: it creates disinhibtion in people. Paired with other mones hits are less than subtle!
Most reported hits are people invading your space (human velcro effect), and dirty talk. Helps with sealing the deal so to say.
Can also backfire if you use it with the wrong mix, or cause unwanted hits - read my latest journal post 
I recently bumped this thread, good info there: Putative P83
