My initial experience with P83 was not positive - at least for the self-effects:
P83 Self-Effects - Heightened Aggression
It turned me into one grumpy SOB.
I’ve since mixed it into feminine enhancer/activator mixes for my lady friends to wear. These are most A-nols and copulins with dash of P83 to stimulate action on their part.
Something seems to work since I a happy and tired man after my visits.
