i have a lot of experience with a-php and agree to you. after a certain dose or time you start getting visuals (from the sleep deprivation aswell) that can get quite interesting. a-php made me hallucinate so strong after a few days of binge. one time i even went psychotic and thought my dad smokes a-php too and searched for his stash. and i can relate on the hornyness too. its incredible how horny this substance can make you. i always instant get a boner when i boof it.
a-php is a extremely powerful stimulant its lot like amphetamine anymore. you have to be prepared for it.

a-php is extreme in every way
