Did anybody tried PFPP? I know a lot of people don't like piperazines effects especially for their negative cause effects, but I heard many good reviews about PFPP. Peoples described effects PFPP like mix of small doses of mdma and lsd or mushrooms with almost no negative parts of feeling knows from other pips (it's mean no uncomfortable stimulation, no nausea and hard comedown). Doses are from 20 to 80mg. Duration 5+ hours. Effect's are depended of dose and small amounts of pfpp produce mild, social-extasy like feeling ; big dose induce vision-state like mushrooms or lsd of course in pfpp-own way.
the 2 pipers i've tried are tfmpp and bzp, and i found both of them to be pretty pleasant to be honest. though it's fucked up that they're sold as mdma. i don't have any experience with PFPP, though if i had the opportunity I would try it..
