High on a big dose of poppies + 2.4g gabapentin + 125mg diphenhydramine to increase the effects and 60mg pfpp+70mg tfmpp to make it a bit trippy. Actually got quite a bit of visuals and a bit of a psychedelic mindstate. Nothing like a good dose of doc, lsd, or any other strong psychedelic though.
I've heard so much about bad side effects from piperazines, but I have not yet experienced anything worse than mild nausea and sometimes a bit of next day tiredness. They're no substitute for mdma or strong psychedelics though. Just good for getting high and killing time.
BZP is good for energy and would probably be good for studying.
I accidentally got some pfpp under my tongue, and it made blisters. It was only in contact for 5 or 6 seconds. From now on, it goes in capsules. Some fool will probably try to snort it some day. They'll be in for a world of pain.
