I'm writing this post because there seams to be a rampid misconception that just because Piperzine its self (the precursor to recreational piperzines) is an insecticide then they all must be usefull as one. This is not the case. Piperzine is a usful as one because it causes the relese of a GABA related chemical that limits the amount of synapses in the CNS, enough this and you'll stop breating. Most recreational piperzines have the oposite effect on the GABA recepter, which gives them there stimulent effect. The only one that seams to have the negative effect of piperzine is PFPP. if any one ellse has any information on this please do post it.
