you have that many posts here and youre unfamiliar with pipes?
Piperazines are a type of drug. Manufacturers decide to save money and take less risk so they press piperazines into pills instead of MDMA (legit ecstasy). Uninformed people still buy them. Some people get similar effects that MDMA gives you but they are pretty much crap.
pipes are terrible, no peak, just a steady kinda buzz and a shit comedown...from what i have seen they are usually shaped like something..ie transformers
Piperazine is commonly used in place of MDMA in pills- it only intially feels similar to MDMA, like you're "coming up"...I'm not certain , but I've been told piperazine is used in place because the components to make it aren't as closely tracked as MDMA, and it's much cheaper.
Fortunately because testing kits are available, and websites like pillreports focos on spreading information through community contributions, "pipers" won't get sold as easily because users will be educated.
For the record I've gotten piperazine once- took one pill (and two other actual MDMA pills that night) and it SUCKS.
You mean piperazines. Substituted piperazines are actually a family of chemicals, and many differ from one another (but none are particularly well-received as recreational drugs).
