Benzylpiperazine
Benzylpiperazine (BZP), also known as 1-benzylpiperazine, is a substance often used as a recreational drug and is known to have euphoriant and stimulant properties. Several studies conducted between 2000 and 2011 found that the effects of BZP are similar to amphetamine, although BZP's dosage is roughly 10 times higher by weight.
