today I tried p.e.p pills from a shop in London. He popped 2 (which is what he was sold in a single container at about 12.30pm (no other drugs were used and no other drugs had been consumed for 48hours). The active ingredient was Piperine and Piperazine. After 1 hour of ingestion he felt a definate shift in perception, not a huge great rush or anything but definately "something" different. He yawned a lot and noticed his eyes water when he did (this was almost a mimic of the sensation sometimes felt on XTC). He was consious that his behaviour was slightly different (almost paranoid that he might look a little stoned) and felt a tiny bit giggly or happy (but this may have just been the usual interaction with people). The whole experience lasted 5 or so hours after which he had a bit of a headache. All in all he reported that the experience was generally quite good and rather surprising given previous experiences with most other "legal" highs. He said he would try them again, maybe try the maximum stated dose of 3 pills.
