you liked them? i was under the impression that they suck. i was told by someone it's a speedy chemical with no empathy or loved up feelings like MDMA. my friends have reported terrible comedowns with a hangover type feeling the next day from transformers. in my area BZP/tmfpp pills are called "bunk" or "garbage". supposedly its a cheap legal alternative to X in europe. in the US/Canada they press it in pills to fool people into thinking they are rolling. its cheaper to manufacture or acquire than real MDMA- which there is no "substitute" for.
Well, I took it it a show so I was naturally pumped anyways. But I was pretty fucked up. I had a really good time.
