Only time I tried amps were *likely* as bi-products of the cheap MDMA I bought back in the day. Always hated the "speedy" feeling. The only acceptable stimulant to me was pure coke, and it was not always easy to get pure. Then again, even that wasn't my scene. I was really all about the psyches and the weed. Growing shrooms, hording LSD, smoking DMT, and experimenting with the odd trypts and phens was my deal (BTW, 4-AcO-DMT is the best overall psychedelic on earth). I had too many experiences with friends getting in trouble with/dying to/otherwise fucking up their lives with speedy drugs/opiates/benzos to care about them in any capacity. I haven't done anything for years, but no regrets. Edit: At one point, I had a legit "Fear and Loathing"-style briefcase. Many of the drugs I never did, and wound up tossing. The 2C series was profoundly interesting on a visual level, and relatively nice on a head-space one, but the body load (namely, blood pressure and chest pain) made them scary experiences. I wound up tossing many of them, but 2C-P scared me the most; 2C-I was profoundly intense visually and psychedelically, with a **bad** body load, lasting 10hrs. 2C-P was supposed to be much of the same, but 2-3x longer in duration. I definitely didn't want that experience, and was somewhat unsure I'd even survive it.
