I wish I could get my hands on 2C-B. Too bad the RC scene is pretty hush hush nowdays, but I can understand why. This makes finding a reliable source (non U.S.) really really hard. 
I did get to try 4-HO-DiPT once though. Out of curiousity, Lars, have you ever tried this? You seem the most likely person here. If so, what did you think?
Haven't tried that no, only did 5-meo-DiPT and 2c-b of the research chemicals. If it's anything like 5-meo-dipt though, you should be very prepared. It was the toughest trip I ever had, borderline bad. It was a real struggle, but still pretty amazing.
Yea, I don't see the thrill in GHB. Can't take it alone or you could pass out and never wake up, can't take it with friends or you'll wake up with several penises drawn on your face.
Seeing as GHB is used as sleeping medicine, passing out is the medical point of GHB. It's not very dangerous except when mixed with alcohol or taken in liquid form (it's typical the salt gathers and the bottom and your final hit of GHB just might be as big as the total you've taken all night).
If doing GHB, take it in salt form, not liquid.
2c-b, whats that like?
Taken nasally, it's kind of like LSD with the duration cut in half, (every part is cut in half), with maybe one fifth the mindfuck and double the visual (considering a nasal 2c-b dose of 15-20mg versus an LSD dose of 150-200micro). And then add a euphoric edge and a horrible coming-up.
