Just to add something for harm reduction...
Sounds like the OP is getting into messing around with research chems before he's even done the "regular" drugs that are about. This seems like madness to me. The reason you can buy these research chems online is that no one knows what they are, how they work or what damage they're doing to your body. They are potentially more damaging than the illegal drugs, the only reason they are legal is that they are so new no ones got round to making them illegal yet!
Taking any drug is always potentially dangerous but at least with mdma, coke, speed , lsd or whatever you might want to take you can read up on what these things are, the risks of doing them and make an informed decision about whether you want to take the risk of trying them.
With research chems they could be doing ANYTHING, and you could be doing yourself massive damage by doing them. As far as I'm concerned the people who get into research chems are people who are bored of every type of drug out there and are committed to their drug taking so are willing to take the (potentially massive) risks of the research chems.
Do yourself a favour and go do a load of research on the more regular drugs and experiment with them. I really don't think there's any need to mess around with research chems if your new to drugs.
