There are hundreds of research chemicals. We're not going to give you a list because the list would be massive and that's not what we do here. Bluelight is a harm reduction website, not a drug recommendation website or a legal advice service. If you have a question about a specific research chemical, that would be different.
Do a Google search, look on Erowid and Wikipedia, and read through the hundreds of threads on the various RCs here on Bluelight.
I'm going to close this thread because there's no HR question here. Please read the posting guidelines.
