www.chemexper.com -> search 2,5-dimethoxy-4-iodophenethylamine chemexper is basically a search engine for RCs. The one's you find directly on there can be kind of sketchy but when you start typing the suppliers into undrug and Google you'll get plenty more vendors. The trick to RCs is a place to start and it's not really hard to do. I don't understand why people make it out like it's a long complex ordeal. Well, there you go. A place to start. This also works for other RCs. Just use chemical names (IE 5-methoxy-N,N-dimethyltryptamine, etc)
