If I were you(allthough my advice probably isnt the best because Ive never even SEEN an RC, let alone hear about someone selling/taking it) I would take each one of those drugs individually(one of them one day, another the next, etc..) and get to know each ones individual effects and how your body/mind responds to it. Then, after your confident in your understanding of the way these drugs affect you individually, only then, should you think about mixing them together to achieve a different effect....its all about knowledge, and experience.(and a dash of sommon sense)...it may be that none of these drugs shuld be mixed, or maybe, for you, it would have a nice effect in certain quantities.
Just be careful, and make sure you know EXACTLY what you are doing, and exactly what you expect to happen when mixing two or more drugs, based on your extensive research/experience from before.
