Personally I'd never buy anything sold as pellets or pills. They could very easily be pressed with multiple chemicals. Though I know powder can be mixed as well, I personally feel much better about taking an RC when it's straight from powder. Psychological? Definitely. But hell, if it makes me feel better and safer doing it, why the hell not, right?
If you're looking to save time dosing, just measure out doses before taking the drug. I'd do something like, several 20mg doses, a few 35mg doses. Hell, maybe even two or 3 50mg doses. Who knows.
