I think a good idea to mix different supplements before capping would be a ball mill:
high end: http://www.retsch.co...CFU4e3godBFiuDA
low end: http://www.unitednuclear.com/mills.htm
Anyone using stuff like that?
With ceramic or glass grinding media there should be almost no contamination.
I think it would be especially nice for the Resveratrol crowd, because they wouldn't even need micronized Resveratrol, just keep the ball mill running for a week or so. Mixing with stuff like Tween80 would probably also work better.
