Here's what you need to do, Growin':
1) Sterilize your blender in an Autoclave fashion. I.E., pour boiling water in it and let it rip for a couple minutes. Replace water as it cools down with more boiling water, and boil all the small parts (blade, washers, etc.) in water for 15 minutes.
2) Add your complete Yohimburn mix into the blender after it's all dried up and sterilized.
3) Run the blender on LIQEUFY or the highest speed available for a good 1-5 minutes or until all clumps are gone.
And there you have it. Micronized, schmicronized. I've done this before with creatine, ALA, etc. and it works quite well to put any soluble mass into solution.
