Topical MD6

I was looking through this and found a topic
that discussed briefly on topical fat burners.
It said something about someone putting MD6
on topically. I was wondering if it was a good idea to do this? If so, should I use
androsol? or is DMSO okay? Other than
Yohimbine HCL going in, how will the other
agents work? like caffeine and ephedrine
and etc. Will it be bad to have them on
topically? maybe cause a rash?
Please give me some info on this.
