Are there any deodorants stronger than "clinical strength"?

Something about my body chemistry changed when I lost a lot of weight an regular strength deodorants do not work for me at all. Only some of the clinical strength deodorants work for me for an entire day and I am finding that even those are not reliable when it is hot outside.

Is there something out there, maybe something natural, that works better than “clinical strength” Secret, Degree, Dove, etc.?
