For pit sweat you need to go to the Drug Store and pick up an anti perspirant called certain dri.

I used it in High School when I used to sweat like a motherfucker... You still use normal deodorant, you put this stuff on at night, it kinda itches, but it really worked well for me.
I don't know if it was me, or the deodorant..but i don't even need it any more. I hardly sweat at all if I'm not running around...
Check it out...it seriously works.
