Antiperspirant Mitchum Help?

I seem to have a problem with perspiration. I always sweat, everyday. Its really annoying, and I hate have sweat stains on my shirt. I have Adidas Antiperspirant Sport deodorant but it just seems to stick to my skin and then get wiped of as my shirt rubs at it through the day. I also have Mitchum Sport (I play sports a lot.) gel deodorant, which is supposed to be a really good antiperspirant, but when i put it on it just sit in my armpits and will normally get wiped of by my shirt when I put it on. What should I do?
