What's the strongest antiperspirant available?

So I have pretty much diagnosed myself with having hyperhidrosis. I don’t just sweat when I’m hot, or mad, or stressed, but I also sweat when I’m cold and other things cause me to sweat that shouldn’t. I know I’m only 19 and my body is changing or whatever, but I found out recently that my birth mum (who is 34) still sweats a lot.

I was wondering which deodorant (non prescribed) brand is the strongest. I’ve tried many types, even men’s extra strength antiperspirant but I still sweat. I have even let the deodorant dry for an hour+ and I STILL sweat excessively.

If the suggestions don’t work I will be seeing my doctor about it, but I would rather try out something first before spending a lot of money seeing the doctor and buying something prescribed.
