M20 still can't find an antiperspirant that actually works

I've tried so many different deodorants and sometimes they'll work for maybe a month or so, then it seems like they just stop working.

I usually take a shower, then once I cool/dry off I put on deodorant, but no matter how it do it, it always just melts off and it's really frustrating.

Most of the time I don't think I smell too bad, but there are definitely times where it just does absolutely nothing.

What is the strongest/most effective deodorant you know of? I don't care what crap is in it, I just want something that works.

Thanks!
