Humans will sweat, even with using underarm products, so I think the best thing to do is to take care of the shirts before they get stained, and by this I mean that after wearing the shirt and tossing it into the wash to spritz the armpit of the shirt with white vinegar, or an premade enzyme spray product from day one BEFORE the stain develops.
For all of the other shirts that are stained, I’ve heard that white vinegar will remove the stains, and also a paste made from baking soda. Here is a link for different types of fabrics/leather etc
I’d try an ANTI-PERSPERANT, which helps control the amount of perspiration.
Deodorants only cover up the odor…not prevent perspiration.
DEODORANT BUT TRY NOT NOT TO BE IN HOT AREAS OR PLACES UNCOMFORTABLE
