Gm150, Tom Brady is also very picky about what he eats and drinks.
Remember the interview he gave recently and pretty much trashed all the Gatorads, Powerades, etc, just about all energy drinks on the market because of their sugar content
Who knows?
Maybe someone he knows in or out of football gave him a bottle of HPD and he read the ingredients, was impressed, drank it, likes how it tastes, and felt the beneficial effects and told his agent to look into it.
And of course he is signed on with UA and we know of the UA-HPB connection.
Hey, stranger things can happen.
