My brother has insulin dependant diabetes and is wondering why he isn’t able to take stimulants like caffeine and ephedrine pre workout?

you said it. its because he has diabetes. thermogens would increase BMR. doctors calculate insulin orders based on certain criteria in an effort to figure out what a normal day would be. so if your bro takes thermogens, he burns off a ton of sugar as energy and then we have insulin cruising around looking for any sugar it can find, and it will swipe it from anywhere including brain. he may be able to get around this by doing some experiments as to see how much less insulin he needs on days when he exercises vigorously,
