Ok today i tried out that inhaler i had, amazing shit if you ask me. I was very focused the whole time and didn't run out of breath like i usually do on the last 2 reps or so, great stamina booster and keeps you focused. Took 4 puffs before i went then 3 more after first 2 exercises then 2 more after that when it wore off again. Thinkin about getting some tabs or liquid once the inhaler is gone.
