the entire generation of under 30's are on Adderall and stimulants.
back when I was there age if I had to study for a test, I studied for a test. now your generation has to take drugs just to be able to think. half of you guys have ADD (or atleast think you do).. when in fact there is nothing wrong with you, just that you are too damn lazy to get your shit done.
if you are already taking that crap just to workout, then it will come back to bite you hard when you get older.. remember I told you this. adrenal fatigue is a real thing. you WILL get addicted to it and you will have to use it everytime you walk into a gym .
