That's too unique of an example. I wouldn't smoke before such test, but only because I'd rather be preparing and sleeping, not because I think my mind would be altered, maybe if I spent the whole previous day smoking, but if that night I had a couple hits, I'm sure I'd be fine.
I also wouldn't run a marathon before the test so I wouldn't be too exhausted to think clearly, but I wouldn't say a marathon is bad for you any other time.
That's such an awful example. I wouldn't do it, but it has nothing to do with a hypothetical "pot fog." I can think of tons of reasons not to, and none have anything to do with the morning of.
GH prevents me from getting fat, but i haven't been helping it much lately.
now that my semester is over im gonna hit the gym hard and get my diet in order.
since i had my gyno surgery my training and diet have been garbage. partially because i was out of the gym for 2 months, and partially because my gyno made me insecure and train harder to make it not noticeable lol
