Is burst hydration effective? I drink about 2 liters in the morning during my workout and then don't drink much at all during the day at work. (7am-7pm) at night I drink another 2-3 liters to try and catch up. Is this type of hydration bursts where I drink a lot in a short period of time effective? Or am I just peeing all the excess water out without getting the benefits. 

Hey marc, I unfortunately took a lot of pro hormones in between the ages of 18-21. About 9 cycles to be exact. And I was stupid enough to even drink occasionally (sometimes to the point of being hammered) while taking them. I haven't taken anything at all in 3 years now and have just been putting in the work to make gains naturally. My question is in your opinion do you think I caused any permanent damage to my hormone levels or to my liver?? Sometimes I feel like I should be making better progress for the amount of work I put in and I wonder if it's because I have diminished hormone levels due to taking those bottles of false hopes. 

is supplementing with tyrosine bad for you on a long term? I take around 1.5 gr of tyrosine every day and i`ve read that tyrosine is kind of a stimulant and can have side effects on a long term is it true?

I've been tracking my REM sleep lately and have found that I get a minimal amount of it. How important do you think REM sleep is for optimal recovery from training?
