I feel like if insurance companies started paying for gym memberships or giving a discount on them, it would attract to people to become more active. Customers who exercise regularly are generally less likely to suffer from costly medical ailments including diabetes and heart disease. So discounting gym memberships pays off for insurance companies over time.

Hey mark recently my sisters teacher told her that protein supplements cause kidney and liver damage. While I know this is wrong I don't know why it is wrong or where the misconception comes from or if there is truly any validity to it. Thanks for all the work you do and i hope you have a good day.

For example i bought Fenugreek to add to my Test stack & was told i got the wrong type. So with so many forms & so many ways to extract that ingredient, seed,leaf,root,etc. How does the consumer know when he/she is getting the right form,extracted the right way?

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?
