Hi Mark! What is your opinion on cycling calories throughout the week? I have a very busy work schedule and I usually under eat the days I go to the gym but make up for them on my rest days. Will this affect body composition? (Since I eat more calories on rest days and less calories on training days)

I've heard you mention them briefly, and i know you're not a fan of PH, but what is your overall opinion of the 1-andro and 4-andro products that seem to be blowing up the market right now?

I'm wondering would using a Training Mask be any beneficial to any workout ? 

Hi Marc, in you recent videos you are advocating on squatting everyday, what squat routine would you recommend? would you do the squats before or after your workout? would you change the types of squats done for example one day overhead squats, and another day back squats?

Thanks for you time.

Josh
