This for mostly the newbies but I can atest to what alot of guys are saying without proper rest and food intake juice is worthless! I used to work 2 jobs and maybe got 3 hrs of sleep and did'nt gain much off the cycles I was doing at the time--Also there have been times where I just could'nt afford the food intake I was needed at 270lbs so I would struggle to keep my calories up and it totaly ruined a cycle for me-- Most of those days are in the past now and I have gained huge amounts but remeber don't do steroids if you don't have the money to eat of the time to sleep with a family at home......
