How many times a year is it safe for the average guy to juice? I did a three week cycle late July-early August and gained about 15 lbs. I did not do proper research at the time and never had a pct, still kept the most weight and strength though. I started another cycle two months later but a few days in my lower back around the kidney area burned awfully so I stopped and really loaded up with water, in a few days it went away and I havent tried since.
