I did a FINA only cycle only for 4 weeks at a dosage of 50mg/day. I had no problem with getting wood, actually I was hornier than usual, the wife actually loved it. I had no side effects, except for insomnia and night sweats. I gained at least 15 pounds, I ate like a complete pig and even lost a bit of fat. Remember, I know this is basic info, but when doing juice, nutrition and sleep maximize your gains, training is important, but if you don't eat right, you won't see any major gains.
