I was a bit suspicious when he claimed 20 lbs in 3 months; usually 1 lb/week is considered the upper limit for beginners. Then I saw he was suggesting a high creatine intake, which for many people will cause them to retain water. I imagine a significant fraction of that 20 lbs is water weight, meaning it's easily lost when you stop taking supplements and working out for a little while. That said, the water is stored in your muscles, so it does make them look bigger. It's just not a permanent kind of gain.
