Some of the rap guys shown have been famous for almost 15 years. There have been videos and pictures of them all that time. When the pictures showing them soft and out of shape for that period there's a smoking gun when they suddenly look buff. Don't tell me they just got a trainer and everything fell into place. Where there is smoke there is fire.
I have seen to many zeros look great going on their first 3 month cycle. The reality is that when they go completely off they go back to what they originally looked like. Hollywood type entertainers are filled with juicers. Even a lazy trainer can look somewhat decent using drugs. The hard thing is getting in shape juice free and staying there for most of your adult life.
