Ding, some of us nattys are bloated in the offseason. Shit i have thick skin and acne all year round. My testosterone has been tested twice and its stupid high. But a high test level also comes with estrogen which causes some of those effects. Hes not nearly big enuff to be a juicer even part time.
He did say that he has to diet 22 weeks so hes cant be to lean naturally. Some of us are not natural "Ab-shooters" LOL. 
Ok bro, I see your point, and for the most part I'm sure he is natural. But, have you ever seen pictures of him when he's not cut? It looks more like water retention than fat, reminds me of someone who just got on something like dbol. I won't say he's not natural, he may very well be, I just personally think he hits a few of the goodies that clear your system within a day, and possibly some GH for leanness.
