My honest opinion of Zyzz,
First off, until he died I didn't realize he existed.
His physique seems to have inspired a lot of people to train, that's great. My personal opinion is he wasn't really that good for a guy who juiced to get there, he is small I think, yes he still looks bloody good, I'm not saying he had a crappy body. I just think he was kinda small and that you could definitely get to his size naturally if you are of the same height or similar etc.
His definition is outstanding and personally I wouldn't want to be that cut, nore do I think I could ever diet my fat arse down that low without feeling like dieing LOL. He has definitely left his mark on the younger blokes out in internet world, but his antics from what I've seen have mostly made him disregarded by the general population of the BB community. Overall, he had a great body, but in my opinion was a little to cut and not that big for a juicer. I can say however, that trying to achieve a similar body to him would be a great goal to strive for if that's what you want, he may be dead now and fame or infamy has followed him, but if you look up to his physique, go for it mate, you can accomplish that for sure, just be determined as fuck and you will do it.
