Heath comes off or off everything except high HGH before going all in contest prep. He's smart
There's nothing "smart" about that, it's obvious concept and everyone knows its best approach but they just can't do that. Reason why they can't is simple - they are insecure, they can't stand the very thought of loosing their size. Some of them as well have to do something like "off season" because they have lagging bodyparts which they need to bring up and it won't happen over the course of like 20 week long contest prep.
Phil Heath has neither. He, almost like Levrone, doesn't give a fuck about looking "huge" all year round. Frankly, he doesn't have to be huge to look impressive, it's not his main weapon. He would look just as impressive at 190lbs, trust me.
Galeniko is 100% correct here, I'm astonished by the amount of idiots who can't grasp simple concept that if Phil Heath is "all drugs" then why does he win contests? Because his opponents are shit? Well, you can't blame him for that, can you?
