That is a cool video. It epitomizes what some people's ultimate goal is - To be massive, tight, pumped, juiced to the gills - test, GH and orals all flowing through the body creating a massive pump. Training, eating, sleeping, getting stared at whereever you go. Not being able to fit into normal clothes, and complaining about it (but secretly enjoying it)
I have never been that big, but I know a few guys who have, so I know what it takes to be like that.
Let me tell you, guys at that point in a budybuilder's life, it feels GREAT! But the only problem is, that it does not last forever, and you need an exit strategy, both mentally, physically, and possibly from a legal perspective also.
