You obviously dont know how peds work and whats the role of genetics, nutrition, training...more doesn't mean better,after a specific amount it only has side effects and no advantage.Also you are talking bout the gift,look at him when he was natural,he was better than most guys in cycle...some respond better, they are made for bodybuilding as others are made for football, basketball etc
Its totally possible to get huge if you have great genetics with low doses. I do think alot of bodybuilders play their doses down, but if you respond well to aas then high copious amounts are not needed. One thing i will say is you need the hgh to amplify the aas effect . Again not necessarily high doses. That said an olympian low dose is still high for the a average joe.
