I think Blakely is a fine example of the "those who have eyes to see" dynamic, present in almost every aspect of strength and physique training. A natural who doesn't understand the mind numbing drug doses that went along with the gastronomical feats of heroism will turn to an absolute tub of lard within no time at all if stupid enough to emulate Blakely's drug inflamed metabolism.
Trying to out eat the 5+ grams of test (and who knows what else) that lifters of that level have typically used as a base (assuming guys like Ryan Kennelly and Mark Bell can be believed), takes an all-consuming, 24 hour a day commitment and even then stored bodyfat is surprisingly low all things considered.
