I believe Doug Miller is "natural" if by natural you mean he isn't using ILLEGAL drugs or those that you need a script for...
But the guy takes a thousand different pills that you can buy in any health food store. Testosterone boosters, P-slin (some knock off of insulin im sure) etc... I'm sure half the things he takes, are probably LESS healthy for him, than tried and true gear, but to each their own.
I dont see why so many people doubt this guy.
