99 out of a 100 people can never achive those numbers naturally OR on juice.
I'm not trying to discourage anyone, but let's get realistic here...it doesnt matter how much of a hard worker you are, if you don't have above average genetics, and you want to stay natural, you'll never achieve those numbers.
I've been lifting for 14 years, have fairly decent genetics and have juiced and haven't hit all three of the above numbers together...I'm also extremely strong, stronger than most people I know. I'm a strength athlete.
Then again, weight and overall built make a diff. I'm only 5'8" and 205 lbs...if you were a 315 lbs farm boy, you will probably hit close to these numbers in 5-6 yrs of training and might even be able to do it naturally
