The bottom line here concerning roid use is that it is not how much you use, but rather how many androgen receptors you are born with.
Some people can take a little bit of juice and simply explode. I know a former pro BBer who never took more than 400mg test and 400mg weekly from his teenage years, to the time he won the nationals, to all his competitions. when he came back to compete in teh Masters O a couple years ago, he had not touched juice in about 5 years and he still did the same cycle with GH thrown in the last three weeks and he gained 22 pounds of muscle in five months. I think we know what three weeks of GH will do. Nothing.
Paul Baker here in Ft Lauderdale, IFBB pro, take 600mg test cyp weekly year around. This dude easily weighs 320 pounds off season.
