It's your opinion to say that one is not ready to cycle when not reached the natural limit. I don't share that opinion.
Some may do, but there are also people who say gaining big amounts of muscle is useless and that bodybuilding itself is useless.

It's all a matter of opinion.

Try to look at it from my view, instead of saying what you've been told.
I've been training for a few years since 2003, got a shoulder injury, lost all of the muscle I gained and couldn't train for about 2 years.
That's been an investment of eating shitty bb food till the injury and spending a lot of time and money (gh) on recovery. Nothing in return for my time and effort!
I'm running impatient.
