stats for neutral monsters?

So they have the growth statistics and such for all the champions. Why not for all of the neutral monsters? I am noodling around with an idea, and would like accurate stats for all things in the game. The only thing I DON"T have is the details for neutral monsters. I know they get their level from the average level +1 at time of spawning and stay until respawn, but what are the stats at different levels?

I want Dragon and Baron, but Gromp and Red Bramblebacks too.

Anyone have a link or info they can share, I'd appreciate it.
