Strength varies to much to say. I'm a twink and i lift very heavy, it's part of the reason i want to stay natty to see what the limit is. It also depends on your goals, i don't like the overly juiced up look, so when i do go on in a few years, i would be looking at low dose test, var, hgh. If it's just a visual pursuit of a certain physique you might as well jump on now if you have the cash. It doesn't affect your ceiling, most pros are on in their early teens, it will affect what you go down to should you go off. Naturals who have paid their dues in the gym for years keep muscle far better regardless of circumstance.
