I'm going with Sev and Gal's idea of getting lean first, THEN using.
But to be fair, the older I get the less interest I have in using again. What's the point of dropping 100s on chemicals when you're only going to end up losing most of your gains anyway when coming off. I'm not interest in staying 'on' all the time either. Maybe I should wait till I'm in my 40s and hit it naturally that next decade.
I'm not a 'bodybuilder' anyway. Now that I'm a natural and don't train for months, I get all my shape and size back within 2 weeks when I get back to it.
