If you want to double your gains then double your dose.

while i agree that for an experienced lifter 20-30 lbs in a cycle is very tough to accomplish. ronnie coleman put on 50lbs in a year (03-04) went from 247 on stage to 297.
yates put on about 25lbs in about the same amount of time.
not saying this is the case for most people, but some experienced lifters have managed to make incredible gains as well.

i didn't have time to read thru all the crap.. but if this has been mentioned already.. sorry:

ANYONE gaining 20-30lbs off a cycle, SHOULD NOT being juicing in the first place!!! That just means your lazy and are not anywhere near your genetic limit. 'Nuff Said

I'm just saying juice should be used to exceed your genetic limits.
