I know 3 weeks is optimum for gains, but I also see most people start having sides in the 3rd week. I agree with the argument of keeping it down to 3 weeks, but what is the reason for not doing short 2 week cycles. It would seem you would be able to reduce sides, and fit more "mini" cycles in with less threat to your health. Albiet the gains would not be as much but I'm trying to look at the big picture and maximize gains for the long haul and keep my liver in tact.
Any thoughts or data?
