The theory is that post cycle therapy (pct) aids in recovery , and the time needed for this task (aiding) is 4-6 weeks.. But then u ll need time to recover and give your body some time to depend on its own.
That's exactly why the golden rule of cycling came at the first place
Time off = time on + post cycle therapy (pct)
If we recover directly after a post cycle therapy (pct) then we are good to go for another cycle after post cycle therapy (pct) directly but that is not the case..
