i believe you should always add your pct to time on. Did you do pct, how? Add this time to your time on cycle . So eight week cycle, then like 4 weeks pct= 12 weeks take at least 12 weeks off.
I know its hard to wait between cycles, easy for me to say considering i just started mine, but my previous was 14 weeks then 5 weeks pct i waited 20 weeks for next cycle. And right at 20 weeks almost to the day, i started my next. Its hard not to juice.
