Well it will vary depending on lengths of the cycles. The recommended time on plus pct = time off. I think those are somewhat arbitrary and quite simply made up. Blood work is how you determine recovery.
So say you run 12 week cycles of test cyp
12 weeks on + 2 weeks waiting + 4 weeks PCT = 18 weeks on
18 weeks off
You now have 16 weeks left in the year.
Another 12 weeks on plus 2 weeks waiting and 4 weeks pct puts you into the next year.
I don't think anyone is following the broscience rules :/
