If I'm running test enth weeks 1-10, then that means I'm injecting something till week 10. Then I wait 2 weeks after the last inject to start PCT. I always run a short-acting compound the last 4-6 weeks of my cycles to lead into PCT these days. Say test weeks 1-10, winny weeks 8-12. PCT starts the day after winny stops, first day of week 13. PCT for me would be nolva 40mg/day week 13, and 20mg/day weeks 14 and 15.
