I’m old school when it comes to PCT and actually think the 40/40/20/20 method works just fine, although there’s certainly no harm in stretching it out longer.
In week 12 you can drop to 0.25 EOD for your last couple doses then stop. Full disclosure - I’m on TRT, but if I had to PCT that is how I’d do it, just to match your falling test levels and avoid crashing E2.
