The issue is that KPV doesn’t have human clinical trials to establish a cycling schedule. The published research is largely cell and animal work. Eight weeks on and four to eight off gets repeated, but that isn’t a schedule proven in people. Some run it continuously; others finish a cycle and stop. IMO, nobody can confidently tell you the ideal time off yet.
KPV cycle time off
How long are people cycling on and off KPV? Looks like 4-8 weeks, but then how long are you taking off before starting again?
