Either follow the Culter break suggestion or take my word on this. We used the EPFX to see when Wilson's disease was in the Red then stopped until it dropped.
Cycles where usually 5-7days on and two-3 days off. Once we added Moly and Cuprum we could extend that. Once we could take MSM and NAC regularly there no longer was any need to stop.
NAC binds all bio-unavailable copper
MSM binds to excess copper
Moly bind to this parasite/tapeworm toxin bound with copper but will take out all the other forms as well.
best is 3x, when dowsing suggests you take a dose you are high in copper, else if after taking a dose you feel better same deal.
Best in Pellets 3x (we used Boiron) that way one Pellet will be enough. Actually most used Boiron I made my own with the EPFX can be made with any Radionic Potentiser.
