We have great success with the Plan. We've been focusing on the treatment of fungal candida for over 25 years.
Agrisept is much more effective as an anti-parasitic product or a general overall natural antibiotic. I don't use it to treat fungal candida, as undecenoic acid is much more effective and also addresses biofilms. Agrisept won't strengthen the fungus or cause it to mutate.
I always address fungal candida first and parasites afterward, unless there's a severe parasite infection that is in the blood stream. Even then, I'll use the Agrisept for 2-3 weeks just to knock it out of the blood, then use the Plan, and come back to Agrisept afterward. Balancing candida, the bacterial flora, and the immune response first goes a long way to ensuring a more successful treatment of parasites later.
