I have tried the different models and the effect of Godzilla is simply tremendous compared to others. If you are after stomach parasites just zill your stomach 15 minutes every other day and you won´t notice them again. If blood-bourne amoebas etc you´ll need maybe 2 hrs per day for 2 weeks to kill off the whole lot. In addition I sleep better after zilling my blood.
I´d say take it carefully when applying Godzilla on the stomach of your kids because the die-offs may be massive 48 hrs after zilling. That happened to me so now I do everything in small doses increasing doses week by week slowly, parasite cleanse, liver flush, Godzilla, salty baths etc.
