As the day has gone on, there is no comparison. I am herxing way harder than last week, same treatment for lyme, the Bionic 30 minutes with nosodes last week, the PE1, five minutes this week=a much stronger herx than the Bionic by far with less time. Less time, more herxing=more power. It makes sense, larger bulbs, 3mm Bionic, 5mm PE1, 880 nanohertz like the Bionic with 4 other wavelengths (nanohertz). Troy
