I keep telling my experience with the Biotrohn. I have used it for Covid 19; one session with program 6 (viral flu) and 4 sessions with 36 (coronavirus). Two daily sessions, two days. cured!
Tested on women. Urine infection with some bleeding. Four sessions (two programs a day, for two days). Program 27 (urinary infection) and on the third day, normal urination, almost no symptoms. On the fourth day, absolute normality. I continue to use it with program 1 (universal) and 93 (arthritis) with very satisfactory results.
