Pavel Dohnal – Brno, 56 years (immunity boost)
I have a six-year experience with Penoxal (previously Biocol) and I can say it works great for boosting the immunity. Since then I have had no flu or viral infections such as a cold or cough, not even during the flu season. I take Penoxal twice a year for about 2-3 months, preferably in the autumn and winter season.
Even though our family has no predispositions to cancer, I do not underestimate prevention and keep my immunity healthy.
