Hi Jhan
I have used nystatin powder both orally and in a retention enema.
It produces enormous die off. I had to ease off due to liver and kidney issues.
Just search nystatin in the little search bar at the far left hand corner of the page. It comes in different amounts of "units". I bought the 100MU and that was about a 1 month supply.
THe dose is about a 1/4 tsp. Only a little is needed. YOu do not need a prescription for this site. The quality was good and it is in powder form and no Sugar added.
