Who uses a compounding pharmacy? Which treatment? Liquid, powder or paste? Length of treatment? Cost of treatment? Results?

My favorite:  Diclazuril/Vit E / Levamisole, liquid. oral , 30-60 days. Very effective.

I think you've got to have the vitamin E and levamisole (immune stim) to have it work good. 
which compounding pharmacy depends on which one your bet uses. Nexgen is very good

Toltrazuril iis cheap and very popular but I don't see it work very often.

Most of mine that are hauling are on MVP Eclipse Pm , which has immune stumlants and muscle recovery along with cinchona barl extract (antiprotozoal). This product has greatly decreased the amount of EPM that I have to treat .
