I know it is available on Amazon....It is the Safeguard Horse Wormer 25gms. Again, want to share that this is what quieted the scattered storm and helped the first large Rope exit...but I do not think it is the solve all. I do think Scabdraggr's protocol is the best med. base for the "broad spectrum" category of new species or resistant common ones; where the drugs of yesteryear are just not cutting it anymore.
