I'm trying right now very hard not to say anything I will regret........ I'd say polite way - please don't experiment with a frog, not now, not ever!

go to a vet, any vet, and ask for panacur, every single vet in a city would have it. it is used very widely in every practice for every single animal, just different dosage. Or email Dr. Frye and get exactly what you need for your frog instead of ordering from amazon or elsewhere. I believe his clinic ships anywhere in US to be delivered in a matter of days.
