Yes, this is something I would like to know for the future.
I figured the mg would be the amount of powder but would it be made more watery or more like paste? I imagine giardia parasites would be the only thing it would be used for. This is the biggest cause of runny feces or loss of appetite. I would like to have some on hand if its ever needed but I was unsure of the proper preparation. All the info I have found is vague.
Another thing that bothers me is how most dosages for medications are measured in kg. We weigh our animals in grams. I wish there was a site with more detailed information for reptiles in these cases.
