Hi every body,
I have a dose of a drug used in rats, and i want to use it in guinea pigs, how can i convert the dose

I guess checking with the mass of the body

You can go for body surface area conversion chart.

then also if you can't find out, give me detail about your study and doses, i will find it out for you.
