Pam Sessoms, an FHL moderator and FHL Librarian maintains a list of compounding pharmacies that people use. Many of them, like the one we use in NJ, ship. This list can be easily found in the FHL Files section: http://pets.groups.yahoo.com/group/ferrethealth/files/ The med amount is in mg so you find out how many mls are in the bottle, and since you know the dilution gets the concentration to 50 mgs in each of those mls you just go from there by multiplying the total ml amount the bottle originally had in it by 50 to give the total amount of medication you bought. So, you did not give enough information to know how much medication you are getting for your money. For the mg (medication) amount in each dose you just multiply the dose of 0.3 ml by the concentration: 0.3 ml x 50 mg ------- ml and the ml designation cancels out giving a dose amount of mgs that is 0.3 X 50. All too often people just give the ml amount of medication they are giving, but many medications come in multiple concentrations so the ml amount alone is usually pretty useless if they don't also give the concentration as you did above.
