yes actually, baytril and amakacin never worked for me, in fact i got no positive results from either. Fortaz worked the best of all, it cured my snakes within a month. it is pretty good stuff. you do have to freeze it though. and the capsule you are using must be refrigerated, as the other two will be in the freezer. each capsule is good for 10 treatments or so. one injection every three days. and they should give you 3 capsules of it. the vet will tell you how much to give to the snake based on its weight.
