Something we have done is have the vet write a prescription and get you the syringes. Then call around to local pharmacies and find it. It can be difficult to find, but is possible. We found a 1 gram vial for $23. REMEMBER, 1 gram is a huge amount, so if you are not familiar with reconstituting and dosing, make sure you get the Vet's help. I am a health care professioinal, and am more than comfortable dosing and reconstituting. Once reconstituted, I draw up all the doses and freeze them. I hope this is useful information.
