I did not see PZI on the insulin category so I am posting the question here. We have BCP Veterinary Pharmacy right here in Houston and they are compounding the 100% bovine PZI. Since we are not starting insulin til Wednesday I am on the fence about PZI vs Lantus. While Lantus has shown to have a higher percentage of remission on early diagnosed cases, the BCP PZI has also good readings. Have any of you had success or heard anything of the BCP PZI? According to artcles this insulin is the closest (molecularly) to feline insulin. Thoughts?
