BEEF PZI Insulins for Cats, Dogs, Horses and other non-human diabetics!

Pet Owners wishing to acquire BEEF PZI & other Beef insulins for pet care at more reasonable prices should contact CP Pharmaceuticals for instructions:

 CP Pharmaceuticals' Insulin Line: 011 800 667 55 555.

Because of calls from individuals wishing to import for cats, dogs, and other domesticated pets, I asked CP for instructions and they have advised me:

Dear Dave

Further to your e-mails, may I confirm that the procedures for obtaining CP's insulin for animal use are similar to the procedures for human use.

The only differences are that where you would normally require a letter from the licensed practitioner, we would need

1. a letter from a licensed Vet, stating that the insulins available in the U.S.A. do not effectively control the diabetes.

2. a statement from the owner of the Cat saying that the insulin is for their own felines use and that the number of vials being ordered is no more than six months supply.

3. the USDA Import permit is still necessary

4.  the completed CP order form.

Should you require any further information, please do not hesitate to contact us.

Kind regards

Tracy Davies


Hello to you both...

Here is a list of companies that make or compound PZI insulin for animal use. This, and beef Ultralente (which I haven't been able to find a list of suppliers for), are the forms of insulin of preference for use on canine and feline diabetics.

Please note that there is a wide range of prices. Hope this helps.

Best regards,

 Michel Martin

PZI Suppliers

Eli Lilly no longer makes PZI, but can give your vet a referral to someone who can obtain it. 888 885-4559  (They won't do this for people!) [We are now told that some of the Pet Vets' Pharmacists will compound for people! 11/20/2000]

  1. Blue Ridge Pharmacy
    North Carolina

    Blue Ridge is now the only pharmaceutical company manufacturing PZI rather than compounding it. Your vet needs to fax them consent forms, which I can e-mail to you. There is a minimum order of 3 vials of U40 PZI @ $174 (shipping included). Because this is manufactured, it has a shelf life of over a year, vs. only a few months for the compounded PZI.

    Important Note:
    FDA has reportedly stopped Doc's production.


    I just read your very helpful page on obtaining PZI insulin for cats and dogs.  I thought you may be interested to know that one of the suppliers listed, a compounding pharmacy, has had very serious problems with it's quality control.  In fact, a couple of people died from contaminated medications supplied by Doc's.  It may not even be in business any longer, but if it is, it should probably be a last choice for obtaining PZI.

There are a number of Vets compounding protamine zinc insulin in beef for  their clients here in the US. I've lost the names and Emails of the leaders  in this campaign and, regretably, CP won't/can't export for cats or dogs due  to the human needs and Biobras won't due to the FDA's and USDA's nonsensical  behavior on the issue. Unfortunately, I've lost the names of the activists  for animals due to HD crashes.

I am forwarding your Email bcc to a group of over 100 folks who may be able  to find us the leaders in the animal for animals work. Human UL may be your  best option in the short term but isn't likely a great solution.

Just wanted to let you know that BCP Veterinary Pharmacy in Houston, TX has reformulated Eli Lilly's old Pure beef pzi insulin and has excellent results. It comes in U100, U50, U40. The price is really great and there is no minimum order. Insulin is sent in insulated containers with ice packs.
