Amazon.com: Lilly Humulin N Insulin U-100 - 10 Ml Vial: Health & Personal Care
sorry if this counts as a source
I think you would want to buy the R not N. And don't mess with insulin unless you really know what you are doing/ are extremely strict about your plans.
You should probably go back and research a little more and find a vet that can mentor you a little bit. Stronger4Ever basicly just saved your life.
