Hi, I was wondering if Cainsulin is available in a smaller bottle than 40ml. I am only using just over half before the 28 days is up (I know I have a few days grace, but its still a lot of waste). My couple of questions are: 1. Does Caninsulin, in the UK, come in smaller bottle size? 2. If so, where can I get these from, preferably online? Many thanks!!
