I didn’t have ins for the longest time and I got most of my insulin from my Endocrinologist in way of free samples, then I was informed by the nurse practitioner that at either Walmart or Sams Club you can buy an insulin called Novolin(I use Novolin 70/30 mix) they have the mix and the regular. They are only $24.88 per vial, which is extremely cheap and you don’t need a script. It’s basically like a non “designer” type insulin, and my glucose numbers are perfect. I used that for over a year before I was put on disability and Medicare, now that I have ins I have my doctor write the script for the same insulin( Novolin) as opposed to Novollog or Humalog(brand names that the Dr’s try to push) but you can tell them which one you want to use. I pay as little as $74 for a 3 month supply( about 15 vials). It works like the more expensive ones, it’s cheap for people with no ins. I’ve had no problems with it!! Look into it, it’s well worth it! Best of luck!!
