They exist (most insulin produced today is rDNA biologics), and are about $25 at Walmart. Of course, the same thing at CVS or Walgreens is $100+. I know b/c I switched back to using them after needing to travel internationally for more than 1 month at a time... my expenses went from $2500+/mo to under $200/mo, including the extra testing supplies required to support this regiment. At the same time, I take up to 7 shots a day and am definitely now a "Medical Tourist". Yes, I can go to Europe or Canada and buy supplies (at retail cost) for less than the US, including travel. But - that's actually MORE FREEDOM for me. YMMV.
