It’s very complicated, but the basic process is to genetically engineer a bacteria to contain a specific part of the human genome that codes for the production of insulin. Then you grow a big batch of the bacteria and feed them so they produce insulin. Then you chop them up and separate out all the stuff that’s not insulin.
Each of those steps is very complicated and protected by many patented processes and machines. That’s how there can be so many different providers and different cost profiles.
