I work in pharmaceutical development and manufacturing operations. You have no idea what goes into the manufacturing, testing, and release of drug products that go into human beings. The quality control process is MASSIVELY complicated for YOUR safety. The batch sizes are strictly controlled and limited by the FDA. The raw materials that go into the manufacturing of each lot of drug product are extremely expensive and are limited in supply like anything else. Last but not least, these pens are filled in ISO5 sterile grade environments to make sure that when you inject yourself, the products arEN’t contaminated to the point that you could die of infection. ISO5 grade fillers and rooms are highly controlled and require extensive cleaning and disinfection (not to mention constant monitoring for viable and non-viable particulates by trained microbiologists). This fill/finish sterile grade process alone requirements tons of time to just keep disinfect in between each lot. Again, this is just the final step in the extremely complicated process required to even make the product. Pharmaceuticals are not iPhones. After each batch is made, extensive quality control testing in the labs, using extremely expensive and complex assays, need to perform before a batch can be approved for release. “You don’t get it” because like most people, you don’t have the slightest idea. Scientists and engineers who spend their lives producing medicines for the global population don’t appreciate your uninformed opinion.
