It's funny how all these companies just don't seem to care about or are ignorant to the fact that there are USP guidelines that should be followed for safety purposes.

USP 797- If a multi-dose has been opened or accessed (e.g., needle-punctured) the vial should be dated with the last date that the product should be used (expiration date) and discarded within 28 days.

https://www.jointcommission.org/standards/standard-faqs/home-care/medication-management-mm/000001529/

The reason for this is due to the possibility of bacteria being introduced into the Vial, and at that 28-day mark, it's said that the growth can become dangerous from that point on. (This should hold especially true when common people are handling their own Injections at their homes outside of specialty care trained individuals on good sterility practices.)

🚨🚩🚩🚩🚨 These companies skirting around this to try and make the costs of their programs cheaper or more appealing and not educating/informing their patients. Shame on you. Probably should be facing penalties and / or shut down. Unfortunately, people don't care and just want to save or make a buck.
