Insulin Pen for Pfizer Genotropin 5mg or 12 mg Cartridge?

Is there an insulin pen that can fit these 2 chamber cartridges?

Not that I know of. Part of the patent on those types of drugs is related to the administration device. So a Pfizer device is going to made for Pfizer drugs. Unsure if there’s a generic pen that accommodates cartridges from company x, y, or z.
