Ive heard mixed things regarding this. When i ring the drug manufacturer, they say it must be used within 24hrs once mixed or they cant guarantee it will be as potent as it should be.
Others here say it can be stored for up to a month once mixed.
The other day i heard that you should mix with bacteriostatic solution instead of just the normal sterile water they give you in the box.
Ive been just mixing them into needles and injecting them as needed with the normal sterile solution. They dont stay in the fridge for longer than 2 weeks. Is this ok or do i need to worry about them going "off".
