Hi.
I have a question.. I have some Human Grade HGH Norditropin SimpleXx 10 mg/1,5 ml cartridges. It comes already mixed and according to manufacturer it can be stored in the fridge 2–8 ºC/
36–46 ºF or at room temperature Up to 25ºC/77 ºF 3 weeks. All cartridges has expiration date 3/2013. My question is how long after this date the substance lasts? Of course it has been in the fridge from the beginning and still is. How long after expiration date is it safe to use? Or should I avoid using it after the date at all just to be sure? Thanks.
