Can someone give me a difinitive answer on IGF storage - everyone seems to say keep it in the fridge, but MR says (from gropep I think) that it's stable at room temp for more than a year or two........???
Obviously the safest option would be to refrigerate it just incase, but is it absolutely necessary??
It's a problem for me as my flatmates will start asking questions if I start leaving vials in the fridge!!
