The answer is that it really just depends. Check out ICH guidelines, but basically we do 40C for 6 months, room temperature for 2 years and freeze thaw for 6 weeks. If we run into issues with the 40C and we're pressed to get a product out without waiting on the room temperature then we'll run 30C and run that out. Like Perry mentioned you could do 45C instead of 40, it all depends. Some systems might crash at 45 that would be perfectly okay at 40 and the same goes for 30. Different accelerated tests will give you different time tables for shelf life. When I was doing innovation we did 50C, 4C and RT.
