It will work. It just won't last long term, the way AA will work. I would expect to see it start to break down after a few wks. Maybe less. I've gotten a little behind on the QA, having just started Project Get Shredded, here at Naps, so I am sorry, to you and to everyone else, that I have not had as much time to answer questions as quickly as I'd like. I think I have a fix though. Now keep in mind, this isn't something I have done, but you might want to give this a try...
Ok, so if you ever decide that you want to stop using IGF, you can always throw a mixed vial into the frezer. This will arrest the break down until it thaws. So what if you were to preload your insulin pins with the dose you want to use. Then put them in the frezer. You might need to leave a little air in the barrel while it freezes, so the water can expant when it freezes. Then take a dhot out of the freezer several hours before you plan to use it, giving it a chance to thaw.
Its hard to tell if the IGF is working or not, I usually get a better pump from IGF, but I keep the dose pretty low, so the difference for me isn't huge.
