Humulin Potency

[DIEZEL666]

Does Humulin get weaker as it approaches its exp date? I have a bottle that expires in June of 2005 and I have been taking 10 iu's pre workout. It doesn't feel like anything is happening. ANy help would be appreciated.

I am having the exact same thing happen to me! Except that I'm about 3 months past my expiration date... The bioavailablity of it definitely degrades especially if it's had temp change a couple of times. I just kept adding an IU until I felt it again. I have to stop and buy some new stuff, it's so cheap no sense in using old stuff.
