I'd be curious to know as well...
...but if it helps any, 2 months ago, I ran a 3 wk course of HIGH QUALITY Ipa / Mod-GRF (that I received in August of 2011). To my pleasant surprise, that shit was as good (if not "better") than when I ran it in Aug of '11...
Age aside, (from Aug '11 to Feb '13), those suckers survived several power outages and a road-trip (almost a week long).
Despite the age and, at times, unstable storage temperatures, those peps performed like none other!
I have a vial of each left and will likely run the last of them very soon. I'm gonna really miss the peptide days
