Hey Milk, I actually had that same question myself when I was trying to figure out how I was gonna store my HCG, but I have read that as long as it is still in it's lyophilized form it will still maintain it's potency, even at room temperature. It is after they are reconstituted with BW that they will degrade, if not refrigerated. I actually have 2 of my own vials in their powdered form but I store them in my fridge just in case. I honestly don't believe that HCG will degrade between the time your source ships it to the time it reaches your doorstep, but that is an understandable concern.

I have 5000 iu ampules of HCG in powder form, planning to take 1500 iu e3d too during the last month of my cycle, which means that one ampule should last for apox. 9 days, but I'm a bit concerned about expiry after reconstitution, even though I plan on doing it with bs "Bacteria-Static" water.
Do you think that HCG kept in the fridge would still be good to use on the ninth day after recon.?
Thanks.
