Hucog adds something to the reconstituted product to increase shelf life. For how long I'm not sure, the info is out there. But one thing I will say is that when I ordered my entire cycle at once. This shipped the day after payment all by itself. The rest of my cycle is still processing. Depending on your source, if your is like mine which I think we have the same one. They expedite shipping. Did it come in an insulated package?
I also remember reading that this HCG is okay to store at room temp. Hucog has a plethora of info about it out there.
