I was using Ovidac HCG and that was powder form that I reconstituted on my own. I just ordered some Hucog to try out, thinking it was powder as well. Guess I should have looked a bit more into it, because it is reconstituted already...or maybe I should say "pre-mixed". The box says to store it at 2-8*C and I have no idea how it was stored before it was shipped to me. I do know that powder form HCG can't be left out of the fridge, so I don't know how this stuff can be out of the fridge and shipped internationally and still be OK. Anyone have experience with this?
