I have a question about HCG. I know that it can be kept for a very long time while the two compounds are unmixed (the powder and the liquid) and I also know that you must refridgerate it once you mix the two. My question is how lond will it last while mixed in the fridge? I have a 10,000 IU bottle and don't plan on using it all on this cycle, would it be able to last to my next?
