I read HCG once mixed is good for 5 days even in the fridge (and probably is), all HCG seem to come in 5000iu ampoules. I was thinking, if I was to break the ampoule and get the block of powder out, would I be able to split it into say 5 equal portions? The I would able to mix as much IUs as I need every week. Has anyone tried that? Or will the powder just scatter? It seems like a solid block rather than dust.
