Once you mix it up, how long can it be safely stored in the fridge ?
We're talking 5000iu's
1 month...
There probably is no way you're going to use that much in a month period. It's a catch 22 with 5000iu of HCG...
You'll probably need to run 500iu/week, thus wasting 3000 iu....

I, however, have access to 2000iu amps of HG HCG, pretty cheap too.
