Hi,
I buy my HCG from the chemist in 500iu amps. I have asked my chemist if he keeps it in the fridge to which he replied YES. I am not so sure though as sometimes my balls feel full and great and other times they feel smaller.

What are some symptoms to look for to tell if HCG is working ?

Getting HCG in 500iu Amps (box comes with 6amps. 3 hcg and 3 solution) would the chemist need to put it in the fridge as soon as he gets it in ?
