before mixing powder, it is necessary to store vials in the fridge?

im confused about it...
i know that when u mix the compounds then you have to keep them in the fridge (i was thinkin about loadin 5 syringes with the 15ius vial and use them for the next 5 days and so on...)
but, before i mix it, do i have to store vials in the fridge or room temperature will be ok?
aslo, can anyone have a good link for a first timer with gh?

thanks bro's...

i assume that your talking about hgh but any how keep it in the fridge as much as possible before and after reconstituting.
