I searched over the forum, I know you must put in AA etc, the problem is, I4m not home, so the package will stay in post office, NOT in fridge, and IGF in powder form..How long can it stay this way..? one week?
I know in fridge it's 1-2 years, and outside the same if diluted with AA..
My question is very specific, IGF POWDER, outside..

Thanks.
