yes correct, also depends on the carrier, if it sits for a while in PEG or PG it will need to stay cool and hsaken every once in a while.
PEG and PG will break down with heat and in a sealed container, its a bad thing.
so maybe cool and sealed unopened in pG or peg or even solvent at least 50 proof.. about 2-3 years.
tabs if not gelatin caps maybe longer or less if gelatin caps. they corrode with moisture remember.
I had some from 2 years ago do that when i opened the bag they were all stuck together..kinda sucked lasted almost 2 years though.
