I have a 64oz container of BFWD that has never been opened. I know that it is at least 5 years old. Is it any good? How long does unopened product as this normally last.
I have one that is older than 5 years old. Never had an issue. I frequently shake the bottle to mix everything back up. It does have a tendency to separate if left sitting.
Check for mold, and then shake it like you've never done anything! Like shake until your arm falls off, should be fine though. These products should last years if kept at proper temps and such.
