Just found a tub of MP Bedtime Extreme at the back of the cupboard that must be a year old; it's got best before handwritten on it of 06/2008, but I'm wondering if that's only if it was unsealed?

Looks and smells alright...

the protein degrades, so the protein content at the start will be higher than at the finish.

How does it degrade?

I know the count will be lower but i know thats due to it absorbing moisture through the air

Cheers guys! I've used some of it and seems fine...although wouldn't say it tastes good as I've remembered that why I stopped using it in the first place!
