Im not a huge believer in expiration dates within reason. Yes, of coarse if something is like 3 years expired I may think twice(dairy not included) . However 2 carts of my FINA expired January 2004 and I just recieved 2 more carts that expire like 5 months from now. There is a noticable difference in colour between the two. the expired ones are a very light Yellow, whilst the newer ones are darker. Im still going to use the expired stuff. I mean they expired 2 weeks ago. Does anyone think there will be a huge difference in strength?
