Actually it will depend. They have a shelf life for a reason.
If is just over a year old then it -should- be just fine. If you got it a year ago and it was on the shelf before that the who knows how old it is. If it's still has the original seal I would expect it's good.
My local supplier sell the oldest stock first and they date it when they get it. Some shelf lives are shorter than others. You may not be able to tell for sure till you catalyze it too.
