Expiry date?

[gothra]

I bought my calcium and herptivite 2 years ago, there are no expiry date on the tubs; shall I replace for some new ones now? Can calcium (with D3) and herptivite expire? I still have a few of them un-openned at the moment; if they can expire, I'll probably need to throw them out.

They do expire. I think two years is around the time they do expire. But atleast the prices aren't that bad considering how long they last.
