exp date of superplasma

Ive had some super plasma for about a year now and its never been opened.... should i be concerned?

open it and use the old smell test. if it smells rancid or overly sour then dump it. it should be ok though if it's been kept i a cool, dark area.

you should be concerned that you had this great product at your disposal and have not used it for over a year. Smell test is the best way to go.
