How stable is L-Glutamine - did I buy expired one?

[Alkaline]

I read somewhere that when glutamine powder becomes lumpy, it have reacted with water from the air and have turned to something else. I bought a new jar like that. Exp date in 2007. Did I just waste $70?

I am very new to the supplements. So advice will be much appreciated.
