Does protein powder go bad?

[apex]

So my powder bad tore about 6 months ago. I store it in a Tupperware container which is sealed. Anyone have any idea how long this stuff lasts? It still tastes normal...

It will start to lose potency and some taste after a while. If it was cheap and your not sure, throw it out. If you need a top quality protein, I use MAP ( Maximum Absorbed Protein ).
