ABB Gluta-Force?

Anyone ever tried this glutamine before? I’ve had probably 20 different brands and all were tastless and odorless but this shit tastes and smells almost rotten. Just wondering if I recieved a bad batch. Probably should’ve asked before I went through half the tub.

I sell ABB in my gym and use this brand my self. It sounds like yours is messed up! Do you happen to keep it close to anything that it could absorb like baking soda does in the frig? That could be it or if it got moist it my smell but if that were the case it would be clumpy not a fine powder.
