I've been having this problem with every type of protein supplement I've owned which I've purchased in 5 gallon quanities. The protein starts to go bad after about 6 weeks or so in the warm climate of Los Angeles, CA I live in. It smells different then how it did when I first purchased it, and I start to feel I may be hurting my body more so than helping it, by taking the supplements when they come to this "decaying" stage.

Now I know you are supposed to keep it in a cool dark place and have the bottle tightly shut between opening and I have been doing that.

Maybe I'm not going through my protein fast enough (one - two scoops a day).



How many scoops of protein do you take a day?
Do you currently face a similar situation where the protein starts to not smell so fresh anymore?
Anyone store there's in the refrigerator?

Ive had my large tub of Nitrean for quite a while and it hasn't changed. I do keep it under the counter in the kitchen, away from heat-generating appliances.
