about 4 months ago i bought some Controlled Lab's White Flood Nitric Oxide. I only used it about 3 times. I went to use it today for the first time since then and the powder was hardened, and in some spots it was darker then others. nowhere on the container does it say anything about keeping it away from certain temperatures or anything. it was in room temperature anyway. do you guys think it's alright to use it if i crush it up, or no? like i said, in some places it was discolored. i don't know if it's mold or what. or should i just stay away from nitric oxide anyway? i know now that it's not worth the money, but i already bought it so i figured i might as well use it up and see how i respond to it.
