I purchased some Mast approx. 8 months ago, Its been stored at room temp. in my nightstand drawr and has not been tampared with what so ever. I recently went to take a look at it and found some stringy looking things floating around in it. Could it be that it has expired before the date of expiration? Is that even possible? I asked the person i bought it off of and he told me that i had to heat over boiling water to get rid of it and prepare it for use. Please somebody help me!
