Hey guys...I have a bottle of clen that I am going to aid in my fat loss with a good diet and cardio...quick question..the bottle I have is a bit old. Is the clen still good, less than a year? Does it go bad?? It looks a little bit darker from when I had it..or should I just be safe and order another. I didnt use the rest of the bottle because I went out of the country and got off my workout....please advise. Thanks!
