Should I add Animal Stak to my work out supplements?

Currently I am on GH Stack from Universal Nutrition, NO-Xplod (caffeine free), ON Whey Protein. I am thinking about adding Universal Nutrition Animal Stack to this list. I have mono hydrate creatine also but I haven't been taking it. My question is would it be a waste of money to add the Animal Stack or a good idea. As a side note I'm 25 yrs old 6' and 183lbs.
