Im assuming you are talking about B-alanine and not alamine, but honestly i do not think you need both of em. Imo creatine is enough since they basically do the same thing - longer, harder and more reps, but different mechanisms. So it is more of a do you want to question rather than should. Personally id go for just creatine, the beta sorta hinders the burn for me and I prefer feeling the burn #Bigdickenergy. But then again they might work slightly different for you so maybe just test both out, see what you prefer. Usually the best way of finding out stuff like this is to try.
