Well, what are you expecting out of it? In my experience creatine is great for muscle recovery, and getting glutamine if it's in your creatine. I never gained any mass off of it but like I said, It was great for muslce recovery.
Agreed Creatine is great for recovery as is Whey protein!!
creatine is in not for mass/muscle size,creaine monohydrate is an energy/recovery supplement,it has worked wonders for me(i am a bodybuilder if your wondering)
but as someone else said already it does not work for everyone,give it a try for a solid 4-6 weeks no noticibale difference?? then forget about it.
