First of all, liftmode carries a variety of quality products as I have ordered many different things from them and they all seem to work effectively. The same can be said for their L-Theanine. I usually have some form of caffeine when I take the L-Theanine and I can definitely say that the product helps smooth out the jitteriness caused by the caffeine. When taken without caffeine I feel a slight relaxation that helps keep me stable in a sense. The effects it has on my anxiety is effective as I said before it keeps me stable. All in all, Liftmode carries effective batches of L-Theanine.
