Its a whisk, the shakers they give you are 12oz but they recommend between 12-16oz. I bought a 16oz bottle and it is way better, if im using the old shaker cup i just slam 4oz right away and add more water
The bad flavours really do suck... I bought grape and green apple which i deeply regret. Blue ice is freaking AMAZING and watermelon is pretty fucking good too, wouldnt really recommend tropical rain either those are the only 5 ive tried so far.
all these kids paying $40 for a container of sugar substitute (worse than sugar for your body) and caffeine (simple heart problems) and god knows what else cheap chemical flavoring.
It's all a lie, there is no benefits to drinking a cup of aids every day. And they even make you mix it xD
