Alpha Brain is a similar stack to some degree but includes Alpha GPC instead of CDP Choline. It also has more ingredients. Generally I prefer to keep stacks to a bare minimum. Also if I'm going to take a Choline source I prefer CDP Choline over Alpha GPC. And yes, these stacks are expensive indeed. With the 72 hour half life of CDP Choline you can get away with a lot less frequency as one dose lasts a long time. It's like a 1 - 2 times a week stack.
