Fantastic Stack: CILTEP® + Acetylcholine Brain Food
I've been using CILTEP for some time now and it is a high-quality product for concentration and mood -- just to name a few of its benefits. However, combining it with Acetylcholine Brain Food pairs nicely with CILTEP by amplifying its benefits. I'd highly recommend this particular stack. You may have a different experience with this stack but for me, it works well. I'm very pleased with the results.
