I was looking for choline supplements to support routine liver detoxing when Google took me to this site. I bought Coluracetam, Lemon Balm, Alpha GPC and Centrophenoxine. I do system designs with long hours of intense concentration and have been experiencing classical Thyroid and menopausal brain fog. At the time I was also going through a prolonged and very intensely traumatic experience. I cannot say that I experienced any specific sensory enhancement experiences or even any immediate detectable effects but, after about a week I suddenly realised that my mind was sharp and clear, my thinking processes were flowing smoothly, the mind fog was gone, but the most impressive benefit was that I was no longer in that deep dark pit of hopelessness caused by multiple traumas. It was one of the most pleasant surprises ever, because I was entirely focused on improved liver detoxing. The tiny dosages will make the stack last for several months. After these amazing benefits I shared the stack with a relative in a very stressful job to enjoy the same benefits. I can recommend this acetylcholine supportive stack without any reservations.
