Source Naturals Alpha GPC -- 285 mg - 30 Capsules
noticeable mental enhancement, will buy again
I enjoy the feeling I get from alpha-GPC very much, and would recommend it to anyone. No question alpha-GPC improves mental functioning. In my opinion, it is the best choline donor for the -racetam nootropics (e.g., piracetam), which is primarily why I use this supplement (will prevent -racetam headaches). I feel more clear headed with alpha-GPC compared to CDP-choline, but CDP-choline is also an excellent choline donor. Both certain give a noticeable acetylcholine boost even by themselves, and 250-300 mg is my preferred dose. I plan to buy alpha-GPC again, but bulk powder is often cheaper.
In case anyone wants to learn more about alpha GPC, here is a link to a short audio lecture about how good alpha-GPC and PS are for your mind and body (speaker is Dr. Parris Kidd):

Very powerful. Almost acts like a stimulant. Puts your brain in high gear.
