AGP Choline (aka Alpha-GPC) is arguably the most clinically studied of all nootropics. Available only as a prescription until the late ’90s, AGP increases the amount of acetylcholine, and plays a supportive role in attention, concentration, memory formation and recall. It is naturally found in breast milk, meats and small fish, and Synaptic uses a vegan form derived from non-GMO soy.

By weight, A-glyceryl Phosphoryl Choline is the most efficient form of choline nootropic on the market. It’s also the most expensive. We use 333mg of 99% pure AGP choline in every 2ml serving.
