Alpha-GPC is a Choline-containing supplement that is a popular compound amongst muscle building supplements because human growth hormone secretion is amplified with administration of Alpha-GPC in response to stimulation via GHRH [1]. One study using Alpha-GPC has found increased attention and reaction time in persons undergoing acute stress [2]. Therefore it is additionally assumed to be a nootropic with cognitive enhancing effects. Since Alpha-GPC is naturally found only in red meat and organ tissue, Alpha-GPC supplement are generally a good alternative for vegans and vegetarians. 

Often used as a highly efficient choline supplement, Alpha-GPC is commonly taken in addition to racetam supplements such as noopept.

Alpha-GPC 50% powder is more usable than the 99% version as it is less hygroscopic (i.e. it absorbs less water from the air).
