Pregnenolone is also synthesized in the brain and central nervous system, where it acts (directly and as the sulfate) as a neurosteroid.   As a neurosteroid it serves a variety of functions – most notably as an enhancer of NMDA activity and suppressor of GABA activity.  This may in part be responsible for its purported memory enhancement, mood elevating, and energizing activities. 

Pr Spray provides pregnenolone in a sustained release form for maximum round the clock bioactivity.
