Overview
Pregnenolone is a precursor to several key hormones and neurosteroids involved in brain function. It has been explored for its potential effects on mood, memory, and stress resilience. However, because it influences hormonal pathways, its use requires caution and an understanding of individual variability. Effects are not consistent across all users.
