Has anyone been using pregnenolone? Does it have lots of hormonal effects or side effects?

Unknown effects. Rises in luteal phase of the cycle along with progesterone. As far as we know, it is simply a precursor to progesterone. It has risen in popularity in hormone replacement circles that are somewhat heavy on the till for hormones. It is a "new" way, supposedly to give people higher Progesterone levels but has never been studied and no one knows the true effects. Would stay away until know more.
