from http://en.wikipedia.org/wiki/Pregnenolone, they state
Pregnenolone, 3beta-Hydroxypregn-5-en-20-one is an endogenous steroid hormone involved in the steroidogenesis of progestogens, mineralocorticoids, glucocorticoids, androgens, and estrogens, as well as the neuroactive steroids. As such it is a prohormone, though it also has biological effects of its own, behaving namely as a neuroactive steroid in its own right with potent anxiolytic effects.
Me: anxiolytic – reduce anxiety
This stuff, along with DHEA can be used in low doses to restore cortisol balance in the body over a year. This is espoused by “The Kalish Method”. His book is on order, and we’ll see what he has to say.
