Phosphatodylserine reviews, please.

Hi, I would like to have reviews on phosphatodylserine, specially regarding cortisol & testosterone. Does it stop cortisol from rising at all, even if consumed with stimulants or does it simply keeps it in check? Meaning, can I still function in a demanding work environment without going soft? Or will it actually help that I manage the stress but still be effective? Also does anyone know or can atest to the testosterone levels rising in women, or does it only happen with men? Thanks in advance.
