Bio Gender

Despite being a lab rat most of his adult life, Dr. Rice isn't a flighty academic. Once she accepts her new posture as a female, Paula, as she now calls herself, seeks someone who would help her market her invension not as a Gender changer but as a 'fountain of youth' kind of serum that wealthy people would pay dearly to acquire.
She find this candidate in the person of Justine, an aging business savvy attorney who is also a transdgender woman. Paula proves the viability of her formula by injecting Justine with it and turning her into a strapping young man.
The two of them market the formula mostly to wealthy aging Hollywood divas intent of making a comeback, and make millions of dollars.
