Hmm well Fehu (Growth) kenaz (harnessing energies related to sexual, pituitary gland would seem to be related) Jera (change) Sowilo (action) could be raised to increase growth etc...
I would more importantly work on the chakras related to pituitary. Iirc that would be the throat or 5th chakra.
I personally would do the energy circulation like right before climaxing and create a ball with that energy and circulate it through your chakras. I would program that ball with your 6th chakra for what you desire. And then place it in your 5th chakra or directly on your pituitary gland if you can feel it. Sorta like working the philosopher's stone.
