My wizard went the opposite direction. She acquired a Potion of Heal, and mixed it with a Philosopher’s Stone. My DM ruled that would make a Potion of Eternal Youth. She was eternally 17 years 10 months old. Was absolutely great because frequently people vastly underestimated her. She was also an 18th level wizard/dweomersmith by the time she drank the potion.
