Geritol

My fiancé and I have been ttc for over a year now. I have pcos, and was on a mixture of clomid, letrozole and progesterone for 5 months last year with no success. We stopped due to Covid and not being able to see the dr regularly. Anywho, a friend of my fiancé’s mentioned geritol to us and said him and his wife took it for about a month before finally getting pregnant after multiple years of trying. I’ve looked online and can find some success stories, but have also found there is no evidence proving geritol is the reason for these pregnancies. Has anyone tried it and successfully became pregnant after nothing else worked? At this point we’re willing to try anything. Any knowledge of geritol is helpful to my fiancé and I!
