i was already diagnosed with PCOS before starting testosterone and since i suck at taking anything in pill form, opted for depo-provera shots... which had completely stopped my periods before i started T. After reading all of your post i think im gonna get one more depo shot just in case to prevent my period from coming at all while on T. The shot last 3 months so by that time i can keep my periods away with T alone. My gyno said i can take both T and Depo at the same time. It is definitely a good way to get rid of periods pre T but it can take 6 months to 1 year to fully stop your periods.
