Some endos in the VA do offer the three month shot if that's what you are referring to. It was offered to me, but after much research, I opted for micronized Progesterone instead, just to see how I would react to the new medication. I opted for better mental health, rather than taking the chances of severe depression. I already have severe PTSD with depression. Although while on the Progesterone, my moods are much better, and my depression much better, I prefer to cycle my doses, rather than a steady dose. I do this not to mimic a cisgender woman's cycle, but because I do not want my body to get used to the progesterone, and for a much better effect as in a woman's cycle. Cisgender women, only produce Progesterone the week of their cycle, and the week following their cycle. That being said; optimal development of breasts would I occur through cycling.
