Be careful bud. My wife got a voice drop that is permanent. Fortunately, her voice was already squeaky high so the drop is just a little lower than a typical woman's voice. That said, her voice is still cracky and I hope that she can figure out how to not make her voice cracky in the future.
Women actually do need a PCT it's just not anything like ours. If she continues to do gear and especially in her off-season bulking efforts, you'll notice that her fat distribution starts to look like a man's, which tends to gravitate to the center of mass and away from the breasts. Trust me, you don't want that look for her. Because of this, I recommend equal amounts of time off to let her body become estrogen-dominant again. It's amazing to watch, too. If she keeps her diet clean and still does some cardio (or whatever to keep lean), you'll see the fat leave her stomach, arms and back and literally pile up in her breasts and butt, with no significant change in weight or total BF %. That's how those women that you see on IG do it that are built like a brick house but still have a perfect figure top to bottom. It's an art.
Progesterone cream as well as a number of supplements/herbs that increase the breast growth and estrogen receptor sensitivity to the breast and butt regions will be necessary for her to get her female figure back. Truth is, I'm pulling the plug on my wife taking androgens from here on out. Her work ethic is enough to get her where she wants to go anyways. From now on, it's IGF and insulin for her (and myself).
