Ok so please lmk if I've missed anything you asked! First off your BC containing not only estradiol but a progestin means you actually may not have estrogen dominance(potentially) as progestin is a progesterone though synthetic so not the best for you and doesn't work as well as bio identical progesterone. With cupping they would be meaning vacuum systems like noogleberry or Kangzhu! Both of which you can buy online, you buy a size based off your current measurements of your bust, you place the vacuum cup over your entire breasts and "pump" to create a vacuum, over time this leads to increased tissue though I have seen some people get stretch marks and saggier from this due to the tension. The progesterone cream I personally think looks the most promising is biolabs progesterone cream I'll attach a link

There are a few different strengths on the website so it totally depends upon what your needs are.
MSM alone definitely CAN give results in some people as has been shown a good amount of times here and if paired with massage even better! I wanted to say aswell from what I've looked up please don't use ricin oil it's from the plant that produces Castor oil but from a different part of the plant and is apparently toxic in a few ways, use an oil like sweet almond oil, sunflower oil, actual castor oil, fractionated coconut oil etc and you want the oil to say pure and unscented, preferably unrefined aswell, I personally use NOW solutions sweet almond oil with also Sunflower oil as a half half ratio in my oil.
