Agreed, always cycle PC. It's best to use it for two weeks, then off for two weeks. Every two to three days, you should apply it to other parts of the body than the breasts, to absorb it better (apply on places where the skin is thin and veins are visible, like the wrists and inside of the elbows). Do that for two to three days, then apply on the breasts again. This will keep the receptors in the breast from filling up, which would prevent your body from using the progesterone. Also, the best part of the breast to apply it is going to be the very top of the breast, like the top of the pectoral muscles. Although, if your breasts are veiny, applying it directly to the full breast may work just as well.
