I want to do a short cycle of Ostarine for joint healing. Can ostarine cause gyno and if so what should I take to counteract it? I already have gyno from puberty. The weird thing about my gyno though, is that it comes and goes during the day. My nipple fluctuate from normal to puffy throughout the day. It's only been like that the last 3 years. Before that, they were just always big. I've used a special version of Vitamin B6(forgot the name and too tired to search right now before breakfast), in order to reduce gyno and it didn't work. In fact, it might have actually made it worse. Lowering prolactin doesn't seem to help the issue. My estrogen floats around 28 normally and my prolactin last time measured was 11.4(3.0-14.7 ng/ml range).
