I do agree with @a_ahmedto an extent he is a knowledgeable member. But I don’t agree with taking an AI unnecessarily. Crashing your estrogen is just as bad as high estrogen. Buy the ai and keep it on hand and monitor for high estrogen symptoms and only take it if it presents. With your body fat and 300mg you shouldn’t need it. And it also hasn’t been said. Do bloodwork before you start and again mid cycle and at the end of cycle. You need to know what’s happening in your body. It’s what keeps you safe and healthy when doing this.
