Why would androsterone cause sensitive nipples ? This makes no sense ... I was using androsterone for a few weeks and was getting sensitive nipples but didnt think it was androsterone stopped for a few weeks no sensitive nipples .. used 2 drops today and sensitive nipples are back .. I also get the same with 11 keto dht ... Are they increasing estrogen or prolactin? Or is there something else in these products?? I've also never had sensitive nipples untill using these so it is definitely androsterone and 11 keto dht..
