Not sure how relevant this all is, but I had heard nolva can be hard on the liver.
Found these on pubmed. Hopefully someone with a bio background can add further light.

Adjuvant tamoxifen has become the treatment of choice against estrogen receptor-positive breast cancer. Adverse effects are rarely observed and since symptoms of hepatic steatosis, non-alcoholic steatohepatitis and cirrhosis are usually negligible, such effects are not well characterized despite large cohort studies of adjuvant tamoxifen. This issue remains to be systematically studied. The present study consisted of 136 breast cancer patients treated with or without tamoxifen. Patients had laboratory tests once each month and underwent abdominal computed tomography (CT) annually for 5 years. The extent of hepatic steatosis was assessed by CT as the liver/spleen ratio. While receiving adjuvant tamoxifen, 40 of 105 patients developed hepatic steatosis (liver/spleen ratio <0.9) without obvious changes in body mass index. Twenty-one had a liver spleen ratio of <0.5, whereas none of the 31 patients treated without tamoxifen had a ratio <0.9 or <0.5 (p<0.0001 and p<0.0001, respectively). Hepatic steatosis was recognized in 35 of the 40 patients within the first 2 years of receiving adjuvant tamoxifen and 21 of the 40 had increased transaminase levels. Liver biopsy revealed NASH in 6 of 7 patients among the 21 with a liver/spleen ratio of <0.5. A subset of individuals given adjuvant tamoxifen developed progressive hepatic steatosis without significant changes in the body mass index. We suggest a liver/spleen ratio of <0.5 as a criterion upon which liver biopsy should be recommended since NASH frequently occurred in such patients.

One-third of the breast cancer patients who underwent tamoxifen intake showed less than 0.9 of their liver/spleen CT (computed tomography) ratio on their annual CT study, and were diagnosed as having fatty liver (hepatic steatosis). Among them, patients who showed a lower liver/spleen CT ratio of less than 0.5 were recommended to undergo needle biopsy of the liver in order to obtain histopathological confirmation of non-alcoholic steatohepatitis (NASH), with 15 patients undergoing needle biopsy of the liver. As a result, 14 out of the 15 patients were diagnosed as having NASH, and these patients were additionally administered bezafibrate in order to prevent possible progressive changes of NASH into liver cirrhosis. In this study, we show the changes of follow-up CT findings of 6 patients with histopathologically-proven NASH who continued to undergo bezafibrate intake after the diagnosis of NASH. Two patients showed almost complete improvement as indicated by the liver/spleen CT ratio several months after completion of a tamoxifen intake of 5 years, and another 3 showed partial improvement on their liver/spleen CT ratio by bezafibrate intake in spite of continuing tamoxifen intake. Another patient with diabetes mellitus (type II) showed a continually decreasing liver/spleen CT ratio during adjuvant tamoxifen in spite of bezafibrate intake. Therefore, we concluded that the progression of NASH could be prevented by bezafibrate without any interruption of adjuvant tamoxifen treatment. For patients with diabetes mellitus, critical follow-up using CT study and laboratory tests is considered essential.
