I can’t find any real clinical research since it hasn’t been used to treat breast cancer in nearly 5 decades. However, I’ve heard Dr. Thomas O’Connell discuss Masteron’s negative effects on lipids in one of his harm reduction videos. I know that Masteron will have a greater effect on lipids than testosterone given its strong anti-estrogenic properties. But I really have no clue if it’s as drastic of a reduction as is seen with Oxandrolone. I would take an educated guess and say that it probably wouldn’t reduce HDL by 40% (in low doses) like Oxandrolone would given that Oxandrolone’s effects on lipids are mediated through its direct effect on the liver.
That’s weird tho, I thought Oxandrolone was the least hepatotoxic oral as far as AAS’s go.
