You need to read up a lot on the endocrine system.
Positive effects? All things that steroids provide
Negative effects? Endocrine shut down and potential negative impact on cholesterol/blood pressure. Wouldn't worry much about liver at that dose if duration is reasonable but even then I know doctors running 50mg a day year around
Okay. I should have mentioned that I'm a male, 155 lb. I know and a bar is supposed to be pretty safe for females to take and that it's one of the easier ones on your liver.
