I cannot answer your heart related questions. But about when you can see a difference will vary from person to person. I felt that my skin became softer and smoother the first week, and felt pain beneath my nipples after about 1 months. However, I will advice to be careful when you are self medicating. Especially with Androcur, since it can be very aggressive against your liver at higher doses. I don't know if you could go to vårdcentralen and request a hormonal check up, but also other values that has to be considered when taking the blood samples.
