but we are yet to get there and if I did I wouldn’t bodybuild again and keep my hormone levels low testosterone may not increase cancer cells to multiply but I wouldn’t be healthy enough and certainly wouldn’t risk my health at 45 as the age of humans living life is around 70-80 years old depending on genetics lifestyle
nobody is going to give you advice so you are better staying of bodybuilding boards and just do what a doctor says or go buy them and self prescribe yourself with whatever knowledge you have.

Good luck wish you good health for the future and long healthy life from now
