I am with PAIN on this one. If you are over 40 you are just not going to be satisfied with the way that you feel with your natural level of test. I have been all over the place and have settled on 200mg/week TestE. it keeps my values at between 1100 and 1200 and I dont have to take an estrogen blocker with that dose, and my hemoglobin stays between 16.5 and 17.0
