My first cycle, 2 years ago (I'm currently 52), was Test E only. My dosage was 500mg/week and I REALLY "felt" it "kick in" at about week 4. By stating that I felt it, I mean that my libido jumped into high gear, I was feeling great, energy was through the roof. The muscle mass (20lbs) and strength gains became apparent beginning about week 6 for me. I agree with the others that you may have an underdosed batch. What is your diet like if I may ask?
