Your 19 years old so you're at the prime of your Test production. Your body should be producing about 46mg of Test per week. If your Test production has shut down you're getting back to normal at 50mg/wk injection. What does it mean to be in the normal range? The normal range is huge. You should be at the top 1/3 of your age range to be feeling good. Just go 50mg/wk and see how you feel.
