blood bloods libido

Hey I take 100mg a week, 50mg e3.5d of Test E. Been on this dose for a year. Is there any way I can improve libido through my protocol? Or do I need to be trying other things? Here are my blood results, taken right before next shot: Test 24.9 (10-35) Free T 621 (225-725) SHBG 27 (13-71)...
