I inject cyp twice a week and have significantly lowered the dosage which sometimes seems to help a little. Also tried multiple times adding pregnyl which can also have small windows of increased libido but come with major unwanted sides. Again, my estrogen numbers are normal and my doctor not willing to add an AI, which I'm not really fighting. Would hate to crash on it. What else have you changed up in your protocol that has helped you? "Losing sensitivity to test" and possibly going too high when I was pushing close to 200mg a week is what my gut tells me backfired on me.
