Daily injections is a double edge sword, those smaller injections could mens less conversion to T->DHT which is needed for libido. I also wonder if you gave the daily injections enough of a chance, a lot of men don’t give themselves enough time to reach homeostasis.
This might be your libido problem, your E2 pre-TRT was 16 pg/mL and libido was fine and now E2 is three times this value. I think the problem you are having is you aren’t able to have the correct T/E2 ratios on TRT like you did when natural. You might do better on the T scrotal cream.
