Trt advising please..

Hi, I’m on 150 mg of TRT and have been trying different protocols. What I’m doing right now is pinning 4x per week. My libido has been shot for a while, and I’m guessing it’s due to my DHT. It’s at 1.6 nmol/L, with total testosterone at 33 nmol/L, free testosterone at 0.989 nmol/L, and estradiol at 134 pmol/L.
My lab range for DHT is 1.4–4.0 nmol/L.
I’m not sure if I’m deficient in any vitamins or what the issue could be, but I have no morning wood, I’m tired, etc.
Any advice on what I should do would be great. Are there any alternatives or ways to increase DHT? I’ve tried Mast/Proviron with no effect. Even 20 mg of Cialis barely works.

Also wasn’t born with any issues with hormones started at 17 something went wrong idk thanks
