Lot of clinics and docs would consult with you and likely would get you on TRT if you’ll pay out of pocket for it. The only thing is whether it would benefit you more than libido. It can be a very strenuous process so I wouldn’t jump on it unless it solves more than one symptom.
Like @systemlord and I have suggested, just try isolating diet, your workouts and any supplements you may currently be taking. Do one thing for a month straight and reassess. Then, consult with a doc about exploring medications like TRT.
Honestly sounds like you’re just trying to find a shortcut. If you’re not willing to do what we mentioned naturally, good chance you’ll be perpetually fucked when going on TRT.
