That's a lot of pics to look at to see your labs! Kind of hard to go through them all. Anyhow:
You appear to have Secondary Hypogonadism. In the USA, we measure testosterone in ng/dl. You are at 271. That's about where you normally would be when you get into your 100's. Couple your low Testosterone with Low/Normal LH and FSH is how I arrived at the secondary diagnosis. More details on this are outlined in the previous link I gave you.

Your estradiol is very low too. A recent New England Journal of Medicine study outlined that men with low estradiol have a lot of health problems and they pack on the fat. Have you been gaining weight for a while? How tall are you and what do you weigh?
I wouldn't cut back your vitamin D too much. You are just a little high. Maybe try 6000 iu's per day.
Low cholesterol can impact your testosterone. You really should get a full lipid profile run. Total cholesterol doesn't tell much of the story. I'm guessing that your HDL is going to be very low.
You can probably ease up a bit on the B12 supplementation.
Were you dehydrated when you had your labs run? Your urea was high.

I think you should be talking to an endo about trying a restart or going on TRT. Don't let them put you on gels if you go the TRT route. Injections work best. But if I were you I would give a restart a try first.
