Eitehr test e or cyp would be a good option. They are almost the same. In the real world, you will not see a difference between the two. At your age, you might qualify for HRT. It would not hurt to get your labs done before you start. This way you will know what your best natural production looks. If your test is low, you will feel better in your nromal day to day life, using a TRT dose of test.
For a cycle, Here is how I would set it up
Test E or Cpy 500mg EW
adex .5mg EOD or more if needed
PCT would start 2 wk after last shot or you would then start your HRT
