You original question was what is the best single compound, oral or injectable, to use for a cutting cycle. Test-e has a long ester attached to it, and will also cause more of an estrogen rebound than say TNE (test no ester) or prop for that matter.
And being 5'11" 180LBs, 15% BF means that you have 27LBs of fat. If you was to drop 15LBs of that, you would be sitting at 165LBs, 5'11", not a real big guy. You know that you cant turn fat cells into muscle cells, so you have around 10LBs of excess stored energy to utilize. Using test-e will be fine as long as your diet is formulated and taylored to doing a cutter cycle, but again, no ester test, or even prop, is your best bet for a single compound cycle for cutting. But if I was you, I would go with a long estered test like enanthate and eat real clean, caloric intake for you should be around 3000 cals aday. If you need to know how to break it down as to what to eat for whatever your goals are, check out the diet forum.
