Yeah dude, your test levels are still peaking, don't mess with your hormones for many more years, and even then you need to be careful. I feel your pain though man, about your fat trimming issue. Just keep doing more of the same, running, training, lifting.
One thing I did recently and it REALLY did work, I pretty much fasted, drank only liquids for about 2 days, drank 2 myoplex deluxe's a day for protein and nourishment, and ran once to twice a day on top of training. I literally watched the fat melt off in just 2 days. You will get crazy hungry though, you just need to use that iron will and resist. When you do finally come off the fast you will have an urge to binge eat. Don't. Your stomach will have shrunk a little and you will need to get used to food. Control your diet, resist the cravings, and you'll be on the track to the lean you seek. Be well.
