I would second what Ramo said- if I were you, I’d eat a high volume of clean food and lift like a beast. You ARE a beast. You can become an even BIGGER beast. Literally, the sky’s the limit for people with genes like yours.
However, it seems you want to do wrestling in a middleweight class, which means you’ll be walking around at 200 instead of 250. I respect that, even if I cry a little on the inside for the loss of your potential.
As far as supps go, Biotest creatine is excellent. Follow the loading pattern (10g, 4x/day for 4 days, followed by 5g/day daily thereafter). For best results, take it with your Biotest Surge. The insulin spike from Surge helps shuttle the creatine into the muscle cells where it does the most good.
BCAA’s are like ultra-quality protein. They’re good, if pricey. As far as supps go, they’re mid-way down on my list. I do not currently use them, and do not recommend them for a cutting cycle.
Instead of BCAA’s (or Surge, but that’s just my take), I would recommend getting Flameout. Fish oil has more benefits than a job with Homeland Security, and assists in the fat-loss process (and bulking too, but that’s another story).
DO NOT take HOT-ROX (HOT-ROX is Biotest’s fat-burner) until you’ve managed to lose fat successfully for at least a month. It’s important to know you can do it on your own without exogenous help, if for nothing else to guage the effectiveness of said help.
DO NOT attempt to guage your bodyfat levels with anything less than a professional with calipers. There is the possibility that you will gain muscle and lose fat at the same time in equal amounts, thereby making it seem as if you’re doing nothing because the scale is standing still. Instead, measure your fat-loss progress by recording with a tape measure the circumference about your hips (belly-button lattitude). IME, this is much more reliable.
Lastly, as far as training and diet go, I recommend these:
Training: The Waterbury Summer Project

Diet: T-dawg Diet 2.0

WSP only lasts for 8 weeks, so you may have to do it two or three times. In eight weeks following it and a strict diet, I lost 18 lbs. While my strength levels did drop, they came back within four weeks, and actually exceeded my previous levels, so don’t let that scare you off (too much).
There is such a thing as metabolic down-shifting, where your body gets used to operating at a lower caloric level and stops burning fat as much as it used to. It is therefore necessary to either a) increase your activity levels or b) decrease your caloric intake roughly every 8 weeks in order to keep fat being burned at the same rate. If you follow WSP (Waterbury Summer Project, the training program listed above) increasing your activity isn’t really an option. Therefore, plan on decreasing your calories over the course of a cut, and don’t go balls-to-the-wall in the very beginning.
Good luck. I sincerely wish you success in your endeavors. Do not be afraid to ask further questions, and post with updates of your success.
