I have an Omega J8004 juicer, and can report that Beets do work well. I don't think beets alone would do the trick for me the way Gene's stack has done, but for other guys perhaps it would be "good enough". Just from juicing a beet everyday I was suddenly getting morning wood, which I hadn't had in years.
In fact I was turned onto to TRT because of a thread I was following on one of the "Manosphere" forums. The blogger who was doing the writing was Mike Cernovich, and I'd appreciated his twitter feed as he was constantly doing battle with the Social Justice Warriors over GamerGate (As I recall he is an expert in Constitutional Law). Anyway he had contributed greatly at Rooshv's forum (Return of Kings), on a TRT thread. Once I realized TRT was going to help me in the weight room and with general manly things pretty well but not necessarily erection quality, I went over to his blog (DangerAndPlay) and he had a really good article on juicing beets for the nitric oxide benefits. Now he's since written I think three books on juicing as he is a big juicer (not in the testosterone sense haha).
For me I stopped juicing beats because I was concerned it might throw me out of a Ketogenic state, as it was the work of Taubes and Dr. Peter Attia that allowed me to lose that first 80 lbs. Frankly I just feel better when I am Ketogenic, but where I might have been off is that ingesting the beets pre-workout as part of a shake was probably fine. I can't recall but some of the target ketogenic diet folks (TKD) say right before or right after exercise the body can deal much better with the carbs, but I just didn't want to risk going out of Ketosis.
If you are not a low-carber then trying beets is probably worth it. In fact with it being a "super-food" supposedly there is good evidence to suggest having that beet is pretty healthy. When I juiced the beet, I did not bother peeling it. I just scrubbed the outside really well and cut it up into pieces that would fit in the juicer and it really worked well. Not quite as well as Gene's stack for me but it was a start in the right direction. If you don't want to take all the pills or (like I do) buy all the powders, or use the "tri-Amino" I would say give the beet a chance and see how you take it. Personally I cannot imagine eating the thing, I am not sure how I would choke it down.
