That stuff is loaded with toxic oxalates. Straight-up "natural" poison.
I get similar results from pomegranate juice and it tastes much better.
Also try maca powder
I don't chug on beeted off juice but I have ran after eating a suitable quantity of beetroot itself and I am absolutely convinced of it's performance enhancing ability.
Had beetroot today. Absolutely vile. Can't imagine me taking it long term.
I returned to using Beetjuice with a vengeance , just like Alicia Keys wearing make up again, after she said wearing make-up is accepting media exploitation .
I run with a guy that absolutely swears by beet capsules he takes before every workout he runs. Other people also seem to like Beet Elite.
Hate the juice, but I enjoy roasted beat root. I usually roast them with sweet potatoes, carrots, onion, garlic etc. and add them to quinoa or something similar
I'm a big BeetElite fan. I can't stomach straight up beet juice, but the black cherry version of theirs is pretty palatable. I definitely do get a "head rush" from it, and feel like my breathing is a bit easier at harder efforts.
The nitrate content of various beet-based products (and of beets themselves) varies enormously:

It is also equivocal whether nitrate supplementation has any beneficial effect on *endurance* performance, at least in trained athletes (it has a much larger effect on maximal muscle power - cf.
https://pubmed.ncbi.nlm.nih.gov/30001275
).
Thus, my standard response is "take two Beet It and call me in the morning"...that is, if you wish to experiment with beetroot juice at least that way you have a reasonable shot (pun intended) of getting in the right "therapeutic range". Just watch out for GI distress, pink urine or stools, and, yes, the relatively high oxalate content if you are prone to kidney stones. (Note that there are several KNO3 products on the market that bypass this issue...but again, the available evidence suggests that well-trained endurance athletes don't benefit from nitrate supplementation.)
My mom made me eat beets when I was about 4 years old. I threw them up. Never ate any since.
Where is the sense in the claim that having excess nitric oxide around would help anything at all? Its main function is to cause local vasodilation, and more than enough is secreted by the endothelial and blood cells to achieve that.
This article is the most informative thing a runner can possibly read about how their "aerobic engine" works.
Beet Elite is an interesting product. In addition to beet powder, it is spiked with nitrite, and thus elevates plasma nitrite and (breath) nitric oxide more rapidly than other beet/nitrate-based products. However, it doesn't contain all that much nitrate, and in fact a study from Andy Jones's lab showed that the earlier elevation in plasma nitrate and nitrite is not maintained over time. It would therefore be a better choice for"topping up" nitric oxide bioavailability during, e.g., the later parts of a long bike race than as a pre-race supplement.
As I described it in a recent grant application: "Many people finds beetroot juice to be highly unpalatable".
OTOH, I have had a roasted beet, spinach, and feta cheese appetizer that I thought was quite tasty.

Although nitric oxide was first *identified* due to its role as a vasodilator, in fact it is involved in many physiological processes. Thus, in grants I describe it as an "ubiquitous signaling molecule", whereas in talks I refer to it as "promiscuous, i.e., involved in many relationships" (which always draws a laugh).
With all that said, you're right, when you look carefully at the literature the evidence that nitrate supplementation improves performance in well-trained *endurance* athletes is equivocal at best. Indeed, even in moderately trained/physically active subjects it only increases sustainable power by ~2%. In contrast, the effects on maximal (sprinting) power are 2-3X greater. Thus, that seems to be the real story/application, especially in subject groups that are relatively deficient in nitric oxide (e.g., heart failure patients, the elderly).

so how is extra NO supposed to help non-deficient people?
You can synthesize the stuff yourself, you don't have to eat nitrates at all.

Vegans have a serious problem with facts.

So do you.
