@jordandalton_'s testosterone signs, fact-checked

What does this video actually claim?

Jordan Dalton lists five signs of "insanely high" testosterone: aggressive training with progressive overload, embracing discomfort like cold showers, fast recovery from workouts, waking up energized without caffeine dependency, and being decisive without overthinking.

The video frames these as indicators of naturally high testosterone levels. It's clearly aimed at young men who want to optimize their hormone levels through lifestyle changes. The tone suggests these behaviors both indicate and potentially boost testosterone.

But here's the problem: most of these "signs" are just markers of good health, fitness, and sleep hygiene. They don't specifically indicate testosterone levels at all.

Does the science back up these testosterone markers?

The research on behavioral markers of testosterone is pretty thin. A 2018 study by Gettler et al. in Evolution and Human Behavior found that testosterone levels in 624 men correlated weakly with risk-taking behavior, but the effect sizes were small (r = 0.12-0.18).

Morning erections (his "3 legs" reference) do correlate with testosterone levels. The Massachusetts Male Aging Study found that men with testosterone below 300 ng/dL were 3.1 times more likely to report erectile dysfunction. That's actually legit.

Recovery speed? There's no direct evidence that faster workout recovery indicates higher testosterone. The 2020 systematic review by Riachy et al. in Sports Medicine found that testosterone supplementation didn't significantly improve recovery markers in healthy men.

Decision-making speed isn't a validated testosterone marker either. If anything, some studies suggest higher testosterone can lead to more impulsive decisions, not better ones.

What did he get mostly right?

Dalton correctly identifies that progressive training and testosterone have a bidirectional relationship. A 2016 meta-analysis by Riachy et al. found that resistance training can boost testosterone by about 15-20% in healthy men, though the effect is modest.

The energy and libido connection is solid science. Low testosterone (hypogonadism) is clinically defined partly by fatigue and reduced sexual function. Normal total testosterone ranges from 300-1000 ng/dL, and men below 300 ng/dL often report these exact symptoms.

He's also right that these behaviors can support healthy testosterone levels. Sleep quality, resistance training, and stress management all influence hormone production. Just don't expect dramatic changes from cold showers alone.

What's the real way to know your testosterone levels?

You need blood work, period. Total testosterone should be measured between 7-10 AM when levels peak naturally. Free testosterone and SHBG (sex hormone-binding globulin) give you the complete picture.

The symptoms Dalton describes could indicate low testosterone. But they could also mean you're depressed, sleep-deprived, overtrained, or just out of shape. A 2017 study in JAMA found that 39% of men with low testosterone symptoms actually had normal hormone levels.

If your total testosterone is consistently below 300 ng/dL with symptoms, that's when testosterone replacement therapy becomes a medical conversation. The 2020 AUA guidelines recommend two separate morning measurements before considering treatment.
