What does this video actually claim?
Justin Malik argues that "normal" testosterone ranges aren't good enough because they're based on a "diseased population." He suggests men should pursue testosterone replacement therapy (TRT) even with normal lab values if they want better energy, libido, and strength.
It's a provocative take that's become popular in fitness circles. But it oversimplifies how testosterone ranges are actually determined.
Are testosterone ranges really based on "diseased" populations?
No, that's not how reference ranges work. Modern testosterone ranges come from healthy population studies, not sick people.
The recent guidelines from the American Urological Association (2018) define low testosterone as below 300 ng/dL based on data from healthy men across age groups. The Framingham Heart Study and European Male Ageing Study, which helped establish current ranges, specifically excluded men with chronic diseases, obesity, and medications that affect testosterone.
Yes, average testosterone levels have declined over decades. But that doesn't mean current ranges represent "diseased" populations. The decline likely reflects lifestyle factors like obesity and stress, not some conspiracy to keep men underperforming.
Can you have symptoms with "normal" testosterone?
Absolutely, and this is where Malik gets something right. The clinical reality is messier than lab ranges suggest.
Research by Zitzmann and Nieschlag (Clinical Endocrinology, 2001) found that men with testosterone between 230-350 ng/dL often experienced symptoms like fatigue and low libido, even though these levels technically fall within some lab ranges. Individual sensitivity to testosterone varies significantly.
However, jumping straight to TRT isn't the obvious answer. Sleep optimization, weight loss, and stress management can raise testosterone naturally. A study by Leproult and Van Cauter (JAMA, 2011) showed that one week of sleep restriction dropped testosterone by 10-15% in healthy young men.
What are the risks he doesn't mention?
Malik frames this as a simple optimization choice, but TRT carries real risks that he completely ignores.
The Testosterone Trials (Snyder et al., NEJM, 2016) found that men on TRT had increased risk of cardiovascular events. Long-term use can also suppress natural production permanently, cause infertility, and increase prostate growth. Once you start, stopping often leaves men worse off than before.
The "more is better" mindset also leads some men to pursue supraphysiological doses, which significantly increases risks of heart problems, mood swings, and other complications. TRT isn't like taking a vitamin.
What should men actually do?
Get proper testing first. That means multiple early morning testosterone measurements, not just one test after a bad night's sleep.
If levels are genuinely low (below 300 ng/dL) with clear symptoms, TRT can be life-changing. But if you're at 400-500 ng/dL, focus on lifestyle factors first. Weight loss alone can increase testosterone by 200-300 ng/dL in obese men, according to research by Niskanen et al. (Journal of Clinical Endocrinology, 2004).
Work with an endocrinologist or urologist who understands the nuances, not someone who profits from selling you hormones. The goal should be treating genuine deficiency, not chasing some idealized version of peak performance.
