Dr. McAlpine's hormone therapy claims lack key context

What does this TikTok actually claim?

Dr. Alistair McAlpine argues that hormone optimization therapy should be based on symptoms and blood tests, not just age. He lists fatigue, brain fog, low libido, weight gain, and poor sleep as warning signs that aren't just normal aging.

The video suggests people in their 30s and 40s might need hormone therapy if they have these symptoms plus "suboptimal" hormone levels on blood work. McAlpine frames this as restoring function rather than anti-aging.

Does the science support starting hormone therapy early?

The evidence is mixed, and McAlpine oversimplifies the decision-making process. The American Urological Association's 2018 guidelines recommend testosterone therapy only for men with both symptoms AND testosterone levels below 300 ng/dL on two separate morning tests.

Most randomized trials focus on older men with clear hypogonadism. The Testosterone Trials (Snyder et al., NEJM, 2016) studied men 65 and older with testosterone under 275 ng/dL. They found modest improvements in sexual function and mood, but no benefit for vitality or walking distance.

For younger men with "low-normal" testosterone (300-400 ng/dL), there's little high-quality evidence supporting treatment.

What's problematic about the "suboptimal" framing?

McAlpine's use of "suboptimal" hormone levels is where this gets dicey. Normal testosterone ranges from roughly 300-1000 ng/dL, but many anti-aging clinics push treatment for men in the 400-500 range.

The problem? Those symptoms McAlpine lists (fatigue, brain fog, weight gain) have dozens of potential causes. A 2017 study in JAMA Internal Medicine (Mulhall et al.) found that 60% of men seeking testosterone therapy had normal levels when properly tested.

Sleep apnea, depression, obesity, and diabetes can all mimic low testosterone symptoms. Treating the number instead of finding the root cause often misses the actual problem.

What are the real risks he doesn't mention?

McAlpine doesn't discuss the downsides of testosterone therapy, which is a major omission. Testosterone therapy can reduce sperm production and fertility, sometimes permanently.

The FDA requires warnings about cardiovascular risks, though the data remains controversial. A 2019 meta-analysis (Corona et al., Andrology) found no increased heart risk, but earlier studies raised concerns.

There's also the psychological aspect. Starting hormone therapy in your 30s or 40s often means lifelong treatment, since your natural production may not recover after stopping.

What should you actually know about hormone therapy?

The decision to start testosterone therapy should involve clear diagnostic criteria, not just symptom checklists. Two morning testosterone levels below 300 ng/dL, confirmed symptoms, and ruling out other causes is the standard approach.

For men with genuine hypogonadism, testosterone therapy can be effective. The Testosterone Trials showed meaningful improvements in sexual function and some mood parameters in older men with very low levels.

But if you're experiencing fatigue and brain fog, start with the basics: sleep study, depression screening, vitamin D levels, and thyroid function. These are often more treatable and safer than jumping to hormone therapy. Visit our TRT hub for more evidence-based information about testosterone replacement therapy.
