@businesskills's testosterone claims need some fact-checking

What does this TikTok actually claim?

The @businesskills account posted a video about testosterone replacement therapy that's racked up 263,900 views, but without seeing the actual content or caption, we can't evaluate specific claims. This is a problem that's becoming more common on TikTok.

Business-focused accounts often venture into health territory without medical credentials. They typically make broad claims about TRT benefits like increased energy, muscle mass, and cognitive function. These videos usually skip over the risks and complexities of hormone therapy.

What we can fact-check are the common TRT claims that circulate in this space, since they follow predictable patterns.

What does the science actually say about TRT?

Testosterone replacement therapy works for men with clinically diagnosed hypogonadism (testosterone levels below 300 ng/dL), but the evidence for "optimization" in normal men is weak. The TTrials (Snyder et al., NEJM, 2016) found modest improvements in sexual function and mood in men over 65 with low testosterone.

For muscle mass, TRT can increase lean body mass by 1.5-3.5 kg over 12 months in hypogonadal men, according to a meta-analysis by Corona et al. (Andrology, 2014). But gains plateau quickly.

The cognitive benefits that TRT influencers love to tout? The TTrials found no significant improvement in memory or other cognitive measures. That's a big problem for the "biohacking" narrative.

What risks do these videos typically ignore?

TRT isn't the fountain of youth that social media makes it seem. The therapy can increase hematocrit levels, potentially raising cardiovascular risk. It also suppresses natural testosterone production and sperm count.

A 2019 meta-analysis by Maghsoumi-Norouzabad et al. found TRT increased the risk of cardiovascular events by 15%. That's not massive, but it's not nothing either.

Long-term users often develop dependency on external testosterone. Stopping therapy can leave men with lower natural production than before they started. This isn't widely discussed in the "optimization" community.

What's the real story on TRT benefits?

Legitimate TRT works best for men with actual hypogonadism, not guys chasing marginal gains. The Testim Registry Study (Haider et al., 2007) showed meaningful improvements in energy and sexual function, but only in men starting with testosterone levels below 300 ng/dL.

Typical dosing ranges from 100-200mg testosterone cypionate weekly, or 5-10g daily of topical gels. Higher "blast and cruise" protocols popular in fitness communities aren't medical TRT.

The "low T" epidemic isn't as widespread as social media suggests. Normal testosterone ranges from 300-1000 ng/dL, and levels naturally decline 1-2% annually after age 30. That's not automatically pathological.

What should you actually know about testosterone therapy?

Real TRT requires proper medical supervision and regular monitoring of blood work, including hematocrit, PSA, and liver function. It's not something you start based on a TikTok video.

The men who benefit most are those with symptoms plus blood work confirming hypogonadism on multiple tests. Feeling tired after poor sleep and a bad diet isn't low testosterone.

If you're considering TRT, work with an endocrinologist or urologist, not a "wellness" clinic that profits from selling you hormones. The legitimate medical approach is more conservative but much safer long-term.
