TRT at 22: what young men with low testosterone should know

What did @drleprovost actually say?

The creator walks through a case of a 22-year-old male with fatigue, sleep issues, and a total testosterone of 450 ng/dL (reference range 280-1100). His free testosterone came in at 8.6 (range 1.9-27). The creator's take: these numbers are "kind of falling on the low end of normal" but still in range, and for a young guy, the right move is lifestyle changes, "natural supplements" that stimulate LH and FSH, and repeat testing rather than jumping straight to TRT. He also flags that LH and FSH should have been tested in the first place, which is a fair clinical point.

To his credit, he explicitly says: "if you're at this age, you probably do not want to be doing testosterone this way." That's a more cautious message than a lot of TRT-forward creators push.

Does the science back this up?

Largely, yes, with one significant caveat around the supplement claim. The overall clinical reasoning here is defensible. A testosterone of 450 ng/dL sits comfortably within the normal range for a young adult male, and guidelines do not support initiating TRT on that value alone.

The Endocrine Society's 2018 clinical practice guidelines (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism) recommend TRT only when testosterone is consistently below the lower limit of normal on at least two separate morning measurements, combined with clear signs and symptoms of hypogonadism. A single reading of 450 does not meet that threshold by any major guideline. The American Urological Association echoes this, noting that values below 300 ng/dL on two occasions are the typical trigger for treatment consideration.

The recommendation to test LH and FSH in a young male is textbook-correct. It distinguishes primary hypogonadism (testicular failure) from secondary hypogonadism (hypothalamic-pituitary dysfunction), which has significant implications for treatment options, including whether clomiphene or similar agents might be more appropriate than exogenous testosterone.

What did they get wrong (or right)?

The supplement claim is where this gets slippery. The creator says "natural supplements" with "herbs and minerals" can "restore and stimulate your LH and FSH thus increasing your testosterone naturally." That's a broad claim that the evidence does not firmly support.

Supplements like ashwagandha have some small, short-term trial data, but most are underpowered and industry-funded. A 2019 review by Lopresti et al. in Medicine found modest testosterone increases with ashwagandha in stressed men, but effect sizes were small and clinical significance unclear. Zinc and vitamin D matter if you're actually deficient, not as a blanket intervention. No supplement has demonstrated the ability to meaningfully correct symptomatic hypogonadism in a way that holds up to large, well-controlled trials.

The creator also says free testosterone at 8.6 is "falling on the low end." It is in the lower third of the reference range, but without age-specific norms being applied, this framing can feel more alarming than the data warrants. That said, he does credit lifestyle factors like stress and sleep as likely contributors, which is scientifically sound.

What he got right: recommend repeat testing, test LH/FSH, don't rush to TRT at 22. These are all appropriate positions.

What should you actually know?

If you are a young male with fatigue and a testosterone in the 400s, the honest answer is that you almost certainly do not need TRT right now, and starting it at 22 carries real long-term risks that often get glossed over in TRT content online.

Exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis, which means your body stops producing its own testosterone and, critically, stops producing the signaling needed for sperm production. For a 22-year-old, this is a fertility consideration that deserves serious discussion before any treatment starts. A 2021 review by Krzastek et al. in Urology Clinics of North America found that recovery of spermatogenesis after TRT cessation can take 12-24 months or longer and is not guaranteed.

The lifestyle recommendations in this video (sleep, resistance training, reducing alcohol, lowering stress) are genuinely evidence-backed for supporting testosterone levels. Leproult and Van Cauter (2011, JAMA) showed that sleep restriction to five hours per night reduced testosterone levels by 10-15% in young healthy men. That is a real, modifiable variable. Address those first. Then retest. Then, if numbers are still low and symptoms persist, have a detailed conversation with an endocrinologist or urologist, not just a TRT clinic.

Should you be worried about how this is framed?

The framing here is more responsible than average for TRT content on TikTok. The creator is not telling a 22-year-old to start injections. He is recommending lifestyle changes and retesting, which aligns with clinical guidelines. The supplement promotion is the weakest link, both scientifically and in terms of commercial transparency. Viewers should ask what specific supplements are being recommended and whether the creator or platform has a financial relationship with those products. "Natural supplements" is a marketing category, not a medical one. Treat it accordingly.
