What did @agelessmenshealth actually say?
Alex from Ageless Men's Health walked through the differences between oral and injectable testosterone, leaning hard toward injectables. He said oral testosterone has "inconsistent" absorption tied to food intake, while injections provide "more stable and sustained testosterone levels." He also claimed injections "bypass the digestive system, reducing potential liver strain" and that oral formulations are newer with less established safety data. The video ends with a call to schedule a consultation.
That's a fairly reasonable overview, but there's a specific factual error buried in the middle that undermines the whole segment, and the liver claim is more nuanced than he lets on.
Does the science back this up?
Partially. The absorption variability claim for oral testosterone is real, but the liver strain framing is outdated and doesn't apply cleanly to modern oral formulations. Injectable testosterone's efficacy profile is well-documented, but calling oral options categorically riskier is a stretch given current evidence.
Testosterone undecanoate (Jatenzo, Tlando, Kyzaiq) is the primary oral formulation approved in the U.S. These are not 17-alpha alkylated compounds, which is the older class of oral androgens actually linked to hepatotoxicity. Swerdloff et al. (2020, Journal of Clinical Endocrinology and Metabolism) showed that oral testosterone undecanoate achieved therapeutic serum levels in roughly 87% of men, with meal-dependent absorption being a real but manageable variable. The liver signal in that trial was not clinically significant.
For injectables, the evidence base is stronger simply because testosterone cypionate and enanthate have been used for decades. Bhasin et al. (2010, NEJM) remains a key reference for injectable testosterone's efficacy in hypogonadal men, confirming stable trough levels with weekly or biweekly dosing.
What did they get wrong (or right)?
There is a clear scripting error in this video that should not go unaddressed. Alex says "oral testosterone is intramuscularly administered" when he visibly means to say injectable testosterone. That is a factual mix-up that could genuinely confuse viewers who are early in researching TRT options.
On the liver claim: the framing that injectables reduce "liver strain associated with oral medications" is misleading when applied to FDA-approved oral testosterone undecanoate. That liver risk narrative comes from older, alkylated oral androgens like methyltestosterone, which are largely off the market. Saying modern oral testosterone carries liver risk without that distinction is not accurate.
What he got right: food-dependent absorption for oral testosterone undecanoate is real and documented. The FDA label for Jatenzo specifically requires administration with food. He also appropriately deferred to healthcare providers for treatment decisions, which is the correct call.
What should you actually know?
If you are comparing oral and injectable testosterone, the actual decision points are more practical than the video suggests. Injection frequency, needle comfort, and consistent scheduling matter for injectables. Meal timing and the twice-daily dosing schedule matter for oral options. Neither form is universally superior.
The liver concern is largely a non-issue with approved oral testosterone undecanoate at therapeutic doses, based on current trial data. If a provider or content creator is still invoking the liver argument to steer you away from oral testosterone, ask them specifically which formulation they mean. Alkylated oral androgens and modern testosterone undecanoate are not the same thing.
A 2022 review by Khera et al. in Urology Clinics of North America noted that both delivery methods can achieve symptom relief in hypogonadal men when dosed appropriately, and that patient preference and lifestyle factors should be weighted heavily in the choice. That is a more accurate frame than "injectables are more stable, therefore better."
- Oral testosterone undecanoate is FDA-approved and does not carry the same hepatotoxicity risk as older alkylated oral androgens.
- Injectable testosterone has a longer evidence base, but that reflects history of availability, not inherent superiority.
- Absorption variability with oral TRT is real, but manageable with consistent meal timing.
- The "intramuscularly administered" line in the video was a scripting error that reversed the route of administration.
