What did @itsjoshuastevenson actually say?
The creator argued that skipping HCG while on TRT is "a big mistake" even for men who don't want children. His core reasoning: exogenous testosterone shuts down your body's natural production, and HCG keeps some of that endogenous signaling alive so you don't become "fully reliant" on your dose. He also claimed higher testosterone doses are dangerous to the cardiovascular system and that HCG protects the endocrine system broadly.
He used a coffee tolerance analogy to suggest that without HCG, you'd need escalating testosterone doses over time, similar to needing more caffeine after years of daily use. He closed with a call to action directing viewers to click a link, suggesting his platform teaches the "right way" to do TRT. The transcript is garbled in places, likely from auto-captioning errors, but the core claims are identifiable and worth examining closely.
Does the science back this up?
Partially. The physiology is mostly right, but the practical conclusions are overstated. HCG does support intratesticular testosterone and testicular function during TRT. The cardiovascular risks of high-dose testosterone are real. But the claim that HCG prevents dose escalation the way he describes it lacks direct clinical evidence.
HCG is a luteinizing hormone (LH) analog. When exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis, HCG can stimulate Leydig cells directly, maintaining intratesticular testosterone (ITT) production. This is well-documented. Coviello et al. (2005, Journal of Clinical Endocrinology and Metabolism) showed that low-dose HCG co-administered with testosterone maintained ITT levels that testosterone alone suppressed by over 90%. For men who want to preserve fertility or testicular volume, this is genuinely useful data.
The cardiovascular claim also has legs. Hematocrit elevation from testosterone therapy is a documented concern. Eur J Endocrinol (Bachman et al., 2010) and subsequent studies link supraphysiologic testosterone to erythrocytosis, increased blood viscosity, and cardiovascular strain. The creator gets credit for flagging this.
Where the science gets thin: there's no strong clinical evidence that HCG co-administration prevents patients from needing higher testosterone doses over time. Testosterone tolerance doesn't work quite like caffeine tolerance, and conflating the two is a meaningful oversimplification.
What did they get wrong (or right)?
Let's be direct. The HPG axis suppression point is accurate. The fertility and testicular atrophy rationale for HCG is evidence-based. The cardiovascular risk of high-dose testosterone is real and underappreciated in TRT-content circles. These are genuine contributions to public understanding.
But the coffee analogy is a problem. Testosterone doesn't build receptor tolerance the way caffeine does with adenosine receptors. The mechanism is different. Some men do require dose adjustments over time, but this is more related to changes in SHBG, hematocrit management, or administration route than to a tolerance phenomenon. Presenting it as analogous to caffeine habituation is misleading and could cause men to unnecessarily add HCG based on faulty reasoning.
The claim that HCG "protects the endocrine system" broadly is vague and unsupported as stated. HCG maintains LH-dependent functions in the testes. It does not broadly protect all endocrine pathways disrupted by TRT, such as FSH suppression, which HCG does not fully restore. Coviello et al. and Hsieh et al. (2013, Journal of Urology) both note that FSH remains suppressed even with HCG use, which has implications for spermatogenesis that the creator ignores.
Also worth noting: the link he directs viewers to click raises questions about whether this is clinical advice or a sales funnel. That context matters when evaluating who benefits from the recommendation.
What should you actually know?
HCG is a legitimate clinical tool in TRT management, not a universal requirement. Whether it belongs in your protocol depends on your goals, your baseline labs, and a real conversation with a licensed provider who knows your history.
If you want to preserve fertility during TRT, HCG or alternatives like clomiphene are worth discussing with your doctor. Schlegel et al. and guidelines from the American Urological Association are clear that TRT alone impairs spermatogenesis and that adjunct therapies can mitigate this. If fertility is not a concern, the calculus changes. Some men on TRT do experience testicular atrophy and find it bothersome; HCG addresses this. Others don't prioritize it.
The cardiovascular risks of testosterone therapy are real and worth monitoring regardless of HCG use. Regular hematocrit checks, blood pressure monitoring, and dose management are not optional. HCG does not neutralize these risks.
No one on TikTok, including creators with good intentions, should be your primary source for hormone management decisions. The Endocrine Society's 2018 clinical practice guidelines on testosterone therapy remain the most reliable starting point for understanding what evidence-based care actually looks like.
