TRT stress and anxiety: what the science says about testosterone and mood

What did @pear.pt2 actually say?

@pear.pt2 got blood work back and saw an LH of 0.2 and FSH of 0.1, then landed on two possible explanations: either "my HCG is fake" or he is "fucked for life" with permanent infertility. That binary framing is where things go sideways. Both conclusions skip over the most obvious explanation entirely.

To be fair, the emotional reaction makes sense. Seeing near-zero gonadotropins is alarming if you don't know what you're looking at. But this video, with 23.5K views, is spreading a misread of routine TRT physiology as if it were a medical crisis or a counterfeit HCG scandal. Neither is necessarily true here.

Does the science back this up?

No. Suppressed LH and FSH are not evidence of fake HCG. They are the expected result of exogenous testosterone use, full stop. This is not controversial in endocrinology.

Exogenous testosterone suppresses the hypothalamic-pituitary-gonadal (HPG) axis through negative feedback. The hypothalamus reduces GnRH pulses, which suppresses LH and FSH from the pituitary. This happens whether or not HCG is in the picture. HCG mimics LH at the Leydig cell level in the testes, but it does not restore measurable serum LH or FSH because those are downstream of the pituitary, and the pituitary is still suppressed by the testosterone signal. Coviello et al. (2005, Journal of Clinical Endocrinology and Metabolism) confirmed that HCG maintains intratesticular testosterone during androgen suppression without restoring gonadotropin levels. So an LH of 0.2 and FSH of 0.1 while on TRT and HCG is a textbook result, not a red flag for adulterated product.

What did they get wrong (or right)?

The claim that "my HCG is fake" because LH is suppressed is flat-out wrong. It reflects a misunderstanding of how HCG works in the context of TRT. HCG does not raise serum LH. It bypasses the pituitary and acts directly on the testes. You cannot use serum LH as a proxy for HCG activity.

The second claim, that he might be "fucked for life," is also not supported by these labs alone. HPG axis suppression from TRT is generally reversible, particularly in men who have not been on therapy for decades. Ramasamy et al. (2014, Fertility and Sterility) found that gonadotropin-based therapies, including HCG and FSH, can recover sperm production in the majority of hypogonadal men post-TRT, though recovery timelines vary. Permanent infertility from TRT alone, without a pre-existing condition, is not the default outcome.

What he got right: being proactive about blood work and monitoring fertility markers while on TRT is genuinely good practice. More TRT users should be doing this.

What should you actually know?

If you are on TRT and want to assess whether HCG is working, serum LH is the wrong test. Intratesticular testosterone levels are the relevant metric, but those are not measured by standard blood panels. Clinically, testicular volume maintenance and semen analysis are more practical indicators. Liu et al. (2009, Journal of Clinical Endocrinology and Metabolism) demonstrated that HCG dosing in TRT-suppressed men was associated with maintained testicular volume and intratesticular testosterone, independent of serum LH.

For anyone concerned about fertility on TRT, the right conversation is with a urologist or reproductive endocrinologist, not a TikTok comment section. Semen analysis is the actual fertility test here. A low LH on a standard panel tells you the HPG axis is suppressed. It does not tell you whether sperm production is happening, whether HCG is authentic, or whether fertility is permanently compromised.

• Serum LH and FSH being near-zero on TRT is expected, not diagnostic of fake HCG.
• HCG works at the testicular level and does not restore serum LH.
• Fertility concerns on TRT require semen analysis, not just hormone panels.
• TRT-induced suppression is generally reversible with appropriate clinical management.
