What did @onehottrail actually say?
The creator reviewed someone else's bloodwork showing high SHBG (119), which they correctly identified as suppressing free testosterone despite a normal total number. They connected high SHBG to excess dietary iron, referenced LH as a readout of HPG axis function, and pushed back on the idea that "spicy luteizing hormone" from raw honey meaningfully raises testosterone. Their own peak free testosterone was 22.87 ng/dL at a mid-range LH of six. They also noted LH is pulsatile, making single-draw values unreliable. The honey claim came from someone else in the video, and the creator explicitly distanced themselves from it.
Does the science back this up?
Mostly, yes, with one significant gap. The SHBG-free testosterone relationship is well-established. High SHBG binds testosterone with high affinity, leaving less bioavailable for androgen receptors. Pugeat et al. (1996, Journal of Clinical Endocrinology and Metabolism) confirmed that total testosterone can appear normal while free testosterone is clinically low when SHBG is elevated. The creator is right to flag this.
The LH-as-HPG-axis-gauge framing is also legitimate. Rastrelli et al. (2018, Best Practice and Research Clinical Endocrinology and Metabolism) describe how elevated LH with low testosterone signals primary or compensated hypogonadism, exactly what the creator described during their "seed oil experiment." The point about LH being pulsatile is supported by Veldhuis et al. (1987, Journal of Clinical Endocrinology and Metabolism), who documented 8 to 15 LH pulses per 24 hours in healthy men, making a single draw a snapshot, not a picture.
The honey-raises-LH claim is where things fall apart. There is no peer-reviewed evidence that raw honey directly stimulates LH secretion in humans at realistic dietary doses. The creator was right to reject it.
What did they get wrong (or right)?
The iron-to-SHBG connection is the weakest link in the chain. The creator states that overconsumption of iron raises SHBG, citing a ferritin of 311 ng/mL as evidence. High ferritin is associated with iron overload, and iron overload can cause secondary hypogonadism through pituitary and testicular damage, but the direct mechanism connecting dietary iron excess to elevated SHBG specifically is not well-supported in the literature. Valenti et al. (2009, Gut) documented hypogonadism in hereditary hemochromatosis, but that is a genetic iron loading disorder, not simply eating iron-rich food. Drawing a line from ferritin at the high end of normal to SHBG elevation is speculative, and the creator presents it as settled without the appropriate caveats.
On the other hand, the creator deserves credit for correctly distinguishing total from free testosterone, correctly characterizing LH as a system readout rather than a simple dial to turn up, and being intellectually honest about their own data showing high LH with lower testosterone during poor dietary conditions. That is good science communication.
What should you actually know?
SHBG elevation is real and clinically significant. If your total testosterone looks fine but you feel symptomatic, free testosterone and SHBG are worth measuring. Reference ranges for free testosterone vary by lab method, but calculated free testosterone below roughly 9 ng/dL in men under 50 is generally considered low by most clinical guidelines (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism).
Ferritin at 311 ng/mL is worth discussing with a clinician, but it does not automatically mean iron overload is tanking your testosterone through SHBG. Many things elevate SHBG: aging, hyperthyroidism, liver disease, low androgen states, and certain medications. Blaming one ferritin reading is reductive.
- LH interpretation requires context. High LH with low testosterone suggests the testes are struggling. Low LH with low testosterone suggests a central (brain/pituitary) problem. One draw without context tells you little.
- Raw honey has no credible mechanism for raising LH in humans. Fructose content in honey can actually be metabolically problematic in excess.
- A total testosterone of 1400 ng/dL is above the standard adult male reference range of roughly 300 to 1000 ng/dL (Bhasin et al., 2018). Whether that is "optimal" or an outlier worth chasing depends entirely on your clinical picture, not a number on a screen.
Should you try to replicate this person's approach?
Not without a clinician reviewing your own bloodwork first. Total testosterone of 1400 ng/dL is at the ceiling of most lab reference ranges. For some men that is their natural baseline; for others it would indicate an issue worth investigating. Free testosterone, SHBG, LH, FSH, and a metabolic panel together give a far more useful picture than any single marker. Anyone selling you a food hack to spike LH is selling you a story, not a mechanism.
