Essentials: Tools for Hormone Optimization in Males | Dr. Kyle Gillett

Essential biomarkers for assessment

Monitor total testosterone alongside SHBG (sex hormone binding globulin) or free testosterone to understand bioavailable hormone levels, as SHBG binds androgens and affects their activity in tissues.

Testing frequency protocol

Using shared decision-making with a physician, retest blood work approximately every 6 months to track hormonal trends and development across the lifespan.

TRT rarely appropriate for young men

Testosterone replacement therapy is almost never justified for men in their 20s-30s with levels in the normal 300-900 ng/dL range, except in rare medical conditions like Kallmann syndrome.

Caloric restriction risks for lean individuals

While beneficial for overweight men, caloric restriction in lean individuals raises SHBG and lowers free androgens by reducing hormone building blocks and creating a catabolic state.

Exercise duration limits

Limit vigorous exercise to 3-4 sessions weekly, never exceeding 1 hour per session, as longer durations become hormonally counterproductive and unsustainable.

Critical nutrients for development

Prioritize dairy for IGF-1 (supporting bone density and growth through age 25), vitamin D for testosterone production, essential fatty acids for brain development through age 30, and prebiotic fiber to establish lifelong gut microbiome health.

Avoid extreme diets in youth

Pure carnivore or vegan diets in teens and early 20s significantly decrease free androgens and impair development, though they may be reasonable options after age 25.

Creatine for DHT optimization

Creatine slightly increases total testosterone and conversion to DHT, but does not accelerate hair loss beyond natural genetic predisposition since it doesn't create supraphysiological levels.

L-carnitine dosage and mechanism

Take 1-5 grams daily of oral L-carnitine (which has only 10% bioavailability) to increase androgen receptor density in cells and shuttle nutrients into mitochondria, with no cycling required.

TMAO risk mitigation

High-dose carnitine and choline convert to TMAO (potential carcinogen) via gut bacteria; offset this risk with garlic containing allicin or berberine, or optimize gut microbiome health.

Betaine for non-responders

If unresponsive to creatine or with elevated homocysteine, supplement 1-3 grams of betaine to support amino acid synthesis and methionine processing.

Stress undermines all pillars

Poor stress management disrupts diet, exercise, and sleep patterns, creating a cascade that negatively impacts hormonal optimization.

Purpose as hormonal support

Self-actualization and finding purpose (Maslow's hierarchy) supports endocrine health; goals can evolve over time and should be regularly reassessed rather than fixed.
