Dr. Gillett opens the supplementation section with creatine, praising its multi-mechanism benefits: backup ATP for mitochondria, amino acid synthesis support, oxidative stress reduction, and a mild boost to total testosterone and DHT conversion. Huberman immediately surfaces the popular anxiety that creatine causes hair loss by raising DHT. Gillett's response is definitive: creatine doesn't push DHT to supraphysiologic levels — it just returns the testosterone-to-DHT conversion balance to what genetics would naturally dictate. In individuals with minimal 5-alpha reductase activity, it may actually normalize an otherwise suppressed DHT. Hair loss is not a valid reason to avoid creatine. Beta-alanine enters the picture as an alternative for the minority who are creatine non-responders, helping with amino acid synthesis and methionine/homocysteine processing at 1–3 grams per day. For creatine responders, adding beta-alanine is only useful if blood tests show persistently elevated homocysteine.
Creatine slightly increases DHT, but only to what your genetics naturally allow — it won't push androgens to supraphysiologic levels. Hair loss is not a valid reason to avoid creatine, which also boosts ATP backup, reduces oxidative stress, and mildly raises total testosterone.
Hair loss is not a valid reason to avoid creatine; it merely resets the natural testosterone-to-DHT conversion balance and won't push androgens to supraphysiologic levels.
L-carnitine shuttles nutrients into mitochondria and — critically — increases the density of androgen receptors in the cell cytoplasm. This means testosterone binds to more receptors even without any change in testosterone levels, amplifying hormonal effect.
