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.

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.
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.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
