While many biohackers use Pinealon (EDR) for its effects on REM sleep, its original Soviet research points to a different application. Studies on athletes showed it helped them maintain cognitive performance on tests even after being maximally exhausted from training, suggesting its power as a nootropic for high-stress situations.

Shifting to a low-carbohydrate diet increases baseline cortisol because the body needs to mobilize energy stores more actively. This can lead to feelings of being "wired but tired" and can disrupt sleep, especially during the adaptation period.

High levels of the stress hormone cortisol, combined with low levels of serotonin, increase the "hydraulic pressure" for aggression. This state primes the sympathetic nervous system for reactivity. Managing cortisol through tools like sunlight exposure, sauna, or ashwagandha can directly reduce the biological tendency toward aggression.

The primary stress hormone, cortisol, is not just a signal; it's directly toxic to brain cells, especially in the hippocampus, the region responsible for memory and emotion. This makes stress management critical for preventing cognitive decline.

Cortisol isn't just a negative stress hormone. The "cortisol awakening response" is a natural, healthy spike that provides the energy and alertness needed to start your day. Optimizing this spike is crucial for setting your entire daily rhythm.

A healthy, well-rested brain produces enough creatine on its own. However, under metabolic stress like sleep deprivation or intense focus, supplementation is crucial. The required dose increases with stress levels, potentially reaching 20-30g for acute situations, far higher than typical muscle-building doses.

The brain's glymphatic waste clearance system works best at night. Mark Burnett suggests taking his supplement in the evening and sleeping on an incline using a wedge pillow to physically assist this natural drainage process, potentially boosting the supplement's effects.

Contrary to popular low-carb diet advice, consuming starchy carbohydrates in the evening can significantly improve sleep quality. Carbs help lower cortisol, the body's stress hormone, which needs to be low at night for restorative sleep. This explains why many low-carb dieters struggle with sleep disruption.

Creatine is widely known for muscle performance, but its more significant, lesser-known benefit is enhancing brain function. It is particularly effective during periods of stress, sleep deprivation, or high cognitive demand by helping the brain regenerate energy more quickly.
