When training for a mental sport like chess, the foundational step is stabilizing energy by managing glucose metabolism, perhaps via intermittent fasting. Many athletes jump to "smart drugs" and stimulants, but this is ineffective if the underlying energy system is volatile and prone to crashes.

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.

The standard 5-gram dose of creatine is effective for muscle performance but insufficient to saturate the brain. To leverage creatine's neuroprotective and cognitive-enhancing effects—such as improved function when sleep-deprived or aging—a higher daily dose of 10 to 15 grams is necessary.

The standard 5g dose of creatine is largely absorbed by muscles, especially in active individuals. To achieve cognitive benefits like improved focus under stress, a higher dose of 10g or more is needed to create a "spillover" effect that saturates the brain with the compound.

The future of focus drugs isn't more powerful stimulants like Adderall. Instead, the breakthrough will come from substances that reduce cognitive 'noise' and craving, allowing for deliberate attention without over-activating the sympathetic nervous system and disrupting sleep. This is a subtle but critical shift in approach.

For late-night workouts, take 600-900mg of Alpha GPC. It increases acetylcholine for focus and alertness without being a classic stimulant like caffeine. Unlike traditional pre-workouts, it won't disrupt sleep and may even modestly increase REM sleep, aiding cognitive recovery and emotional processing overnight.

Specific auditory patterns can directly impact brain function. Research shows that 40 Hz binaural beats can increase striatal dopamine, a neurotransmitter crucial for motivation and focus. This leads to improved memory, faster reaction times, and better verbal recall. Listening for 30 minutes prior to a work session can prime your brain for high performance.

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.

Most people use stimulants like caffeine before studying for focus. However, to leverage their memory-enhancing properties via adrenaline release, it's more effective to consume them towards the end of or immediately after a learning bout. This aligns with the principle of spiking adrenaline post-encoding.
