15hz is an independent audio lab for state control – built by myself, being a biohacker who stress‑tests every protocol on his own nervous system before releasing it. The core idea: what happens when you combine precise brainwave frequencies, respiratory stress, hypoxia and targeted supplementation into one integrated system? Instead of “meditation music”, you get protocols – complete stacks that tell your brain and body exactly what to do. Each 15hz kit includes: ### Engineered isochronic audio targeting specific bands like SMR‑range low beta around 12–15 Hz for calm, focused alertness, or deeper theta and delta for shutdown and sleep. ​ ### Structured breathing and movement drills for VO2max, CO2 tolerance and vagus‑nerve resilience. ### Optional priming with things like Lion’s Mane for NGF/BDNF support and niacin for short, intense vasodilation, enhancing circulation and neuroplastic stress adaptation. ​ Sessions are built from real data – treadmill intervals in heart‑rate zone 5, static apnea work, hill repeats and sleep tracking – not from vague wellness promises. Every product is a digital toolchain: frequency engine, operations manual, and clear use‑cases so you don’t have to guess, only execute. 15hz is for people who treat their nervous system like high‑performance hardware: runners, Hyrox athletes, developers, founders, deep‑work addicts – anyone who believes adaptation beats affirmation.
