The person you love is either raising your hormones or destroying them, and most people have no idea which one is happening to them.

John Gray wrote Men Are from Mars, Women Are from Venus, the number one bestselling book of the entire decade and one of USA Today's top 10 most influential books of the last quarter century. His books have been translated into 45 languages across more than 100 countries. But what most people miss is that Gray is also a pioneer in the intersection of hormonal health, brain optimization, and human performance, a biohacker before the word existed. His newest book, Men Are from Mars for Women Only: Be Happy With or Without a Man, is the first in a six-part series packed with cutting-edge insights on relationships, biology, and longevity. 

Host Dave Asprey and John Gray go deep on the hormonal mechanics of desire, attraction, and emotional regulation, covering why societal testosterone collapse is driving relationship breakdown, how estrogen and testosterone function as a polarity system in both men and women, and why the relational environment you create every day is either building or destroying your biological potential. They also cover lithium orotate as a brain optimization supplement, the anti-aging power of semen retention, pre-digested protein as a nootropics-adjacent tool for brain healing, and how fasting and discipline directly boost testosterone. Gray even shares how he reversed early-stage Parkinson's using biohacking techniques and now maintains a testosterone level of 600 at age 74, with zero pharmaceutical support. 

This is essential listening for anyone serious about biohacking, longevity, anti-aging, supplements, human performance, brain optimization, functional medicine, metabolism, and hacking the biology of love and attraction.
