Biomarker testing for longevity, essential labs
Biomarker testing for longevity goes well beyond a standard annual physical, covering markers like ApoB, fasting insulin, hs-CRP, hormones including testosterone, and inflammation indicators that reveal early signs of aging-related dysfunction long before symptoms or...
Does testosterone cause hair loss or baldness
Testosterone itself does not directly cause hair loss. The real driver is dihydrotestosterone (DHT), a byproduct created when testosterone is converted by an enzyme called 5-alpha reductase. Whether DHT causes hair loss depends almost entirely on genetic sensitivity...
Testosterone, anger and mood swings explained
The relationship between testosterone and anger is more complex than popular culture suggests. Research shows that low testosterone, not high testosterone, is more commonly linked to irritability, mood swings, and reduced frustration tolerance in men. The "roid rage"...
Key testosterone biomarkers every man should test
The key testosterone biomarkers every man should test include total testosterone, free testosterone, SHBG, LH, FSH, and estradiol. Together, these markers provide a far more complete picture of hormonal health than total testosterone alone, since two men with...
Perimenopause testing, hormones and key labs
Perimenopause testing typically includes FSH, estradiol, LH, and TSH as core hormone labs, with additional tests like progesterone, testosterone, and DHEA-S adding a more complete picture. Because hormone levels fluctuate significantly during this transition, a single...
High intensity interval training and testosterone
High intensity interval training (HIIT) has been shown in multiple studies to increase testosterone levels, both immediately after a single session and over weeks of consistent training. Research suggests HIIT produces a stronger hormonal response than steady,...
