Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — testosterone and body composition

Andropause — often called male menopause — describes the gradual decline in testosterone and other key hormones that affects many men from their forties onwards. Unlike the relatively abrupt hormonal shift of female menopause, andropause develops slowly, making its symptoms easy to dismiss as normal ageing or stress. Yet the hormonal changes involved — including declining testosterone, rising oestrogen, cortisol dysregulation, and thyroid dysfunction — can significantly affect energy, mood, body composition, sexual health, and cognitive function. This article explains what andropause is, the key hormones involved, how to recognise its symptoms, and how comprehensive hormone testing can identify the specific imbalances driving your symptoms.

An FDA-approved testosterone gel was shown to significantly increase cardiovascular risk in older men — but does this mean testosterone therapy is dangerous? ZRT Laboratory’s research suggests the real problem lies in how testosterone is measured. Venous serum testing dramatically underestimates tissue exposure to topical testosterone, leading to pharmacological overdosing that goes undetected. This article explains why the testing method matters as much as the dose.

Discover why topical testosterone replacement therapy is frequently over-prescribed and how outdated serum testing methods may fail to reflect true hormone bioavailability. Learn how saliva and dried blood spot testing provide a more accurate picture of tissue hormone delivery, why physiological testosterone dosing matters, and how excessive testosterone may suppress natural production, reduce receptor sensitivity, and impact long-term hormonal balance, energy, mood, libido, and overall men’s health.
