Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — Topical Testosterone

When it comes to topical testosterone therapy, more is not always better. Dr. Allison Smith of ZRT Laboratory explains the U-shaped curve phenomenon — where both too little and too much testosterone produce the same symptoms — and why starting at low doses and titrating carefully is essential. She also outlines the key markers to check when a man’s testosterone numbers look good on paper but his symptoms persist.

Explore why many men on topical testosterone replacement therapy may be unintentionally over-dosed due to outdated serum testing methods and misunderstood dosing principles. Learn how saliva and dried blood spot testing better reflect bioavailable testosterone delivered to tissues, why physiological dosing matters, and how excessive testosterone may suppress natural hormone production, reduce receptor sensitivity, and negatively affect long-term symptom management and hormonal balance.

From the age of 45, most men experience a gradual decline in testosterone and DHEA — yet many put their symptoms down to “just getting old.” Andropause is real, measurable and manageable. Discover the symptoms, the truth about testosterone replacement therapy, and the lifestyle and testing strategies that help men age well rather than rapidly.
