Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — SHBG testing

Why a Hormone Profile Is Better Than a Single Test. When men experience hormone-related symptoms (like low libido, fatigue, weight gain, or mood changes), it’s rarely just one hormone causing the issue. A simple testosterone check may miss the bigger picture.

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.
