Dr. Alexander Landfield
Board-Certified Neurologist & Medical Director
Testosterone is the primary male sex hormone, but its influence extends far beyond sexual function. It plays critical roles in energy production, mood regulation, muscle maintenance, bone density, cardiovascular health, and cognitive function. When testosterone levels decline — a process that begins gradually in the early 30s and accelerates with age — the effects can be far-reaching. At Rani Beauty Clinic in Renton, WA, Dr. Alexander Landfield provides physician-supervised testosterone replacement therapy for men whose blood work and symptoms confirm clinical deficiency.
Symptoms of low testosterone include persistent fatigue, decreased motivation, reduced libido, erectile difficulties, loss of muscle mass, increased body fat especially around the abdomen, mood changes including irritability and depression, and difficulty concentrating. These symptoms develop gradually, and many men attribute them to normal aging or stress rather than recognizing them as signs of a treatable hormonal deficiency.
Testosterone replacement therapy at Rani Beauty Clinic is available in several forms, and Dr. Landfield helps each patient choose the delivery method that best fits their lifestyle and preferences. Options include weekly or biweekly intramuscular injections, which provide consistent levels and are the most cost-effective method, and topical gels or creams applied daily. The choice depends on patient preference, insurance coverage, and how each individual responds to different delivery systems.
Monitoring is an essential component of safe TRT. Dr. Landfield orders regular blood work including total and free testosterone, estradiol, hematocrit, PSA, and lipid panels to ensure levels remain in the optimal range and to catch any potential side effects early. Estrogen management is particularly important, as testosterone can convert to estradiol through aromatization, potentially causing water retention, mood changes, or gynecomastia. Proactive monitoring and dosage adjustments keep patients feeling their best while maintaining long-term safety.
