DEXA scan

VO2 max

The maximum amount of oxygen the body can take up during exercise — one of the strongest, well-documented predictors of lifespan, measurable in a sports diagnostics lab.

Strength Training

One of the single strongest predictors of healthy aging — it shapes muscle mass, bone density, and insulin sensitivity.

Menopause

The permanent cessation of menstruation caused by the ovaries ceasing function — a turning point involving significant metabolic, cardiovascular, and bone changes that calls for deliberate prevention.

Anastrozole on TRT

Anastrozole is the aromatase inhibitor most commonly used in the TRT community — and unlike exemestane, it has several real RCTs conducted directly in older and hypogonadal men. The picture from those trials is genuinely mixed: hormones respond predictably, but symptoms don't always follow, and one trial found a real, statistically significant drop in bone density.

MRI (Magnetic Resonance Imaging)

MRI uses a strong magnetic field and radio waves, not ionizing radiation, to produce images with exceptionally high soft-tissue contrast — brain, spinal cord, joints, and internal organs — at the cost of a much longer scan time than CT.

Mammography

An X-ray examination of the breast that is the primary method for screening detection of breast cancer at an early, asymptomatic stage — the only imaging test with mortality reduction documented in randomized clinical trials.

Echocardiography (Cardiac Echo)

Echocardiography is a real-time ultrasound test of the heart that — unlike an ECG, which only assesses electrical activity — shows chamber structure, valve function, and the strength of the heart muscle's contraction, with no radiation exposure.

Polysomnography (Sleep Study)

Polysomnography (PSG) is a comprehensive test that simultaneously records brain activity, eye movements, muscle tone, airflow, respiratory effort, blood oxygen saturation, and heart rhythm throughout a full night's sleep — the gold standard for diagnosing breathing disorders and assessing sleep architecture.

TRT and Bone Density: Does Testosterone Therapy Strengthen the Skeleton?

In men with diagnosed hypogonadism, a year of testosterone therapy measurably increases bone mineral density — especially in the spine and trabecular bone. But a large part of that effect doesn't come from testosterone itself, but from the estradiol it's converted into, which has practical consequences for patients also prescribed aromatase inhibitors.

Bone Density and Osteopenia: Why Prevention Starts Decades Before Menopause

Osteopenia — reduced but not yet clinically low bone mineral density — is often treated as a problem worth addressing only after menopause, or after a first worrying test result. Yet peak bone mass is usually reached before age thirty, and decisions made decades earlier — about training, diet, and screening — genuinely affect fracture risk at age 70 or 80. We check what the research on resistance training, calcium and vitamin D supplementation, and current screening guidelines actually shows.

TRT and Weight Loss — Does Testosterone Therapy Actually Help You Lose Weight?

Testosterone replacement therapy genuinely changes body composition in men with hypogonadism — less fat, more muscle — but it isn't a weight-loss drug, and the number on the scale after TRT often barely changes.

Strength Training for Women Over 40 — Where to Start

The decline in muscle mass, bone density, and metabolic rate after forty isn't a life sentence — it's largely reversible with strength training, even if you've never picked up a barbell before. This guide shows how to start safely, how much load you actually need, and what to avoid in the first few weeks.
