What We Treat › Low Testosterone / TRT
Physician-Directed Care · Scottsdale AZ

Not Yourself Anymore?
It Might Be Your T.

Low testosterone is the most underdiagnosed condition in men's health. It doesn't just affect libido — it drains your energy, kills your drive, adds fat to your midsection, blunts your thinking, and makes you feel like a dimmer version of who you used to be. Physician-directed TRT restores what time and biology have taken away.

What Low Testosterone Actually Feels Like

Low testosterone doesn't announce itself. It creeps in gradually over years — and most men attribute its symptoms to stress, aging, or "just getting older." These are the signs the lab work will confirm.

Profound fatigueNot tiredness from a bad night — a deep, persistent exhaustion that sleep doesn't fix. Low testosterone reduces red blood cell production and cellular energy output simultaneously.
🧠
Brain fog & cognitive slowingTestosterone receptors are densely distributed throughout the brain. Low levels reduce working memory, processing speed, and verbal fluency — often misattributed to stress or aging.
🫃
Abdominal fat accumulationLow testosterone promotes visceral fat storage — especially around the midsection. This fat is metabolically active and perpetuates the cycle: visceral fat converts testosterone to estrogen, further lowering T levels.
💪
Muscle loss despite trainingTestosterone is the primary anabolic hormone driving muscle protein synthesis. Without adequate levels, muscle mass declines even with consistent resistance training and adequate protein intake.
😔
Low mood & motivationTestosterone regulates serotonin and dopamine systems. Men with low testosterone consistently show higher rates of depression and anxiety — and these symptoms often resolve with TRT, not antidepressants.
🔥
Reduced libidoThe most recognized symptom — but often not the most disruptive. Reduced sexual interest frequently accompanies broader losses in motivation, competitiveness, and engagement with life.
🦴
Joint aches & reduced recoveryTestosterone is anti-inflammatory and essential for bone density and connective tissue health. Low levels produce diffuse joint pain, slower injury recovery, and accelerated musculoskeletal aging.
😴
Sleep disruptionLow testosterone is associated with reduced sleep quality and increased rates of sleep apnea. Optimizing testosterone often improves sleep architecture — further reinforcing the energy and mood improvements from TRT.

Why Testosterone Matters More Than You Think

Testosterone is not just a "sex hormone." It is a master regulator of male physiology — affecting energy metabolism, cognitive function, cardiovascular health, bone density, and immune regulation.

01
Age-Related Decline
Testosterone peaks in the early 20s and declines at approximately 1% per year after age 30. By age 45, the average man has lost 15–20% of his peak testosterone. By 55, that number exceeds 25%. Standard lab "normal" ranges are extremely wide — encompassing the 20-year-old and the 80-year-old in the same reference interval. A man at the low end of "normal" may be functioning at testosterone levels that are physiologically suboptimal for his age and activity level.
02
The Visceral Fat Cycle
Visceral adipose tissue contains high levels of aromatase — the enzyme that converts testosterone to estrogen. As testosterone declines and visceral fat accumulates, aromatase activity increases, further converting available testosterone to estrogen and creating a self-reinforcing cycle of hormonal imbalance. Breaking this cycle requires addressing both the hormonal and metabolic components — which is why combining TRT with metabolic support produces better outcomes than either alone.
03
Hypothalamic-Pituitary-Gonadal Axis Disruption
The HPG axis is the signaling cascade controlling testosterone production: the hypothalamus signals the pituitary, which signals the testes. Chronic stress (elevated cortisol), poor sleep, obesity, and inflammation all disrupt this cascade at different points — suppressing the signal that drives testosterone synthesis. This is why "lifestyle changes" theoretically should help but often can't fully restore optimal T levels once the axis is disrupted.
04
SHBG and Free Testosterone
Sex hormone binding globulin (SHBG) binds testosterone in the bloodstream, making it unavailable to cells. A man with "normal" total testosterone but high SHBG may have very low free testosterone — the biologically active fraction. This is why a comprehensive hormone panel (total T, free T, SHBG, LH, FSH, estradiol) is essential to understanding the full picture — and why treating total T alone misses critical information.
05
Cardiovascular & Metabolic Implications
Low testosterone is an independent risk factor for metabolic syndrome, insulin resistance, cardiovascular disease, and all-cause mortality. The association is strong enough that many endocrinologists now consider testosterone optimization a cardiovascular health intervention in hypogonadal men, not merely a quality-of-life improvement. Physician-directed TRT — properly monitored — does not increase cardiovascular risk and may reduce it in appropriately selected patients.
06
The "Low Normal" Problem
Standard lab ranges flag testosterone as "low" only when it falls below 300 ng/dL. But many men experience significant symptoms at 350–450 ng/dL — levels technically within range but physiologically suboptimal. Dr. Cordova takes a symptom-informed approach: if your labs are in the low-normal range and you have classic symptoms, a therapeutic trial of optimization is often the most informative diagnostic and treatment step available.

TRT Is Not What You Think It Is

Testosterone replacement therapy has suffered from decades of association with performance enhancement and steroid abuse. Physician-directed TRT is categorically different. The goal is physiological restoration — raising testosterone to the upper-normal range appropriate for the patient's age, not to supraphysiological levels. Done correctly, it is a standard of care intervention for hypogonadism with a well-established safety and efficacy profile.

The evidence base is extensive. Systematic reviews and meta-analyses consistently demonstrate that TRT in hypogonadal men improves body composition (reduced fat mass, increased lean mass), energy, libido, mood, cognitive function, insulin sensitivity, and bone density. These are not marginal quality-of-life improvements — for men with significant testosterone deficiency, they can be life-changing.

Viva's TRT program is designed around ongoing physician oversight. We don't send medication and disappear. Dr. Cordova monitors labs at appropriate intervals, adjusts dosing as needed, and watches for the hormonal imbalances (hematocrit, estradiol, fertility markers) that require attention in any TRT protocol. This is medicine, not a supplement subscription.

Starting Your TRT Program

Step 1
Physician Consultation
An honest conversation about your symptoms, history, and goals. Dr. Cordova reviews previous labs if available, assesses your symptom profile, and explains what TRT can and cannot do. No pressure — no one-size-fits-all approach.
Step 2
Bloodwork
Comprehensive hormone panel: total testosterone, free testosterone, SHBG, estradiol, LH, FSH — plus a metabolic panel and CBC. We need the full picture before designing your protocol, not just a single testosterone number.
Step 3
Protocol Design & Initiation
Based on your labs and goals, Dr. Cordova designs your specific protocol — medication, dose, and frequency. TRT works through consistent application; you'll understand exactly what you're taking, why, and what to expect.
Step 4
Monitoring & Optimization
Monthly check-ins with lab monitoring at appropriate intervals. Most patients feel meaningful changes in energy and mood at 4–6 weeks. Body composition improvements develop over 3–6 months. Dr. Cordova adjusts the protocol as your body responds.

"The men who come in for TRT consultations are usually not the guys who are trying to get an edge. They're the guys who've been dragging for years, who feel like they've lost something — their drive, their focus, their physical capacity. In almost every case, the labs confirm exactly what they're describing. Restoring testosterone to an optimal level doesn't make them superhuman. It makes them themselves again."

TRT FAQ

The combination of symptoms (fatigue, reduced drive, body composition changes, cognitive slowing) and bloodwork (total T, free T, SHBG) establishes the diagnosis. If you have 3 or more classic symptoms, bloodwork is the logical next step. We can coordinate your lab work and physician review in a single consultation visit.
Physician-directed TRT at physiological replacement doses has an excellent safety profile in properly screened patients. The key variables are appropriate patient selection (ruling out contraindications including certain prostate conditions), appropriate dosing (restoration, not supraphysiological), and regular monitoring of hematocrit, PSA, and estradiol. With physician supervision, TRT is safe for long-term use in most hypogonadal men.
Exogenous testosterone suppresses the HPG axis signaling that drives sperm production, which can significantly reduce fertility. If fertility preservation is a concern, this is a critical conversation to have before starting TRT. There are protocols (including alternative medications) that can support testosterone optimization while preserving fertility — Dr. Cordova will discuss this in detail at your consultation.
Energy and mood improvements typically emerge within 4–6 weeks for most patients. Libido improvements often follow. Body composition changes (fat loss, muscle gain) develop over 3–6 months of consistent therapy. Bone density improvements take 12+ months to measure. Most patients describe the early weeks as a "fog lifting" — a gradual return of energy and motivation that becomes increasingly obvious.
If TRT is discontinued without a transition protocol, testosterone levels return to pre-treatment baseline — and symptoms return. The HPG axis may take weeks to months to resume normal signaling after exogenous testosterone suppression. We design stopping protocols when needed and discuss this honestly at initiation so patients understand the commitment involved before starting.
