Finding the right TRT doctor can make or break your testosterone replacement therapy journey. I've been on TRT for over 34 years, and I've spoken with thousands of men who either thrived because they found a knowledgeable physician — or suffered because they didn't. The good news: in 2025, men have more options than ever, including telemedicine clinics that can treat you from anywhere in the U.S.
The bad news? Not all doctors are created equal when it comes to hormone optimization. Many are undertrained, overly cautious, or simply unfamiliar with modern TRT protocols. This guide will help you find one who isn't. If you're ready to search now, use our

Can Your Primary Care Doctor Prescribe TRT?
Yes — and many do. Primary care physicians and urologists can legally prescribe testosterone replacement therapy, and a growing number are comfortable doing so as awareness of hypogonadism (low testosterone) has increased.However, there's a significant gap between a doctor who can prescribe testosterone and one who truly understands how to manage TRT well. Common shortcomings with general practitioners include:
Prescribing doses that are too low to be therapeutic ("normal" by lab standards but still symptomatic)
Refusing to prescribe HCG alongside testosterone to preserve testicular function and fertility
Not monitoring estradiol, hematocrit, or other critical markers that change on TRT
Defaulting to testosterone gels when injections are often more effective and cost-efficient
Pulling patients off TRT at the first sign of elevated PSA or hematocrit without proper management
"Educated patients get better care. If your doctor can't answer basic questions about managing estradiol or hematocrit on TRT, keep looking." — Nelson Vergel

If your current doctor is willing to learn alongside you and order the right labs, that relationship can work. But if they're resistant to HCG, won't discuss anastrozole, or insist on keeping your testosterone at the low end of "normal," a specialist or TRT-focused clinic will serve you better.
What Makes a Good TRT Doctor?
A knowledgeable TRT physician will approach your care comprehensively — not just prescribe testosterone and send you on your way. Here's what distinguishes them:They Monitor the Right Labs
TRT affects multiple systems in the body. A good doctor orders and interprets a complete panel, including:- Total and free testosterone (trough and peak levels)
- Estradiol (sensitive assay, not standard)
- Hematocrit and hemoglobin (elevated hematocrit is the most common TRT side effect)
- PSA (prostate-specific antigen)
- LH and FSH (especially if fertility is a concern)
- Comprehensive metabolic panel (liver and kidney function)
- Lipid panel
- SHBG (sex hormone-binding globulin)
They Understand HCG and Fertility
Testosterone alone suppresses your body's natural production of LH and FSH, which causes testicular atrophy and infertility. A well-trained TRT doctor knows how to co-prescribe HCG — or alternatives like enclomiphene — to maintain testicular function, preserve fertility, and improve how patients feel on therapy.They Manage Side Effects Proactively
Elevated estradiol, rising hematocrit, acne, and mood changes are manageable — but only if your doctor knows what to look for. Good TRT physicians have protocols in place and don't simply take you off testosterone when problems arise.They Work with Compounding Pharmacies
Brand-name testosterone is expensive, and not all forms or dosages are commercially available. A knowledgeable TRT doctor will have a relationship with a reputable compounding pharmacy to provide customized formulations at lower cost — including injectable testosterone cypionate, HCG, anastrozole, and more.10 Questions to Ask Any TRT Doctor or Clinic
Before committing to a doctor or clinic, ask these questions — either in your first consultation or by calling their office directly. Their answers will tell you a lot.- How many men do you currently treat for hypogonadism or TRT?
- Do you prescribe HCG alongside testosterone to preserve testicular function and fertility?
- What labs do you monitor, and how frequently?
- Do you monitor estradiol with a sensitive assay (not just a standard E2 test)?
- How do you manage elevated hematocrit — do you refer for therapeutic phlebotomy?
- Do you work with compounding pharmacies for testosterone injections and other medications?
- Do you allow home self-injection, or do I need to come in for every dose?
- What is your protocol if I want to preserve my fertility while on TRT?
- What are your fees, and what does insurance typically cover?
- How often will I need in-person visits versus telemedicine or phone check-ins?
A doctor who is well-versed in TRT will welcome these questions. One who seems annoyed or dismissive is probably not the right fit.
Red Flags to Avoid
Not all TRT practices are created equal. Watch out for these warning signs:Prescribing testosterone without baseline bloodwork
Refusing to co-prescribe HCG or discuss fertility preservation
Monitoring only total testosterone and ignoring estradiol, hematocrit, and SHBG
Insisting on gels only (often driven by manufacturer relationships, not patient outcomes)
High-pressure sales tactics for expensive add-ons at first consultation
No physician oversight — some "clinics" are run primarily by nurse practitioners with limited hormone training
Refusing to share your lab results directly with you
Best Online TRT Clinics (Telemedicine Options in 2026)
One of the biggest changes in men's healthcare since 2020 is the rise of telemedicine TRT.

For a curated list of TRT doctors by region, see: TRT Doctor Lists and More.2. Urology and Endocrinology Specialists
Urologists often have the most experience with hypogonadism and testosterone therapy. Endocrinologists vary widely — some are excellent, others are dismissive of TRT for anyone outside narrow diagnostic criteria.3. Men's Health Clinics
Dedicated men's health and hormone clinics have proliferated in recent years. Quality varies significantly. Use the questions above to vet any clinic before your first paid appointment.4. Anti-Aging and Functional Medicine Physicians
Many functional medicine and anti-aging physicians have deep expertise in hormone optimization and are often more open to comprehensive TRT protocols than conventional doctors. Look for board certification and verify their specific experience with TRT.What to Expect at Your First TRT Appointment
Walking into your first TRT consultation prepared will dramatically improve the quality of care you receive. Here's what typically happens — and what you should bring:What the Doctor Should Do
Take a complete medical history, including symptoms of low T (fatigue, low libido, mood changes, poor recovery, brain fog)Order baseline bloodwork before prescribing anything
Discuss treatment options including injection frequency, delivery method, and adjunctive therapies
Explain the risks and benefits honestly
Establish a monitoring plan for follow-up labs
What You Should Bring
Any previous lab results, especially testosterone panelsA list of current medications and supplements
Your list of symptoms and how long you've experienced them
The 10 questions listed above
A note about fertility goals, if relevant
Tip: If you've had labs done through DiscountedLabs.com or another direct-to-consumer service, bring those results. They can save time and give your new doctor valuable baseline data.
Essential Lab Tests Before Starting TRT
A responsible TRT doctor will order these labs before prescribing. If they don't, ask for them:Total testosterone (morning draw, before 10am for accurate baseline)
Free testosterone (calculated or dialysis method)
LH and FSH (to determine if low T is primary or secondary)
Estradiol — sensitive assay (not standard E2)
SHBG (sex hormone-binding globulin)
Complete blood count including hematocrit and hemoglobin
Comprehensive metabolic panel
Lipid panel
PSA (prostate-specific antigen)
Prolactin (to rule out pituitary issues)
Thyroid panel (TSH, free T3, free T4) — thyroid dysfunction mimics low T symptoms
You can order many of these directly through DiscountedLabs.com without a doctor's visit, at significantly lower cost than going through insurance. This is a good way to arrive at your first appointment with data in hand.
Frequently Asked Questions
Can a primary care doctor prescribe testosterone?
Yes. Primary care physicians, internists, urologists, and endocrinologists can all prescribe testosterone. The key is finding one with enough experience managing TRT comprehensively — not just writing a prescription.How do I get TRT prescribed online?
Telemedicine TRT clinics like Defy Medical allow you to get diagnosed and prescribed remotely. The process typically involves an online consultation with a physician, labs drawn at a local lab center, and medications shipped to your home. Most require a telehealth visit and baseline bloodwork before prescribing.What's the difference between a TRT clinic and an endocrinologist?
Endocrinologists specialize in hormones broadly (thyroid, diabetes, adrenal, etc.) and may or may not have deep TRT expertise. TRT-focused clinics specialize exclusively in hormone optimization for men and are generally more experienced with the nuances of testosterone protocols, HCG, and side effect management.How much does TRT cost with and without insurance?
Costs vary widely. Brand-name testosterone gels can run $200–$500/month through insurance with copays. Injectable testosterone cypionate through a compounding pharmacy can cost as little as $30–$80/month. Clinic fees, lab costs, and medication costs should all be discussed upfront. Telemedicine clinics are often more transparent about total cost.Do I need to be on TRT forever once I start?
TRT suppresses your body's natural testosterone production, so stopping cold turkey causes levels to crash. However, with proper guidance — including HCG during therapy and a managed tapering protocol — some men can preserve enough natural function to discontinue. This is a conversation to have with your doctor before starting.Next Steps
Finding the right TRT doctor is one of the most important decisions you'll make on your hormone optimization journey.
