How to Get an HGH Prescription

Written by Author - Authors Medical experts of the National HRT Clinic - October 16, 2015

Getting an HGH prescription requires a proper medical evaluation, blood testing, and a diagnosis of growth hormone deficiency. Unlike some medications, you can’t simply ask your doctor for HGH and expect a prescription. There’s a specific process designed to ensure HGH therapy is safe and appropriate for you. This guide walks you through exactly what to expect and how to get started if you think you might have low growth hormone.

HGH Prescription

Who Qualifies for an HGH Prescription?

Not everyone qualifies for an HGH prescription. Growth hormone therapy is prescribed for people with documented growth hormone deficiency—meaning blood tests show low IGF-1 levels and symptoms consistent with low GH. Here’s who typically qualifies:

  • Adults with adult-onset GH deficiency: People whose pituitary glands produce insufficient growth hormone due to aging, pituitary disease, previous head trauma, or other medical conditions.
  • People with symptoms of low GH: Including unexplained weight gain, loss of muscle mass despite exercise, chronic fatigue, poor sleep quality, thinning skin, bone loss, or sexual dysfunction.
  • People with documented low IGF-1 levels: Blood work is the key. If your IGF-1 is below the normal range for your age and sex, you may be a candidate for HGH therapy.
  • People in good overall health: Certain health conditions (active cancer treatment, severe diabetic retinopathy, severe illness) make HGH therapy inadvisable. Your doctor will screen for these issues.

Your doctor determines if you qualify based on your specific situation. It’s not about wanting to feel better or look younger—it’s about having objectively low growth hormone confirmed through blood work.

The Prescription Process

Medical Evaluation

Your first step is a consultation with a National HRT doctor. This can be done in-person or via telehealth. During this evaluation, our doctor will:

  • Ask about your symptoms: fatigue, weight changes, muscle loss, sleep problems, sexual function, skin changes, mood, and other signs of low growth hormone.
  • Review your medical history: past illnesses, surgeries, head injuries, medications, family history, and any pituitary or endocrine issues.
  • Discuss your goals: What specific improvements are you hoping for? This helps your doctor determine if HGH therapy is likely to help you.
  • Perform a basic physical exam or vital signs check: If in-person, your doctor may check blood pressure and perform a brief physical. For telehealth, they may ask you to report vital signs.
  • Assess your candidacy: Based on your symptoms and medical history, our doctor determines if HGH testing and therapy make sense for you.
  • This initial consultation usually takes 30 minutes to an hour and is completely free.

Blood Work (IGF-1 Testing)

After your consultation, our doctor will send you for blood testing. The key test is IGF-1 (insulin-like growth factor 1), which reflects your body’s growth hormone production and action. Unlike growth hormone itself (which fluctuates throughout the day), IGF-1 is stable, making it a reliable marker of your GH status.

We schedule your blood work at one of our partner laboratories close to your location. You can usually get blood drawn within a few days. You’ll receive instructions on whether to fast beforehand (usually yes, for consistency).

You may also be tested for:

  • Other hormones: testosterone, thyroid hormones (TSH, Free T4), cortisol.
  • Metabolic markers: glucose, lipid panel, liver and kidney function.
  • Results typically come back within 5-7 business days.

Diagnosis Criteria

Your doctor uses specific criteria to determine if you have growth hormone deficiency:

  • Low IGF-1 level: Your IGF-1 must be below the normal range for your age and sex. The normal range varies by age—younger people have higher normal IGF-1 than older people. Your lab results will show what’s normal for your age.
  • Symptoms consistent with low GH: You need to have symptoms that match growth hormone deficiency—fatigue, weight gain, muscle loss, low libido, poor sleep, thin skin, etc. Without symptoms, even low IGF-1 may not justify treatment.
  • No contraindications: Your doctor will ensure you don’t have conditions that make HGH therapy inadvisable, such as active cancer, diabetic retinopathy, or severe chronic illness.

If you meet these criteria, you’re a candidate for HGH prescription.

Getting Your Prescription

If you qualify, our doctor prescribes HGH specifying:

  • Brand: Norditropin, Genotropin, Omnitrope, Humatrope, Saizen, or another FDA-approved brand.
  • Dose: Usually starting at a low dose (around 0.3-0.5 IU per kg of body weight per day) and adjusted based on how you respond.
  • Frequency: Typically once daily, usually injected in the evening.
  • Quantity: Usually a 30-day supply to match your follow-up appointment schedule.
  • The prescription is sent directly to a licensed pharmacy. FDA-approved HGH is shipped to your home within a few business days.

Can You Get HGH Prescribed Online?

Yes. Many qualified HRT clinics now offer telemedicine services, allowing you to get an HGH evaluation and prescription entirely online. The process is the same:

  1. You have a video consultation with a National HRT doctor.
  2. We schedule your blood work at a partner laboratory near you.
  3. Our doctor reviews your results and determines if you qualify.
  4. If you qualify, the prescription is sent directly to a licensed pharmacy.
  5. FDA-approved HGH is shipped to your home.

Online HGH prescriptions are completely legal when provided by a licensed doctor. The key is working with a real medical clinic like National HRT, not an unregulated online retailer.

Why You Cannot Buy HGH Without a Prescription

HGH is a prescription-only medication in the United States for important reasons:

  • Medical supervision is essential: Growth hormone affects many body systems. Your doctor needs to monitor you with regular blood work and appointments to ensure treatment is safe and working.
  • Proper dosing requires testing: Without knowing your IGF-1 level, there’s no way to determine the right dose. Too little HGH doesn’t work; too much increases side effect risk.
  • Counterfeits are rampant: Unregulated HGH online is often counterfeit, contaminated, or completely fake. A prescription from a licensed doctor and fill at a licensed pharmacy guarantees you’re getting real, pharmaceutical-grade HGH.
  • Quality control: FDA-approved HGH from licensed pharmacies is manufactured under strict quality controls. Illegal online sources have no quality oversight.
  • Safety screening: Your doctor checks for conditions that make HGH therapy unsafe. Without this screening, you could harm yourself.
  • Legal protection: Buying or selling HGH without a prescription is illegal. Working with a licensed clinic protects you legally.
  • The prescription requirement exists to protect your health and safety.

FAQs

Can any doctor prescribe HGH?

Technically, any licensed doctor can prescribe HGH. However, not all doctors are qualified to prescribe it effectively. You want a doctor who specializes in hormone replacement therapy or endocrinology—someone experienced with HGH therapy, knowledgeable about dosing, and committed to monitoring you properly. A general practitioner may be willing to prescribe HGH, but may not manage your care as effectively as a specialist would. Ask potential doctors about their experience with HGH therapy before committing to treatment.

How long does it take to get an HGH prescription?

From your initial consultation to receiving HGH typically takes 1-2 weeks. The initial consultation can often be scheduled within 2-3 days. Blood work is arranged at a partner lab and takes 5-7 days for results. Once our doctor confirms your diagnosis, the prescription is sent directly to a licensed pharmacy, which fills and ships within 2-3 business days. Total time is usually 10-14 days from start to finish.

Can I get HGH prescribed for anti-aging?

HGH is FDA-approved for treating documented growth hormone deficiency, not for general anti-aging purposes. However, if you have objectively low IGF-1 levels and symptoms consistent with GH deficiency—which are common as you age—then HGH therapy is medically appropriate and can produce anti-aging benefits as a consequence of restoring hormone levels. Your doctor will determine whether your low growth hormone is significant enough to warrant treatment, regardless of whether you’re seeking anti-aging benefits or symptom relief.
