Human growth hormone HGH therapy is a prescription treatment for adults with a diagnosed deficiency. Learn how it works, who qualifies, costs, and risks.
Human growth hormone (HGH) therapy is a prescription treatment that delivers synthetic growth hormone, called somatropin, to people whose pituitary gland does not produce enough of it. In the United States, it is FDA-approved only for specific diagnosed conditions, not for general anti-aging, weight loss, or athletic performance. A licensed physician must confirm a deficiency with lab testing before treatment is appropriate.
What Human Growth Hormone Therapy Actually Is
Growth hormone is made by the pituitary gland. It drives growth in childhood and helps regulate body composition, muscle mass, bone density, and metabolism in adults. When production falls because of disease, surgery, radiation, or a congenital cause, the result is a growth hormone deficiency (GHD).
Modern human growth hormone hgh therapy uses recombinant DNA technology to manufacture somatropin that is biologically identical to the hormone the body makes. It is given as a subcutaneous injection, often once daily, and the dose is adjusted based on blood levels of IGF-1, a hormone produced in response to growth hormone.
Who Qualifies for HGH Therapy
Qualification is based on a documented diagnosis, not on symptoms alone. Doctors usually order stimulation testing — the insulin tolerance test, glucagon stimulation test, or macimorelin — along with IGF-1 measurements before writing a prescription.
| Condition | Typical Patient | Notes |
|---|---|---|
| Pediatric GHD | Children with confirmed deficiency | Improves height velocity |
| Adult GHD | Adults with confirmed deficiency | Improves lean mass and bone density |
| Turner syndrome | Girls with short stature | Approved to support height |
| Prader-Willi syndrome | Children | Requires close monitoring for breathing problems |
| Chronic kidney disease | Children with growth failure | Used before transplant |
| HIV wasting or lipodystrophy | Adults | Helps with weight and fat distribution |
Adults who were treated as children often need retesting after growth is complete, because not everyone who needed therapy in childhood continues to need it later. Treating adults who have normal growth hormone levels is considered off-label, and major endocrine guidelines do not recommend it.
What Treatment Looks Like Day to Day
Most regimens involve a small nightly injection into the abdomen, thigh, or upper arm using a pen device or syringe. Many patients ask about the best time to take hgh; clinicians often suggest bedtime because the body releases growth hormone naturally during deep sleep, but consistency matters more than perfect timing. Brand-name products include Humatrope, Genotropin, Norditropin, and Omnitrope.
Follow-up usually includes IGF-1 testing every few months plus blood sugar, thyroid, and lipid checks. Doses are raised slowly to limit side effects.
Common side effects
- Fluid retention, with swelling in the hands, feet, or face
- Joint and muscle aches
- Carpal tunnel-type symptoms
- Injection-site redness or bruising
- Headache
Less common but serious risks
- Rising blood sugar or new insulin resistance
- Benign intracranial hypertension, or pressure around the brain
- Worsening sleep apnea
- In children, hip problems and progression of scoliosis
People with active cancer, diabetic retinopathy, or an acute critical illness should not use growth hormone. Review your history with a healthcare professional before starting any injectable therapy.
Cost, Access, and the Gray Market
Somatropin is a prescription-only drug in the US, and distributing it for non-approved uses is illegal. Brand-name pens commonly cost $1,000 to $3,000 or more per month without insurance, though coverage is often possible when a deficiency is documented.
Websites that sell "research grade" HGH or freeze-dried peptide powders without a prescription operate outside FDA rules. Products bought this way can be mislabeled, contaminated, or contain no active ingredient at all.
Supplies and Related Compounds People Research
People who research injectables often land on the same questions about handling and storage. Reconstituting a powder requires bacteriostatic water, and users frequently wonder whether bacteriostatic water walgreens pharmacies stock it — most locations keep it behind the counter and may require a prescription or pharmacist approval.
Knowing how long is bac water good for in the fridge matters for safety: bacteriostatic water is generally discarded 28 days after the first puncture, even when refrigerated. Anyone searching for the best bac water for peptides should look for a clear lot number, sterile filtration, and 0.9% benzyl alcohol as the preservative.
Other injectables that appear alongside HGH in search results include AOD-9604, MOTS-c, and compounded Lipo-C blends. None of these are FDA-approved for weight loss, and questions like aod 9604 vs mots-c usually compare research compounds rather than proven treatments.
| Product | Category | FDA Status |
|---|---|---|
| Somatropin (HGH) | Recombinant human hormone | Approved for specific diagnoses |
| AOD-9604 | Fragment of HGH (amino acids 176-191) | Not approved |
| MOTS-c | Mitochondrial-derived peptide | Not approved |
| Lipo-C | Compounded injection with methionine, inositol, and choline | Not an FDA-approved drug |
The Bottom Line
Human growth hormone therapy is legitimate medicine for people with a confirmed deficiency and a short list of other diagnoses. It is not a general wellness product, and its risks — blood sugar changes, fluid retention, joint pain — increase with dose.
If you suspect a growth hormone deficiency, start with an endocrinologist or primary care doctor instead of an online seller. Ask about testing, insurance coverage, and monitoring before you commit to treatment.
Frequently Asked Questions
Is HGH therapy legal in the United States?
Yes, when a licensed physician prescribes somatropin for an FDA-approved diagnosis such as adult or pediatric growth hormone deficiency. It is illegal to distribute HGH for non-medical uses like bodybuilding or anti-aging, and buying it from an overseas or "research" website without a prescription is not legal.
Can HGH therapy reverse aging or burn fat?
No. Studies show small changes in body composition, such as reduced fat mass and increased lean mass, but there is no reliable evidence that growth hormone reverses aging, and side effects like fluid retention and elevated blood sugar are common. Major medical organizations do not recommend growth hormone for anti-aging.
How much does HGH therapy cost per month?
Without insurance, brand-name somatropin usually runs about $1,000 to $3,000 or more per month, depending on the dose and product. Insurance may cover it when a growth hormone deficiency is documented with lab testing, and compounded versions cost less but still require a prescription.
