Somatropin brand names include Genotropin, Humatrope, Norditropin, Omnitrope, and Saizen. Compare FDA-approved HGH products, makers, and costs.
Somatropin brand names sold in the United States include Genotropin, Humatrope, Norditropin, Omnitrope, Saizen, Zomacton, Serostim, and Zorbtive. Somatropin is the generic name for recombinant human growth hormone (rHGH), a prescription-only injectable approved for specific growth, metabolic, and wasting conditions. Every FDA-approved brand contains the same 191-amino-acid hormone, so the real differences come down to manufacturer, delivery device, and approved indications.
What Somatropin Is and Where It Fits
Somatropin sits in the somatropin drug class of recombinant human growth hormone products. It is a lab-made copy of the 191-amino-acid hormone your pituitary gland produces, and it is given by subcutaneous injection.
Somatropin is not an anabolic steroid and is not a federally scheduled controlled substance, but it is still prescription-only. The name is pronounced "soh-muh-TROH-pin," and products are sometimes labeled "somatropin 191" because of that amino acid chain length.

Older brands such as Accretropin, Tev-Tropin, and Nutropin AQ have been discontinued in the U.S. If a price list still advertises those names as current, treat the listing with suspicion.
Is There a Generic Somatropin?
There is no classic generic somatropin in the United States. Somatropin is a biologic, and biologics are not automatically interchangeable the way small-molecule generics are.
Omnitrope was approved in 2006 as a follow-on protein product rather than a true generic. Most discussions about omnitrope vs somatropin come down to price, insurance coverage, and pen design rather than any difference in the hormone itself.
Every legally sold somatropin product in the U.S. is a brand-name biologic, so "generic somatropin" is a marketing phrase rather than a regulatory category.
All FDA-approved brands share the same amino acid sequence and are treated as therapeutically equivalent for their approved uses. What changes between them is the device, the preservative, and the concentration.
Somatropin Pens, Cartridges, and Vials
A somatropin pen is the most common delivery format in the U.S. because it simplifies daily dosing for both children and adults.
| Format | Example products | Notes |
|---|---|---|
| Pre-filled pen | Norditropin FlexPro, HumatroPen | Little to no preparation; dose dialed or fixed |
| Cartridge plus reusable pen | Omnitrope, Saizen click.easy, Genotropin | Usually lower cost per milligram |
| Single-dose vial | Zomacton, Humatrope | Requires mixing and a syringe draw |
| Multi-dose vial | Serostim, Zorbtive | Specialty indications |
Vial and ampule formats remain available for patients who reconstitute powder with bacteriostatic water and draw each dose with a syringe. Dosing itself is always individualized by body weight, indication, and IGF-1 response, and it is not determined by which brand you choose.
Non-FDA-Approved and Grey-Market Somatropin Brands
A large grey market sells somatropin under brand names that never went through FDA review. Jintropin, Ansomone, and Hygetropin are Chinese labels frequently named in that market, along with a long list of "100 IU kit" products from overseas manufacturers.
Some of these are legitimate products approved by other countries' regulators. Others, including forum names such as Driada, Hilma, and Cybergen, are not verifiable pharmaceutical products at all.
None of these products are FDA-approved for U.S. sale, and their potency, sterility, and actual hormone content are unverified.
Somatropin bodybuilding use is not an approved medical indication, and importing these products for personal use is illegal in the United States. The FDA specifically excludes human growth hormone from its personal importation policy.
What Somatropin Costs
Somatropin cost in the U.S. without insurance commonly falls between roughly $1,000 and $5,000 per month, depending on dose, product, and pharmacy. Pediatric doses are weight-based, so a growing child may need more milligrams than an adult on replacement therapy.
Insurance usually covers somatropin when the diagnosis matches an approved indication, such as growth hormone deficiency, Turner syndrome, or Prader-Willi syndrome. Most plans require prior authorization, documented lab results, and periodic re-approval.
Cash-pay patients sometimes switch products purely on price, since the hormone is considered equivalent across approved brands.
Safety and Legal Status
Somatropin is generally well tolerated when prescribed and monitored, but it is not risk-free.
- Common side effects include injection-site reactions, fluid retention, joint and muscle aches, and elevated blood sugar.
- Serious risks include increased intracranial pressure, carpal tunnel syndrome, hypothyroidism, and hip problems in children.
- Routine monitoring includes IGF-1 levels, thyroid function, blood glucose, and growth measurements.
It is a federal offense in the United States to distribute somatropin for any use other than a recognized medical purpose.
Anyone considering somatropin should work with a healthcare professional, get baseline labs, and use only pharmacy-dispensed products from a licensed U.S. source.
Frequently Asked Questions
What are the most common somatropin brand names?
The main FDA-approved somatropin brands in the U.S. are Genotropin (Pfizer), Humatrope (Eli Lilly), Norditropin (Novo Nordisk), Omnitrope (Sandoz), and Saizen (EMD Serono). Zomacton, Serostim, and Zorbtive are also approved for narrower indications. All contain the same recombinant human growth hormone.
Is there a generic form of somatropin?
No. Somatropin is a biologic, so there is no classic generic version in the United States. Omnitrope was approved in 2006 as a follow-on protein product, which is the closest thing to a generic, and all other legal products are brand-name biologics.
Are non-prescription somatropin brands like Jintropin safe?
These products are not FDA-approved for U.S. sale, so their potency, sterility, and actual hormone content are unverified. The FDA specifically excludes human growth hormone from its personal importation policy, meaning it cannot legally be brought into the country for personal use. Only pharmacy-dispensed products from a licensed U.S. source should be used.
