Growth hormone is a prescription medicine everywhere it is regulated. What changes from country to country is which conditions it may be prescribed for, how strictly off-label use is policed, and how people feel about using it for aging. In the United States, distributing HGH for anything other than an approved medical condition is a federal crime. In Mexico, licensed physicians can prescribe it for adult deficiency after testing. In sport, it is banned worldwide.
This guide sets out the rules that can be checked, country by country, and what they mean if you are considering HGH therapy in Mexico.
What is HGH approved for?
For replacing growth hormone that the body no longer makes. Regulators approve it for children with growth failure and for adults with a confirmed deficiency, not for healthy aging.
Natural growth hormone output falls with age. In one study of healthy men, each decade of age reduced daily GH production by about 14%. That decline is normal and, on its own, is not a disease. Adult growth hormone deficiency is a diagnosis made with blood tests, and the Endocrine Society guideline calls for proper screening, IGF-1 monitoring and individualized dosing before and during treatment.
The products themselves are the same brands worldwide. Omnitrope, Norditropin, Genotropin, Saizen and Humatrope are all somatropin, growth hormone made by recombinant DNA technology. See the HGH brands we supply.
Is HGH legal in the United States?
Only with a prescription for an approved medical condition. US federal law, 21 U.S.C. § 333(e), makes it a crime to distribute or possess with intent to distribute human growth hormone for any use in humans other than the treatment of a disease or other recognized medical condition authorized by the Department of Health and Human Services and prescribed by a physician. The penalty is up to 5 years in prison, and up to 10 years if the offense involves a person under 18.
This is why US anti-aging clinics cannot legally prescribe HGH for aging, low energy or body composition alone, and why many Americans look across the border.
Is HGH legal in Europe?
Yes, as a prescription medicine for the conditions listed in each product’s marketing authorization. The European Medicines Agency authorized Omnitrope, a biosimilar of Genotropin, on 12 April 2006. Its approved uses are growth failure in children (growth hormone deficiency, chronic kidney disease, Turner syndrome, children born small for gestational age), Prader-Willi syndrome, and replacement therapy in adults with pronounced growth hormone deficiency.
Prescribing outside those uses is a matter for the individual physician under national rules, and anti-aging is not one of the approved indications.
Is HGH legal in Mexico?
Yes. Growth hormone is a prescription medicine in Mexico, regulated by COFEPRIS, the federal health authority. It is legal to obtain it with a prescription from a licensed Mexican physician, and that is how HGH Vallarta works: evaluation, bloodwork, then a prescription when a deficiency is confirmed. Read how the HGH prescription process works.
What makes Mexico different is not looser medicine but access. Licensed physicians here can diagnose and treat adult growth hormone deficiency, and the same pharmacy brands cost a fraction of US list prices. Current figures are on our HGH cost in Mexico page.
If you plan to carry medication home, bring your prescription and a signed doctor’s note, and check the current customs rules for your country before you fly. Our traveling tips page explains what to pack and what to expect.
Is HGH allowed in sport?
No. The World Anti-Doping Agency prohibits growth hormone at all times, in and out of competition. Section S2.2.3 of the Prohibited List covers growth hormone, its analogues and fragments, and section S2.2.4 covers releasing factors such as sermorelin, CJC-1295 and ipamorelin.
An athlete with a genuine deficiency must obtain a Therapeutic Use Exemption before treatment. Without one, a positive test is an anti-doping violation regardless of the prescription.
Why do attitudes toward HGH differ so much?
Because the same medicine sits at the meeting point of two ideas: treating a deficiency, which every regulator accepts, and slowing aging, which none of them has approved.
Where the law is strict, as in the United States, the public conversation is dominated by doping scandals and black-market risk. Where licensed physicians can treat adult deficiency openly, as in Mexico, patients talk about energy, sleep, body composition and lab results instead. The medicine is the same. The framing is what changes.
What stays the same everywhere
- A prescription from a licensed physician
- Blood tests before treatment to confirm the deficiency
- IGF-1 and safety monitoring during treatment
- Authentic, pharmacy-dispensed brands, not online powders
- No use in competitive sport without a Therapeutic Use Exemption
These are the standards in the Endocrine Society guideline, and they are the standards at HGH Vallarta. Prescriptions are written by Dr. Roberto Gutierrez Meza and Dr. Adrian Eduardo Cuenca Bravo, and every patient follows our HGH follow-up schedule after starting treatment.
HGH laws around the world: FAQ
Is HGH legal in the United States?
Yes, with a prescription for an approved medical condition such as growth hormone deficiency. US federal law makes it a crime to distribute HGH for any other use, including anti-aging or bodybuilding, with penalties of up to 5 years in prison. A doctor cannot legally prescribe it for those purposes.
Is HGH legal in Mexico?
Yes. Growth hormone is a prescription medicine in Mexico, regulated by COFEPRIS. It is legal to obtain it with a prescription from a licensed physician, which is how HGH Vallarta works. Read more on our page about the legality of HGH therapy in Mexico.
Can I use HGH if I compete in sport?
No. The World Anti-Doping Agency lists growth hormone, its analogues and releasing factors under section S2 of the Prohibited List, banned at all times, in and out of competition. Athletes with a genuine deficiency must apply for a Therapeutic Use Exemption before treatment.
Why do countries treat HGH so differently?
Every regulator agrees on one thing: growth hormone is a prescription medicine for a confirmed deficiency. The difference is how far they go beyond that. Most approve only specific conditions. Mexico allows licensed physicians to prescribe for adult deficiency after testing, which is why many international patients are treated here.
