HGH Pens vs. HGH Injections: What’s the Difference?

Last updated on April 13th, 2025 at 03:59 pm

In this article, we’ll take a closer look at the differences between HGH pens and HGH injections, focusing on the fact that the choice depends on personal preference and lifestyle. In general, we can say that those looking for a hassle-free human growth hormone therapy experience should consider checking out human growth hormone pens from trusted sources.

The pituitary gland produces human growth hormone (HGH) and regulates metabolism and growth. Synthetic HGH, which can be obtained via prescription, treats conditions such as muscle-wasting diseases in adults and short stature in children. However, it has not been FDA-approved for performance enhancement or anti-aging protocols.

What is an HGH Injection?

In continuation of the theme we just touched upon, if the body does not produce enough human growth hormone, an individual may need to have growth hormone injections. To this end, the most common treatment in both children and adults is lab-developed injections for growth hormone therapy, with doses taken daily or several times weekly, depending on the severity of the deficiency. Growth hormone has been developed to imitate natural growth hormone behavior in the body. It is ultimately prescribed by a doctor and self-administered or given by said doctor.

There are certain features doctors base this treatment on, such as:

• Age

• Extent of condition

• Overall health and medical history

• Treatment expectations

• Tolerance for specific treatment

• Patient preference

Some things to consider when deciding if human growth hormone injections are right for you or a loved one include:

• Precise Dosage Control—Small changes in human growth hormone levels affect the body, and too little or too much growth hormone can lead to significant growth problems. Too little growth hormone is one of the primary causes of conditions such as dwarfism and short stature.

• More Preparation Time—Human growth hormone injections, at least for children, should be given at night, preferably within an hour of sleep, and should be given consistently within that time frame (for example, between 9 and 10 p.m. every night). Put succinctly, they require more preparation time than other applications, such as pens.

• Less Convenient for Travel—Disposable pens have been assessed as significantly easier to use by patients taking human growth hormone treatment, notably when traveling.

• Potential for Injection Errors—Possible side effects of injection errors include joint discomfort, muscle aches, headaches, and swelling of the hands and feet.

What is an HGH Pen?

The perceived ease-of-use and functionality of a reusable pen injector incorporates several advanced features, supposedly improving acceptability and the aforementioned ease-of-use in comparison with the traditional needle-and-syringe injection. Most of these pen devices comprise a multi-dose injection mechanism constructed of aluminum, coupled with a multi-use cartridge system, a full cartridge-viewing window, a single-digit dose display window with a rotating dose-selection knob, and an injection button.

Some benefits of using human growth hormone pens include:

• Pre-Measured Doses—Some pens, such as FlexPro (developed by Novo Nordisk A/S), deliver Norditropin, a multi-dose, premixed, preloaded disposable device that requires relatively less force to inject and does not require refrigeration after initial use.

• Easy and Quick Administration—Products like Pfizer’s GENOTROPIN pen have been designed to make daily treatment easy for patients to administer.

• More Comfortable, Less Painful – Reliability, ease-of-use, lack of pain during injection, safety in use, storage, and number of steps in preparation before use, during use, and after are considered to be the five most desirable attributes of a pen administration device.

• Ideal for Travel—When traveling with a growth hormone pen, it is important to keep it cool and store it somewhere safe.

• Lower Risk of Errors – In general, devices that require fewer steps may lead to reductions in dosing errors.

How to Choose an HGH Injection

A doctor typically discusses the various types of human growth hormone injections or pre-filled injectable pens with the patient, who then determines which prescription is best for his or her needs and lifestyle. Regardless of the type of growth hormone treatment chosen, patients are given an injection kit and instructed by the practitioner on how to use and care for it.

Prescription growth hormone injections are available in several forms, including:

• An injectable liquid

• A pre-filled injectable pen

• A powder that is reconstituted into an injectable liquid (this is not nearly as common as the two forms we covered in this article)

Conclusion

Human growth hormone is administered as an injection, not an oral pill, for growth hormone deficiency. These injections utilize either traditional needles and syringes or convenient pen devices such as Norditropin FlexPro to deliver the hormone. Human growth hormone pens like the aforementioned FlexPro are preloaded, prefilled devices that simplify the injection process. Some pens are available in multi-dose, disposable, and premixed variants.
