What Are HGH (Human Growth Hormone) Injections

Self Administer Human Growth Hormone Injections

HGH injections are recombinant (or synthetic), bio-identical replications of the growth hormone that the body’s pituitary gland naturally produces. Human growth hormone (HGH) is a 191 amino acid sequence, single-chain, large protein, polypeptide molecule. It is very specific in its size and shape.

The manufacturing process of HGH is very specific. It is created in very carefully controlled laboratories within the USA. The solution is very sensitive to light and movement; hence, making it necessary to treat it with the utmost of care.

Also called somatropin, HGH injections come in two different delivery methods depending upon the brand. Some brands of HGH injections will be offered in both delivery methods; by needles and syringes and by pens. You and your doctor will decide which way is best for your treatment.

Needle and syringes:

Some brands of HGH will be prescribed to be injected vial needle and syringes. The patient must reconstitute (or mix) a vial of lyophilized powder with a vial of bacteriostatic water. Specific instructions will be given to patients regarding how to properly dilute the medication in the sterile water. The vials of medications will need refrigeration after they are mixed. They will only remain stable for a short while.


Some brands of HGH will be prescribed to be injected in convenient, easy and safe to use pens. Different pens will have varying shapes and ways to use them. They will also have different dosage options. Patients will be taught specifically how to use their devices by our experts once they have them.

Facts About HGH Injections

HGH pens are the most popular way to deliver HGH injections by most clinics. They are simple, easy and convenient to use. Some come with needle guards to hide the needles from view for those who are not too comfortable with the idea of self administering a shot to themselves.

It is important to become familiar with any kind of pen that you are prescribed. They are similar in that they are easy to learn and easy to use; however, they are also very different in what they look like and how they work. Your clinical advisor can help you with everything you need to become completely comfortable with your HGH injection device.
