What Is Saizen?

Saizen, also called or Somatropin (rDNA origin) is a human growth hormone (HGH) injectable medication created by the manufacturing company Merck Serono. It is identical to the growth hormone (GH) that is already being produced in the human body. It is a large protein molecule and its chemical makeup includes a 191 amino acid sequence.

Saizen medication is very sensitive to light, temperature and movement. It must be created in a very controlled atmosphere and handled with the utmost of care. It will be injected just under the skin, but never injected directly into a vein or muscle.  

Saizen is a controlled substance. That means that the government makes sure that it is only distributed and sold by authorized professionals and only used by those who have gotten a prescription for it. Although it is a potent medication, with the right testing, prescription and medical supervision, Saizen can be very safe and make incredible change.

Saizen is produced in the body by the pituitary gland. This is a small gland that is located at the base of the hypothalamus in the brain. When a person ages, the pituitary does not make enough growth hormone and symptoms of aging will begin. This is when Saizen can be prescribed and used as an exact replica of what the body knows. In other words, when using injectable Saizen through injection, the body will balance its hormones and the person will look and feel years younger than their biological age.


Saizen is indicated for use with those who have been diagnosed with a growth hormone deficiency. It is for both men and women who are over 30. A simple blood test will tell a doctor if a person is GH deficient and that is when they can also determine the dosage of Saizen that will help a person get their quality of life back. By replacing lost growth hormones with this highly regarded medication, a person can rid of the symptoms they had when they first called us. Our success rate using Saizen has been very high.

Saizen is indicated for the removal of symptoms such as lethargy, forgetfulness, depression, body pain, weight gain, muscle loss, lack of stamina, vigor and vitality, lack of sexual desire, erectile dysfunction, difficulty with healing and getting sick often. There are many more symptoms of low GH levels that Saizen can end and they are listed in full below.

Forms Available:

Saizen is available in four different pen types:

  • easypod ® with click.easy ® – 8.8 mg
  • cool.click ® – 5 mg and 8.8 mg
  • one.click ® – per doctor’s prescription

Saizen can also be taken via traditional needles and syringes. For the three different pens that are offered for this medication, detailed instructions will be given to patients about the kind of device they will be using. Our clinical advisors not only teach patients how to use their Saizen devices, but they also will help one on one over the phone with medication preparation and administration. 

The patient and the doctor will determine together which device will be best for the client. The determination will be based on several different factors: the patient’s age, how he or she can tolerate needles, the client’s weight, how he or she bruises from injections and other medical conditions.

Here are the different pens that are offered to deliver the human growth hormone Saizen:

Saizen easypod

Saizen easypod ® – This device is a truly innovative way of delivering medication. It is electronic and automatically inserts its needle into the skin to deliver a preset dosage of medication. This pen also has a dose calendar. This will keep track of when patients give themselves a dose of Saizen.

The click.easy ® cartridge is intended for use with this pen. It comes in an 8.8 mg dose. It is self contained and already holds the preset prescribed dosage of medication in it. The solution is already reconstituted and ready for quick and easy delivery into the body. After it is emptied, it is intended to be disposable.

For those who are apprehensive about needles, this is a great device. It hides the needle from view before, during and after injection. The pen will show how much medication is left in it and will also show when it is time to change the cartridge.

Lastly, the pen offers patients the ability to set and control how deeply the needle goes into the skin, how fast the injection happens and how fast the needle goes into the skin. The doctor will set the device initially for the patient. Then, the patient’s advisor can show how to adjust what are called the “comfort settings.”

The cool.click ® Saizen pen

The cool.click ® – 5 mg and 8.8 mg Saizen pen is for those who do not want to use a needle during therapy. This is a needle free delivery option.

The Saizen medication is dispersed through the skin by a spring mechanism in the pen. This device has a nozzle and digital display to read the dosage amount. As with all of the pens, a clinical advisor will explain in detail exactly how to use this pen.

The one.click ® Saizen pen

The one.click ® Saizen pen is a compact and portable device. It is great for one the go usage. It is an auto-injector pen. Prior to using the pen, patients must reconstitute the medication. This mixing of the solution can be done in just three easy steps and the clinical advisor will show the patient exactly how to do it.

Saizen can also be taken with traditional needles and syringes. This is a viable option for those who choose it.
