What is Somatropin HGH?

Written by Author - Authors Medical experts of the National HRT Clinic - November 30, 2015

The somatropin is a recombinant form of the chemical messenger in the body known as somatotropin (growth hormone). It is biologically identical in structure to this single chain polypeptide protein that is made up of 191 amino acids. Due to its molecular similarity, it is immediately identifiable to the GH receptor cells in the body upon administration, and can be put to direct use supplying the same signals for functioning as somatotropin.

Contrary to its name, growth hormone does more for the body than just assist in the process of achieving one’s ideal adult height. It continues to provide benefits to the muscles and bones every day of our lives. In fact, since it is a crucial part of the cellular regeneration process in the body, the effects of somatropin HGH are felt on a widespread basis.

Pharmaceutical companies manufacture recombinant HGH somatropin injections for use by both children and adults. The purpose of this medication is different in these groups. Children with short stature or other conditions that keep them from growing at a proper rate will use HGH therapy for help in speeding up the growth process. Adults have other reasons for use, which will be covered in the next section.

Who Can Benefit from Somatropin HGH?

There is much debate as to who can benefit from using HGH somatropin. This medication is already approved for use in adults with AIDS to prevent muscle wasting and weight loss. It is also prescribed for the treatment of short bowel syndrome, and has been used experimentally by some doctors for the treatment of Crohn’s disease, ulcerative colitis, fibromyalgia, and multiple sclerosis.

Since the production of growth hormone in the body does start to decline as people age, typically starting at some point after the age of thirty, doctors have been using this medication to treat GH decline in adults who show signs of deficiency.

What is somatropin used for in adults with this chemical shortage since they are no longer worrying about growing? Although linear growth is over by the time most people reach their early twenties, that does not mean that the muscles and bones stop their growth process.

Here are some examples of why adults can benefit from somatropin HGH:

  • A process called bone remodeling continues throughout the course of one’s life. As old bone cells die, they are absorbed, and new bone cells are needed to take their place. Since GH is responsible for stimulating the process of cellular reproduction, a deficiency means that there will often be a shortage of new bone cells required to replace those that have already been reabsorbed. This causes the bones to weaken, resulting in osteoporosis and a loss of linear height. In other words, this is why people tend to shrink in height as they age.
  • Maintenance of lean muscle mass also relies on growth hormone. GH deficiency is the reason why many adults no longer get the same results at the gym as they age. Protecting muscular integrity is crucial to ensuring that the skeletal system has the support from the muscles that it needs as we age.
  • Somatropin is important for men and women to maintain a sense of healthfulness, vitality, drive, and motivation. It keeps us focused, happy, energized, and amorous.

Once an adult starts to experience signs of a growth hormone decline, treatment with somatotropin injections can reverse the symptoms that are present.

Benefits of Somatropin HGH

The many benefits of somatropin HGH can make quite a difference in the life of a person who has been dealing with a decline in his or her body’s production of somatotropin. The adverse effects associated with the condition known as growth hormone deficiency can do more than create havoc in a person’s life. If left untreated for many years, or even decades, it can lead to social isolation, serious illness, and problems with all interpersonal relationships. That is why the benefits have been heralded as life changing by many people receiving this treatment.

What is somatropin going to do once it has been administered into the body via subcutaneous or intramuscular injection? Since its structure is molecularly identical to the GH that is produced by the somatotropic cells in the anterior area of the pituitary gland, it is going to be rapidly assimilated and put to work providing crucial signals to receptor cells in the brain, liver, bones, muscles, and throughout the body.

The will lead to the following somatropin results:

  • Increased vitality, energy, and stamina
  • Improved brain functions, cognitive skills, memory, focus, learning, and concentration
  • Stronger bones
  • Better sleep
  • Increased lean body (muscle) mass
  • Improved flexibility
  • Reduced or eliminated joint pains and stiffness
  • Enhanced immune system functions
  • Shortened recovery time from exercise, illness, or injury
  • Sharper eyesight and night vision
  • Restored libido – better sexual desire and arousal
  • Improved erectile functions
  • Reduction or cessation of symptoms associated with menopause
  • Better metabolic functions
  • Loss of excess belly fat
  • Increased collagen production resulting in firmer skin
  • Thicker hair with some possible regrowth and return of natural color
  • Stronger nails
  • Improved mood and overall outlook on life
  • Increased drive, motivation, and productivity
  • Temperature regulation
  • Lower LDL (bad) cholesterol

An adult dealing with a serious decline in GH production can expect to receive many positive benefits when his or her growth hormone level is restored to an ideal state with the use of somatotropin HGH injections.

Somatropin Side Effects

Somatropin Therapy Doctor

All medications come with warnings of risks and side effects, and the same holds true for somatotropin HGH. The most important thing that everyone should remember is that all medications, no matter what they are, should be used as directed by the prescribing physician. Pharmaceutical products should not be sold to or shared with others.

Administering the prescribed somatropin dosage will help to reduce the risk of developing any adverse reactions to this medication. The doctor – typically a hormone replacement therapy specialist – will carefully determine the proper dosage after reviewing blood test and physical examination results, as well as ensuring that there are no other medical conditions that could interfere with treatment after going over the clients completed medical history form.

There may be times when a person’s body responds to this treatment with certain somatropin side effects, but these are typically mild and often go away on their own within a few weeks as the body gets used to the increase in growth hormone. In some instances, the doctor will reduce the dosage to reverse the side effects, and then once the individual has stabilized, the dosage may be slowly increased. It is for this reason that HRT specialists typically start out with lower dosages in adults over sixty and gradually increase the medication administered over an extended period of time.

How to Get Somatropin HGH

Somatropin growth hormone must be prescribed by a doctor following blood testing that shows a valid GH deficiency. It should not be used by individuals that have no legitimate need for this medication, as that is what causes adverse effects.

The purchase of somatropin online can be dangerous as companies that do not require valid doctor’s prescriptions are operating illegally and are often located overseas. This can result in receipt of products that are contaminated with bacteria, laden with toxic ingredients, expired, diluted, or some other form of medication that is not human growth hormone.

Working with an experienced hormone replacement specialist will result in receiving the proper somatropin cycle that has been customized for your needs. This is the only recommended method for obtaining HGH injections.
