Somatomedin C is the more correct medical term for insulin-like growth factor-1 or IGF-1.
The liver manufactures growth factors identified by numbers.
Somatomedin C and other growth factors are defined as protein peptides manufactured in the liver and play a role in growth hormone activities.
Somatomedin C is further defined as a human protein that is included with the IGF-1 gene.
In a person (mainly children) suspected of having a growth hormone deficiency or disorder, a doctor may perform a Somatomedin C test, which is effective in evaluating levels of human growth hormone in the body.
The Somatomedin C test is one of the most commonly performed in diagnosing some disorder of the pituitary gland.  Buy HGH-X2 online here.

Human growth hormone, manufactured by the pituitary gland, is known as somatotropin.
Somatomedin C (IGF-1) is manufactured in the liver as well as the muscles, hence its name as a growth factor.
Secretions are stimulated by growth hormone.
IGF-1 is a growth hormone that is responsible for overseeing linear growth as well as protein anabolism of growth hormone as manufactured by the pituitary gland.
Growth hormone manufactured by the pituitary (hGH) stimulates the production of insulin-like growth factors in the liver, which also work with hGH to promote growth and development in hundreds of cell types in the body.
Together, these two potent hormones stimulate growth and development of the majority of cells in the human body!
Bodybuilders interested in promoting muscular development, physique, and performance often turn to synthetic drugs to enhance their efforts.
These include anabolic androgenic steroids, synthetic growth hormone (somatotropin), as well as IGF-1.
Quite simply, growth hormone triggers production and secretions of insulin-like growth factors in the liver.
These factors have an influence on IGF-1 manufacture and paracrine tissues involved in tissue regeneration as well as the capability of altering differentiation and behaviors in certain cells. 
Note: Medical professionals do not condone nor recommend injecting into the body any hormone that is not required in the treatment of some type deficiency.
Doing so can increase levels of that specific hormone to higher than normal degrees, which has the very real potential of interfering with or disrupting other hormone levels.
This often creates a domino-like effect of issues, side effects, and disruptions in body organ and body system activities.
Hormone levels dip and rise throughout the day.
Levels also differ depending on age. For example – and measured in nanograms per milliliter – the following are averages of IGF-1 levels in a male body at any given time:
Levels of growth hormone and growth factors naturally decline as adolescents reach adulthood. The average adult male has levels ranging 42 to 110. 
However, even a person who has been diagnosed with lower than normal levels of growth hormone in the body may fall within the normal range for IGF-1.
Bodybuilders often turn to anabolic androgenic steroids as well as IGF-1 to promote and accelerate their muscle growth and development efforts.
Stimulating muscle cell growth is one of the main benefits for any athlete, but also provides a number of other benefits such as:
IGF-1 has also been noted to have some involvement in brain function including plasticity.
For generations, IGF-1 has been nicknamed a literal fountain of youth because of its potential to promote faster post-workout recovery and recuperation.
Bodybuilders often extol additional benefits of Somatomedin C/IGF-1 for its ability to improve retention of new muscle development as well as the potential to reduce body fat storage.
Before considering injections of Somatomedin C or IGF-1 for physical performance physique or enhancement benefits, take the time to research the potential side effects and adverse reactions.
Some are mild and temporary while others are much more serious.
Even in low dosages, IGF-1 has the potential to trigger a number of undesirable and alarming side effects.
Bodybuilders purchasing IGF-1 from underground sources don’t rely on dosage recommendations from medical professionals in the treatment of a growth hormone deficiency in children or an adult.
Average injections range anywhere between 15 mcg a day and as high as 100 mcg daily.
Bodybuilders can find a number of suggestions for dosages on bodybuilding websites and muscle building forum board discussion threads, but always be aware that every individual can react differently based on age, genetics, and body composition.
What about side effects?
Somatomedin C/IGF-1 side effects range from headaches to hormonal imbalances. Of serious concern is the potential for disruption of hormone levels and their activities in the body, especially that of insulin and the thyroid and parathyroid glands.Bovine Growth HormoneCJC-1295 PeptideHGH 30000HGH BoosterHGH Color TopsHGH CreamHGH ExtractionsHGH Fragment 176 191HGH PeptidesHGH ReleasersHGH SprayHGH SteroidsHGH StimulatorsOral HGH TabletsPituitary Growth HormonePure HGHRecombinant Bovine SomatotropinRecombinant Human Growth HormoneRHGHSomatomedin CSomatotropinSomatotropin HormoneSynthetic HGHTypes of HGH
