How does somatropin work?

Somatropin is lab-made human growth hormone, identical to the hormone the pituitary gland makes. This site's profile says it switches on growth hormone receptors directly. That raises IGF-1 and drives growth, protein building, and other effects on how the body uses energy. The body clears half of a shot under the skin in about 3 to 4 hours. Its molecular weight is 22,124 daltons. It is FDA approved for growth hormone deficiency and several other listed uses. In 24 adults with growth hormone deficiency, six months of it raised lean mass by 5.5 kg and cut fat by 5.7 kg compared with a dummy shot, with no change in body weight. In 60 adults with a failing pituitary gland who were taken off growth hormone for four months, IGF-1 fell from 168 to 98 micrograms per litre. Two parts of their quality of life got worse, and their waist and deep belly fat grew. Those are results from treating a deficiency. They are not a finding in people whose own growth hormone is normal. Drugs like ipamorelin set off a burst of your own growth hormone. Somatropin is the hormone itself.
