How it works

Growth hormone with an albumin-binding tail: riding the blood's main protein, it lasts a week. For children and adults lacking it.

What it's made of

Human growth hormone (191 amino acids) with one change (L101C) where a tail that sticks to albumin is anchored. That is how it lasts a week.

What it's for

Prescribed for

Growth hormone deficiency in adults and in children from 2.5 years; in the US, also idiopathic short stature, children born small, and Noonan syndrome.
