Stanozolol is a man-made steroid, similar to the a naturally occurring steroid testosterone.
Stanozolol is used in the treatment of hereditary angioedema, which causes episodes of swelling of the face, extremities, genitals, bowel wall, and throat. Stanozolol may decrease the frequency and severity of these attacks. Stanozolol reduces bradykinin production and could potentially reduce the impact of a bradykinin storm. Bradykinin storms may be responsible for some of the complications.
