Testosterone stearate

Overview

Chemical structure of testosterone stearate

Testosterone stearate is a synthetic androgen and anabolic steroid that is a derivative of testosterone. It is an ester of testosterone, specifically the stearate ester, which is used to modify the pharmacokinetics of the parent hormone.

Chemical Structure

Testosterone stearate is characterized by the attachment of a stearate group to the 17-beta hydroxyl group of testosterone. This modification increases the lipophilicity of the molecule, allowing it to be administered in an oil-based solution for intramuscular injection.

Pharmacology

The esterification of testosterone with stearic acid results in a compound with a prolonged duration of action compared to unmodified testosterone. This is due to the slow release of the active hormone from the injection site into the bloodstream, where it is then hydrolyzed to free testosterone.

Clinical Use

Testosterone stearate is used in the treatment of hypogonadism in males, where it helps to restore normal levels of testosterone. It may also be used in certain cases of delayed puberty and in hormone therapy for transgender men.

Administration

Testosterone stearate is typically administered via intramuscular injection. The frequency of administration depends on the specific formulation and the clinical needs of the patient.

Side Effects

As with other testosterone esters, potential side effects of testosterone stearate include acne, gynecomastia, increased red blood cell count, and mood changes. Long-term use can lead to suppression of the hypothalamic-pituitary-gonadal axis.
