Testosterone propionate/testosterone enanthate/testosterone undecylenate

Testosterone propionate, testosterone enanthate, and testosterone undecylenate are three different testosterone esters used in androgen replacement therapy and for other medical purposes. These compounds are synthetic derivatives of the naturally occurring androgen and anabolic steroid testosterone.

Testosterone Propionate

Testosterone propionate is a short-acting ester of testosterone. It is known for its rapid onset of action and is typically administered via intramuscular injection. Due to its short half-life, it requires frequent dosing, often every other day or every three days. This ester is commonly used in the treatment of hypogonadism in males and certain types of breast cancer in females.

Testosterone Enanthate

Testosterone enanthate is a long-acting ester of testosterone. It is one of the most commonly used testosterone esters for androgen replacement therapy. It is typically administered via intramuscular injection every one to four weeks. Testosterone enanthate is used to treat conditions such as hypogonadism, delayed puberty in males, and certain types of breast cancer in females.

Testosterone Undecylenate

Testosterone undecylenate is another long-acting ester of testosterone. It is less commonly used compared to testosterone enanthate but serves similar purposes in androgen replacement therapy. It is administered via intramuscular injection and has a longer half-life, allowing for less frequent dosing, typically every four to six weeks.

Medical Uses

These testosterone esters are primarily used in the treatment of:

• Hypogonadism in males
• Delayed puberty in males
• Certain types of breast cancer in females
• Gender dysphoria in transgender men
