Nandrolone Undecanoate

Chemical structure of Nandrolone Undecanoate

Nandrolone undecanoate is an anabolic steroid and a nandrolone ester. It is used in medicine and veterinary medicine to promote muscle growth and to treat certain medical conditions. Nandrolone undecanoate is known for its long-acting properties and is administered via intramuscular injection.

Pharmacology

Nandrolone undecanoate is a prodrug of nandrolone, meaning it is converted into the active form, nandrolone, in the body. Nandrolone is a synthetic anabolic-androgenic steroid (AAS) that mimics the effects of testosterone. It has a high anabolic to androgenic ratio, which makes it effective for promoting muscle growth with fewer androgenic side effects compared to testosterone.

Mechanism of Action

Nandrolone undecanoate works by binding to androgen receptors in muscle tissue, which leads to an increase in protein synthesis and muscle growth. It also enhances nitrogen retention in muscles, which is crucial for muscle repair and growth.

Medical Uses

Nandrolone undecanoate is used in the treatment of various medical conditions, including:

• Anemia
• Osteoporosis
• Cachexia associated with chronic illness
• Certain types of breast cancer

Side Effects

Like other anabolic steroids, nandrolone undecanoate can cause a range of side effects. These may include:

• Acne
• Gynecomastia
• Increased body hair
• Voice deepening
• Liver damage
• Cardiovascular issues

Legal Status

Nandrolone undecanoate is a controlled substance in many countries due to its potential for abuse and side effects. It is classified as a Schedule III controlled substance in the United States.
