Nandrolone Cypionate Injection is an anabolic-androgenic steroid (AAS) used to promote muscle growth, improve red blood cell production, and treat certain medical conditions associated with muscle wasting and anemia. It is a long-acting ester of nandrolone, allowing slow release and prolonged action after intramuscular injection.

Here are the key details:

1. Composition and Form

• Active ingredient: Nandrolone Cypionate.

• Supplied as a sterile solution for intramuscular (IM) injection, usually in an oil base.

• Available in single-dose ampoules or multi-dose vials.

2. Mechanism of Action

• Binds to androgen receptors in muscle, bone, and other tissues.

• Promotes protein synthesis, nitrogen retention, and red blood cell production, supporting muscle growth and recovery.

• Has low estrogenic activity compared to testosterone, reducing water retention but may still convert to estrogen to a small extent.

• Exhibits relatively low androgenic effects, making it somewhat favorable for patients who are sensitive to androgenic side effects.

3. Indications

Medical use:

• Anemia associated with chronic kidney disease or chemotherapy.

• Muscle wasting in chronic illnesses or after severe trauma.

• Certain cases of osteoporosis in men.

Non-medical / illicit use:

• Bodybuilding and athletic performance enhancement (not recommended due to safety risks).

4. Administration

• Administered intramuscularly, typically every 1–4 weeks depending on dose and condition.

• Dose is weight- and condition-dependent in clinical settings.

• Slow-release formulation allows less frequent injections than short-acting anabolic steroids.

5. Side Effects

Androgenic effects:

• Acne, oily skin.

• Increased facial/body hair.

• Male pattern baldness in predisposed individuals.

Endocrine effects:

• Suppression of natural testosterone production with long-term use.

• Altered libido or mood changes.

Cardiovascular/metabolic effects:

• Changes in cholesterol (increased LDL, decreased HDL).

• Potential risk of cardiovascular strain with high doses.

Other effects:

• Virilization in women (deepened voice, menstrual irregularities, hirsutism).

• Rare liver toxicity (less than oral anabolic steroids).

6. Contraindications

• Hypersensitivity to nandrolone or other components.

• Pregnancy and breastfeeding (can virilize female fetus/infant).

• Prostate or breast cancer in men.

• Severe liver, kidney, or heart disease.

7. Precautions

• Monitor hormone levels, liver function, and lipid profile during prolonged therapy.

• Use caution in adolescents due to risk of premature epiphyseal closure (affecting growth).

• Avoid combining with other anabolic steroids unless medically supervised.

8. Storage

• Store at controlled room temperature, protected from light.

• Use aseptically; discard unused portions of single-dose vials.
