Deca-Instabolin 50 mg contains Nandrolone Decanoate, an anabolic-androgenic steroid (AAS). It is primarily used in medical settings to treat conditions that cause muscle wasting, severe weight loss, or anemia. It promotes muscle growth, bone density, and red blood cell production. In some cases, it is misused in bodybuilding or athletics, which carries significant health risks.

Mechanism of action:
Nandrolone is an androgen receptor agonist. It binds to androgen receptors in muscles and bones, stimulating protein synthesis, nitrogen retention, and red blood cell production. This helps increase muscle mass, strength, and bone density.

Uses:

• Medical use: to treat muscle wasting due to chronic illness, osteoporosis, or severe weight loss

• Anemia treatment: stimulates red blood cell production

• Sometimes misused for bodybuilding or athletic performance (not medically recommended)

Adverse effects:
Common side effects include acne, oily skin, fluid retention, and increased appetite. Serious side effects may include:

• Hormonal imbalances (low natural testosterone, infertility, testicular atrophy)

• Liver toxicity

• Heart problems (high blood pressure, cholesterol changes, risk of heart attack or stroke)

• Mood changes (aggression, irritability)

• Virilization in women (deep voice, facial hair, menstrual irregularities)
