Overview of Nandrolone Decanoate

Nandrolone Decanoate is an injectable anabolic steroid widely used in 8-12 week bulking cycles by bodybuilders, often stacked with a form of Testosterone. It is considered a “classic” and remains one of the most popular anabolic steroids among athletes due to its proven track record. This steroid is known for its ability to retain water in the body, which accelerates muscle growth during the cycle.

Pharmacological Category

• Pharmacological Category: Anabolic-androgenic steroid
• Anabolic Activity Index: 150%
• Androgenic Activity Index: 30%

Mechanism of Action

Nandrolone Decanoate is an injectable anabolic androgenic steroid that enhances hemoglobin and red cell mass, making it useful in treating anemia caused by renal failure. It cannot be converted to dihydrotestosterone by the enzyme 5-alpha reductase, which means it has no effect on the prostate. Instead, Nandrolone metabolizes to dihydronandrolone. It binds to androgen receptors and also stimulates muscle growth through non-receptor mediated mechanisms.

Side Effects

Nandrolone can inhibit the body’s own testosterone production and increase prolactin levels while inhibiting the secretion of gonadotropic hormones. This may lead to reduced testosterone levels in the blood and activation of progesterone receptors, potentially causing a drop in libido, which usually returns within a month after finishing the course. It is often necessary to use an anti-progestin drug to counteract the steroid’s progestin effects. Notably, Nandrolone does not convert into estrogens and is not toxic to the liver.

Dosage Recommendations

Nandrolone Decanoate is administered via intramuscular injection.

• Effective Dose: 200-500 mg per week

As with any anabolic steroid, it is important to approach Nandrolone Decanoate with caution to minimize potential risks and side effects.
