Introduction

Nandrolone Phenylpropionate (NPP) is an anabolic steroid used in medicine and bodybuilding. It is a derivative of testosterone and is used primarily to promote muscle growth and improve bone density. It is known for its shorter ester compared to other nandrolone derivatives, which results in a faster onset and shorter duration of action.

Uses

Nandrolone Phenylpropionate is used for:

  • Treating anemia and osteoporosis by promoting red blood cell production and bone health.
  • Supporting muscle mass and strength in patients with chronic wasting diseases or severe weight loss.
  • As part of hormone replacement therapy to manage testosterone deficiency in men.

Mechanism of Action

Nandrolone Phenylpropionate works by binding to androgen receptors in muscle and bone tissues. This binding promotes protein synthesis and increases muscle mass and bone density. It also stimulates erythropoiesis (red blood cell production) by enhancing erythropoietin levels in the kidneys.

How Long Does It Take to Work?

The effects of Nandrolone Phenylpropionate can be observed within a few weeks of starting treatment. Muscle growth and increased bone density typically become noticeable after about 4 to 6 weeks. For medical conditions such as anemia, improvements in red blood cell count may also be seen within a similar time frame.

Absorption

Nandrolone Phenylpropionate is administered intramuscularly. After injection, it is gradually absorbed into the bloodstream. The rate of absorption can be influenced by the injection site and formulation.

Route of Elimination

Nandrolone Phenylpropionate is metabolized primarily in the liver. It is excreted mainly through urine as metabolites. The half-life of the drug influences how long it remains active in the body and impacts the frequency of administration.

Dosage

As an adjunct to specific therapies and dietary measures in pathologic conditions characterized by a negative nitrogen balance: Recommended dose is 25-50 mg every week.

For the palliative treatment of selected cases of disseminated mammary carcinoma in women: Recommended dose is 50 mg every week.

Osteoporosis: Recommended dose is 50 mg every week.

For an optimal therapeutic effect, it is necessary to administer adequate amounts of vitamins, minerals and protein in a calorie-rich diet. Nandrolone Phenylpropionate should be administered by deep intramuscular injection.

The dosage of Nandrolone Phenylpropionate varies based on the condition being treated:

  • For anemia and osteoporosis: 50 to 100 mg administered intramuscularly every 1 to 4 weeks.
  • For muscle wasting and strength improvement: 50 to 100 mg every 1 to 2 weeks, depending on patient response and tolerance.

Dosage adjustments are made based on individual patient needs, response, and side effects.

Administration

Nandrolone Phenylpropionate is administered intramuscularly, typically into the gluteal or deltoid muscles. It should be injected according to the prescribed schedule and technique to ensure proper absorption and minimize side effects.
