Nandrolone Phenylpropionate, commonly known as Nandrolone-F, is a remarkable injectable drug that has gained prominence in both medical and sports circles. Manufactured by SP-Laboratories, this compound has garnered attention for its potential in various realms, from bodybuilding to therapeutic applications. In this article, we’ll delve into the general description, indications, contraindications, uses in bodybuilding and sports, medical actions, combinations with other drugs, recommended dosage, and potential side effects of Nandrolone-F.

General Description:

Nandrolone Phenylpropionate is a synthetic anabolic steroid that belongs to the nandrolone family. It is characterized by a shorter ester, making it distinct from its longer-acting counterpart, Nandrolone Decanoate. The shorter ester results in a quicker release and peak concentration of the compound in the bloodstream. This allows for more precise control over dosing and reduced retention time in the body compared to other forms of nandrolone.


Nandrolone-F was initially developed for therapeutic purposes, mainly to treat conditions like anemia, osteoporosis, and muscle-wasting diseases. It stimulates erythropoiesis, leading to increased red blood cell production, and enhances bone mineral density, making it a valuable option in medical treatment. However, its off-label use has become prevalent due to its anabolic properties, which have piqued the interest of athletes and bodybuilders.


While Nandrolone-F has shown therapeutic potential, it comes with specific contraindications that need to be considered. Individuals with a history of hypersensitivity to nandrolone compounds, prostate or breast cancer, liver or kidney dysfunction, and cardiovascular issues should avoid its usage. Pregnant and lactating women should also refrain from using the drug due to potential risks.

Uses in Bodybuilding and Sport:

Nandrolone-F’s anabolic properties make it a sought-after compound in bodybuilding and sports. It aids in promoting muscle growth, enhancing strength, and improving overall athletic performance. Athletes appreciate its ability to help with muscle recovery and endurance, contributing to more intense training sessions. However, it’s essential to note that the use of Nandrolone-F for such purposes may raise ethical and legal concerns within competitive sports.

Medical Action:

The action of Nandrolone-F stems from its interaction with androgen receptors and its influence on protein synthesis. It stimulates nitrogen retention, leading to an increase in muscle mass. Additionally, it promotes the production of insulin-like growth factor (IGF-1), fostering tissue repair and growth. Its anti-inflammatory properties further contribute to enhanced recovery after intense workouts.

Combinations with Other Drugs:

In the realm of bodybuilding, Nandrolone-F is often used in combination with other anabolic steroids to amplify its effects. Stacking it with compounds like testosterone can lead to potent synergistic results. However, caution is advised, as combining multiple substances can increase the risk of adverse effects. Consulting a medical professional before initiating any stacking regimen is crucial.


The recommended dosage of Nandrolone-F varies based on the user’s experience level, goals, and tolerance. Typically, doses range from 100mg to 300mg per week, administered through intramuscular injections. Novice users should start with lower doses to assess their response and tolerance, gradually adjusting as needed. Advanced users might opt for higher doses, but this increases the risk of potential side effects.

Side Effects:

Like any other anabolic steroid, Nandrolone-F is associated with potential side effects. These can include estrogenic effects such as gynecomastia and water retention, androgenic effects like acne and hair loss, cardiovascular issues, and suppression of natural testosterone production. It’s crucial to monitor for these effects and prioritize post-cycle therapy (PCT) to help restore hormone balance after discontinuing usage.


Nandrolone Phenylpropionate, marketed as Nandrolone-F and manufactured by SP-Laboratories, presents a versatile compound with both medical and performance-enhancing potential. Its anabolic properties have found favor among athletes and bodybuilders seeking enhanced muscle growth and improved athletic performance. However, responsible usage and close monitoring of its effects are essential to mitigate potential risks. As with any pharmaceutical substance, consulting a medical professional before usage is strongly recommended to ensure safe and informed use of Nandrolone-F.
