Products description: Unique Pharma - NPP 100

This overview summarizes information on nandrolone phenylpropionate, the purported active substance in Unique Pharma - NPP 100, from a limited number of key scientific sources.

NPP 100 is a preparation based on nandrolone phenylpropionate, an anabolic-androgenic steroid (AAS). This nandrolone ester is characterized by a shorter duration of action compared to its counterpart, nandrolone decanoate, which allows for a faster release and clearance from the body [2, 4].

🧪Active Substance

Nandrolone phenylpropionate (NPP) is an injectable anabolic steroid and a prodrug of nandrolone. It possesses strong anabolic properties and moderate androgenic activity. NPP is used to increase muscle mass and red blood cell count [2, 4].

⚕️Established Medical Uses

Nandrolone phenylpropionate has several established medical uses, primarily for treating conditions related to wasting and bone loss. These include:

• Treatment of anemia associated with chronic renal failure and aplastic anemia [1, 2, 3].
• Therapy for osteoporosis, where it helps to increase bone mass [2, 3, 4].
• Use in catabolic states to stimulate protein synthesis and prevent muscle loss [3].

🔬Mechanism of Action

Nandrolone phenylpropionate acts by binding to androgen receptors in various tissues. This mechanism leads to the following effects:

• Anabolic effect: Stimulates protein synthesis in muscles, leading to an increase in muscle mass and strength [3].
• Erythropoiesis: Enhances the production of erythropoietin, which leads to an increase in red blood cells and improved oxygen transport [1, 3].
• Effect on bone tissue: Promotes calcium retention and increases bone density, making it effective for osteoporosis [2, 3].

⚠️Safety and Side Effects

The use of nandrolone phenylpropionate is associated with a risk of several side effects, especially when used in high doses or without medical supervision [2, 3]:

• Androgenic effects: In women, it can cause virilization (development of male characteristics such as voice deepening and body hair growth) and amenorrhea. In men, it can cause suppression of spermatogenesis and testicular atrophy [2, 3].
• Cardiovascular risks: May cause fluid retention (edema) and an increase in blood pressure [3].
• Hepatotoxicity: Although nandrolone is considered less hepatotoxic than other AAS, the risk of liver damage, including cholestatic jaundice, still exists [3].
• Endocrine disruptions: Suppresses endogenous testosterone production, which requires post-cycle therapy to restore hormonal balance [3].

💉Dosage and Administration (Non-Medical Context)

For medical purposes, dosages are strictly regulated and individually tailored. In a non-medical context, doses significantly exceed therapeutic levels and are determined by users based on unofficial sources, which greatly increases the risk of side effects [2, 3].
