    • Description

    Nandrolone phenylpropionate (NPP) is an injectable form of the anabolic steroid nandrolone. It is a short-acting nandrolone. The properties of this drug are very similar to those of nandrolone decanoate (DECA). The difference lies in the speed with which nandrolone is released into the blood. Nandrolone decanoate (DECA) can provide 2-3 weeks of nandrolone release, while nandrolone phenylpropionate (NPP) only provides a week of nandrolone release. It is highly anabolic, can rapidly increase muscle and body weight, has no obvious androgenic side effects, and can relieve joint pain. Suitable for beginners and also suitable for the muscle-building phase.

    NPP structure characteristics

    Nandrolone phenylpropionate (NPP) is a derivative of nandrolone in which a carboxylate (phenylpropionate) has been attached to the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids and are absorbed more slowly in the injected area. Once in the bloodstream, the ester is removed to produce free (active) nandrolone. Esterified steroids are designed to prolong the window of therapeutic effect after administration, allowing for less frequent injections compared to injections of free (unesterified) steroids. Nandrolone phenylpropionate reaches peak nandrolone release 24-48 hours after deep intramuscular injection and declines to near baseline levels within a week.

    Nandrolone phenylpropionate Benefits

    1.Increases IGF-1 production: Insulin-like growth factor 1 (IGF-1) is a potent anabolic hormone that is also essential to our body's ability to recover. This is a hormone that affects almost every cell in the body.

    2.Suppression of glucocorticoids: Known as the stress hormone (cortisol), these hormones are critical to our health and well-being. However, when glucocorticoids dominate, they also promote muscle loss and fat gain. Strenuous activity can cause an increase in stress hormones. Hormones like nandrolone reduce the production of stress hormones.

    3.Increased Nitrogen Retention: All muscle tissue contains 16% nitrogen. If retention drops, we slip into a catabolic state. The more we keep, the more anabolic we leave behind.

    4.Increased protein synthesis: Increases the rate at which cells build proteins (the building blocks of muscle tissue).

    5.Increased red blood cell count: Red blood cells carry oxygen into and through the blood. Greater efficiency leads to enhanced muscular endurance and recovery.

    6.Increases Collagen Synthesis and Bone Mineral Content: This refers to the strength and ability of bones and cartilage to strengthen and provide healing relief. This applies more in joints than anywhere else.

    Nandrolone Phenylpropionate (NPP) Dosage

    Nandrolone Phenylpropionate is widely used by bodybuilders for bulking and cutting cycles.

    An effective NPP dose for male bodybuilders is 200-400 mg/week.

    This level is sufficient for most users to see measurable gains in lean muscle mass and strength. Note that due to the fast-acting nature of phenylpropionate, the weekly dose is usually divided into two administrations.

    Nandrolone Phenylpropionate (NPP) Side Effects

    Although nandrolone phenylpropionate (NPP) shows strong benefits in bodybuilding, it may cause side effects due to individual differences, environment, dosage and other factors. The potential side effects are as follows:

    1.Edema: Nandrolone phenylpropionate may cause fluid retention and cause edema. This can make the muscles look undersized, affecting the bodybuilder's muscle definition and appearance.

    2.Metabolic problems: The use of nandrolone phenylpropionate may interfere with the metabolic process, resulting in a decrease in metabolic rate. This can affect the body's ability to burn fat and build muscle mass.

    3.Hormone imbalance: Nandrolone phenylpropionate is a synthetic hormone, which may cause endogenous hormone imbalance during use. This can include increased androgen levels, decreased estrogen levels, etc., which can lead to problems such as sexual dysfunction and menstrual disturbances.

    4.Cardiovascular problems: The use of nandrolone phenylpropionate may increase cardiovascular risks, including high blood pressure, increased heart burden, and heart attack.

    5.Suppression of the immune system: Nandrolone phenylpropionate may suppress the function of the immune system, increasing the risk of infection and disease.

    6.Mental and emotional problems: The use of nandrolone phenylpropionate may cause mental and emotional changes, including anxiety, depression, irritability, etc.

    Nandrolone phenylpropionate side effects and severity can vary depending on individual differences, dosage, and how it is used. Before considering using nandrolone phenylpropionate, you should start using it at a low dose. Once serious side effects occur during use, you should stop using it immediately and consult a doctor or senior fitness trainer if necessary.
