Nandrolone Phenylpropionate (NPP) 100mg/mL

Nandrolone Phenylpropionate – Nandrobolin General Description

NPP (the popular sports drug Nandrobolin) is an anabolic-androgenic steroid with its active agent being nandrolone phenylpropionate. The active agent is notable due to its short half-life of 2-4 days compared to nandrolone decanoate or “Deca” (7-10 days). Phenylpropionate produces slight fluid retention and goes better in combination with androgenic drugs than nandrolone decanoate. The drug is mainly used by bodybuilders, weightlifters, powerlifters and other athletes to gain muscle mass and improve strength.

Nandrolone Phenylpropionate Benefits

NPP’s ester chain is two times shorter compared to decanoate, which results in the active component rapidly entering the bloodstream and quickly starting its action. This produces some of the drug’s benefits:

• the short half-life reduces the risks of adverse reactions;
• in cases of manifesting side effects or poor tolerance to the drug cycle it’s possible to stop the injections and remedy the situation without supplementary drugs.

The drug’s primary disadvantage is its need for frequent injections, but this is not a significant downside compared to shorter esters. Nandrolone phenylpropionate metabolites get excreted from the body for a long stretch of time – traces of using the anabolic steroid can be detected 18-24 months after completing the cycle, which is why the drug is not used by competing athletes. The main positive effects of NPP’s usage are as follows:

• Increased muscle mass. Phenylpropionate stimulates protein synthesis and produces proper nitrogen balance. The drug reduces the breakdown of cellular protein, which allows for the most favorable conditions for muscle growth.
• Slight fluid retention – in this exact case water plays the part of joint fluid (a natural lubricant for joints).
• Improved absorption of amino acids.
• Stimulated collagen secretion and calcium retention in the body, which increases bone density.
• Eliminated joint and ligament pains, increased joint mobility. The steroid is recommended for athletes that subject their locomotive systems to heavy loads.

The effects of Phenylpropionate are very similar to those of Decanoate, as both drugs are derivatives of Nandrolone that differ only in their duration of activity. Nandrolone is not a potent androgen, so it does not produce acne, oily skin, excessive hair growth throughout the body or baldness. Compared to testosterone and other androgenic substances, phenylpropionate is less likely to cause adverse reactions.
On average, a single solo cycle of Nandrolone Phenylpropionate will lead to significant increases in muscle volume, all the while muscles will be well-defined and lean without excess water or fat deposits. The drug affects the improvement of the athlete’s physical abilities – a standard cycle results in strength increases of 15%. Nandrolone increases the amount of red blood cells in the body and stimulates the saturation of muscle fibers at 100% with oxygen, nitrogen and other nutrients. It promotes protein synthesis and its absorption; NPP produces several times faster protein assimilation.

NPP Possible Side Effects

Nandrolone has a slight tendency to aromatize, while adverse reactions are caused by an increase in the concentration of prolactin in the body. Exceeded dosages of the drug may lead to prolactin gynecomastia (its symptoms don’t cause itching in the nipple area, but tissue swelling and the formation of lumps), decreased sexual vigor, decreased libido during the cycle, flaccid erection.

It is possible to eliminate the negative reactions by using special drugs that reduce the concentration of prolactin like Cabergoline (Dostinex) or Bromocriptine. Nandrolone suppresses the secretion of endogenous testosterone in the body and inhibits the production of gonadotropins, which results in prolonged recovery processes after the cycle.

NPP Administration and Dosage

NPP is characterized by the short half-life of the active substance, which is why the injection solution has to be administered often – at least 2 times a week. Intramuscular injections are often made every 3-4 days. The optimal dosage of the steroid for a single administration is 150-200 mg. The total weekly dosage shouldn’t exceed 300-400 mg. 3-5 days after the completion of the solo cycle users should start PCT using clomiphene citrate – Clomid. Using Tamoxifen for post-cycle therapy is fraught with negative side reactions as it increases progestin activity, which results in flaccid erection, gynecomastia and other adverse symptoms.

NPP Combined Cycles

Nandrolone phenylpropionate can be combined with a variety of anabolic steroids; up to 3 drugs can be used during a cycle simultaneously. NPP in combination with other steroids creates a synergistic effect in which drugs enhance the positive effects of each other. A combined cycle may look like this:

• NPP + Turinabol + Winstrol. 300 mg of Nandrolone injected weekly, 50 mg of Turinabol daily and 40 mg of Winstrol injected daily.
• NPP + Masteron + testosterone propionate. 250 mg of drostanolone enanthate injected weekly, 50 mg of testosterone propionate daily and 300 mg of nandrolone phenylpropionate weekly.
• NPP + testosterone propionate + Winstrol. 300 mg of Nandrolone injected weekly, 50 mg of testosterone propionate daily and 40 mg of Winstrol injected daily.

It is recommended to avoid using several oral steroids in combined cycle, as this increases the toxic impact on the liver. If the duration of the cycle exceeds 4-5 weeks, then users should add Testosterone (Propionate, Enanthate) while reducing the total dosage of other steroids.
