Product Overview
Duraplex 100 mg by Axiolabs
Duraplex 100 mg is an oil-based nandrolone phenylpropionate injectable manufactured by Axiolabs and dosed at 100 mg/mL in a 10 mL vial.
Nandrolone Phenylpropionate Injectable
Duraplex 100 mg is an injectable anabolic-androgenic steroid containing nandrolone phenylpropionate, a short-acting 19-nor testosterone derivative. Nandrolone phenylpropionate, also known as NPP, is the phenylpropionic acid ester of nandrolone. Unlike the longer-acting decanoate ester, the phenylpropionate ester provides a faster release profile with a biological half-life of approximately 4.5 days following intramuscular injection . The compound is supplied as a sterile oleaginous solution for intramuscular administration.
In clinical medicine, nandrolone phenylpropionate has been used for the management of conditions requiring anabolic support, including anemia associated with renal insufficiency, osteoporosis, and catabolic states . Anabolic steroids, including nandrolone esters, suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis . In bodybuilding and performance-enhancement settings, nandrolone phenylpropionate is commonly referenced as an alternative to the longer-acting decanoate ester for its faster onset and quicker clearance, which allows for more flexible cycle planning . Such use falls outside approved medical indications.
Nandrolone supports muscle protein synthesis and nitrogen retention through androgen receptor binding, but its 19-nor structure produces a distinct pharmacological profile compared to testosterone. The phenylpropionate ester allows for a more rapid onset of action and faster clearance than the decanoate ester, which is often referenced as beneficial for those who want to avoid the prolonged detection window associated with the decanoate . Non-medical use at supraphysiologic doses increases exposure to adverse effects including suppression of endogenous testosterone production, lipid profile disruption, and potential hepatic complications.
Key Benefits of Duraplex 100 mg
- Short-acting phenylpropionate ester with ~4.5-day half-life
- Faster onset and quicker clearance than decanoate ester
- Commonly referenced for mass-building and joint support
- MCT oil carrier for smooth, consistent formulation
- 19-nor structure distinct from testosterone-based compounds
Carrier Oil
MCT Oil Formulation
Duraplex 100 mg uses MCT oil as its carrier oil, providing the oil base for the nandrolone phenylpropionate formulation.
Product Profile
Nandrolone Phenylpropionate Profile
Nandrolone phenylpropionate is a short-acting 19-nor anabolic steroid with a distinct pharmacological profile, characterized by its phenylpropionate ester and faster onset and clearance compared to the decanoate ester.
Short-Acting 19-Nor Injectable Anabolic
Nandrolone phenylpropionate is the phenylpropionic acid ester of nandrolone (19-nortestosterone). The phenylpropionate ester is shorter than the decanoate ester, which allows for a faster release of nandrolone from the injection site and a shorter duration of action . The compound is supplied as a sterile oleaginous solution for intramuscular injection, typically containing nandrolone phenylpropionate in a suitable carrier oil .
As a 19-nor compound, nandrolone lacks the 19-methyl group present in testosterone, which alters its interaction with enzymes and receptors. This structural difference contributes to nandrolone's relatively lower androgenic activity compared to testosterone and its different metabolic fate. The phenylpropionate ester provides a half-life of approximately 4.5 days, supporting more frequent administration than the decanoate ester but faster clearance .
Nandrolone phenylpropionate is a Schedule III controlled substance in the United States with accepted medical uses . Clinical use is limited to specific indications, and the drug has not been shown to be safe and effective for the enhancement of athletic performance .
Defining Characteristic
Short-Acting Phenylpropionate Ester
The phenylpropionate ester provides nandrolone with a faster onset and quicker clearance compared to the decanoate ester, supporting more flexible cycle planning and a shorter detection window.
Duraplex 100 mg vs Other Axiolabs Preparations
Axiolabs produces several injectable anabolic products referenced in different contexts. Duraplex 100 mg is a nandrolone phenylpropionate product, placing it among the injectable options alongside Decaplex 250 (nandrolone decanoate) and Testaplex C 250 (testosterone cypionate).
For bodybuilders considering longer-acting alternatives, Decaplex 250 offers the decanoate ester with a slower release and longer detection window. For those seeking a short-acting testosterone base to stack with NPP, Testaplex P 100 (testosterone propionate) is commonly referenced. The choice between these compounds depends on individual goals, cycle structure, and tolerance for suppression of endogenous testosterone production.
Dosage & Usage
Duraplex 100 mg Dosage & Usage
The information below is provided for educational reference only. Nandrolone phenylpropionate is a prescription anabolic steroid; medical use requires appropriate diagnosis and clinical supervision. Non-medical use falls outside approved indications and is illegal in many jurisdictions.
Typical Dosage Ranges
In medical practice, nandrolone phenylpropionate dosing is individualized based on the specific indication. In non-medical bodybuilding contexts, nandrolone phenylpropionate is commonly referenced in the range of 50–100 mg every other day, which equates to approximately 200–400 mg per week . Due to the shorter phenylpropionate ester, doses are typically administered every other day or three times per week to maintain stable blood levels .
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Bodybuilding (non-medical, moderate) | 50–100 mg EOD (≈200–350 mg/week) | Every other day |
| Bodybuilding (non-medical, standard) | 100 mg EOD (≈350–400 mg/week) | Every other day |
| Advanced (non-medical) | 150 mg EOD (≈500+ mg/week) | Every other day |
Stacking & Cycle Considerations
In non-medical bodybuilding contexts, nandrolone phenylpropionate is frequently referenced as a base compound in bulking cycles and is often stacked with testosterone to mitigate libido-related side effects associated with 19-nor compounds. It may also be combined with oral compounds such as Methanoplex during the initial weeks of a mass-building protocol. A typical cycle of nandrolone phenylpropionate lasts 8–12 weeks .
Because NPP clears faster than the decanoate ester, it is sometimes preferred by users who want more control over cycle timing and a shorter detection window.
Managing Side Effects
Nandrolone phenylpropionate can cause significant suppression of endogenous testosterone production, which may result in libido changes, mood alterations, and erectile dysfunction. It also has a reputation for causing water retention and elevated blood pressure in some users. Lipid profile monitoring is relevant as anabolic steroids have been reported to decrease high-density lipoprotein and sometimes increase low-density lipoprotein .
Because nandrolone is a 19-nor compound, it is not aromatized to estrogen to the same extent as testosterone, but it can still contribute to estrogenic side effects through other pathways. Managing these effects requires attention to cycle composition and individual response.
Post-Cycle Therapy (PCT)
Nandrolone phenylpropionate is suppressive to the hypothalamic-pituitary-gonadal axis, and post-cycle therapy is commonly recommended after a cycle to support recovery of endogenous testosterone production. Agents such as Clomiplex and Tamoxiplex are frequently referenced for this purpose. Due to the shorter phenylpropionate ester, PCT can typically begin sooner after the final injection compared to the decanoate ester.

Safety & Information
Nandrolone Phenylpropionate Safety Information
Nandrolone phenylpropionate is a prescription anabolic steroid that can affect hepatic, cardiovascular, and endocrine function. Medical use requires appropriate diagnosis and ongoing clinical supervision.
Important Safety Information
Nandrolone phenylpropionate carries boxed warnings for serious hepatic and cardiovascular risks. Peliosis hepatis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, has been reported in patients receiving androgenic anabolic steroid therapy. These cysts are sometimes present with minimal hepatic dysfunction but at other times have been associated with liver failure, and are often not recognized until life-threatening liver failure or intra-abdominal hemorrhage develops .
Liver cell tumors have also been reported. Most often these tumors are benign and androgen-dependent, but fatal malignant tumors have been reported . Blood lipid changes associated with increased risk of atherosclerosis are seen in patients treated with androgens and anabolic steroids, including decreased high-density lipoprotein and sometimes increased low-density lipoprotein .
Important
Non-Medical Use
Nandrolone phenylpropionate has not been shown to be safe and effective for the enhancement of athletic performance, and the FDA labeling explicitly states that the drug should not be used for such purpose because of the potential risk of serious adverse health effects . Non-medical use falls outside approved indications and is illegal in many jurisdictions.
Potential Adverse Effects
Hepatic effects are a primary concern with anabolic steroid therapy. Cholestatic jaundice is associated with therapeutic use of anabolic and androgenic steroids, and edema may occur occasionally with or without congestive heart failure .
In men, postpubertal adverse effects can include inhibition of testicular function, testicular atrophy and oligospermia, impotence, and chronic priapism . Women should be observed for signs of virilization including deepening of the voice, hirsutism, acne, clitorimegaly, and menstrual irregularities. Discontinuation of drug therapy at the time of evidence of mild virilism is necessary to prevent irreversible virilization .
Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis . Lipid profile changes, including decreased HDL and sometimes increased LDL, have been reported and may have a serious impact on the risk of atherosclerosis and coronary artery disease .
Conditions Requiring Medical Evaluation
Nandrolone phenylpropionate is contraindicated in male patients with carcinoma of the breast or with known or suspected carcinoma of the prostate, in females with carcinoma of the breast with hypercalcemia, in pregnancy because of masculinization of the fetus, and in nephrosis or the nephrotic phase of nephritis . Caution is required in administering these agents to patients with cardiac, renal, or hepatic disease .
Monitoring During Therapy
Medically supervised anabolic steroid therapy typically involves periodic hemoglobin and hematocrit checks for polycythemia, serum lipid and HDL cholesterol determination, and liver function tests . These monitoring practices are relevant to medical use; non-medical use lacks the same clinical oversight.

Duraplex 100 mg FAQ
Answers to common questions about Duraplex 100 mg, nandrolone phenylpropionate, dosing, and product characteristics.
What is Duraplex 100 mg used for?
Duraplex 100 mg contains nandrolone phenylpropionate, an injectable anabolic steroid. In medical practice, nandrolone esters are used for conditions requiring anabolic support, including anemia of renal insufficiency and osteoporosis . In non-medical bodybuilding contexts, it is commonly referenced for mass-building and joint support, though such use falls outside approved indications and the drug has not been shown to be safe or effective for athletic performance enhancement .
How often should Duraplex 100 mg be injected?
Due to the short phenylpropionate ester with a half-life of approximately 4.5 days, nandrolone phenylpropionate is typically referenced as being administered every other day or three times per week to maintain stable blood levels . This is distinct from the longer-acting decanoate ester, which is usually administered once weekly.
Does Duraplex 100 mg require PCT?
Yes. Nandrolone phenylpropionate suppresses the hypothalamic-pituitary-gonadal axis, and post-cycle therapy is commonly recommended after a cycle to support recovery of endogenous testosterone production. Agents such as Clomiplex or Tamoxiplex are commonly referenced for this purpose. Due to the shorter ester, PCT can typically begin sooner after the final injection compared to the decanoate ester.
What does nandrolone phenylpropionate do?
Nandrolone phenylpropionate is an anabolic steroid that binds to androgen receptors and promotes nitrogen retention and protein synthesis. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis . Its 19-nor structure gives it a different pharmacological profile compared to testosterone.
How long does nandrolone phenylpropionate take to work?
The phenylpropionate ester provides a faster release profile compared to the decanoate ester, with noticeable effects sometimes reported within the first 1–2 weeks of use in bodybuilding discussions. Individual response varies, and these timelines are based on non-medical user reports rather than controlled clinical data for this specific use case.
Is nandrolone phenylpropionate the best injectable for bulking?
There is no universally "best" injectable for bulking. Nandrolone phenylpropionate is commonly referenced as a foundational compound for mass-building, but Decaplex 250 (nandrolone decanoate) and Testaplex C 250 (testosterone cypionate) are also widely used. The appropriate choice depends on individual goals, injection frequency preference, and tolerance for suppression.
What is the difference between nandrolone phenylpropionate and nandrolone decanoate?
Both are nandrolone esters, but they differ in release rate. Nandrolone phenylpropionate has a shorter ester chain and a half-life of approximately 4.5 days, supporting more frequent injections . Nandrolone decanoate has a longer ester and is typically referenced for less frequent administration. Axiolabs offers Decaplex 250 as its nandrolone decanoate product.
What is the difference between nandrolone phenylpropionate and testosterone propionate?
Nandrolone phenylpropionate is a 19-nor compound, while testosterone propionate is a testosterone ester. They have different pharmacological profiles, with nandrolone generally considered more suppressive to endogenous testosterone production. Testosterone is commonly used as a base compound alongside nandrolone in non-medical cycles to mitigate libido-related side effects. Axiolabs offers Testaplex P 100 as its testosterone propionate product.
Is 100 mg of nandrolone phenylpropionate a lot?
In non-medical bodybuilding contexts, 100 mg administered every other day (approximately 350–400 mg per week) is within the commonly referenced range for standard use . Duraplex 100 mg contains 100 mg/mL, so each 1 mL injection provides 100 mg. Dosage appropriateness depends on individual factors and the overall cycle context.
What strength is Duraplex 100 mg?
Duraplex 100 mg is labeled at 100 mg of nandrolone phenylpropionate per mL. It is supplied in a 10 mL vial, giving 1,000 mg of total labeled nandrolone phenylpropionate content per vial.
Is Duraplex 100 mg lab tested?
Lab testing information for Duraplex 100 mg is not available on this page. For product-specific testing inquiries, please contact customer support.
Can nandrolone phenylpropionate cause joint pain relief?
Nandrolone phenylpropionate is commonly referenced in non-medical bodybuilding contexts for its reputation for joint comfort, though this effect is not an approved medical indication and the mechanism is not fully established in clinical literature. Individual response varies, and any perceived joint benefits should be weighed against the significant risks associated with anabolic steroid use.
