Deca 500 mg is a high-concentration oil-based Nandrolone Decanoate injectable manufactured by Dragon Pharma and dosed at 500 mg/mL in a 10 mL vial.
Deca 500 mg contains nandrolone decanoate, a long-acting anabolic-androgenic steroid (AAS) belonging to the 19-nor-testosterone class. Its decanoate ester produces a prolonged release profile, making it one of the most recognized injectable compounds in bodybuilding and a medically approved agent for specific clinical indications. This 500 mg/mL concentration is significantly higher than standard 200 mg/mL and 300 mg/mL preparations, making it a product typically referenced by experienced users who require reduced injection volumes.
In clinical practice, nandrolone decanoate is indicated for the management of anemia of renal insufficiency, where it has been shown to increase hemoglobin and red cell mass. It has also been investigated for postmenopausal osteoporosis and other catabolic conditions. In non-medical bodybuilding settings, nandrolone decanoate is commonly referenced for its ability to support muscle mass gains, joint comfort, and recovery during bulking or off-season cycles.
Nandrolone differs structurally from testosterone by lacking a carbon-19 methyl group, which contributes to its relatively lower androgenic activity compared to testosterone. This characteristic is often cited in non-medical contexts as a reason for the compound's popularity, though nandrolone still carries significant androgenic and progestogenic activity that can produce adverse effects. The 500 mg/mL concentration means that even modest injection volumes deliver substantial amounts of the active compound.
Deca 500 mg uses MCT oil as its carrier, providing an oil base for the nandrolone decanoate formulation. The 500 mg/mL concentration is among the highest available for nandrolone decanoate, allowing experienced users to administer equivalent doses with reduced injection volume compared to lower-concentration products.
Nandrolone decanoate is a long-acting 19-nor-testosterone derivative designed for gradual release after intramuscular administration. Its extended release characteristics distinguish it from shorter-acting nandrolone preparations such as nandrolone phenylpropionate (NPP).
The decanoate ester slows the release of nandrolone from the injection site, producing a longer duration of activity than unesterified nandrolone or shorter esters. Once released, nandrolone exerts anabolic and androgenic effects through androgen receptor binding, with relatively lower androgenic potency than testosterone. The elimination half-life of nandrolone is approximately 6 to 8 days.
Nandrolone also exhibits progestogenic activity, which distinguishes it pharmacologically from testosterone and contributes to some of its characteristic effects and side effect profile. This progestogenic activity is relevant to the compound's effects on mood and sexual function in some users.
These properties explain why nandrolone decanoate is encountered both in medically supervised settings for specific anemia indications and in non-medical bodybuilding contexts where a long-acting injectable is preferred.
Nandrolone decanoate releases more gradually than short-acting esters such as nandrolone phenylpropionate. Its release characteristics support less frequent injection schedules compared to NPP, which is typically administered more often. The 500 mg/mL concentration of Deca 500 mg means that 1 mL provides 500 mg of nandrolone decanoate, allowing for lower injection volumes at equivalent doses.
Dragon Pharma offers several nandrolone-based injectables at different concentrations and release profiles. The standard Deca 300 provides 300 mg/mL nandrolone decanoate for users who prefer a moderate concentration, while Deca 500 mg represents the highest-concentration single-ester nandrolone option in the line.
For those seeking a combined nandrolone and testosterone preparation, Deca 200/Test E offers both compounds in a single formulation. Dragon Pharma also provides Deca 200/NPP 150, which combines nandrolone decanoate and phenylpropionate for a different release profile. Testosterone-based injectables such as Cypionate 250 are commonly referenced as base compounds alongside nandrolone in non-medical bulking cycles.
The information below is provided for educational reference only. Nandrolone decanoate is a prescription medication; medical use requires appropriate diagnosis, clinical supervision and ongoing monitoring. Non-medical use falls outside approved indications.
In medically supervised use for anemia of renal insufficiency, nandrolone decanoate is dosed at 100 to 200 mg per week in men and 50 to 100 mg per week in women. In non-medical bodybuilding settings, nandrolone decanoate is commonly referenced in the range of 200–400 mg per week for general use, with experienced users sometimes referencing higher amounts. Because of the 500 mg/mL concentration of Deca 500 mg, even 1 mL per week provides a substantial dose, and users typically require smaller injection volumes than with lower-concentration products.
| Use Case | Common Reference Range | Injection Frequency |
|---|---|---|
| Medical (anemia of renal insufficiency) | 100–200 mg / week (men) | Per prescriber instructions |
| Bodybuilding (non-medical) | 200–400 mg / week | Once or twice weekly |
| Advanced users (non-medical) | Up to 600 mg / week referenced | Split doses may be preferred |
In non-medical bodybuilding contexts, nandrolone decanoate is frequently referenced alongside a testosterone base compound. Dragon Pharma's Cypionate 250 or Enantat 250 are commonly mentioned in this context. Nandrolone is also sometimes combined with oral compounds during bulking cycles.
Nandrolone decanoate has a long detection time and can suppress endogenous testosterone production. The 500 mg/mL concentration of Deca 500 mg means that users should carefully calculate injection volumes to achieve their intended dose, particularly if they are accustomed to lower-concentration products. Cycle structure, duration, and recovery considerations should account for these characteristics.
Nandrolone decanoate can cause suppression of natural testosterone production, which may lead to sexual dysfunction if not addressed. Some users reference prolactin management with agents such as Caber in non-medical contexts, particularly when nandrolone is used at higher amounts. Nandrolone is known to suppress gonadotropic functions of the pituitary and may exert a direct effect on the testis.
Nandrolone is not a 17-alpha-alkylated oral steroid and therefore is not considered hepatotoxic in the same manner as oral C17-alpha-alkylated compounds. However, it can negatively affect lipid profiles, with documented increases in low-density lipoproteins and decreases in high-density lipoproteins. Blood pressure should also be monitored.
After completing a cycle that includes Deca 500 mg, post-cycle therapy is commonly recommended in non-medical contexts to help restore endogenous testosterone production. Agents such as Clomid or Nolvadex are frequently referenced for this purpose.
Because nandrolone decanoate has a long half-life, some sources suggest allowing additional time before beginning PCT compared to shorter-acting compounds. Bloodwork and, where possible, medical guidance can help inform recovery strategy.
Dosing strategies, support compounds and recovery protocols should be adjusted based on experience level and bloodwork where possible. The information above is for educational reference and does not constitute medical advice.
Nandrolone decanoate is a prescription anabolic steroid that can affect hormonal, cardiovascular, hepatic and reproductive function. Medical use requires appropriate diagnosis, clinical supervision and ongoing monitoring.
Nandrolone decanoate is indicated for the management of anemia of renal insufficiency. It has not been shown to be safe and effective for the enhancement of athletic performance, and the FDA label explicitly states it should not be used for such purpose.
Anabolic steroids in general have been associated with peliosis hepatis, a condition in which liver and sometimes splenic tissue is replaced with blood-filled cysts, as well as liver cell tumors. These conditions may be life-threatening and are often not recognized until serious complications develop.
Use of nandrolone decanoate for bodybuilding or performance enhancement falls outside approved medical indications. Higher-than-physiologic exposure can increase the risk of serious adverse effects including cardiovascular, hepatic and endocrine complications. The 500 mg/mL concentration of Deca 500 mg means that errors in dosing could result in significantly higher exposure than intended.
Nandrolone decanoate can suppress gonadotropic functions of the pituitary and may exert direct effects on the testis, leading to reduced sperm production and testicular atrophy. Sexual dysfunction is a recognized risk, particularly without appropriate management.
Anabolic steroids including nandrolone have been reported to increase low-density lipoproteins and decrease high-density lipoproteins. These changes may have a serious impact on the risk of atherosclerosis and coronary artery disease.
Other potential effects include fluid retention, acne, and changes in prostate-related symptoms. In women, virilization signs such as deepening of the voice, hirsutism, and clitoromegaly may occur and can be irreversible if the drug is continued after symptoms appear. Edema may occur occasionally with or without congestive heart failure, and caution is required in administering these agents to patients with cardiac, renal or hepatic disease.
Nandrolone decanoate is contraindicated in certain circumstances. Caution is required in administering anabolic steroids to patients with cardiac, renal or hepatic disease. Cholestatic jaundice has been associated with therapeutic use of anabolic and androgenic steroids.
Existing cardiovascular disease, liver or kidney impairment, prostate conditions, and other medical conditions should be discussed with a qualified healthcare professional before nandrolone decanoate is considered.
Medically supervised nandrolone decanoate therapy typically involves periodic laboratory monitoring. Hemoglobin and hematocrit should be checked periodically for polycythemia in patients receiving high doses. Serum lipids and high-density lipoprotein cholesterol should also be determined periodically.
For any anabolic steroid therapy, liver function tests may be obtained periodically. Laboratory testing of the product itself, if available, is separate from clinical monitoring of the person using the medication.

Answers to common questions about Deca 500 mg, nandrolone decanoate, release characteristics, product strength and usage considerations.
Deca 500 mg contains nandrolone decanoate, which is medically indicated for the management of anemia of renal insufficiency. In non-medical bodybuilding settings, Deca 500 mg is commonly referenced for muscle mass gains, strength, and joint comfort during bulking cycles, though such use falls outside approved medical indications.
Because of its long-acting decanoate ester, nandrolone decanoate is typically referenced as being administered once or twice weekly in non-medical contexts. In medically supervised therapy, injection frequency is individualized by a clinician.
Nandrolone decanoate is a long-acting anabolic steroid that binds to androgen receptors and promotes anabolic activity in muscle tissue. It differs from testosterone by lacking a carbon-19 methyl group, contributing to a relatively lower androgenic ratio.
In medical practice, it is used for specific clinical indications including anemia of renal insufficiency. Nandrolone also exhibits progestogenic activity, which distinguishes it from testosterone pharmacologically.
Nandrolone decanoate is a long-acting preparation, so its effects are not expected to appear immediately. The time required to notice changes depends on the individual, the specific context of use, and other factors.
Its decanoate ester provides a slower and more prolonged release profile than shorter-acting nandrolone preparations such as nandrolone phenylpropionate. The elimination half-life of nandrolone is approximately 6 to 8 days.
There is no single compound that is universally best for bulking. Nandrolone decanoate is commonly referenced in bodybuilding contexts for its anabolic properties and joint comfort effects, but individual response and goals vary.
Many non-medical cycles combine nandrolone with a testosterone base such as Cypionate 250 rather than using nandrolone alone.
The primary difference is concentration. Deca 500 mg provides 500 mg of nandrolone decanoate per mL, while Deca 300 provides 300 mg/mL. Higher-concentration products allow for reduced injection volume at equivalent doses but are typically referenced for more experienced users.
Deca 500 mg contains nandrolone decanoate, a long-acting ester, while NPP (nandrolone phenylpropionate) is a shorter-acting ester of the same parent hormone. The primary difference is release rate and injection frequency.
Dragon Pharma offers Deca 200/NPP 150 which combines both esters for a different release profile.
A milligram amount cannot be classified as appropriate or excessive without considering the specific context, individual response, and other factors. In non-medical bodybuilding contexts, nandrolone decanoate is commonly referenced in the 200–400 mg per week range, with some experienced users referencing up to 600 mg per week. Such use falls outside approved medical indications.
It is also important to distinguish a dose in milligrams from a product's concentration in mg/mL. Deca 500 mg is labeled at 500 mg/mL; that concentration does not by itself specify how much should be administered. The high concentration means even small volumes deliver substantial doses.
Deca 500 mg is labeled at 500 mg of nandrolone decanoate per mL. It is supplied in a 10 mL vial, giving 5,000 mg of total labeled nandrolone decanoate content per vial.
Because of its high 500 mg/mL concentration, Deca 500 mg is typically referenced in contexts involving experienced users who are familiar with nandrolone decanoate and its effects. The concentration allows for lower injection volumes at equivalent doses compared to standard 200 mg/mL or 300 mg/mL products.
In non-medical settings, the compound is commonly discussed alongside a testosterone base such as Cypionate 250 to help manage the suppression of endogenous testosterone production.
Deca 500 mg uses MCT oil as its carrier. The oil base is designed to support the high 500 mg/mL concentration of nandrolone decanoate in a stable injectable formulation.
