DECA/Enhance Physique and Performance


Description of DECA 

DECA is the abbreviated form of Nandrolone decanoate. Nandrolone decanoate is a nandrolone ester, or prodrug of nandrolone. It is an androgenic and anabolic steroid, or agonist of AR, a biological target of androgens, such as testosterone and DHT. Nandrolone decanoate enhances anabolic effects and reduces androgenic effects relative to testosterone. It is considered to be highly anabolic, but less androgenic. Nandrolone Decanoate is used by competitive athletes, bodybuilders and weight lifters for physique and performance enhancement purposes. Bodybuilders build on some form of testosterone and consume it every 8-12 week weight gain cycle. Because according to research: if consumed alone (i.e. without a base), it shuts down the natural production of testosterone by altering the composition of the blood-testis barrier. Nonetheless, nandrolone decanoate is one of the most popular injectable AASs worldwide. Nandrolone is said to be the most popular AAS in bodybuilders and sports. This is in part due to the high ratio of anabolic to androgenic effects of nandrolone and its weak propensity for androgenic and estrogenic side effects.


Function and efficacy

Tonic for protein deficiency, malnutrition, post-operative and chronic wasting disease recovery, etc. Also used for inoperable breast cancer and functional uterine bleeding, uterine fibroids, renal failure. When using adrenocortical hormones for a long time, in order to reduce osteoporosis, this product can be used as appropriate. It can also be used for fractures that are not easy to heal, osteoporosis, etc.


Usage and Dosage

Deep intramuscular injection. The adult dose is 25-50 mg each time, once every 3 weeks. Aplastic anemia: 1~1.5mg/kg each time, once every 1~4 weeks. Pediatric dose: 5-10 mg each time for infants; 10-25 mg each time for children; once every 3 weeks on average. Aplastic anemia: 1~1.5mg/kg each time, once every 1~4 weeks. Reference dose for the elderly: 25 mg each time, once every 3 weeks.



After the oil is injected intramuscularly, a durable depot is formed in the muscle, and Nandrolone Decanoate remains unchanged and is slowly absorbed into the body. Once in circulation, it is converted to Nandrolone, the active form of the drug. Nandrolone decanoate levels rose sharply within 24 to 48 hours after intramuscular injection of nandrolone decanoate, and then dropped steadily to baseline levels in about two to three weeks. Intramuscular nandrolone decanoate bioavailability ranges from 53% to 73%, depending on the injection site, with the highest bioavailability when injected into the gluteal muscle. Like testosterone, nandrolone is highly bound to proteins and is present in the blood in both bound and free fractions. It has a very low affinity for sex hormone binding globulin (SHBG), about 5% of testosterone and 1% of DHT.

The elimination half-life of nandrolone decanoate administered by intramuscular injection is approximately 6 to 12 days. Studies evaluating the duration of nandrolone decanoate by anabolic effects (eg, on nitrogen balance) have found that a single 50 to 100 mg intramuscular injection lasts approximately 18 to 25 days. The combined process of hydrolysis to nandrolone and elimination of nandrolone has a blood half-life of 4.3 hours. Nandrolone and its metabolites are mainly excreted in the urine as conjugates.

Although nandrolone decanoate is usually administered by intramuscular injection, it has been found to be equally effective when administered by subcutaneous injection. The pharmacokinetics of subcutaneous injection of nandrolone decanoate are very similar to those of intramuscular injection. However, subcutaneous injections are considered easier, more convenient, and less painful than intramuscular injections. Also, research shows that in fact most intramuscular injections are actually subcutaneous injections.



1. Patients with liver disease, hypertension, edema, prostate cancer and pregnant women are prohibited.

2. Use with caution in patients with liver and renal insufficiency and congestive heart failure.

3. Store in an airtight place below 10°C with shading.

Other precautions are the same as Nandrolone Phenylpropionate.

4. Long-term use of this product in large quantities can cause water and sodium retention, liver damage, and slight virilization of women.

[Preparation] Injection (oil solution): 10mg(1ml)/piece, 25mg(1ml)/piece, 50mg(1ml)/piece.


Side Effect

The side effects of nandrolone decanoate depend on the dose, duration of treatment, and individual sensitivity. Many common, uncommon and rare side effects have been observed with the recommended doses of the drug. Although less common or severe than many other AASs, the most common side effect of nandrolone decanoate is virilization (masculinization) in women. Uncommon side effects of nandrolone decanoate at recommended doses include fluid retention, inhibition of spermatogenesis, testicular atrophy, and erectile dysfunction. Gynecomastia, increased frequency of penile erections. Increased penis size, clitoral hypertrophy, and increased pubic hair growth in prepubertal boys. Oligomenorrhea, amenorrhea, hyperlipidemia, decreased HDL cholesterol, increased hemoglobin (to abnormally high levels) in women. High blood pressure, nausea, epididymitis, irritable bladder, decreased urine flow. Benign prostatic hyperplasia, priapism, premature epiphysis closure (in children) and acne.
