Novo-pharm Deca Durabolin - Nandrolone Decanoate General Description

Nandrolone decanoate (Deca, Deca-Durabolin) is an anabolic steroid drug developed as an injectable solution. Nandrolone is 19-nortestosterone's chemical name. Due to prolonged and severe physical activity or childbirth, it can be naturally developed in the human body. Its concentration, however, is extremely small in such situations – a few nanograms per ml of urine. Deca entered the market in 1972 and became popular due to its low androgenic index and major anabolic effects. 

The steroid drug's properties are as follows:

• the anabolic effect is 150% of testosterone;
• the androgenic action is 30% of testosterone;
• the propensity to convert into estrogen is low;
• toxic impact on the liver is insignificant;
• the duration of activity is 15 days (half-life is 7 days);
• the detection period for doping testing is up to 18 months;
• suppression of the functioning of the hypothalamic–pituitary–gonadal axis is high due to the progestin nature of the substance.

The presence of a carbon atom in the 19th position differs its structure from testosterone, which makes it similar to progestin. Because nandrolone exhibits a slight androgenic effect, there are many undesirable reactions due to the co-relation with progestin receptors.

Novo-pharm Deca Durabolin Benefits

Due to its long detection times, competing athletes avoid nandrolone, but usually athletes use the steroid to achieve various positive effects:

• Huge increases in muscle mass. With minimal losses, a single steroid cycle can yield 8 kg of muscle mass.
• Stimulated collagen synthesis leads to strengthened bone tissue and ligaments. The drug is often used in treatment of osteoporosis patients.
• Stimulated production of joint fluid that enhances joint mobility.
• Improved immune system. Nandrolone is used in treating AIDS in medicine.
• An increase in the amount of red blood cells. Deca improves the transportation of oxygen to muscle tissue, improving stamina.

Nandrolone turns into a rather mild androgen called dihydronandrolone with the aid of 5α-reductase. It has almost no effect on the body and causes no unwanted effects. However, a low level of androgens in the blood can lead to a decrease in sexual activity during the injection cycle.

Novo-pharm Deca Durabolin Possible Side Effects

Nandrolone's low risk of adverse reactions is a characteristic feature of the drug. Athletes DO NOT exhibit hair loss, acne, or excessive hair growth throughout the body due to the low androgenic index. Such adverse reactions can occur if users exceed the recommended doses multiple times. The steroid can cause undesirable reactions rhinitis (nasal stuffiness), headaches, back pain, skin rash, hypertension, stomach-ache, bouts of irritation, depressed mood.

Novo-pharm Nandrolone decanoate is characterized by its low propensity to convert into estrogens (this process takes place without any aromatase influence); research has shown that this effect is 5 times lower than that of testosterone. The peak conversion is observed in liver cells, whereas there is no major conversion in the fat deposits. Deca-Durabolin does not cause such aromatization effects as gynecomastia, swelling, fluid accumulation in the muscles that may occur in cases of high dosages. The steroid produces significant progestin activity, leading to flaccid erection, sexual vigor suppression, and symptoms of gynecomastia. 

Patients can eliminate the anabolic drug's progestin activity by using Bromocriptine (used starting from the cycle's 2nd week up to 2-3 weeks after completion) or Cabergoline – the second drug is preferable. During the steroid cycle (and beyond), these drugs increase sexual vigor, stimulate orgasms, and reduce the duration of refraction between sexual acts. 

Novo-pharm Clomid antiestrogen is used to normalize the hypothalamus-pituitary-testis axis function. Nandrolone's combined cycle with Winstrol suppresses progestin production. Due to its property of increasing progestin production, which can contribute to prolactin gynecomastia, tamoxifen may not be used during PCT after use of Deca. Chorion gonadotrophic hormone can be combined with testosterone boosters to restore the production of natural male sex hormone.

Novo-pharm Deca Durabolin Administration and Dosage

Novo-pharm Deca-Durabolin's injection period is quite long and lasts 10 weeks. The recommended weekly dose is 200-600 mg. Injections must be performed once a week intramuscularly. Cycles that last over 2 months must be supplemented with chorion gonadotrophic hormone (injections start from week 4-5). HCG is used during post-cycle therapy after the end of the cycle.

Novo-pharm Deca Durabolin Combined Cycles

The steroid can be used solo and with other anabolic-androgenic medications in mixed cycles. Deca is best combined with testosterone because it minimizes libido suppression, natural hormone concentration inhibition, and slow steroid action. Mixed cycles often see Winstrol, Sustanon and Methandrostenolone used with high efficiency. 

Here are some regimens of the combined cycles:

• Nandrolone decanoate + testosterone/Sustanon. Testosterone dosage should be twice as high as nandrolone – 500 mg of testosterone per week and 100-300 mg of Deca. Cabergoline (0.25 mg every 4 days) and aromatase inhibitors (0.5 mg every other day of anastrozole) can be used as well.
• Nandrolone decanoate + Dianabol. Nandrolone at 200 mg a day (400 mg for the first week) and 20 mg of Methandrostenolone. Cabergoline is applied every 4 days at 0.25 mg from the second day.
• Nandrolone decanoate + Winstrol. 200 mg per day of nandrolone and 30 mg per day of Winstrol.

It is important to use combined cycles with Cabergoline. After the final injection, post-cycle therapy should start in 3 weeks.
