What is Nandrolone Decanoate / DECA-DURABOLIN ?

steroid use, dosage and side effects of Deca Durabolin steroid

The active chemical substance: Nandrolone Decanoate

Brand names : Anabolin , Deca-Dubol , Deca-Durabolin , Decanofort , Retabolil , Deca-Durabol , Sterobolin ,Extrabolin.

Deca-Durabolin is the most widespread and most commonly used injectable steroid.


Deca's large popularity can be attributed to its numerous possible applications and, for its mostly positive results.

Deca-Durabolin causes the muscle cell to store more nitrogen than it releases so that a positive nitrogen balance is achieved. A positive nitrogen balance is synonymous with muscle growth since the muscle cell, in this phase, assimilates (accumulates) a larger amount of pro-tein than usual. The same manufacturer, however, points out on the package insert that a positive nitrogen balance and the protein building effect that accompany it will occur only if enough calories and proteins are supplied.One should know this since, otherwise, satisfying results with Deca cannot be obtained.


The highly anabolic effect of Deca-Durabolin is linked to a moderately androgenic component, so that a good gain in muscle mass and strength is obtained. At the same time, most athletes notice considerable water retention which, no doubt, is not as distinct as that with injectable testosterones but which in high doses can also cause a smooth and watery appearance.

Since Deca also stores more water in the connective tissues, it can temporarily case or even cure existing pain in joints. This is especially good for those athletes who complain about pain in the shoulder, elbow, and knee; they can often enjoy pain-free workouts during treatment with Deca-Durabolin. Athletes use Deca, depending on their needs, for muscle buildup and in preparation for a competition.


Deca is suitable, even above average, to develop muscle mass since it promotes the protein synthesis and simultaneously leads to water retention. The optimal dose for this purpose lies between 200 and 600 mg/week. Scientific research has shown that best results can be obtained by the intake of 2-mg/pound body weight. Those who take a dose of less than 200 mg/week will usually feel only a very light anabolic effect which, however, increases with a higher dosage.


Most male athletes experience good re-sults by taking 400 mg/week. Steroid novices usually need only 200 mg/week. Deca works very well for muscle buildup when combined with Dianabol and Testosterone.

The famous Dianabol/ Deca stack results in a a fast and strong gain in muscle mass. Most athletes usually take 15-40 mg Dianabol/day and 200-400 mg Deca/week. Even faster results can be achieved with 400 mg Deca/week and 500 mg 5ustanon 250/week. Athletes report an enormous gain in strength and muscle mass when taking 400 mg Deca/week, 500 mg Sustanon 250/week, and 30 mg Dianabol/day. Deca is a good basic steroid which, for muscle buildup, can be combined with many other steroids.

A conversion into estrogen, that means an aromatizing process, is possible with Deca-Durabolin but occurs at a lower rate than ex: testosterone. During competitions with doping tests Deca must not be taken since the metabo-lites in the body can be proven in a urine analysis up to 18 months later. The risk of potential water retention and aromatizing to estrogen can be successfully prevented by combining the use of Proviron with Nolvadex. A preparatory stack often observed in competing athletes includes 400 mg/week Deca-Durabolin, 50 mg/day Winstrol, 228 mg/week Parabolan, and 25 mg/day Oxandrolone.

Deca Durabolin steroid  side effects :

Although the side effects with Deca are relatively low with dosages of 400 mg/week, androgenic-caused side effects can occur. Most problems manifest themselves in high blood pressure and a pro-longed time for blood clotting, which can cause frequent nasal bleed-ing and prolonged bleeding of cuts, as well as increased production of the sebaceous gland and occasional acne. Some athletes also report headaches and sexual overstimulation.

When very high dos-ages are taken over a prolonged period, spermatogenesis can be inhibited in men, i.e. the testes produce less testosterone. The reason is that Deca-Durabolin, like almost all steroids, inhibits the release of gonadotropins from the hypophysis.

Women with a dosage of up to 100 mg/week usually experience no major problems with Deca. At higher dosages androgenic-caused virilization symptoms can occur, including deep voice (irreversible), increased growth of body hair, acne, increased libido, and possibly clitorihypertrophy.

Women who experience disturbance even at a weekly dose of only 50 mg/week of Deca-Durabolin, are often better off taking the earlier mentioned and faster-acting Durabolin. Unlike the long-acting Deca, when Durabolin is administered once or twice weekly in a dosage of 50 mg, no concentration of undesired amounts of androgens occur. Since most female athletes get on well with Deca-Durabolin a dose of Deca 50 mg +/week is usually combined with Oxandrolone 10 mg +/day Both compounds, when taken in a low dosage, are only slightly androgenic so that masculinizing side effects only rarely occur.

Deca, through its increased protein synthesis, also leads to a net muscle gain and Oxandrolone, based on the increased phosphocreatine synthesis, leads to a measurable strength gain with very low water retention. Other variations of administration used by female athletes are Deca and Winstrol tablets, as well as Deca and Primobolan S-tablets.

A great disadvantage of Deca-Durabolin is its high price. In the U.S. a 50 mg ampule costs approx. $10

Deca-Durabolin in strengths of 200 mg/2 ml ampules; usually cost around $30 per ampule.Because of its great popularity and the high demand that goes along with it, there are many fakes of Deca-Durabolin

This profile talks about deca durabolin and if you are a person who has tried a safe way to gain muscle we know that deca could be a good choice for the gym trainer who spends hours on end preparing workouts and nutrition for a better body . Well back to deca there are many kinds of deca and from expirence and talking to other body builders who have used deca it seems like the veterinary products are garbage and only leave u with the side effects of contaminated anabolics steroids. If u could get a prescription for deca & you can if u do your home work . It will pay off in The long run . If u could get the organon product at 100mg per amp, that would be your best bet ,but even that [no spam please]er beware there are fakes floating around so investigate your source last but not least if u take more deca make sure u take at least 200mg it testosterone added to prevent a problem called DECA DICK, I'd say a dose of 100mg helps the body- relives sore joints after about 4weeks cycle should last 12weks
