Benefits of Deca Durabolin for Bodybuilders

Nandrolone-Decanoate or Deca Durabolin, or just Deca for short, is an anabolic steroid that bodybuilders use to help them bulk up and cut fat. Deca is well-known in the bodybuilding world and in this article, we discuss the benefits of Deca Durabolin for bodybuilders.

What is Deca?

Deca has been one of the most widely used anabolic steroids among bodybuilders, it was developed in 1960 and is a derivative of the steroidal hormone Nandrolone. Deca was sold commercially in 1962 under the name Deca Durabolin and is also known as Deca Decanoate.

Benefits of Deca Durabolin for Bodybuilders

Deca besides being used by bodybuilders has been used to treat patients suffering from muscle wasting diseases and to help elderly patients who suffer from symptoms of anemia, weakness, and fatigue. Deca Durabolin has also been used to treat breast cancer. Other uses from Deca Durabolin include:

  • Treatment of ulcers
  • Pituitary gland deficiency (Dwarfism)
  • Treat children suffering from slow development
  • Patients suffering HIV anemia
  • Osteoporosis
  • Anti-aging effects

In the bodybuilding world, Deca is used as a bulking agent, but many bodybuilders choose to use this anabolic steroid during cutting cycles as well. Let's take a look at some of the benefits of taking Deca.

1. Improves Muscle Protein Synthesis

Muscle Protein Synthesis (MPS) is a naturally occurring reaction to exercise and is typically balanced by Muscle Protein Breakdown (MPB). In order for the human body to pack on muscle, the balance between MPS and MPB must tip in favor of MPS. What this means is that you will need to increase the ratio of muscle protein synthesis and decrease the ratio of muscle protein breakdown. When they are balanced, you remain the same. If MPB is too great (catabolic) then you lose muscle.

So, once you exercise, the process causes your body to pay attention to MPS and MPB. Without eating a ton of food, then MPB increase. If you eat a ton of food other issues occur – we gain weight, fat gain, etc. To increase muscle protein synthesis, you need testosterone or a form of testosterone, such as Deca Durabolin for that increase to happen. That increase in MPS is one of the reasons why Deca is so popular.

The other thing to consider is that once you exercise the after effects last as long as 48 hours. What that means is that for upwards of 48 hours (24-48 hours depending on the intensity of the workout) your body needs to have adequate resources for muscle protein synthesis. This is a time when your body is deciding if it should repair a muscle cell or replace it. With protein synthesis, your body builds bigger muscle cells.

Deca helps your body to tip the MPS scale so that your muscles can adequately use protein and it does so without requiring that you increase your caloric intake. The up benefit of this is that your muscles recover faster. So, in addition to improving protein synthesis, it helps your body recover quickly so that muscle cell damage is repaired quickly and new cells are replaced faster.

Improves Strength and Duration

The other big thing that Deca Durabolin does for bodybuilders is that it helps to power bigger workouts. The secret is listed above. Deca helps the muscles recover their energy faster. What that means is that as a bodybuilder you can workout more often with the same results.

Does Deca make you physically able to lift more? No… or not exactly. There is a boost in energy levels which you can utilize to lift more, but the real benefit is that you can lift more weights more often and that builds up your muscles which is how Deca helps people to gain strength.

That is an important fact. Often, bodybuilders plateau because of consistent training routines, and training 5-6 days a week.

Taking Deca makes it easier to gain muscle. plus their strength increases and they are able to push past those plateaus.

3. Lower Aromatizing Properties

In comparison to testosterone and many other injectable anabolic steroids, Deca does take longer to convert from synthetic testosterone into estrogen. It will convert to estrogen, it just takes longer. That is a boon to bodybuilders because it slows down the aromatizing process and allows people to use Deca longer.

It is important to point out that Deca still carries many of the same side effects as other anabolic steroids and the risk is just as great. The deal is that the process is slower, and people can ride the wave longer (in most cases) than they can with other alternatives

You may hear that Deca Durabolin is a kinder steroid. It is and it isn't. It does not produce all of the side effects of other anabolic steroids, but it can still cause massive damage to your liver and kidneys.  Other side effects of taking Deca may include:

  • Gynecomastia (Man Boobs)
  • Excess water retention
  • High Blood pressure
  • Increase in LDL Cholesterol

Long-term use of Deca Durabolin has been associated with Leukemia, enlarged prostate and anemia from iron deficiency.


While Deca is still a very popular anabolic steroid, it does have risks, unless you are a professional bodybuilder and competing in the big leagues this is probably an anabolic steroid you should avoid. There are many safe legal Deca alternatives that can deliver the same benefits without having to worry about the side effects.
