The Effects Of Deca Durabolin

What does Deca/Nandrolone actually do to the body?

Why do people actually use it?

Below are the key benefits as to why bodybuilders and athletes start using Deca;


Protein Synthesis

Deca helps to increase the speed in which we build muscle and also helps to speed up repair time, which allows you to workout more. It does this by improving Protein Synthesis. As we workout, the cells within the muscles are damaged and out body repairs these cells with stronger ones, it is this that is known as Protein Synthesis.


Nitrogen Retention

As we workout our bodies consume nitrogen which is found within the protein. Without this nitrogen, we are unable to effectively build muscle. Deca is used as it helps to improve nitrogen retention, resulting in you being able to increase muscle growth and mass.


Increases Red Blood Cells

We all know how important oxygen is, what else are you going to breath? Did you know that it doesn’t just keep us alive, it also helps to boost your power and strength when you are working out. Red blood cells are needed to help move oxygen around our bodies, Deca Durabolin helps to increase the amount of red blood cells found in our body. Additional benefits of increased oxygen is that your muscles don’t tend to be as tired after a workout, meaning you can lift more and last longer at the gym.

The above are the main effects of Nandrolone on the body, the benefits associated with Deca include;

  • Boost To Muscle Growth

Suppressed Testosterone

Our body produces testosterone naturally, there are certain things we can do to increase and decrease the production. Deca is a synthetic testosterone and this causes your body to stop producing testosterone. If this happens you will tend to see side effects such as;

  • Reduced Libido
  • Erection Problems
  • Muscle Fatigue
  • Reduced Strength
  • Fat Gain
  • Muscle Wastage

To help prevent these effects, many people will supplement Nandrolone with a testosterone booster. When you cycle off Deca, the break should result in your body producing testosterone again naturally.


Cardiovascular Problems

Deca is known for causing water retention which can cause cardiovascular problems. The most common with increased water weight gain is increase blood pressure and this is followed by high cholesterol. If you do have heart conditions already then you should be very careful in taking steroids such as Deca Durabolin. It is possible to reduce these effects by adding supplements that help to reduce estrogen as well as focus on your diet to reduce saturated fats.



One side effect of steroids that many men want to try and avoid is Gynecomastia, or other wise known as man boobs. This is when the breast tissues increase and stimulation of breast tissue growth. It is fairly common for men that use Deca to experience some form of breast growth, unless you use a supplement to help reduce the estrogen in your system.



Deca Durabolin is a steroid that should really only be used by men, this is because of the masculinization side effects. These side effects include the growth of facial hair and deepening of the voice.
