The Danger Of Using Deca Durabolin (Nandrolone)

Nandrolone decanoate was first described in 1960 and was first used in medicine in 1962. The Organon firm began to produce it and sold it under the brand name of the Deca Durabolin. This name means that this product contains a variety of previously popular Nandrolone – Durabolin (phenylpropionate) with Ester of the ten carbon atoms.

Because of Organon, nandrolone decanoate has become one of the most widely used injectable steroids in the world. It was prescribed for the treatment of many diseases. It was used for the treatment of dystrophy, osteoporosis, breast cancer, malnutrition, severe injuries, anemia and the growth retardation of children. Initially, the drug was produced in a concentration of 50 mg ml, then emerged versions with concentrations of 100 mg ml and 200 mg ml. After 1975, its scope was reduced, but not by much. Deca Durabolin by Organon is widely available in our time. Furthermore, Nandrolone decanoate is produced by a variety of firms under a variety of brand names.

Chemical structure

Nandrolone decanoate – it is a modified form of Nandrolone, in which the decanoate ether is attached to nandrolone through the 17-beta-hydroxy group. Esterified steroids are less polar than the free steroids and are soaked up more slowly from the injection area. Getting into the bloodstream, the ether is cleaved off and the free nandrolone is released into the bloodstream. Esterified steroids have been developed in order to prolong the therapeutic effect after the injection and to inject less frequently compared to injections of free steroids.  Nandrolone decanoate (Deca) was developed to provide a prolonged excretion of nandrolone within 4 weeks after injection.


  • Anabolic activity – 150% of testosterone
  • Androgenic activity – 30% of testosterone
  • Aromatization (conversion into estrogens) – minimal
  • Toxicity to the liver – low
  • Type – injections
  • The duration of action – 15 days
  • Recommended dosage – 200-400 mg per week
  • The detection time – up to 18 months
  • Suppression of the testosterone – average-high (due to the nature of the progestin)


  • Noticeable muscle growth (in one course you can gain up to 8 kg (16 lbs) of muscle mass with a minimal rollback phenomenon)
  • Strengthening of bones (previously was used to treat osteoporosis) and ligaments (stimulates collagen synthesis)
  • Elimination of joint pains, due to increasing of production of synovial fluid (joint lubricant)
  • The increase of red blood cell mass, which improves the oxygen transport
  • Increase of immune protection (applies even to people with AIDS)

Nandrolone (Deca) has a relatively low likelihood of side effects. As a result of low androgenic activity, such side effects as acne, baldness and body hair growth almost never occur. Nevertheless, they are possible, as in the use of any steroid; but in the case of nandrolone, this only happens when the recommended doses are exceeded in several times.

Deca Durabolin has a very low conversion rate to estrogens, research has shown – 5 times lower than testosterone. The highest level of conversion is observed in the liver, while the main place where the transformation takes place (adipose tissue) is still inaccessible to this process. As a consequence, Deca Durabolin has no side effects connected with estrogen (gynecomastia, a buildup of fluid in the body). Estrogenic activity of the drug is manifested only at very high doses.

The aforementioned characteristics explain why Deca Durabolin is one of the most popular anabolic steroids to the present time, including for the men for the purpose of gaining lean muscle. Moreover, it is necessary to add that nandrolone practically does not cause a phenomenon of rollback.

Side effects

It has been observed that Nandrolone is able to bind to progestin receptors (approximately 20% of the injected material), it is connected with the removal of the carbon atom in the 19th position. Almost all of the 19-nor anabolic steroids are showing progestin activity.

In addition, in research retabolil (Deca) caused the following side effects:

  • Headache – 20%
  • Rhinitis (runny nose)- 15%
  • Backache – 15%
  • Rashes – 10%
  • Gynecomastia
  • HPTA shutdown

Besides, during the course sometimes occur the rise of blood pressure, abdominal pain, irritability, headaches, depression and some other complications.

The Natural Alternative To Deca Durabolin

What Is DecaDuro?

DecaDuro is a natural alternative to a steroid called Deca Durabolin.

It’s for people who want the effects of using steroids but without the negative side effects.

It’s made by a company called Crazy Bulk.

They have a good reputation online for producing quality legal steroids that work.

DecaDuro is a supplement for guys who want to build muscle fast and ignite their workouts to make them more intense.

How Does DecaDuro Work?

There’s 3 main things this supplement does.

Let me explain:

  1. Increases Nitrogen This is important for muscle growth because the more nitrogen you retain the more anabolic you remain. When your body is in a state of anabolism you build muscle much faster.
  2. Increases Protein Synthesis This means your muscles will repair and grow faster because proteins are the building blocks of muscle.
  3. Increases Red Blood Cell Count This helps deliver more oxygen to your muscles so you can workout for longer and with more intensity. You’ll get great pumps too.

How To Use DecaDuro To Get Amazing Results

We all have our own strategies when it comes to building muscle and working out.

Here’s what I did:

  • Eat around 1 gram of protein per lb of LBM. So if your lean body mass is 145lbs then you’ll eat 145 grams of protein per day.
  • Eat around 750 calories per day above maintenance.
  • Train hard and lift heavy. I recommend the BodyBeast program
  • Make sure you get a good sleep.
  • Use DecaDuro

That’s what I did to build muscle using DecaDuro.
