Deca Durabolin: All Benefits & Side Effects

By Mark / a few months ago

Welcome to our review article all about deca durabolin! Before we get into the benefits and side effects of this performance enhancing supplement, let’s first discuss what deca durabolin actually is.

What is Deca Durabolin?

Deca Durabolin, styled as Deca-Durabolin, is the brand name of nandrolone, which is also referred to as 19-nortestosterone.

The androgen and anabolic steroid is used in its ester form.

Deca Durabolin is the brand name of nandrolone decanoate and Durabolin is the brand name of nandrolone phenylpropionate.

Nandrolone in its ester form is used to treat anemia, osteoporosis, wasting syndrome or cachexia and breast cancer.

Nandrolone has to be administered as an injection. It is an intramuscular injection and the steroid is not much active and has low bioavailability when taken by mouth.

History of Deca Durabolin

Nandrolone was first described in its ester form and subsequently introduced in 1950s.

It was only meant for medical use back then. Deca Durabolin continues to remain one of the most widely available and used androgen and anabolic steroids in the world.

During the initial medical use and clinical studies, nandrolone was found to be effective at improving performance and enhancing the physique.

This led to the use of this ester as a performance enhancer. Deca Durabolin is presently sold as an injection. There are alternatives wherein you can get oral supplements.

Nandrolone in its ester form is basically synthesized. It was first used in the form of nandrolone phenylpropionate.

Since its first use in 1959, many variants have been developed, most notably nandrolone decanoate that was synthesized in 1962 and subsequently there have been many esters.

Nandrolone is banned by the anti doping agencies around the world and international sports federations.

Deca Durabolin has many generic names. Nandrolone and 19-Nortestosterone are most common.

Other names include 10-Nortestosterone, Estrenolone or Oestrenolone, Estr-4-en-17β-ol-3-one, 19-Norandrost-4-en-17β-ol-3-one, Nortestrionate or Nortestonate, Norandrostenolone and SG-4341.

The esters are available as injections, eye drops and oral supplements.

Deca Durabolin is listed in Schedule III in the United States, Schedule IV in Canada and Class C in the United Kingdom.

The bioavailability of nandrolone is highest when taken as an intramuscular injection and quite low but moderately effect when taken orally.

The drug is metabolized by the liver, leading to several metabolites including 5α-Dihydronandrolone, 19-Noretiocholanolone and 19-Norandrosterone.

The half life of nandrolone is around four hours when taken orally. The half life is increased to as many as twelve days when it is administered as an intramuscular injection.

The chemical formula of nandrolone is C18H26O2 and its molar mass is 274.404 g/mol.

Benefits of Deca Durabolin

There are medical and nonmedical benefits of Deca Durabolin.

The intramuscular injections are almost always used in clinical settings. The esters can promote growth of muscle, stimulate appetite and increase the production of red blood cells.

There is evidence that the drug can also increase bone density. The drug has been clinically studied and found to be effective at curing anemia and regulating symptoms of osteoporosis.

It can provide substantial relief from chronic skeletal and joint conditions.

The drug is used in the treatment of breast cancer but it is not an outright cure or the main component of the medical remedies.

Nandrolone is used for performance enhancement by bodybuilders, competitive or professional athletes, power lifters and fitness enthusiasts.

The effects of the supplement are somewhat similar to those of SARMs. The performance enhancer can boost energy.

It stimulates appetite and hence makes better use of available calories from the food consumed.

The supplement can trigger better development of lean and healthy mass.

It does not contribute to fat gain.

People who take the supplement regularly experience much greater endurance levels or stamina, which helps them to work out harder, stronger and longer.

Deca Durabolin can be used in the bulking up phase by bodybuilders and fitness enthusiasts.

Power lifters find the supplement extremely useful as they often experience a period of stagnation after sufficient gain in muscles.

The supplement can break that stagnation and further improve the development of lean mass.

Bodybuilders also use the supplement during the cutting cycle, usually by stacking it with others.

The supplement is safe enough to be stacked with other steroids or esters. However, only complementing esters should be stacked.

It is quite possible some steroids will interact with one another and might negate the expected development.

Side Effects of Deca Durabolin

Women may experience masculinization and the common symptoms are changes to voice, acne, excessive hair growth and particularly on the face, changes in libido and sexual desire.

Men usually do not worry about masculinization symptoms.

However, men do experience some potent anabolic effects and mild androgenic effects.

These can lead to suppression of some hormones. Overdosing with Deca Durabolin can cause temporary erectile dysfunction.

Stopping the abuse or overdose will remedy erectile dysfunction. Substance abuse can lead to cardiovascular damage.

The supplement does lead to reducing level of luteinizing hormone and this can have a negative effect if there is prolonged abuse.

Deca Durabolin may cause fluid retention in tissues, increased hemoglobin, nausea, insomnia, itching sensations, changes in lipid profile and blood test results may be unusual, there could be changes to liver functions and excessive abuse can lead to changes in the anatomy of the liver.

Women may experience an enlarged clitoris. These side effects are quite severe but they are not common.

Also, stringent adherence to dosage and course instructions will ensure none of these side effects come to pass.

It is always better to use such supplements moderately and over a due course of time.

Ingredients and Dosage of Deca Durabolin

The main active ingredient in Deca Durabolin is nandrolene.

The standard dosage is 2mg per pound of lean body mass per week.

Hence, if you lean body mass is a hundred and fifty pounds, then the weekly dosage for you will be 300mg.

This should be spread out evenly every day if you want a daily dose. Lean body mass is not the bodyweight.

It is the weight of the lean muscles in the body. This means the total bodyweight should be reduced by the total content of fat.

You must find out how much body fat you have to calculate the lean body mass.

Price of Deca Durabolin

Unfortunately deca durabolin is currently a schedule III controlled substance in the USA, and hence using it for bodybuilding or non-medical purposes is illegal. 

This means that if you come across deca durabolin for sale, chances are it’s being sold on the black market and/or might be a dodgy knock off of the real substance.

As such, we recommend using a safe and legal alternative – Crazy Bulk’s Decaduro supplement is our top pick for a legal alternative that gives you the same strength and endurance without the risk.

Customer Reviews of Deca Durabolin

Most people who have taken Deca Durabolin report positive impact on energy and endurance.

There is substantial effect on bulking up and through the cutting cycle.

However, more people experience better results when Deca Durabolin is stacked with other and potentially more powerful steroids.

Deca Durabolin is not amongst the most potent steroids.

This also means there are fewer risks associated with the supplement. The more potent a steroid, the higher is the likelihood of severe side effects.

Deca Durabolin can be taken by women but not when pregnant or while breastfeeding.

The supplement works best for men. Most women do not want to deal with the symptoms of masculinization.

Although the symptoms are transient and they do not last after one has stopped taking the supplement, the bulking or cutting cycle can become quite troublesome with plenty of visible side effects.

It is futile to take the supplement without having a bulking and cutting cycle. The effects are not as profound.


Deca Durabolin promises to give you the strength and muscle mass of your dreams. It promotes growth of lean mass in the body and can reduce the overall body fat.

It increases strength and enhances stamina or endurance. It can also support protein synthesis and boosts level of testosterone.

However, unfortunately it is also a schedule III controlled substance in the USA. This means that taking it for recreational uses is illegal. 

As such, I don’t recommend taking deca durabolin. It’s not worth risking your health over, particularly since any deco durabolin you come across is likely to come from the black market, or be synthesised in unregulated environments. 

I recommend Crazy Bulk’s DecaDuro instead – It’s my favorite safe and legal alternative to Deca Durabolin that gives me the same level of energy, strength and endurance without the risk.
