Nandrolone Decanoate is also known as Deca Durabolin. This is an anabolic steroid that enhances muscle growth and muscle bulk. Deca Durabolin is made up of slow decanoate ester attachedwith Nandrolone steroid hormone.
Structure and function
Deca Durabolin is a 19-nortestosterone anabolic androgenic steroid. The molecular chain lacks a carbon atom at the 19thposition. The Nandrolone base is attached to a large decanoate ester which slows down the release of the ester.
Nadrolone Decanoate is mainly used to increase muscle mass which it accomplishes by increasing the haemoglobin level, red blood cell count and increasing nitrogen retention significantly. The steroid acts slowly due to the massive Decanoate ester which imparts a half life of 15 days to Nandrolone. Nandrolone Decanoate enhances the mineral content of the bones and also promotes the synthesis of collagen fibres which provides joint relief during strenuous physical activities.
Uses
Nandrolone Decanoate increases the density of the muscles in about two weeks. It also decreases water retention in the body. The increased nitrogen retention results in stronger and bigger muscles because nitrogen is a major component of amino acids which form protein chains. Proteins, as we know, are required to build muscles. It is a great drug to shed weight and maintain lean muscle mass. Bodybuilders and athletes who require a solid and healthy body devoid of fat during the off season utilize this drug. The effect of slow decanoate ester attached with Nandrolone hormone is slow but the final results are worth the patience. 
 
The drug is also useful to treat muscle wasting, combating fatigue and geriatric weakness. It has been found useful for anemic patients. The ability of the steroid to promote collagen synthesis and increase the bone mineral content makes it suitable to treat osteoporosis. Deca Durabolin is also used to treat some harmful effects of HIV.
Dosage
One tablet needs to be consumed two to three times a day at mealtimes. For improving performance, 200mg per week is the minimum dose while for advanced performance the dose is 400mg per week. Joint relief can be achieved by a dose of 100mg per week while for therapeutic purposes, 100mg every 10-14 days will suffice.
The dose should never exceed 600mg with the highest limit being 400-500mg.
Side effects
Deca Durabolin does not have any androgenic effects. This means that it can be safely used by female athletes without the fear of developing secondary male characteristics.The drug is free from side effects such as erectile dysfunction, acne, baldness, bad moods, clitoris problems, decrease in the size of testis and development of breasts in males.
Deca Durabolin can have a detrimental effect on the cholesterol level. The ratio between the High Density Lipoproteins and Low Density Lipoproteins can also be adversely affected. HDL is mostly affected by Deca Durabolin though to a lesser degree when compared to other oral steroids. In order to combat this and protect the cardiovascular system, a diet rich in omega fatty acids and regular exercise become essential.
