Нандроло́на деканоа́т (МНН) — лекарственное средство, анаболический стероид пролонгированного действия (эфирная деканоат-группа на рисунке не изображена). Нандролона деканоат зарегистрирован в России как лекарственный препарат под торговой маркой "Ретаболил", в других странах также выпускается в форме фенилпропионата.


Nandrolone Decanoate is known to increase hemoglobin and red cell mass. With the development of recombinant human erythropoietin, nandrolone decanoate use in anemia associated with chronic renal failure has declined. It has also been the subject of drug misuse and abuse, often producing adverse effects such as changes in libido, hepatotoxicity, increased risk of cardiovascular disease, and antisocial behavior. Some of the masculinizing effects in women can be irreversible. Nandrolone decanoate was approved by the FDA in 1983 and became a controlled substance in 1991.
Bodybuilders' body composition: effect of nandrolone decanoate.
INTRODUCTION:
The use of androgenic-anabolic steroids (AAS) among bodybuilders to increase muscle mass is widespread. Nandrolone decanoate (ND) is one of the most popular misused AAS, although the effects on body composition are equivocal. Therefore, the purpose of this study was to determine the effect of ND on body composition in male bodybuilders, with special reference to muscle mass alterations.
METHODS:
Using a randomized "double-blind" "placebo-controlled" design, 16 experienced male bodybuilders (age: 19-44 yr) either received ND (200 mg.wk(-1), intramuscularly) or placebo for 8 wk. Body composition was assessed using the four-component model, combining results from underwater weighing, dual-energy x-ray absorptiometry (DXA), and deuterium dilution. Total bone mineral content and density were measured using DXA. Water compartments (extracellular water [ECW] and intracellular water [ICW]) were determined using deuterium dilution and bromide dilution.
RESULTS:
ND administration resulted in significant increments of body mass (+2.2 kg), fat-free mass (FFM: +2.6 kg), and total body water (+1.4 kg). No significant changes in fat mass, percentage fat, ECW, ICW, ECW/ICW ratio, hydration of the FFM, and on bone mineral measurements were observed.
CONCLUSIONS:
The results show that the administration of 200 mg.wk(-1) of ND (intramuscularly) for 8 wk significantly increased body mass and FFM, whereas fat mass, bone mineral content, bone mineral density, and the hydration of the FFM remained unaffected. These data indicate that the changes can be attributed to an increase of muscle mass.
