Nandrolone decanoate for system suitability European Pharmacopoeia EP Reference Standard 360-70-3
In the present study we imitated the abuse of AASs by administering high doses of the AAS nandrolone decanoate (ND) to rats. Thereafter rats were exposed to an elevated plus-maze and an olfactory social memory test to evaluate their anxiety-like and cognitive behaviour. To reveal whether these emotional and cognitive changes evoked by ND were caused via direct activation of androgenic receptors (ARs) in the brain, the AR antagonist flutamide (FL) was administered intracerebroventricularly (i.c.v.).
- They demonstrated an increase in the activity of SOD and decrease in MDA levels denoting a protective effect against lipid peroxidation and oxidative damage.
- FL has to be hydroxylated into its active metabolite via the cytochrome P-450 enzymes CYP1A1, CYP1B1, and CYP1A2 (Rochat et al., 2001).
- On the other hand, chronic exposure to supraphysiological dose of ND decreased the time to cross the beam in EBW test compared to exercise group.
- Nandrolone is a testosterone analogue with anabolic properties commonly abused worldwide, recently utilized also as therapeutic agent in chronic diseases, cancer included.
- Despite their generally positive results, studies of the effects of aerobic exercise training in the hemodialysis population have not resulted in the widespread adoption of such programs.
Nandrolone Decanoate is one of the Class II anabolic androgenic steroids which quickly spread globally and used clinically and illicitly and composed of 19-nortestosterone-derivates . This review evidences that improper usage and abuse of AASs cause several adverse effects in all body tissues and organs, highlighting the mechanics behind side effects. To sum up, inflammatory cytokines, oxidative stress, protein synthesis alteration, and apoptosis are common mechanisms involved in AAS-related damage.

These structural changes in biomolecules can alter cellular function and processes, and play an important role in a range of common diseases and degenerative conditions . As the liver is the major organ involved in the drug metabolization, and the kidneys are responsible for its excretion, these organs are generally affected by high doses of AAS. On the other hand, the effects of AAS on the heart are well documented by us and others –. As a large body of evidence shows a role of oxidative stress in liver, kidney and heart dysfunction, we investigated if nandrolone decanoate, the most used AAS by bodybuilders and recreational athletes, could interfere in the redox balance of these tissues. Subjects received blinded treatment for 12 weeks, followed by open-label therapy for 12 weeks. Lean body mass and fat (bioelectrical impedance analysis) and weight were measured at baseline and at weeks 6, 12, 18, and 24.
Biochemical assessments of safety (hematologic analyses, liver function tests, and sex hormone measurements) were performed at these same time points. The main findings in this study are that both chronic swimming training and chronic exposure to ND had a significant https://www.tem.co.th/uncategorized/new-study-reveals-optimal-dosage-of-nandrolone-for-3/ influence on behavioral patterns in rats. Also, all three applied protocols were sufficient to induce alterations in the sex hormone profile (Table 1). The data concerning the effects of AASs (including ND) on sex hormone levels are very controversial.

Also, AS have been used for decades by athletes and body builders for the same purpose. On the other hand, many side effects were reported with their illicit abuse . Our research was directed to assess the toxic effects of AS on some biochemical, histopathological parameters of cardiac and skeletal muscles in male albino rats in addition to evaluation of the potential ameliorative effects of Silymarin and fenugreek seeds extract.
The Doctors at Innovative Men’s Clinics can provide nandrolone therapy in addition to your Testosterone treatment. We adhere to a strict protocol for treatment and monitoring to ensure the best possible benefit.

This study was supported by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases (DK-56182).
The typical side-effect of fast increase in weight in ND-treated animals, which was found in the present study, also indicates a suitable dose of nandrolone to study heavy abuse of AASs. However, stimulation of central ARs does not contribute to this effect, since FL injected i.c.v. did not prevent ND-induced increase in weight. Aggression, one of the well known behavioural side-effects of AASs found both in animals (Clark and Barber, 1994; Johansson-Steensland et al., 2002; Long et al., 1996) and humans (Hall et al., 2005; LaBree, 1991; Yesalis and Bahrke, 1995), forced us to exclude two rats from the study. Since nandrolone decanoate has actions similar to endogenous androgens, administration of nandrolone decanoate has the possibility of causing serious disturbances of growth and sexual development if given to young children and causing unwanted adverse effects in women.
Side effects are rare and mostly benign and reversible on cessation of the medication. Physical activity was measured using three-dimensional accelerometers (TriTrac R3D; Professional Products, Inc., Madison, WI) that were worn for 1 wk as described previously (18). Patients were timed while walking 20 ft at their usual pace and as fast as possible. Patients also were timed while walking up one flight of stairs and while rising from a chair five times. Muscle strength during knee extension was tested using a computerized dynamometer (Cybex Inc., Ronkonkoma, NY).
Untreated cells, used as control, were supplemented with vehicle only (ethanol) that never exceeded 0,002% (V/V). For antioxidant treatment, cells were incubated for 72 h with 80 µM nandrolone ± 10 mM N-Acetyl Cysteine (NAC) added 4 h before the analysis. The cellular morphology was observed at inverted optical microscope (Axio Vert A1, Zeiss, Oberkochen, Germany). To evaluate the effect of nandrolone to spheroid formation, 80 μM nandrolone was added to cell suspension when seeded into ultra-low attachment plates and the culture was maintained for 3 days or 7 days.

The anabolic effect on proteins requires a specific diet necessary to maintain a correct nitrogen balance. Unfortunately, hyperproteic diets are often not balanced and excessive proteins are eliminated through urine or converted into fat [39,41]. The aim of this systematic review is to focus on the side effects related to illicit AAS abuse, evaluating findings in the scientific literature, in order to underline the most frequent side effects on AAS abuser’s bodies. Because of the widespread use of nandrolone among professional athletes, the governing bodies of many sports require testing.
