Nandrolone: Package Insert
As a consequence, https://ppid.unp.ac.id/nandrolone-decanoate-unveiling-the-effects-of-this/ has been implicated in relation to doping (especially in sports, where muscle mass and strength are deciding factors) and was banned by the International Olympic Committee Medical Commission in 1974. Recently, several elite athletes have tested positive for 19-norandrosterone (19-NA) and 19-noretiocholanolone (19-NE), two nandrolone metabolites that are used as marker metabolites of use of nandrolone doping. However, the urine levels of these metabolites were often only slightly above the threshold level of 2 ng/ml, and there has been discussion and controversy about whether such borderline levels are valid proof of nandrolone abuse for performance enhancement (13, 14).
- Nandrolone decanoate is an anabolic steroid indicated for the management of the anemia of renal insufficiency by increasing hemoglobin and red cell mass.
- In this case, the Deca dosage remains within the standard recommendations ( mg/week) with testosterone at a higher dosage than the chosen Deca dose.
- Liver NOX2 and NOX4 mRNA levels were unaffected by the treatment, but the activity of these enzymes is not only affected by their mRNA/protein expression, but also by other factors such as protein association and activation by intracellular pathways [10].
- Anabolic steroids include testosterone and lab-grown (synthetic) forms of testosterone.
- Testosterone is a steroid hormone that has an essential role in the development of the male phenotype and the regulation of reproduction of males.
Apoptosis was detected by flow cytometry (Navios, Beckman Coulter, Brea, CA, USA) following staining of cells for Annexin-V-FITC and PI (BD Biosciences), after 72 h of incubation with nandrolone (80 μM). Slowing of cell growth is generally linked to modification of the cell metabolism because of the lower energy needs; this might be a consequence, adapting the cellular bioenergetic to the more quiescent cellular state, or it may cause per se a dampening of cell proliferation. To deepen this aspect, we evaluated the bioenergetic metabolic fluxes in intact cells by Seahorse methodology. As expected, the mitochondrial oxygen consumption rate appeared to be lower in cells treated with nandrolone while the glycolytic flux was unaffected.
Other side effects of Deca-Durabolin
Unlike, their effect on HDL that showed a significant reduction in serum level. Cardiac troponin I (cTnI) is a cardiac enzyme which is released when ether is a damage in the myocytes and considered a sensitive factor of these damages. The levels of this enzyme showed no significant changes in research done on mice treated with silymarin alone [19].
- Oxidative stress could play a role in determining liver damage consequently to AAS abuse by activating androgen receptors that lead to mitochondrial degeneration of hepatic cells.
- In particular, it has been shown that up to 15% of nutritional supplements may indeed contain detectable amounts of nandrolone (or nandrolone precursors and metabolites) (16).
- Adverse events (AEs) and serious adverse events (SAEs) were recorded according to standard methods.
- Results of our study indicate the opposite effects of long-term exercise and supraphysiological doses of AAS on the number of PV immunoreactive neurons in different regions of hippocampus.
- It is administered via intramuscular injection and is metabolized in a similar manner to testosterone, with conversion into 3-norandrosterone by5α-reductase [16].
In our data, the most reported skin lesions were colored patches, acne, and itch disorders. Almaiman and colleagues, in a study conducted on a group of gym athletes who were using a mix of several AASs, reported itching and the emergence of skin patches among other adverse reactions [30]. Similar skin characteristics were highlighted in another case report by Tripathi and colleagues, of a 55-year-old woman [82]. Self-injection of ND in external genitalia was reported as the cause of a paraffinoma and an above skin ulceration by Balighia and colleagues, in a 56-year-old man [83]. ND is generally used in the injectable form to improve performance [23], regularly or occasionally, with a combination of multiple AASs.
NADPH Oxidase activity and mRNA levels
To evaluate the safety and efficacy of the anabolic steroid, nandrolone decanoate (Deca Durabolin) in patients with HIV wasting who are resistant to nutritional intervention. In summary, treatment with nandrolone resulted in increased LBM and
improved functional status in dialysis patients. Nandrolone was safe
and well tolerated during 6 months of treatment, but further studies
are needed to assess the long-term safety and benefits of such
treatment. With overdosage, you may encounter a range of side effects including water retention, an increased risk of bleeding, changes in skin color, or mood alterations such as irritability and depression. Notably, men could experience side effects such as testicular atrophy, erectile dysfunction, or a reduced sperm count. On the other hand, if women surpass the suggested dosages, they might face virilization symptoms including voice deepening, unusual hair growth, or menstrual cycle changes.
The result attained clearly shows that NAC was able to fully prevent the enhanced expression of CD133 in nandrolone-treated cells (Fig. 7D). CD133 is a surface cell marker identifying a subset of cancer cells, including hepatocellular carcinomas, with stemness properties. Figure 6A shows that treatment of HepG2 cell line with nandrolone caused an almost five fold increase of CD133 positive HepG2 cells, assessed by flow-cytometry. Notably, the MFI in ND-treated cells also increased but not of the extent of the percentage of the CD133+ cells. This would suggest that ND is mainly effective in inducing the expression of the stemness marker in CD133− cellular subset rather than enhancing its expression in CD133 cells. However, the possibility that nandrolone enhances the stemness marker in very-low-CD133 expressing HepG2 cells cannot be ruled out.

L. Alves received a scholarship from Fundação Cearense de Apoio ao Desenvolvimento Científico e Tecnológico (FUNCAP). Adverse events (AEs) and serious adverse events (SAEs) were recorded according to standard methods. Local tolerability at the administration site was assessed directly and at 2 and 24 h after dosing as an additional safety measure.
Nandrolone – Clinical Pharmacology
Heart and Skeletal muscles samples fixed by 10% neutral formalin then washed to be dehydrated with ascending grades of alcohol. Following tissue homogenization, at 4000 rpm centrifugation was done for 15 min at 4 °C with the supernatant removed for analysis. The samples were preserved by freezing at -80 °C that made them stable for at least one month.
Accordingly to this notion it is conceivable that a pro-oxidative condition might elicit different and even opposite responses depending on the antioxidant cellular phenotype. Thus, the apparent beneficial antitumoral effect on differentiated cancer cells is counterbalanced by the harmful enrichment of the cancer stem cells compartment, which appears to be the major determinant of tumorigenesis60,61. Thiol residues are mainly found in proteins and in low-molecular-mass metabolites such as the highly abundant glutathione (GSH), and can be reversibly oxidized by ROS to nitrosothiols or sulfenic acids, decreasing its cellular levels. On the other hand, carbonyl groups can be formed by the oxidation of proteins by ROS.
Indeed, treatment of HepG2 with ND under our experimental conditions did not result in any change neither of the IGFR1 expression or IGF-1 release or Akt-signaling activation (data not shown). ROS are normally produced by virtually all cells of living organisms, and are able to act in the redox-dependent regulation of different cellular functions, including response to stressors, angiogenesis, cell proliferation and other [22]. In order to maintain intracellular ROS at adequate levels, antioxidant systems react with these molecules producing less reactive compounds. Conceptually, an imbalance between pro-oxidant compounds and antioxidant defenses leads to oxidative stress, but this concept has recently been redefined as the “disruption of redox signaling and control” [11].
