Stanozolol 2mg tablets

The abuse of anabolic-androgenic steroids (AAS) is associated with numerous adverse cardiovascular effects, including ventricular hypertrophy, myocardial fibrosis, and sudden cardiac death (SCD), which is a term that identifies a sudden death occurred due to cardiac conditions, congenital or acquired, particularly among young athletes and bodybuilders. This systematic review examines cases of AAS-related deaths, with a particular focus on autoptic, histopathological, immunohistochemical, and toxicological findings that highlight cardiac remodeling and myocardial damage. Numerous fatal cases were analyzed, primarily involving young men with a history of AAS abuse. Autopsy examinations revealed significant cardiac abnormalities such as left ventricular hypertrophy, coronary thrombosis, and dilated cardiomyopathy. Histopathological analyses showed focal myocardial necrosis, myocardial fiber disarray, and interstitial fibrosis, while immunohistochemical studies confirmed the presence of markers such as troponin T, fibronectin, and the C5b-9 complement complex, indicating inflammation, fibrosis, and necrosis. Toxicological analyses frequently detected testosterone, stanozolol, trenbolone, and nandrolone in blood, urine, and hair samples, confirming prolonged use of these substances. The results suggest that AAS-induced hypertrophy and fibrosis contribute to the pathogenesis of fatal arrhythmias and sudden cardiac death, even in the absence of pre-existing coronary artery disease. This review highlights the importance of integrating histopathological, immunohistochemical, and toxicological analyses with autopsy findings in forensic investigations to accurately identify AAS-related deaths and develop prevention strategies to reduce the abuse of these substances, particularly among young athletes and bodybuilders.

Adolescents commonly co-abuse many drugs including anabolic androgenic steroids either they are athletes or non-athletes. Stanozolol is the major anabolic used in recent years and was reported grouped with cannabis. The current study aimed at evaluating the biochemical and histopathological changes related to the hypertrophic effects of stanozolol and/or cannabis whether in condition of exercise practice or sedentary conditions. Adult male Wistar albino rats received either stanozolol (5 mg/kg, s.c), cannabis (10 mg/kg, i.p.), and a combination of both once daily for two months. Swimming exercise protocol was applied as a training model. Relative heart weight, oxidative stress biomarkers, cardiac tissue fibrotic markers were evaluated. Left ventricular morphometric analysis and collagen quantification was done. The combined treatment exhibited serious detrimental effects on the heart tissues. It increased heart tissue fibrotic markers (Masson's trichrome stain (p < 0.001), cardiac COL3 (p < 0.0001), and VEGF-A (p < 0.05)), lowered heart glutathione levels (p < 0.05) and dramatically elevated oxidative stress (increased malondialdehyde (p < 0.0001) and 8-OHDG (p < 0.0001)). Training was not ameliorating for the observed effects. Misuse of cannabis and stanozolol resulted in more hypertrophic consequences of the heart than either drug alone, which were at least largely assigned to oxidative stress, heart tissue fibrotic indicators, histological alterations, and morphometric changes.

Abstract Anabolic‐androgenic steroids (AASs) are a subclassification of image performance enhancing drugs (IPEDs). While AAS use is most prevalent among people in athletics, there is also high lifetime prevalence of AAS use among prisoners. This study reports the qualitative detection of AASs in seized samples from the Scottish prisons from 2019–2023. Additionally, methods were developed for the quantitative analysis of AASs using gas chromatography–mass spectrometry (GC–MS) and applied to 61 samples of tablets or powders seized from Scottish prisons between July 2022 and July 2023. Since 2022, there has been an increase in AAS detections in the Scottish prisons. Oxymetholone was the most prevalent AAS, followed by metandienone (methandrostenolone, methandienone), methyltestosterone, oxandrolone, mestanolone (methylandrostanolone), stanozolol, and androstenedione. Multiple AASs were found in 21 samples and 10 samples contained other drugs, including amitriptyline, sertraline, zopiclone, mirtazapine, sildenafil, etizolam, Δ 9 ‐tetrahydrocannabinol, and the synthetic cannabinoid MDMB‐INACA. Most AAS samples were tablets (77.0%), although they were also detected in powders, herbal material, e‐cigarettes, and a fragmented soap bar‐type sample. There was a large variation in the concentration of AASs in the tablets and powders seized from the Scottish prisons, demonstrating AASs are another highly variable component of the polydrug use situation in prisons, the effects of which need to be examined further.

Polydrug use among teenagers is widespread and emergent either among athletes or non-athletes. It is reported that stanzolol (Stanz) is commonly abused with cannabis (Cann), this combination probably affects the testicular functions negatively. Aim The present study aimed to evaluate the toxic effects of Stanz and or Cann on reproductive hormones and testicular enzymes. Male Wistar rats were administered Stanz (5 mg/kg, s.c., once per week) and Cann (20 mg/kg, i.p., daily) either alone or in combination for two months, in exercise or sedentary conditions. Swimming exercise protocol was applied. Administration of both Stanz and Cann induced testicular damage, as evidenced by altered hormones, oxidative stress, and testicular enzymes. The testis tissue was significantly injured by the combined administration. In serum, levels of free testosterone, follicular stimulating hormone (FSH), lutenizing hormone (LH) were markedly reduced, while sorbitol dehydrogenase level increased. Moreover, tissue malondialdehyde (MDA) was significantly increased, glutathione (GSH) content decreased, testicular N-acetyl-β-glucosaminidase (NAG) and Myeloperoxidase (MPO) were increased. SIRT1 and STS mRNA expression were downregulated. Besides, distinct histopathological changes were detected in testis of Stanz and Cann injected rats. Nevertheless, Stanz, Cann or combined treatment showed a considerable up-regulation of immunoexpression of inducible nitric oxide synthase (iNOS) and caspase-3 in testes tissue. Oxidative stress and inflammation played a significant role in the observed pathological changes. Training was partially ameliorating for the observed effects. Use of the drugs in sedentary rats had more detrimental effects on testes. Although exercise could palliate the damage partially, it was not fully protective.

BACKGROUND: There are many forms of anabolic steroids, including stanozolol (Winstrol), which are popular for their muscle-building effects but dangerous to the heart. This present work is aimed at evaluating the pharmacologica impact of allicin, a natural attribute obtained from garlic, on obstructing cardiac injury in rabbits that received stanozolol. METHODS: Thirty rabbits were divided into three groups: control, stanozolol-treated, and stanozolol plus allicin. Cardiac function was assessed by measuring troponin, creatine kinase (CK), Galectin-3, and GDF-15. Oxidative stress and antioxidant markers, including malondialdehyde (MDA), glutathione, and catalase, were analyzed. Inflammatory mediators such as C-reactive protein (CRP), interleukin-6 (IL-6), NF-κB, iNOS, nitric oxide (NO), tumor necrosis factor-alpha (TNF-α), and interleukin-1 beta (IL-1β) were evaluated. Lipid profile parameters, including total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL), were measured. Histopathological examination assessed myocardial damage, fibrosis, and collagen deposition. RESULTS: Stanozolol administration significantly increased cardiac damage markers, oxidative stress, and inflammatory mediators while causing dyslipidemia, characterized by elevated LDL and total cholesterol and reduced HDL. Allicin co-administration effectively countered these effects by reducing oxidative stress and inflammation, restoring antioxidant balance, and improving lipid profiles. Histopathological analysis revealed severe myocardial disorganization, necrosis, and fibrosis in the stanozolol group, whereas the allicin-treated group exhibited preserved myocardial structure with reduced collagen deposition. CONCLUSION: Allicin significantly mitigates stanozolol-induced cardiotoxicity by reducing oxidative stress, inflammation, lipid dysregulation, and myocardial damage, as evidenced by biochemical and histopathological findings. These results suggest that allicin may serve as a potential therapeutic agent to counteract the cardiovascular risks associated with anabolic steroid use.

Background: In order to address complex scenarios in anti-doping science, especially in cases where an unintentional exposure of athletes to prohibited substances and a corresponding contamination of doping control samples at the collection event are argued, an understanding of tissue-specific drug metabolism is essential. Hence, in this study, the metabolic capacity of the seminal vesicle using in vitro assays was investigated. Methods: The aim was to assess whether selected doping-relevant substances—stanozolol, LGD-4033, GW1516, trimetazidine, and anastrozole—are metabolised in seminal vesicle cellular fractions (SV-S9) and how that metabolism compares to biotransformations induced by human liver S9 fractions (HL-S9). Liquid chromatography coupled to high-resolution/accurate mass spectrometry (LC HRAM MS) enabled the sensitive detection and identification of metabolites, revealing a limited metabolic activity of SV-S9. Results: For LGD-4033, GW1516, and trimetazidine, minor metabolic transformations were observed, whereas no metabolites of stanozolol or anastrozole were detected. Gene expression analysis using digital polymerase chain reaction (dPCR) confirmed transcripts of CYP2D6, CYP2E1, and CYP2C9 in SV-S9, though no enzymatic activity was detected. Gene expression and enzymatic activity in CYP3A4 and CYP1A2—major hepatic enzymes—were absent in SV-S9. Conclusions: Overall, these pilot study results suggest that the seminal vesicle has only a low capacity for xenobiotic metabolism, which translates into a limited role in the biotransformation of drugs and, hence, the metabolic pattern.
