8 Or 4 Weeks Anavar? Anabolic Steroids: A Comprehensive Overview --- 1. What Are Anabolic Steroids? Anabolic steroids are synthetic versions of the male hormone testosterone. They were originally created for medical uses—treating hormone deficiencies, wasting diseases, and certain types of anemia. Today they’re most commonly known as performance‑enhancing drugs used by athletes, bodybuilders, and sometimes by people seeking a more muscular appearance. Steroid Common Name(s) Typical Use Methandrostenolone Dianabol Muscle mass & strength Oxandrolone Anavar Lean muscle gain, post‑surgery recovery Stanozolol Winstrol Strength & power Nandrolone Deca‑Durabolin Anabolic support, joint health --- 2. How do anabolic steroids work? Anabolic steroids are synthetic derivatives of the male sex hormone testosterone. They mimic testosterone’s effects on muscle cells, but they are chemically altered to: Increase "anabolism" – the building up of new tissue (protein synthesis) Reduce "catabolism" – breakdown of muscle proteins Suppress natural hormone production – leading to potential side‑effects Key mechanisms: Mechanism What Happens Binding to Androgen Receptors Steroids enter muscle cells and bind androgen receptors. This triggers a cascade that promotes the transcription of genes involved in protein synthesis. Inhibition of Proteolysis They reduce the activity of proteasomes (protein‑degrading complexes) by down‑regulating E3 ubiquitin ligases such as MuRF1 and Atrogin‑1, which are upregulated during catabolism. Stimulation of Satellite Cells Steroids increase satellite cell proliferation and differentiation, leading to muscle hypertrophy. Reduction in Inflammatory Cytokines By lowering levels of TNF‑α and IL‑6, they mitigate inflammation that otherwise promotes catabolic pathways. 2. How steroids help to counteract the catabolism caused by COVID‑19 Mechanism Effect on muscle tissue Relevance to COVID‑19 Inhibition of NF‑κB & TNF‑α signaling Decreases expression of ubiquitin ligases (MuRF1, MAFbx) and proteasomal activity. Reduces virus‑induced cytokine storm that would otherwise accelerate muscle breakdown. Upregulation of protein synthesis pathways (e.g., Akt/mTOR) Promotes ribosomal biogenesis and translation initiation. Compensates for the suppression of anabolic signaling caused by systemic inflammation. Reduction of oxidative stress Limits mitochondrial damage, preserves ATP production. Prevents further activation of proteolytic cascades triggered by reactive oxygen species during critical illness. Maintenance of nitrogen balance Decreases net protein catabolism
