- Content: 100 tablets | 10 mg per tablet
- Manufactured in: Europe
Product Overview
Stanozolol 10 mg is a fast-acting, 17--alkylated DHT-derived oral anabolic agent originally known as Winstrol. It is widely used in research focused on lean muscle development, nitrogen retention, and muscle hardening, as well as airway-fat loss and bronchodilation protocols.
Its high oral bioavailability (~100%) and short 4–6 hour half-life support multiple daily sampling in pharmacokinetic and pharmacodynamic studies. Peak plasma concentrations are reached within 1–2 hours. Due to long-detectable urinary metabolites, any exposure is virtually guaranteed to result in a positive anti-doping test.
Key Research Highlights
Anabolic effects: Rapid lean-mass gain, nitrogen retention, and enhanced FEV within 30 minutesAR-binding ratio: ~2–4 higher myotrophic potency vs testosterone, with reduced androgenicityEndurance support: Increases hemoglobin and hematocrit in animal and human studiesCholestatic risk: Liver stress and rare failure cases reported at 30–50 mg/day chronic useLipid warning: Decreases HDL and increases LDL; caution advised in long-term trialsCardiovascular strain: -agonist action may cause tremor, tachycardia, and electrolyte shiftsWADA compliance: Listed on S1 banned substances with 8+ day urine detection via LC-MS/MS
Suggested Laboratory Applications
Lean mass and cutting-phase muscle modeling
Pulmonary recovery and airway-opening protocols
Nitrogen balance and protein metabolism studies
Erythropoiesis and red blood cell enhancement trials
