ANDROID 10 vs METANDREN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Androgen receptor agonist; testicular androgen responsible for development and maintenance of male sex characteristics and anabolic effects; increases protein synthesis and muscle mass.
Androgen receptor agonist; binds to androgen receptors in target tissues, activating gene transcription and promoting protein synthesis, growth of male reproductive organs, and secondary sexual characteristics.
Testosterone undecanoate 750 mg (3 mL) intramuscular injection every 10 weeks, or testosterone cypionate 50-400 mg intramuscular injection every 2-4 weeks. For gel formulations: 50-100 mg transdermally once daily.
Oral: 5-25 mg once daily for testosterone replacement therapy in adult males.

8 hours; clinical context: steady-state achieved in 2-3 days, dosing interval 8-12 hours.
The terminal elimination half-life of methyltestosterone is approximately 3-4 hours. This short half-life necessitates multiple daily dosing (e.g., 10-50 mg orally 1-3 times daily) to maintain therapeutic androgen levels. However, due to its oral administration and first-pass metabolism, the clinical effect may last longer.
Renal: 90% as glucuronide and sulfate conjugates, 6% as unchanged drug; fecal: 4%.
Metandren (methyltestosterone) is primarily metabolized in the liver and excreted in the urine as glucuronide and sulfate conjugates. Approximately 90% of a dose is excreted renally, with less than 5% eliminated via feces. Biliary excretion is minimal.
