ANDROID 5 vs METANDREN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.
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.
2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
Oral: 5-25 mg once daily for testosterone replacement therapy in adult males.

Terminal elimination half-life is 3.5–5.5 hours; clinical effects may persist for several days due to active metabolites.
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.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
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.
