Methyltestosterone Research Guide

Full name: Methyltestosterone (Oral Testosterone)

One of the first orally active androgens, a 17aa form of testosterone used historically for hypogonadism and delayed puberty. Largely superseded by safer TRT options due to liver toxicity. Educational reference only.

How Methyltestosterone Works

A 17-alpha-alkylated testosterone that survives first-pass liver metabolism, allowing oral dosing. It acts on androgen receptors like testosterone and aromatizes to estrogen, but its 17aa structure makes it hepatotoxic.

Dosing Protocol

• Typical dose: Medical: ~10-50 mg/day (historical)
• Frequency: Daily
• Duration: Short courses
• Route: Oral or buccal tablet

Reported Benefits

• Oral testosterone activity
• Treats androgen deficiency (historical)
• Convenience of oral dosing

Potential Side Effects

• Liver toxicity
• Estrogenic effects
• Adverse lipids
• Testosterone suppression
• Largely obsolete
