Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic androgen receptor agonist; binds to androgen receptors, modulating gene expression and promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
Testosterone is an androgen receptor agonist. It binds to and activates androgen receptors, leading to changes in gene expression that promote the development and maintenance of male secondary sexual characteristics, anabolic effects, and spermatogenesis.
Adults: 5-20 mg orally once daily. For replacement therapy, 5-10 mg daily; for hypogonadism, 5-20 mg daily for several months.
Apply 4 mg (one 4 mg/24 hr system) or 6 mg (one 6 mg/24 hr system) transdermally once daily, applied to clean, dry, intact skin on the back, abdomen, thighs, or upper arms. Rotate application sites with an interval of at least 7 days.

Terminal elimination half-life: 9.2 hours; clinical context: supports once-daily dosing for androgen replacement, with steady-state achieved in ~2 days
The terminal elimination half-life of testosterone administered transdermally is approximately 1.5–2 hours. This short half-life requires daily application of the patch to maintain therapeutic levels.
Renal: 90% as glucuronide and sulfate conjugates; fecal: 10%
Testosterone is excreted primarily in the urine as glucuronide and sulfate conjugates (approximately 90%), with about 6% excreted in feces via bile. Less than 1% is excreted unchanged.
