Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone is an androgen receptor agonist; it binds to androgen receptors, leading to changes in gene expression that promote male secondary sexual characteristics and maintain libido, muscle mass, and bone density.
Synthetic androgen receptor agonist; binds to androgen receptors, modulating gene expression and promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
Apply one 2.5 mg or 5 mg transdermal system to clean, dry, intact skin on the abdomen, upper arms, or thighs once daily, preferably in the morning. Starting dose is 5 mg daily; adjust based on serum testosterone levels.
Adults: 5-20 mg orally once daily. For replacement therapy, 5-10 mg daily; for hypogonadism, 5-20 mg daily for several months.

Terminal elimination half-life is approximately 10–100 minutes (rapid), but due to transdermal absorption, effective half-life is extended to about 8–10 hours after patch application.
Terminal elimination half-life: 9.2 hours; clinical context: supports once-daily dosing for androgen replacement, with steady-state achieved in ~2 days
Approximately 90% of testosterone metabolites are excreted in urine as glucuronide and sulfate conjugates; 6% are excreted in feces via bile.
Renal: 90% as glucuronide and sulfate conjugates; fecal: 10%
