Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone replacement therapy; testosterone binds to and activates androgen receptors, influencing gene transcription and protein synthesis, leading to the development of male secondary sex characteristics and maintenance of libido, muscle mass, and bone density.
Testosterone is an androgen receptor agonist; it binds to and activates androgen receptors, leading to changes in gene expression that promote male sexual development, maintenance of secondary sexual characteristics, and anabolic effects.
Apply one 30 mg metered-dose transdermal system to abdomen or upper arm once daily at the same time each day.
Subcutaneous implantation: 150-450 mg every 3-6 months. Individualize based on serum testosterone levels and clinical response.

Terminal elimination half-life is 3–4 hours; not clinically significant for once-daily transdermal administration due to sustained absorption.
Terminal half-life: 8-10 days; due to prolonged release from subcutaneous depot, effective half-life extends to 2-3 weeks.
Primarily renal (90% as glucuronide and sulfate conjugates, 10% unchanged); approximately 1% fecal.
Renal: ~90% as glucuronide and sulfate conjugates, ~10% unchanged; fecal: ~6% via biliary elimination.
