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.
Methyltestosterone is a synthetic androgen that binds to androgen receptors, activating transcription of androgen-responsive genes, leading to increased protein synthesis, muscle growth, and secondary sexual characteristic development.
Apply one 30 mg metered-dose transdermal system to abdomen or upper arm once daily at the same time each day.
10-50 mg orally or buccally 1-3 times daily; or 25-100 mg IM every 2-4 weeks.

Terminal elimination half-life is 3–4 hours; not clinically significant for once-daily transdermal administration due to sustained absorption.
Terminal half-life approximately 2.7–3.8 hours; brief due to rapid hepatic metabolism.
Primarily renal (90% as glucuronide and sulfate conjugates, 10% unchanged); approximately 1% fecal.
Primarily renal as conjugated metabolites; ~90% urinary, ~6% fecal within 4 days.
