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.
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 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.
10-50 mg orally or buccally 1-3 times daily; or 25-100 mg IM every 2-4 weeks.

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 half-life approximately 2.7–3.8 hours; brief due to rapid hepatic metabolism.
Approximately 90% of testosterone metabolites are excreted in urine as glucuronide and sulfate conjugates; 6% are excreted in feces via bile.
Primarily renal as conjugated metabolites; ~90% urinary, ~6% fecal within 4 days.
