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 and activates androgen receptors (AR) in target tissues, promoting the development and maintenance of male secondary sexual characteristics and anabolic effects. It also suppresses gonadotropin-releasing hormone (GnRH) secretion via negative feedback, reducing endogenous testosterone production.
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 once daily or divided twice daily, or 10-25 mg buccally twice daily.

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.
2-4 hours (terminal); requires multiple daily dosing or transdermal route due to short half-life.
Approximately 90% of testosterone metabolites are excreted in urine as glucuronide and sulfate conjugates; 6% are excreted in feces via bile.
Renal (primarily as glucuronide and sulfate conjugates, ~90%); fecal (~10%). Unchanged drug is minimal.
