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.
Androgen receptor agonist; binds to androgen receptors, stimulating protein synthesis, growth of male reproductive tissues, and development of secondary sexual characteristics.
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.
Testosterone enanthate 50-400 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.
8 hours for testosterone; clinical context: requires daily or weekly dosing for replacement therapy
Approximately 90% of testosterone metabolites are excreted in urine as glucuronide and sulfate conjugates; 6% are excreted in feces via bile.
Renal (90% as metabolites, 5% unchanged), biliary/fecal (10%)
