TESTODERM TTS vs TESTOSTERONE PROPIONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone is an androgen receptor agonist. It binds to and activates androgen receptors, leading to changes in gene expression that promote the development and maintenance of male secondary sexual characteristics, anabolic effects, and spermatogenesis.
Testosterone propionate is a short-acting androgen receptor agonist. It binds to androgen receptors, leading to activation of androgen-responsive genes and promotion of male secondary sexual characteristics, anabolic effects, and erythropoiesis.
Apply 4 mg (one 4 mg/24 hr system) or 6 mg (one 6 mg/24 hr system) transdermally once daily, applied to clean, dry, intact skin on the back, abdomen, thighs, or upper arms. Rotate application sites with an interval of at least 7 days.
50-400 mg intramuscularly every 2-4 weeks. For androgen replacement, 50-100 mg IM every 2 weeks.

Clinical Note
moderateTestosterone propionate + Tranylcypromine
"The risk or severity of adverse effects can be increased when Testosterone propionate is combined with Tranylcypromine."
Clinical Note
moderateTestosterone propionate + Procarbazine
"The risk or severity of adverse effects can be increased when Testosterone propionate is combined with Procarbazine."
Clinical Note
moderateTestosterone propionate + Pirlindole
"The risk or severity of adverse effects can be increased when Testosterone propionate is combined with Pirlindole."
Clinical Note
moderateThe terminal elimination half-life of testosterone administered transdermally is approximately 1.5–2 hours. This short half-life requires daily application of the patch to maintain therapeutic levels.
Terminal half-life: 0.8–1.2 hours (rapid elimination due to short ester chain; requires frequent dosing).
Testosterone is excreted primarily in the urine as glucuronide and sulfate conjugates (approximately 90%), with about 6% excreted in feces via bile. Less than 1% is excreted unchanged.
Renal: 90% (as glucuronide and sulfate conjugates); Fecal/Biliary: 10%.
