TESTIM vs TESTOSTERONE PROPIONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone replacement therapy; binds to and activates androgen receptors, modulating gene expression leading to male sexual development and maintenance of secondary sexual characteristics.
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 5 g (1 tube) of 1% gel to clean, dry, intact skin of the shoulders, upper arms, or abdomen once daily, preferably in the morning. Dosage may be adjusted to 10 g (2 tubes) depending on clinical response. Apply immediately after opening and avoid bathing or swimming for at least 30 minutes.
50-400 mg intramuscularly every 2-4 weeks. For androgen replacement, 50-100 mg IM every 2 weeks.

moderateTestosterone propionate + Tranylcypromine
"The risk or severity of adverse effects can be increased when Testosterone propionate is combined with Tranylcypromine."

moderateTestosterone propionate + Pirlindole
"The risk or severity of adverse effects can be increased when Testosterone propionate is combined with Pirlindole."
Clinical Note
moderateTerminal elimination half-life of testosterone from serum is approximately 10-100 minutes after intravenous administration, but after transdermal application of Testim, the apparent half-life is longer (around 1-2 hours) due to continued absorption from the skin depot. The half-life of active metabolites (e.g., dihydrotestosterone) is about 2-3 hours.
Terminal half-life: 0.8–1.2 hours (rapid elimination due to short ester chain; requires frequent dosing).
Testosterone is primarily excreted in 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%.
