Testosterone Gel 1.62% Dosing Calculation for 30-Day Supply
For a 30-day prescription of testosterone gel 1.62% using 1 pump to each thigh daily (2 pumps total per day), you need to dispense 75 grams of gel.
Calculation Breakdown
Each pump actuation of testosterone gel 1.62% delivers 20.25 mg of testosterone in 1.25 grams of gel 1
The prescribed regimen is 1 pump per thigh daily = 2 pumps per day total 1
Daily gel amount: 2 pumps × 1.25 g per pump = 2.5 grams per day 1
30-day supply: 2.5 g/day × 30 days = 75 grams total 1
Clinical Context
This dosing regimen (2 pumps daily = 40.5 mg testosterone) falls within the typical dosing range of 50-100 mg/day for testosterone gel formulations 2
Application to the thighs is an acceptable site, though upper arms/shoulders demonstrate approximately 30-40% higher bioavailability compared to abdominal or lower extremity application 3
If testosterone levels are inadequate with thigh application, consider switching to upper arms/shoulders rather than increasing dose, as this site achieves superior absorption 4, 3
Monitoring Considerations
Check testosterone levels 2-3 months after initiation, understanding that peak values occur 6-8 hours after gel application 2
Testosterone gel provides more stable day-to-day levels without the peaks and valleys seen with injections, making it the preferred initial formulation 2
Once stable levels are confirmed, monitoring every 6-12 months is sufficient, along with regular hematocrit/hemoglobin and PSA monitoring 2
