Testosterone Cream Dosing Calculation
For a 2 mg/mL testosterone cream dispensed via Topi-Click at 0.25 mL per click, each click delivers 0.5 mg of testosterone.
Daily Prescription Based on Target Dose
The number of clicks you need depends on your prescribed daily testosterone dose:
- 10 mg daily = 20 clicks
- 20 mg daily = 40 clicks
- 25 mg daily = 50 clicks
- 40 mg daily = 80 clicks
- 50 mg daily = 100 clicks
Standard Starting Dose
Most testosterone replacement protocols start at 40-50 mg daily for men, which would translate to 80-100 clicks daily with your formulation 1. However, this is an unusually high number of clicks and suggests your concentration may be too dilute for practical use.
Critical Dosing Issue
Your 2 mg/mL concentration is significantly more dilute than standard commercial testosterone preparations. FDA-approved testosterone gel 1.62% delivers 20.25-81 mg of testosterone in volumes of 1.25-5 g 1. Your formulation would require 10-40 mL (40-160 clicks) to achieve equivalent dosing, which is impractical for daily application.
Practical Recommendations
You should discuss reformulation with your prescriber to a higher concentration (typically 50-100 mg/mL for compounded testosterone creams) to reduce the number of daily clicks to a manageable 1-2 clicks 2.
Dosing Algorithm
- Determine your target testosterone dose (typically 40-50 mg daily for initial therapy in men)
- Calculate clicks needed: Target dose (mg) ÷ 0.5 mg per click
- If clicks exceed 10-15 daily, request concentration adjustment
Monitoring Requirements
- Measure morning serum testosterone at 14 and 28 days after starting
- Target range: 350-750 ng/dL 1
- Adjust dose by 20.25 mg increments based on levels
- Recheck periodically thereafter
Note: The Topi-Click dispenser demonstrates superior accuracy and precision compared to airless pumps and does not require calibration adjustments for different cream bases 2, making it reliable for consistent dosing once the appropriate concentration is established.
