TRT & Testosterone Dosage Calculator – A Step-by-Step Guide

Are you looking to optimize your testosterone therapy or cycle? Our TRT & Testosterone Dosage Calculator helps you estimate the right dose based on your goals. Follow this simple guide to get accurate results.

Step 1: Enter Your Current Testosterone Level

• Get your latest blood test results (measured in ng/dL or nmol/L).
• If you don’t know your level, a typical baseline is:
  • Healthy young men: 400–700 ng/dL
  • Low T (hypogonadism): Below 300 ng/dL

🔹 Example: If your bloodwork shows 350 ng/dL, enter that value.

Step 2: Set Your Desired Testosterone Level

• For TRT (Therapeutic Use): Aim for 700–1200 ng/dL (natural high-normal range).
• For Performance Enhancement (Cycles): Some users target 1500–3000+ ng/dL (not recommended without medical supervision).

🔹 Example: If you want 900 ng/dL for TRT, input that number.

Step 3: Select Your Testosterone Ester

Different esters release testosterone at varying speeds:

• Enanthate/Cypionate: Slow release (~5–7 days), best for TRT.
• Propionate: Fast release (~2–3 days), requires frequent injections.
• Suspension (No Ester): Immediate release (daily injections).

🔹 Example: If using Testosterone Cypionate, select it from the dropdown.

Step 4: Choose Injection Frequency

More frequent injections = more stable levels.

• Once per week: Simple but may cause peaks & crashes.
• Twice per week (E3.5D): Best balance for most users.
• Every Other Day (EOD): Smoothest levels, good for Propionate.

🔹 Example: If injecting twice weekly, select that option.

Step 5: Calculate & Understand Your Results

After submitting, the calculator provides:
✅ Weekly Testosterone Dose (mg/week) – Total amount needed.
✅ Per-Injection Dose (mg) – How much to inject each time.
✅ Estimated Peak & Trough Levels – How your levels fluctuate.

🔹 Example Output:

• Weekly Dose: 120 mg
• Per Injection (2x/week): 60 mg
• Estimated Peak: ~1100 ng/dL
• Estimated Trough: ~700 ng/dL

Important Notes & Disclaimer

• Bloodwork is Essential: Always confirm doses with lab tests (4–6 weeks after starting).
• Individual Responses Vary: Body fat, SHBG, and metabolism affect results.
• Consult a Doctor for TRT: Self-administration carries risks.
• Steroid Cycles Require PCT: High doses suppress natural testosterone.
