Managing testosterone levels through therapy requires precision. Whether you’re under medical supervision for testosterone replacement therapy (TRT), bodybuilding, or hormone balancing, accurate dosing is critical for effectiveness and safety. The Testosterone Dose Calculator is a powerful tool designed to help you determine how much testosterone you’re receiving per dose based on your medication’s concentration, injection volume, and frequency.
Testosterone Dose Calculator
What Is a Testosterone Dose Calculator?
A Testosterone Dose Calculator is a medical utility tool used to compute the total testosterone dosage based on:
- Concentration of testosterone (e.g., 200 mg/mL)
- Injection volume (e.g., 0.5 mL or 1 mL)
- Frequency (e.g., weekly, bi-weekly)
It helps users accurately track their total testosterone intake, adjust dosages safely, and work more effectively with their healthcare providers.
Why Use a Testosterone Dose Calculator?
Accurate testosterone dosing is essential because:
- Overdosing may lead to high estrogen conversion, aggression, or cardiovascular risk.
- Underdosing can result in fatigue, low libido, depression, or muscle loss.
- Consistency is key in hormone replacement therapy to avoid mood swings and side effects.
This calculator provides:
- Exact testosterone intake per dose
- Weekly or monthly dosage averages
- Easy adjustments for different strengths and volumes
Who Should Use This Calculator?
- TRT patients working with prescribed testosterone injections
- Athletes/bodybuilders adjusting cycles (under medical supervision)
- Clinicians who need to calculate and verify dosing for patients
- Health-conscious individuals tracking bioidentical hormone therapy (BHT)
How to Use the Testosterone Dose Calculator
Step-by-Step Instructions
- Enter the Concentration (mg/mL)
Common concentrations: 100 mg/mL, 200 mg/mL, 250 mg/mL - Enter the Injection Volume (mL)
Example: 0.5 mL, 1 mL, 1.5 mL, etc. - Select the Frequency
- Weekly
- Bi-weekly (every 2 weeks)
- Every 3 days
- Monthly
- Click “Calculate”
The calculator will output:
- Dosage per injection (mg)
- Total weekly dose
- Monthly average dose (optional)
Testosterone Dose Calculation Formula
Here’s the simple formula behind the scenes:
Dose (mg) = Concentration (mg/mL) × Volume (mL)
For multiple injections:
Weekly Total = (Dose per injection × Frequency per week)
Example Calculations
💉 Example 1: Standard TRT Dosage
- Concentration: 200 mg/mL
- Volume: 0.5 mL
- Frequency: 1x per week
Dose = 200 × 0.5 = 100 mg/week
💉 Example 2: Divided Injections for Smoother Levels
- Concentration: 200 mg/mL
- Volume: 0.25 mL
- Frequency: Twice per week
Dose = 200 × 0.25 = 50 mg per injection
Weekly Total = 50 × 2 = 100 mg/week
💉 Example 3: Bodybuilding Cycle (not medically recommended)
- Concentration: 250 mg/mL
- Volume: 1 mL
- Frequency: Every 3 days
Injections/week ≈ 2.33
Dose = 250 mg/injection × 2.33 ≈ 582.5 mg/week

Tips for Safe Testosterone Dosing
- Always consult your doctor before adjusting doses.
- Split larger doses into smaller injections to maintain steady levels.
- Use the same syringe size and type for consistency.
- Monitor estradiol (E2), SHBG, and free T alongside total testosterone.
- Track your mood, energy, and libido to correlate with your numbers.
20 Frequently Asked Questions (FAQs)
1. What is the purpose of this calculator?
To calculate how much testosterone you’re receiving per injection and per week based on concentration and volume.
2. What is a common TRT dose?
Most therapeutic doses range from 100–200 mg/week, depending on the individual.
3. Can I use this calculator for testosterone enanthate or cypionate?
Yes, the formula applies to all injectable forms with known concentrations.
4. Is this calculator accurate for subcutaneous injections?
Yes. It calculates dose based on volume, regardless of injection route.
5. What if I inject every 3.5 days?
You can use the calculator with “twice weekly” and input your dose accordingly.
6. Can I input 0.2 mL as volume?
Yes, the calculator supports any decimal values (e.g., 0.1 mL, 0.3 mL).
7. Will this work for other hormones like HCG or HGH?
Yes, if you know the concentration (IU/mL or mg/mL), the formula is universal.
8. Is it suitable for bodybuilders?
Yes, but non-medical use should be approached with caution and under supervision.
9. How do I convert mg to mL?
You don’t need to—just use the calculator. But formula: mL = mg / concentration (mg/mL)
10. Can I calculate monthly dose totals?
Yes. Multiply your weekly dose by 4.33 (average weeks in a month).
11. Can I input custom frequencies?
Most calculators allow every 3 days, weekly, bi-weekly, and monthly. Custom math is possible manually.
12. Does it account for bioavailability?
No, it calculates the raw dose. Bioavailability is determined by body metabolism.
13. Is this calculator for oral testosterone?
No, oral testosterone has different pharmacokinetics and is rarely prescribed.
14. Will this help me track side effects?
Indirectly. By knowing dose, you can correlate symptoms with levels.
15. What’s the risk of taking too much testosterone?
Risks include high estrogen, water retention, acne, hair loss, liver strain, and cardiovascular issues.
16. Can this calculator be used by clinics?
Yes, many clinics use similar tools for patient protocols.
17. How do I know my concentration?
Check your prescription label. Common strengths are 100, 200, or 250 mg/mL.
18. Does the injection site matter?
Not for dose calculation, but absorption rates may vary slightly.
19. What if I skip an injection?
Your weekly average will decrease. You can re-calculate to adjust.
20. Is this calculator free to use?
Yes, it’s a free, accessible tool for anyone managing testosterone therapy.
