Testosterone Replacement Therapy (TRT) is a powerful tool for both men and women experiencing the symptoms of hormone imbalance. While the treatment method varies from patient to patient, injectable testosterone remains one of the most effective and widely used options — offering consistent dosing and rapid results.
Whether you’re new to TRT or simply want to make sure you’re injecting correctly, here’s a clear, safe, and medically sound guide to self-administering testosterone injections at home.
Why Testosterone Injections?
Injectable testosterone is commonly prescribed for:
Men with low testosterone (Low T) due to age or medical conditions
Women with hormonal imbalances impacting libido, energy, or mood
Patients who need consistent, therapeutic levels of testosterone
Individuals seeking a fast-acting, long-lasting TRT delivery method
Testosterone can be injected intramuscularly (IM) or subcutaneously (SubQ), depending on the prescription, dose, and patient preference.
Step-by-Step: How to Inject Testosterone Safely
⚠️ Important: Always follow your provider’s personalized instructions and dosage. This guide is educational and should not replace professional medical guidance.
1. Prepare Your Supplies
You’ll need:
Testosterone vial (e.g., testosterone cypionate or enanthate)
Alcohol swabs
1–3 mL syringe
Drawing needle (typically 18G)
Injection needle (typically 25G–27G for SubQ or 22G for IM)
Sharps disposal container
Cotton ball or gauze
2. Wash Your Hands Thoroughly
Start with clean hands and a sterile workspace. Hygiene is essential to prevent infection.
3. Draw the Medication
Wipe the rubber top of the testosterone vial with an alcohol swab.
Attach the drawing needle to the syringe.
Pull back on the syringe plunger to draw in air equal to your dose.
Insert the needle into the vial and inject the air (this reduces pressure).
Invert the vial and slowly draw the prescribed amount of testosterone.
Tap the syringe to remove air bubbles and push out any excess air.
Replace the drawing needle with the injection needle.
4. Choose the Injection Site
For Intramuscular (IM) Injections (typically for men):
Glute (upper outer buttock) – most common
Thigh (vastus lateralis muscle) – easy to reach for self-injection
For Subcutaneous (SubQ) Injections (commonly used for women or men on smaller doses):
Abdomen (1–2 inches from the belly button)
Thigh or outer arm (fatty area)
5. Clean the Skin
Wipe the chosen injection site with an alcohol swab and allow it to dry fully.
6. Inject the Testosterone
Hold the syringe like a dart for IM or at a 45–90 degree angle for SubQ.
Insert the needle quickly and smoothly into the muscle or fatty tissue.
Inject the testosterone slowly and steadily.
Remove the needle, apply light pressure with gauze or a cotton ball.
Do not massage the site.
7. Dispose of the Needle Safely
Place the used syringe and needle in a proper sharps container immediately.
How Often Should You Inject Testosterone?
Injection frequency depends on the form of testosterone and your
Men typically inject once or twice weekly (e.g., 100 mg weekly or 50 mg bi-weekly)
Women often receive smaller, less frequent doses (e.g., 5–10 mg weekly SubQ)
Your Vitality Sciences provider will monitor your labs and symptoms to adjust dosage and frequency as needed.
Common Mistakes to Avoid
❌ Reusing needles or syringes
❌ Injecting into irritated, bruised, or infected skin
❌ Skipping doses or adjusting dosage on your own
❌ Not rotating injection sites
