A Guide for TRT Self-Injection in the Thigh

Administering your own testosterone injection can be done safely and effectively when following proper steps. Below is a simple guide to help you perform the injection into your thigh (vastus lateralis muscle) with confidence and care.

Preparation
Step 1: Wash Your Hands

When performing any health related activity, it is good practice to always wash your hands before you begin. Wash your hands thoroughly with soap and warm water for at least 20 seconds.

Now, let’s take stock of all the materials needed to perform the injection. First, open your self-injection kit and locate the pre-filled syringe. Remove the block rubber stopper at the end of the syringe. Next, you will need remove the hypodermic needle from the packaging and attach it to the syringe. Now, open the alcohol swab. While the following items may not be included in your kit, you should prepare a gauze or a cotton ball, a bandage, and lastly a sharps container to dispose of your syringe. Now we are ready to prep the injection site.

Step 2: Prepare the Injection Site

Select an injection site on the outer middle third of your thigh. Clean the area with the alcohol swab, using circular motions from the center outward.

Step 3: Prepare the Medication

You should have a prepped, pre-filled syringe ready to go. Let’s check for air bubbles.

Step 4: Remove Air Bubbles

Hold the syringe with the needle pointing upward and gently tap the side to bring any air bubbles to the top. Slowly push the plunger to expel the bubbles, ensuring the correct dose remains in the syringe.

Step 5: Inject the Medication

Hold the syringe like a pencil, ensuring the needle is facing upwards. Use your other hand to gently stretch the skin at the injection site. This makes the injection smoother. Insert the needle into the thigh at a 90-degree angle in a swift, controlled motion.

Inject the Testosterone :

Slowly push the plunger to inject the testosterone into the muscle. Take your time to avoid discomfort and ensure proper absorption.

Withdraw the Needle :

Once the medication is fully injected, quickly and smoothly remove the needle. Immediately apply light pressure to the injection site with a sterile gauze or cotton ball.

Step 6: Post-Injection Care

Please note, never attempt to re-use a syringe or needle. Once you have completely injected the medicine, immediately dispose of the needle into a sharps disposal container. A sharps container can be purchased online or from a pharmacy. You can also use a hard plastic container such as a laundry detergent jug as a sharps container.

Once you have disposed of the syringe, gently massage the area to help the medication disperse and reduce soreness. If necessary, apply a bandage over the injection site.

Step 7: Alternate Injection Sites

Going forward, it is a good idea to alternate injection sites every time you administer the medication. This helps to minimize or prevent bruising or the occurrence of small nodules under the skin.

8. Aftercare

Watch for any signs of infection (redness, swelling, or warmth) at the injection site. If you notice any unusual symptoms, contact your healthcare provider. Rotate injection sites to prevent irritation or muscle discomfort.

When to Contact Your Healthcare Provider:

It is uncommon, but if you experience significant pain, bleeding, or signs of infection (e.g., redness, swelling, warmth) at the injection site, or if you experience any unusual changes to your health in the duration of your treatment, please do not hesitate to contact us.

You are now fully prepared to safely and effectively administer a testosterone injection into your thigh. Thank you for choosing SynergenX.
