Here’s your Patient Guide to help you with self-administering injections and to help answer your most frequently-asked questions.

Testosterone Injections

We provide testosterone replacement options for patients through Intra-muscular Injections (IM) and a topical cream. Since the IM method in the glutes is most popular among patients, we’ll go over the most essential information for how to self-administer injections.

Supplies you'll need

In order to prevent contamination and ensure safe administation of your testosterone, it's important to use two separate syringes for the extraction and injection of the medication. All TRT patients that choose to self-administer receive their supplies for 8 weeks. We also include the option of receiving injections by one of our RNs on site at our two Miami locations.

How to Inject Testosterone

1. Find out the amount of medication to use

Find the correct dosage to use by reviewing your patient documentation, or call us at 786-899-4514 or 305-330-6900

2. Use sterile supplies with correct specifications

It’s important to use the sterile needles we provide you that have the exact specifications needed to correctly administer testosterone. Because testosterone is oil-based, a needle with thicker gauge like 21g is required to draw up the dosage from the container. We also provide you with a 22g needle to replace the 21g needle when you’re ready to inject. Remember to wash and sanitize your hands!

3. Draw up dosage

The doctor will have given you a recommended dose – determine the volume of your dose in relation to the concentration of your testosterone. For instance, if the doctor recommends a dose of 100 mg, you’ll want 1 ml of a 100 mg/ml testosterone solution or ½ ml of a 200 mg/ml solution. To draw up your dose, first draw air into your syringe equal to the volume of your dosage. Then, wipe the top of the medication bottle with an alcohol wipe, insert your needle through the lid and into the medication, and push the air from your syringe into the bottle. Turn the bottle upside down and draw out the exact dosage of testosterone.

Injecting air into the bottle raises its internal air pressure, making it easier to draw the medication into the syringe. This is especially important with testosterone, which can be difficult to draw because it’s so thick.

4. Aspirate Syringe

Injecting air bubbles into a person’s body can cause a serious medical condition called an embolism. Because of this, it’s very important to ensure there are no air bubbles in the syringe when you inject the testosterone. Do this via a process called aspiration. See below for instructions:

Hold the syringe with its needle uncapped and pointing up in front of you.

Look for air bubbles in the syringe. Flick the side of the syringe to get these bubbles to rise to the top.

When your dosage is bubble-free, slowly depress the plunger to force the air at the top of the syringe out. Stop when you see a tiny drop of medication come out of the tip of the syringe. Be careful not to squirt or spray a significant portion of your dosage onto the floor.

5. Prepare Injection Site

Testosterone injections are typically intramuscular – that is, given directly into a muscle. Two relatively easy and accessible sites for intramuscular injection are the deltoid (upper arm) or the glut (upper back portion of the thigh, ie, the butt cheek). These aren’t the only places that testosterone can be injected, but they are by far the most common. Whichever of these sites you choose, take a sterile alcohol pad and wipe the immediate area around where you intend to inject. This will kill bacteria on the skin, preventing infection.

If injecting into the glute or buttocks, choose an injection site in the top outside section of the glute. In other words, pick a site either in the top left corner of the left glute or the top right corner of the right glute. These site have the best access to muscle tissue and allow you to avoid hitting nerves and blood vessels in other parts of the glute.

6. Perform the injection

Hold your loaded syringe like a dart at a 90-degree angle above the sterile injection site. Quickly plunge it into the flesh. Before depressing the plunger, draw back on it slightly. If you draw blood into the syringe, remove the needle and choose a different spot, as this means you’ve hit a vein. Inject the medication at a steady, controlled pace.
