Testosterone Injections: How To Increase Your Testosterone Levels

Testosterone injections can help restore normal testosterone levels, which support the development of male characteristics, enhance muscle mass and bone density, increase libido, and boost energy and mood. These injections are often used to treat erectile dysfunction and low testosterone levels in men.

If you’re considering testosterone injections in Pennsylvania, BOOK A CONSULTATION at Regen Doctors. A prescription and recent bloodwork (within the last six months) are required. If you haven’t had bloodwork done, a medical provider will order it for you.

Types of Testosterone Injections

There are many types of testosterone injections, each with different absorption rates and dosing schedules. The most common types are:

• Testosterone Cypionate (Depo-Testosterone): One of the most widely used forms, cypionate has a longer half-life, typically requiring injections every 1 to 2 weeks. It provides steady testosterone levels but may cause fluctuations between doses.
• Testosterone Enanthate (Xyosted): Similar to cypionate, enanthate is injected every 1 to 2 weeks. It’s commonly used for testosterone replacement therapy (TRT) and offers a slightly faster absorption rate. Xyosted is an auto-injector version designed for at-home use.
• Testosterone Undecanoate (Aveed): A long-acting injectable form that requires fewer injections typically every 10 to 12 weeks. It provides more stable testosterone levels over time but must be administered in a medical setting due to potential risks like pulmonary oil microembolism or POME.

How Does Testosterone Injection Work?

Testosterone is a male sex hormone responsible for the development of male sexual characteristics such as a deep voice and body hair. While testosterone levels peak during puberty, they tend to decline after the age of 30, which leads to low sex drive and erectile dysfunction in some men. 

Testosterone injections deliver synthetic testosterone into the muscle, where it’s absorbed into the bloodstream. This restores testosterone levels, improving energy, muscle mass, mood, and overall well-being.

Injections are typically given weekly or biweekly. Once in the bloodstream, testosterone binds to androgen receptors, triggering key functions like red blood cell production, protein synthesis, and fat metabolism. Because testosterone levels fluctuate after each dose, regular monitoring ensures proper dosing and minimizes side effects.

Where to Inject Testosterone Injections

There are 2 methods for giving testosterone injections.

• Intramuscular injections: This method involves injecting the medication directly into a muscle for rapid absorption. It can be injected into the thigh or buttocks.
• Subcutaneous injections: This method involves injecting the medication into the fatty tissue just beneath the skin, above the muscle layer. It can be injected into the stomach, thigh, or upper arms.

How to Inject Testosterone

Testosterone is to be injected into a muscle under the skin by a doctor or nurse in an office setting or clinic. You may also choose to self-inject at home but it’s important to consult your provider for guidance. 

For intramuscular injections, insert the needle at a 90-degree angle into the thigh or glute. For subcutaneous injections, use a 45-degree angle in the lower abdomen or thigh. Insert the needle quickly, inject slowly, then remove it and apply light pressure. Dispose of the needle in a sharps container and rotate injection sites to prevent irritation. Monitor for swelling, redness, or pain.

What is the Normal Dose for Testosterone Injection?

The normal dose for testosterone injections depends on your needs and how your body responds. For testosterone replacement therapy (TRT), the usual starting dose is 50–100 mg of testosterone cypionate or enanthate per week or 100–200 mg every two weeks. Testosterone undecanoate (Aveed) is given less frequently, around 750 mg every 10–12 weeks. Your provider will determine the right dose based on your bloodwork, symptoms, and treatment goals. 

When Does Testosterone Peak After Injection?

Peak levels of testosterone after injection vary based on the type of testosterone and the method of administration. Generally, peak testosterone levels are reached between 24 to 72 hours after the injection, although some may peak slightly earlier or later.

For testosterone cypionate, a widely used form of testosterone injection, the typical timeline is as follows:

• 24 hours – Rising testosterone level
• 48-72 hours – Peak testosterone level
• 3 to 7 days –  Gradual decline of testosterone level
• 1 to 2 weeks – Return to baseline testosterone level

How Long Does It Take for Testosterone Injections to Work?

Testosterone injections don’t work overnight, but most men start noticing changes within a few weeks. Energy levels, mood, and libido often improve within 3 to 4 weeks. Muscle growth, fat loss, and strength gains become noticeable after 6 to 12 weeks. More significant changes, like increased bone density and body composition improvements, can take 6 months to a year.

What are the Side Effects of Testosterone Injections?

Potential side effects of testosterone injections include:

• Bruising, pain, bleeding, or swelling at the injection site
• Prostate enlargement
• Weight gain
• Increased appetite
• Hot flushes
• Acne
• Hoarseness
• Deepening of voice

How Much Does Monthly Testosterone Injection Cost?

The cost of testosterone injections varies based on the type, dosage, and whether you have insurance. Without insurance, testosterone cypionate or enanthate typically costs $30 to $150 per month, while testosterone undecanoate (Aveed) is much pricier, ranging from $1,500 to $4,000 per injection every 10–12 weeks. 

Insurance may reduce costs significantly, but coverage varies. Prices also depend on whether you self-inject or receive injections at a clinic. To get exact pricing and insurance details, check with Regen Doctors.
