    Injectable Testosterone
    FAQs

    Contact Support

    How does injectable testosterone work?

    Injectable testosterone delivers testosterone directly via at-home injections. It's the most studied and proven form of TRT, producing strong, consistent testosterone levels with decades of clinical research behind it.

    How often are injections given?

    Most protocols involve 1–2 injections per week, depending on your prescribed dose and how your body responds. Your Longevity clinician will determine the optimal frequency for you.

    Are testosterone injections painful?

    Most men find injections virtually painless. Longevity offers subcutaneous injections, which are just as effective as intramuscular and often more comfortable. You'll use small needles and receive clear instructions for safe at-home self-injection. While the first injection may feel daunting, most customers find it gets easier over time.

    How is Longevity injectable testosterone different from other providers?

    Longevity has specially formulated our injectable testosterone with MCT oil, which is less viscous, smoother to inject, has a lower risk of inflammation, and absorbs better. Many other providers use grapeseed, sesame, cottonseed, or castor oil - none of which offer the same performance and quality.

    When will I notice results from injectable testosterone?

    Injectable testosterone provides slow release with all-day coverage after injection. Most men notice improvements in energy, mood, libido, and training recovery within the first few weeks, with full benefits building as levels stabilize over 2-3 months.

    What are the potential side effects of injectable testosterone?

    Side effects may include acne or oily skin, changes in libido, mood fluctuations, fluid retention, increased blood pressure, and elevated hematocrit, hemoglobin, or PSA levels—this is why lab monitoring is important. Regarding hair loss: testosterone can convert to DHT, which may accelerate male-pattern hair loss in men who are genetically predisposed. If this is a concern, your clinician can discuss options like dutasteride.

    Will injectable testosterone affect fertility?

    Yes. Like other forms of TRT, injectable testosterone can suppress natural testosterone production and sperm production, which may impact fertility markers. If preserving fertility is a priority, discuss alternative options with your clinician.

    Do I need lab work for injectable testosterone?

    Yes. Lab testing is required to confirm eligibility, guide dosing, and monitor key health markers over time. If you have bloodwork from the last 6 months that includes Total Testosterone, SHBG (or free testosterone), LH, PSA, and Hematocrit, you can upload your results during the sign-up process.
