Testosterone Injections For Low-T

Testosterone Injections For Low-T

It has been well-documented that testosterone levels decrease after age 30, and overall the population is aging! Nearly 55 million or 16.3% of Americans are over the age of 65 (U.S. Census Bureau, 2004). Testosterone has many beneficial effects, such as increasing muscle mass and strength, increasing bone density, stimulating libido and spontaneous erections, improving energy, mood, and motivation, increasing red blood cell production, and restoring hair regrowth. Most men do not want to suffer from the adverse effects of decreased testosterone levels just because they have a few years under their belt. Navigating through social media sites such as Reddit, you can easily see that there is great interest in buying testosterone injections online. Men want to know how to get a prescription for testosterone replacement therapy and where the best place is to buy testosterone online.

Symptoms Of Low Testosterone

The symptoms of low testosterone can be fairly non-specific, such as

  • reduced muscle mass or bone density
  • depression or changes in mood
  • weight gain
  • fatigue
  • irritability
  • decreased ability to sleep
  • difficulty paying attention or focusing.

They can also be more specific for a hormone deficiency and include

  • low sex drive
  • erectile dysfunction
  • decreased spontaneous erections
  • enlarged breasts (gynecomastia)
  • infertility

Even these more specific symptoms can be found in several medical conditions. Before considering where the best place to get testosterone injections online is or how to get a prescription online, you need to verify that low testosterone levels are the cause of your symptoms. The only way to know for sure that low testosterone levels may be contributing to your health concerns is to get a panel of blood tests to test for low testosterone.

Recommended lab tests for men with symptoms of low testosterone:

  • Testosterone levels: At least two blood samples should be taken in the morning after fasting. Testosterone levels naturally fluctuate throughout the day.
  • Sex hormone-binding globulin (SHBG): Testosterone circulates in the blood bound to sex hormone-binding globulin, bound to the protein albumin, or unbound. Only the free testosterone plus the testosterone bound to albumin is available to act on target tissues. Free-testosterone and SHBG should be checked to determine the level of biologically active testosterone.
  • Luteinizing hormone (LH) and follicle-stimulating hormone (FSH): LH and FSH are hormones secreted by the pituitary gland. LH stimulates the testes to produce testosterone, and FSH is involved in sperm production. Measuring these two hormone levels can help distinguish between low testosterone originating from a problem in the brain or pituitary gland from one in the testes.
  • Prolactin: Prolactin is a pituitary hormone that stimulates milk production in the female. Abnormal levels of prolactin can indicate a problem in the pituitary gland.
  • Additional lab tests: Hemoglobin level to check for red blood cell count. Lipid panel to check for cardiovascular risk. PSA to screen for prostate cancer. A baseline level of free estrogen (AACC, 2020). When testosterone is supplemented, some will be converted to estrogen. A baseline level of highly sensitive estrogen will help determine how high the conversion rate is.

Lifestyle changes can affect your testosterone levels as well. Getting adequate sleep, managing stress, eating healthy, watching your weight, and exercising can all affect testosterone levels. Make sure you are getting the vitamins and minerals the body uses to produce testosterone. Vitamins, such as vitamin D, are essential for producing hormones such as testosterone.

Treatment Options

Hypogonadism or low testosterone levels affect up to 4 million American men, yet only about 5% of men with documented low testosterone levels receive treatment (Seftel, 2005). The American Urological Association recommends prescribing testosterone replacement therapy only for men who meet the clinical and laboratory definition of low testosterone.

Syringe and Vials

There are many ways to get testosterone into the body, but the only one that has been around a few decades and has been documented to work is testosterone injections. Testosterone cypionate is the most commonly prescribed testosterone injectable in the United States. Each injectable testosterone product has testosterone attached to an ester. The effect of binding testosterone to an ester is to change its half-life. The half-life of testosterone cypionate is approximately seven to eight days (FDA, n.d.). The typical dose for testosterone cypionate is 100mg to 200 mg injected intramuscularly every two weeks. The longer the period between injections, the more fluctuation there is in hormone levels and, therefore, the more likely there are to be side-effects.

How To Get A Prescription For Testosterone Online Or Locally

Testosterone injections require a prescription as testosterone is a hormone and can have effects on many organ systems in the body. Testosterone replacement therapy should not be prescribed without documented symptoms of low testosterone and lab results, indicating that low testosterone levels are the source of your symptoms. There are several physician and clinic options men can choose from when determining how to get a prescription for testosterone injections and the best place to buy testosterone, whether locally or online.

Primary Care Physician: The first option is to visit your primary care physician. Your doctor will have your medical records and know your past medical history and any conditions he or she is currently treating you for. Primary care physicians cover pretty much all fields of medicine. They are the gatekeepers to more specific medical specialties. Therefore, you may find that they refer you to a specialist, such as a urologist if they determine you have low testosterone levels.

Urologist: A urologist is a specialist who treats conditions of the urinary system in both males and females and the reproductive system in the male. A urologist will know the latest treatment options and research findings for treating hypogonadism or low testosterone levels. Urologists, in many areas of the country, are in short supply, so you may find that you have a long wait before you can get in to see one.

Endocrinologist: An endocrinologist is a specialist who deals with disorders of the endocrine system. The endocrine system includes all the hormones in the body and their effects on target tissues. Endocrinologists will be well-informed on testosterone replacement therapies, but like urologists, it may take a while to get to see one.

Testosterone Injections

The health care provider you choose will review your lab results, take a history of your symptoms and past medical history, and discuss the risks and benefits of testosterone replacement therapy with you. If you and your health care provider determine that testosterone replacement therapy is a good option for you, you will receive a prescription for testosterone intramuscular injections.

The recommended dosage for testosterone cypionate is 100 to 200 mg injected intramuscularly every two weeks. The exact dosage you will be prescribed will depend on how much testosterone supplementation you will require to bring your testosterone levels to a normal level. You can expect that you will stay on testosterone for about three months before getting follow-up labs to evaluate your body’s response to treatment.

Where Is The Best Place To Get A Prescription For Testosterone Online?

The best place to get a testosterone prescription online is a men’s health clinic that requires a panel of blood work to verify that low testosterone levels are the cause of the symptoms you are experiencing, followed by an appointment with a licensed medical provider in your state who can review your symptoms and your lab work, and if appropriate, write you a prescription for testosterone cypionate injections. Invigor Medical follows this strict protocol so you can ensure that the treatment you are receiving follows the current best practices for treating low testosterone.

What You Should Avoid Online

Several types of testosterone boosting supplements are sold online without a prescription. The herbal and nutrient-based supplements are marketed as testosterone boosters. These products are not regulated by the FDA and can contain a myriad of ingredients. Most contain horny goat weed, saw palmetto, and fenugreek (Regan et al., 2011). These products are advertised to supplement testosterone without the high cost of prescription medications and are prominently displayed on websites and online pharmacies (Balasubramanian, et al., 2019). Physicians can point to cases where these testosterone imposters have included banned substances, including steroids, which resulted in serious adverse effects for consumers (Geyer et al., 2008). 

Only 195 of the studies examining the ten most common ingredients in these products were conducted in humans. Among those that conducted human studies, most ingredients had either a questionable effect or were ineffective at actually raising testosterone levels (Balasubramanian, 2019).


The diagnosis of low testosterone is made when men have the expected symptoms of low testosterone levels combined with lab results that indicate that low testosterone is the cause of these symptoms. Testosterone replacement for men with medical conditions that lead to the decreased production of testosterone, hypogonadism, is well-established. Supplementation for men with age-related or lifestyle induced decreases in testosterone is not as well-established.

How to get a testosterone prescription online is fairly clear. Verify that your medical clinic is following the guidelines for diagnosing and treating testosterone deficiency. Ensure that they have a history of treating men with testosterone deficiency, so you know they are current on what the latest research shows are best practices for testosterone supplementation. Testosterone injections have been used for decades to treat low-T. Hence, the best place to buy testosterone injections online is a U.S. based, licensed pharmacy that requires a prescription from a licensed medical provider before dispensing the medication.
