Testosterone is the primary male hormone responsible for sexual characteristics in men. Males with low testosterone levels cannot perform in the same way they did when their levels were normal. Besides libido, testosterone affects sperm development, strength, bone density and muscle mass. Injectable testosterone, made from bioidentical hormones exactly like those created by the body, can rejuvenate men and address the age-related deficiencies. Most men effectively absorb testosterone through the skin, making topical application easy and effortless.

However, in many cases, optimal levels of testosterone, necessary for reduction of cardiovascular disease as well as for physical well-being, cannot be achieved. The alternative is to bypass the skin using injectable testosterone.

Injectable testosterone therapy helps restore a man’s physical, sexual and emotional well-being. Men will notice improved sexual function along with mood uplift and more energy. These results are not instantaneous but slowly occur as treatment continues. Contact a doctor right away if you are interested in learning more about how this treatment may benefit you.


The majority of testosterone develops in the testicles, although lesser amounts are produced in the adrenal glands. Testosterone is produced primarily during sleep. As men grow older, their testosterone levels decline.

After age 30, testosterone levels decline by approximately 1 percent annually. While these changes are gradual, eventually signs of low testosterone appear. These may include:

  • Body hair loss
  • Cognitive decline
  • Depression
  • Erectile dysfunction
  • Infertility
  • Insomnia
  • High blood pressure
  • Less energy
  • Loss of libido
  • Loss of muscle mass
  • Moodiness
  • Weight gain

Not all of these conditions occur because of low testosterone levels, which is why thorough testing is required to pinpoint the cause. Testosterone levels are detected primarily by blood testing although urine and saliva sampling can be used as well.

Other causes besides aging can cause testosterone levels to drop. These include certain medications, substance and/or alcohol abuse and traumatic brain or neurological injury. That is why a doctor performs a thorough medical assessment prior to beginning injectable testosterone treatment.

Injectable Testosterone Treatment

Patients are instructed to self-administer testosterone by injection under the skin (subcutaneously) twice weekly using a painless microneedle. Alternatively, deeper intramuscular injection once or twice monthly which has been the historical route of administration.

Implantation of testosterone pellets into soft tissue allows the medication to slowly enter the bloodstream but absorption is erratic and varies over time. Oral testosterone is available but it is not well absorbed by the body. Topical administration using creams or patches should be the initial approach to therapy.

Patients are carefully monitored to ensure testosterone remains at optimal levels. Changes to the medication are made periodically as needed. Along with injectable testosterone treatments, the doctor or nutritionist will recommend a specific diet and exercise plan to maximize the benefits of hormone therapy.

Risk Factors and Side Effects

Men diagnosed with active cancer, uncontrolled heart disease, diabetes, liver, or kidney disease should not receive injectable testosterone. Patients should inform their doctor about all of their medications including over the counter supplements.

Most men tolerate injectable testosterone well, but side effects can occur. A doctor should be contacted immediately if someone experiences any of the following symptoms:

  • Chest pain
  • Constant erection
  • Edema
  • Fast weight gain
  • Shortness of breath
  • Skin discoloration
  • Urination problems
  • Changes in testicle size
