About Testosterone Injections

Testosterone is most commonly used in the United States as the cypionate and the enanthate esters. While doctors often administer both forms of testosterone injection weekly, some physicians administer testosterone as infrequently as every two weeks and in some cases every month, the pharmakinetics (absorption and distribution of testosterone by the body) of these hormone drugs show that weekly testosterone injections are best if the most consistent blood-levels of the drugs are desired.

Weekly injections of testosterone may therefore, be a superior treatment regimen for most men with Low T symptoms. When testosterone injections are adminstered bi-weekly or monthly, many patients complain of a noticeable decrease in energy, libido, clarity of thought and mood by the time the two or four week administration occurs. For this reason many effective testosterone treatment programs will comprise weekly testosterone injections.

Testosterone Injection Dosage: One study stated that 140 mg. of testosterone cypionate and testosterone enanthate produced similar blood levels after injection, and stated that heightened blood levels decreased to basal levels by day 10. With higher testosterone doses the duration appears to increase a little with another study stating that with an injection of 200 mg. of testosterone cypionate blood levels reached basal levels by days 13 to 14.2


Although the decline in testosterone production as men age (“andropause”) is not as dramatic as the drop in women’s estrogen production with the onset of menopause, testosterone decline is a serious issue for many older and aging men. Among other problems, declining testosterone production is strongly associated with impotency, erectile dysfunction and libido problems.



Anti-aging benefits that have been associated with testosterone replacement therapy may include increased libido and sexual potency; improved erectile function; improved mood and increased feelings of well-being; decreased fatigue; increased energy and red blood cell count; reduction of LDL cholesterol and overall cholesterol levels; cardiovascular and brain function; and strengthening of the muscles and bones. Results of research published in 2002 revealed that men who have higher levels of “bioavailable” testosterone – testosterone that is not bound to protein – appear to perform better on tests of mental performance than men with lower levels of the hormone.

Symptoms of testosterone deficiency include: reduced libido and low sex drive; always feeling tired, fatigued or a decrease in physical stamina or endurance; difficulty in having or maintaining erections (erectile dysfunction – ED), memory impairment or Alzheimer’s; weight gain and body softness; depression, irritability and anxiety; increased risk of heart disease or diabetes; decreased muscle and bone mass; inability to sleep – insomnia, night sweats or hot flashes; feeling unmotivated with a decline in drive, ambition and sociability.


Better and more frequent sex. Increased energy, endurance and vitality. More muscle and improved fitness. Improved health, mood and quality of life. Greater mental agility and concentration. Testosterone therapy can provide life-enhancing benefits for men with low levels of testosterone when they increase their testosterone level with testosterone injections.


Testosterone replacement needs to be managed by a physician to ensure that a patient receives only enough of the hormone to replenish lost levels. Many forms of administering testosterone have been developed, including intramuscular injections; suppositories; transdermal patches attached to the midriff, thigh, or arm, as well as to the scrotum; oral micronized capsules; sublingual lozenges; bio-identical testosterone creams and gels.

Advantages of injectable testerosterone versus creams, gels and patches:

  • Infrequent dosing, every two to four weeks or longer instead of daily or weekly
  • Dramatic physical feeling immediately after the injection; many men like the “boost” and marked increase in sexual desire and performance
  • Testosterone injections is one of the lower cost replacement therapy options available

(Oral administrations for testosterone replacement seem to be the least effective method and have implications for the liver.)


Testosterone therapy including injections, creams, patches, pellets and gels should only be administered under strict medical guidance after a comprehensive blood test and physician’s evaluation.


If testosterone replacement is administered to men with normal or near-normal levels of the hormone, any number of side effects may occur. Testosterone treatment should only be considered in men with low testosterone levels. Most notably, excess doses of testosterone may inhibit the body’s ability to produce testosterone. Testosterone replacement treatment carries with it the risk of stimulating both benign and malignant prostate tumor growth. In addition, because it can reduce HDL cholesterol levels, testosterone replacement may be associated with an increased risk of coronary artery disease.
