Testosterone levels peak two to three days after the injection and then slowly decrease until the next dose of the hormone is administered. There are also testosterone patches that men can use. The amount of time it takes for a testosterone injection to take effect will vary from patient to patient. Some men start to notice improvement within a few weeks, while others need more time for treatment to bring about noticeable changes.
As with any medical treatment, response times are different for each individual. Improvements in insulin sensitivity levels can be seen one week after undergoing testosterone replacement therapy. A decrease in triglycerides can be seen after 4 weeks and 3 months and extends to 12 months. Researchers have also observed that total cholesterol levels decrease between 4 weeks and 3 months.
Studies that investigate the effects of testosterone should consider this schedule in order to design the duration of the studies and to have quantifiable measures available. Effective, life-changing, and surprisingly affordable, testosterone therapy can get you back to being your best self. If you know your total testosterone reading from a previous blood test, enter the results on the left above to see if your testosterone levels are normal. After the administration of testosterone, there is a decrease in fat mass and an increase in lean body mass and the net result is often, but not always, that total body weight does not show significant changes.
Treating hypogonadal men with testosterone is rewarding, both for patients and for the doctor. The temporal course of the spectrum of effects of testosterone shows considerable variation, probably related to the pharmacodynamics of the testosterone preparation. And, understandably, this is one of the things men most look forward to with testosterone replacement therapy. While the effects of testosterone have been described in detail, relatively little attention has been paid to the time it takes for these effects to occur and achieve full expression.
The only legal way to receive testosterone therapy in the United States is with a prescription from a doctor. However, testosterone deprivation and its time-dependent effects may be totally different from the onset of the action of testosterone in testosterone treatment, even in the same parameter. Numerous studies attest to the ability of testosterone to build muscle and increase strength and athletic performance. Patients receiving testosterone replacement therapy are well aware of the debilitating effects of low testosterone levels.
Like granules, testosterone injections tend to peak in serum between 24 and 48 hours after injection, and then begin to decrease until they reach low normal levels (. One possible solution to this would be to replace the “universal threshold” with the “percentage increase” in circulating testosterone achieved with replacement therapy. That's why when I talk to those who have difficulty seeing the effects of adding testosterone to their diet, I always ask them about their protein intake and it never surprises me to learn that their daily protein intake is nowhere near what it should be. Ideally, they should measure at which serum testosterone levels all androgen-dependent biological functions are restored.
