Effects of Testosterone

The effects of testosterone are truly amazing, as there is almost nothing this primary androgen cannot do. Testosterone is an essential hormone for both men and women, and is one of the most important hormones we produce. Of course, men need ten times the amount women need, literally ten times the amount, but it remains essential to both sexes. To understand the effects of testosterone, we largely only need to understand the effects of low levels, for when we see what happens when levels fall we can see how vital testosterone is to our body. Then of course we have exogenous testosterone, the synthetic version and primary anabolic steroid. Let’s take a look at the hormone as a whole, and lead you to understanding the true effects of testosterone.


Testosterone is the primary androgenic hormone of an immense anabolic nature found in both men and women. By its nature, the effects of testosterone are largely responsible for our physical and mental well-being as well as our sexual function. When we do not produce enough testosterone we suffer in numerous ways that can be quite detrimental to our quality of life. No, the effects are not directly life threatening, but they can lead to many serious issues that are indeed life threatening if ignored. In many ways, low levels can be viewed as a gateway to serious complications. As stated, to understand the effects of testosterone we only need to see what low levels can cause, and such effects include:

Loss of Libido

Erectile Dysfunction

Loss of Muscle Mass

Loss of Strength

Increased Body-Fat

Loss of Energy

Loss of Concentration



As you can already see, testosterone is a very important hormone, but when levels remain low for an extended period of time you can really see how important this hormone is. As stated, low levels can be a gateway to many far more serious problems and they include:




High Cholesterol


Constant Muscle & Bone Soreness & Pains




You now have an idea regarding how important the effects of testosterone are, but what about synthetic testosterone or exogenous? Put simply, exogenous testosterone is the same as the testosterone you make. Once in the body, the body makes no notable distinguishing difference. The hormone will provide the same benefits as the naturally produced; however, with the introduction of exogenous testosterone, natural testosterone is suppressed. With the introduction of exogenous testosterone there is no need for natural testosterone production.

The idea behind exogenous use is quite simple, to provide enough testosterone to fill a deficiency or to enhance performance by increasing levels beyond the normal range. Through this enhancement we really see the effects of testosterone shine For instance, when supplementing to bring levels above baseline normal we enhance several various things within the body which include:

Increased Nitrogen Retention

Increased Protein Synthesis

Increased Red Blood Cell Count

Decreased Glucocorticoid Production

Increased Rate of Recovery

Increased Stamina

Increased Clarity of Thought

Increased Focus

Improved Sense of Well-Being

It doesn’t matter who you are, when you look at the above list it’s impossible to say the effects of testosterone are not welcomed. Through these effects are quality of life is enhanced, and that is the true effect we are all after regardless of our individual goals.

Adverse Effects

Of course, the use of exogenous testosterone is not without possible problems, “possible” being the key word. When we supplement with exogenous forms for the purpose of hormone replacement this is normally not much of a concern as we are only replacing what our body is no longer making. However, when we go beyond the normal or average range the adverse effects of testosterone can become an issue of concern. The reason for concern is the manner by-which testosterone converts into estrogen via the aromatase process. Through this conversion, as estrogen builds up five possible things can occur:


Water Retention

High Blood Pressure

High LDL Cholesterol

Low HDL Cholesterol

To prevent the adverse effects of testosterone, first and foremost we must keep our exogenous doses reasonable. Secondly, we must combat the estrogen conversion, and the best way to do this is through the use of an Aromatase Inhibitor (AI). AI’s do exactly what their name implies, they inhibit Aromatase. If the aromatase process is inhibited there is no buildup in estrogen, and further, by its nature an AI will actively reduce the amount of estrogen in the body making the adverse effects of testosterone of little to no concern.
