How Long Does Testosterone Stay In Your System: What You Should Know

Do you know what testosterone is? It is a hormone secreted by the testes, which is a part of the male body. However, you can see this hormone in lower levels among females.

​With that, you can also call testosterone as a male sex hormone. Moreover, testosterone is also a drug or medication that you can administer into the system. You can do it intramuscularly, transdermally, or subcutaneously.

​In men, it can be given off by the testes, which you can find in their scrotum. It is a primary hormone among men, but the ovaries of women also secret low quantities of testosterone.

But, you need to know that this particular hormone in men has a half-life, which depends on the type of testosterone. So, the question is how long does testosterone stay in your system?

Tests estimate that it takes an average person around 3 weeks (22 days to be exact) to clear testosterone enanthate from their system. While testosterone enanthate takes longer to clear than than propionate esters, it is cleared two times faster than cypionate esters.

Lets take a closer look at the various esters and their half-life.


Different Types Of Testosterone And Their Half-Life

Here are the various kinds of testosterone and their longevity:

Testosterone Propionate

Among all sorts of this hormone, testosterone propionate has the shortest life span. In fact, its longevity lasts up to 2 to 3 days. So, your body can remove the tiniest traces of this hormone, and it will no longer become present in your system for 11 to 16 ½ days.

​You can administer and introduce this hormone to your body via the means of injecting it. So, knowing that it only lasts for a while, you have to inject it every other day for efficiency.

​Today, you can use this hormone as an anabolic steroid, especially for weightlifters and bodybuilders. Also, you can treat testosterone propionate for deficiency of the male hormone.

​You need to remember that propionate is an additive responsible for testosterone’s life span. It usually lasts up to 2 to 3 days on an average. However, it may still last for four days at its peak longevity.

Testosterone Enanthate (Test E)

Commonly referred to as Test E, this may not be the longest lasting type, but this testosterone can serve many purposes. But, compared to testosterone propionate, how long does test e last in your system? The answer: in an average male it will last approximately 10 ½ days.

As with other forms of testosterone, it will also give you strength and facilitate the growth and development of muscles. Also, bodybuilders usually use testosterone propionate.​

Testosterone Cypionate

The third type and the testosterone with the longest half-life are the testosterone cypionate. The reason behind its longevity is that the chain of this hormone comes with eight carbon atoms.

​It is greater than the two other testosterone mentioned above. Also, it stays in the fatty tissues via your intramuscular injections.

​The way this kind of testosterone works is that it releases the hormone at the peak of 24 to 48 hours. Then, it goes to its average level for 12 days, with the longevity that lasts around three weeks or 21 days.

That way, this hormone has an advantage. You do not have to inject this type of hormone as often as you have to with the previous kind.

Unlike other testosterone mentioned previously, you do not have to inject it as often as you do with test e for example. You need just to administer it once every week. So, it is least painful and cost-efficient route to go when you want an injectable testosterone.

Factors Influencing Longevity Of Testosterone

When it comes to the half-life, there are a few factors you need to know. These include:

Features Of Your Body

Although documents are supporting the lifespan of testosterone, you need to remember that it will still depend on the chemistry of your body. With that, other people’s testosterone will last shorter or longer than the half-life suggested.

​Some of the features that may impact your testosterone longevity are age, body mass, plasma proteins, dietary intake, metabolism, renal and hepatic function. Once the ranges change, there’s a chance that it can influence the absorption rate and full life span of the hormone.


Aside from biological features, one of the factors that affect the half-life of testosterone is the dosage. It plays a vital role in dealing with the lifespan of this hormone and how long it can remain in your body.

The more you inject testosterone into your system, the longer it can stay.

​But, you may administer some of these types on a day-to-day basis. On the other hand, you may inject the other sorts every other day. For hormones with longer life spans, you may give it once in each week.

Type Of Administration

While the intravenous route is often the method most people prefer, you still have seven other ways to inject testosterone. Here are some ways you can give this hormone:


While this is a choice that would fit those people who have a phobia of needles, selecting this route may mean that you can absorb less testosterone. Also, the hormone may also be disregarded faster in your system.


It is a method of administering testosterone in the way of patches. You can just stick or tape it on your skin. Also, this is one way you will not feel much pain when you want to inject this hormone. However, the half-life is a downfall because it can only last up to 1 hour and 18 minutes.

Injecting In Muscles

The entire durations indicated above are from injectable testosterone. It may be painful. However, it is such an excellent way to give testosterone because its lifespan may be longer than the other forms of testosterone.


By now, you may have realized how tricky your hormones, especially your testosterone can be to manage. A little imbalance may cause a few health effects and changes. A far safer alternative to start off with would be to use a mass builder, like Serious Mass, to gain weight and muscle more naturally.

However, if you are low on testosterone, or you feel that your levels have dropped in recent years, this is normal. You can expect that your T-level may decrease as you get older. In fact, that’s the reason why a lot of athletes and bodybuilders inject testosterone in their systems.

​Thus, it is crucial that you know the type of testosterone and the half-life of each. That way, you won’t ever come to the point of overdosing the hormone. Also, by doing so, you won’t ever experience low levels of testosterone.
