Introduction – How Steroid Drug Testing Works
The key to understanding anabolic steroid detection times lies
in the ability to learn about and understand how drug testing
for anabolic steroids and performance enhancing drugs works, and
what exactly are the factors involved in affecting anabolic
steroid detection times. Drug testing for anabolic steroids and
related performance enhancing drugs is one of the most
misunderstood topics and concepts by both the average individual
as well as those athletes, bodybuilders, and individuals who
actually use anabolic steroids. There are in fact a few popular
misconceptions in regards to anabolic steroid testing.
The first misconception is that general drug testing holds the
capability to test for anabolic steroids. This is wrong. Testing
for anabolic steroids requires a very specific test, requiring
the use of very sophisticated, very expensive, and advanced
equipment. Being that anabolic steroids are hormones that are
native to the human body as well as synthetic analogues of these
same hormones, the methodology and pathways to detecting
anabolic steroids and the individual steroid detection times are
all very different from the methodology used to detect commonly
used recreational drugs such as cocaine, marijuana,
methamphetamine, etc. These recreational drugs are, for all
intents and purposes, compounds that are foreign to the body and
operate through very different mechanisms and pathways than
hormones and anabolic steroids do. In addition to this, the
equipment and procedures required for the detection of common
recreational drugs are very cheap and cost effective in
comparison to anabolic steroid testing, which is why they can be
employed far more frequently and on a much wider scale.
The second misconception, which is almost as common as the first
mentioned misconception, is that the general testing procedure
involves urinating in a cup (or having blood drawn) and having
that sample inserted into some monolithic machine that will
ubiquitously ‘detect’ and ‘know’ every single substance and
anabolic steroid in that sample. This is very wrong. Almost the
whole process of steroid detection requires human interaction at
every level, and the investigation into steroid detection
involves some sort of person at every minute of the testing
procedure. Advanced machinery and equipment is used, but humans
must do the investigatory methods and operate the machines at
every step of the procedure and it must be conducted
meticulously, which is why the whole process is very prone to
error – human error. The testing procedure for anabolic steroids
and other performance enhancing drugs is so complex and
expensive that there are in fact only a handful of laboratories
in the world that can conduct this testing.

Furthermore (and perhaps the most important message to take home
in this article), anabolic steroid testing involves the testing
for all known anabolic steroids and their analogues. This must
be repeated again as it is very crucial for the reader to
understand: anabolic steroid testing involves the testing for
all known anabolic steroids and their analogues. This means that
in order to catch an athlete or individual using anabolic
steroids, his or her urine or blood sample must be sampled and
assayed for every single anabolic steroid in existence that is
known until it is narrowed down to whatever the person being
tested for is using (or has recently used). This is where
steroid detection times also play a large role, which will be
expanded upon much further very shortly. Most anabolic steroid
testing occurs via urinalysis (analysis of the individual’s
urine). The second most popular or frequent method of testing is
via a blood analysis. A third testing method involves the
testing of hair samples, but this is not normally reliable for
anabolic steroids and is usually done for the testing of
recreational drugs.
The very expensive procedures (and equipment) for the purpose of
anabolic steroid detection involves the use of gas
chromatography-mass spectrometry, and even liquid
chromatography-mass spectrometry[1] [2] [3] [4]. These are all
extremely expensive procedures and pieces of equipment, costing
millions of dollars in order to test perhaps only a handful of
individuals.
Anabolic Steroid Metabolites
Urinalysis is by far the most reliable testing method, as the
amount of time an anabolic steroid or drug remains detectable in
one’s system is the longest in an individual’s urine, especially
in the case of the metabolites of that compound. While blood
testing is also quite reliable, it falls short of urinalysis due
to the fact that anabolic steroids undergo extensive
biotransformation through the liver (hepatic biotransformation)
as well as through the kidneys (renal). Metabolites are the
products of the body’s metabolism of various substances and
compounds (in this case, anabolic steroids). The metabolism of
compounds in the body, such as anabolic steroids, results in
changes to the original chemical structure (or it can also
result in byproducts). These changed molecules are eventually
excreted from the body in urine (and a much smaller percentage
in feces), which is where they can be identified and detected.
If a metabolite of a known substance is detected in an
individual’s urine, there is a very good chance that that
individual was indeed utilizing that known substance of which
the metabolite formulated from. Almost all anabolic steroids,
chemicals, drugs, and even components of food are metabolized
into different compounds than their original form that they were
ingested or administered in. However, a small percentage of some
compounds might be excreted from the body in its original form,
un-metabolized, and a small percentage overall of all ingested
or injected compounds will be excreted in its original form.
This is where steroid detection times play a very large role.
Because the detection of anabolic steroids in testing procedures
plays such a central and pivotal role, the shortcomings of blood
testing lies in the fact that because anabolic steroids are
primarily metabolized through the hepatic and renal (liver and
kidney) pathways, metabolites rarely linger around in blood
plasma for very long, if at all. Often times, they cannot be
detected in blood and can clear the bloodstream far too quickly
and far too easily. This is where the advantage lies in
urinalysis. The formation of metabolites in the body is merely a
part of the natural biochemical processes of the body using,
changing, degrading, and eliminating compounds in the body
through their life cycles. An example of some metabolites of
Testosterone include: Epitestosterone (an inactive epimer of
Testosterone that is analyzed in urine to detect the use of
supraphysiological levels of Testosterone by an athlete),
Dihydrotestosterone (a metabolite of Testosterone that serves a
slightly different purpose in various tissues), and even
Estrogen can be considered a metabolite of Testosterone. Both
Dihydrotestosterone and Estrogen are metabolized from
Testosterone via enzymes that are responsible for their
conversions from Testosterone.
Anabolic steroid detection times are more closely related to the
metabolites of the anabolic steroids rather than the anabolic
steroids themselves, as these metabolites are what linger around
in the body and in the urine for longer periods of time than the
original anabolic steroid that was used. For example, while an
athlete that uses bodybuilding dosages of Testosterone might
test positive for Testosterone through a blood or urine test
merely by way of the fact that very high Testosterone levels
would be seen in his blood or urine, the question remains as to
how this athlete would test positive for Testosterone use after
he has stopped using it? The answer to this is key to
understanding steroid detection times, and while this
hypothetical user of Testosterone might have stopped use long
before a urine test so that high Testosterone levels might not
be found, Epitestosterone levels are a telltale sign, as an
obscenely and abnormally high Testosterone:Epitestosterone ratio
would be seen in this individual’s urine. A normal individual
typically has a ratio of 1:1, while some Testosterone using
athletes have been found to have a 1.15:1 or even a 3.71:1
ratio. This is what would give away the fact that bodybuilding
doses of Testosterone were used, as very high levels of the
metabolite Epitestosterone would linger in the individual’s
urine sample. This analysis of Testosterone:Epitestosterone is
the primary method by which athletes are tested positive for
doping with Testosterone[5].
For other anabolic steroids, the detection is even easier, as
metabolites of different unique analogues and derivatives are
very easy to identify once known. For example Deca-Durabolin
(Nandrolone Decanoate) is easily detectible via the detection of
its metabolite 19-norandrosterone in the urine. If the amount of
19-norandrosterone in the urine is found to be much higher than
a particular amount deemed as a normal physiological level, it
can be presumed that the athlete or individual had been using
Nandrolone. Another example, Winstrol (Stanozolol) can be
detected via the presence of 3’hydroxystanozolol in the urine,
which is a metabolite of Winstrol that lingers in the user’s
urine for up to 10 days following use[6]. The use of mass
spectrometer can even detect non-metabolized Nandrolone
molecules in urine due to its unique properties. It is through
the detection of the metabolites of the different anabolic
steroid that essentially determines the steroid detection times
that have been more or less established.
You Need to Know What You Are Looking For!
In general, it should be understood that in order for an
anabolic steroid to be detected in a test, the specific anabolic
steroid, and more specifically its metabolites, must be known
prior to the testing procedure. This is why it has been
mentioned earlier in this article that anabolic steroid testing
involves the testing for all known anabolic steroids and their
analogues. An anabolic steroid that is not known cannot be
found. In order to find something, you need to know what you are
looking for first before any investigation begins. This is the
reason as to why many athletes have circumvented testing
procedures and have successfully doped without being caught (or
have gone a very long time doping before being caught). These
athletes merely utilized designer steroids that were unknown at
the time, or through the use of a newly designed or created
compound. If the athlete utilizes an anabolic steroid that is
not yet known or is yet to be discovered and it is kept a
closely guarded secret, that athlete will get away with it no
matter how much he is tested.
This is evidenced in history during the Olympics, where East
Germany ran a state-sponsored program known as State Plan
Research Theme 14.25, which as a program designed to circumvent
the IOC testing procedures and have all of their Olympic
athletes (both knowingly and unknowingly) utilizing anabolic
steroids in an effort to undetectably gain an advantage over
other competitors[7]. The East German government implemented
this program and ran it for over 20 years, and involved the use
of undetectable (at the time) anabolic steroids, due to their
relatively new development and unknown status.
Steroid detection times can be influenced by many different
factors, mostly involving the different metabolic pathways and
excretion methods. Anabolic steroid detection times can be
influenced by the type of anabolic steroid used, the specific
properties of that anabolic steroid, the dose, the duration of
use, and route of administration (oral or injectable).
Influences and Factors on Steroid Detection Times
Every anabolic steroid exhibits a different characteristic or
property, and some can be quite different from others, while
some are very similar to others. Some previous factors mentioned
included: the type of anabolic steroid used, the specific
properties of that anabolic steroid, the dose, the duration of
use, and route of administration (oral or injectable). Other
further factors include: fat solubility, and resistance to
metabolism. Some anabolic steroid detection times, as a result
of these factors, are extremely long while others are very
short. Steroid detection times can vary quite greatly as a
result and those individuals and/or athletes who are subject to
anabolic steroid testing should always be fully aware of the
different anabolic steroid detection times of the different
compounds. Some anabolic steroids might be more suitable than
others for the purpose of the avoidance of a positive test
result, and others are much less suitable and should be avoided
at all costs. A full list of the different and most common
anabolic steroids and the individual steroid detection times
will be presented at the end of this article.
Type of anabolic steroid used: The type of anabolic steroid used
can have a very influential factor on their individual steroid
detection times. As mentioned previously in this article, it is
perhaps much easier to ‘get away with’ the use of Testosterone
at supraphysiological (bodybuilding) doses rather than the use
of certain other compounds, merely due to the fact that the
metabolites are very similar to those secreted by the body
endogenously. There might also be a greater leeway for
acceptable levels of metabolites in this case, as well as the
faster clearance of them. For example, Testosterone suspension
is an un-esterified variant of Testosterone that can completely
clear the body within 12 – 24 hours, and this can also mean that
the Testosterone:Epitestosterone ratios in the user’s urine can
and will return to normal ranges even faster than the use of a
longer-acting variant of Testosterone, such as Testosterone
Enanthate.
Properties unique to an anabolic steroid: Some anabolic
steroids, such as Nandrolone (Deca-Durabolin) or Winstrol
(Stanozolol), as mentioned previously can metabolize into very
unique and highly identifiable metabolites in the user’s urine.
Deca (Nandrolone) in particular is a very notorious anabolic
steroid for a high rate and chance of detection, as one of the
reasons is due to the fact that Nandrolone’s metabolites in
urine tend to remain for an excessively long period of time in
the body in comparison to many other anabolic steroids. Deca is
perhaps regarded as the worst offender when it comes to steroid
detection times, and is an anabolic steroid that is recommended
for tested athletes to avoid at all costs as a result.
Dose and duration of use: Generally self-explanatory, the dose
and duration of use make a very large impact on anabolic steroid
detection times. Obviously, the higher the dose and/or the
longer the duration of use of any anabolic steroid, the longer
the detection time will be and the easier it will be to detect
the anabolic steroid in bioassays. Higher dosage of an anabolic
steroid means that the human body must process more of the
hormone in and out of the body, and metabolize much more of it.
There is always a limit as to how fast the body can metabolize
hormones (or anything else), leaving the body to be able to
metabolize compounds only so fast. The body has only limited
amounts of enzymes and catalysts to process and metabolize
drugs, chemicals, hormones, and food, and the higher the dosage,
the greater the demands placed upon these biochemical resources
and enzymes to perform metabolism. The result can be a slower
metabolism of the anabolic steroids in and out of the body,
resulting in altered longer steroid detection times than the
hormone would otherwise exhibit. The same goes for duration of
use – longer cycles mean longer steroid detection times.
Route of administration: Oral anabolic steroids are known as
being very fast to reach peak blood plasma levels in the body,
and equally very fast to clear. This is because the route of
administration involves oral ingestion, which exposes the active
hormone immediately to the liver and the bloodstream, resulting
in fast metabolism (especially considering the liver is
essentially where the body’s center of metabolic processes
occurs). On the other hand, injectable anabolic steroids exhibit
a slower release and slower metabolism in the body (for the most
part). While oral anabolic steroids all exhibit half-lives of 4
– 24 hours (depending on the compound used), injectable anabolic
steroids (especially esterified ones) exhibit half-lives of 24
hours to 15 days or more, depending on the compound used. Some
injectable anabolic steroids, such as Testosterone Suspension,
exhibit a very short half-life of approximately 4 – 24 hours. It
stands to reason that most of the time, the shorter the
half-life of an anabolic steroid, the shorter the duration its
metabolites remain in the body.

Fat solubility: Anabolic steroids by nature are lipids (fats),
though they are not the traditional chemical characteristic of a
hydrocarbon chain. They are nevertheless very fat soluble, and
blend well with fats (hence why they are able to seamlessly pass
through the lipid bilayer of cells in order to exert their
activity). Because of the fat solubility, anabolic steroids and
their metabolites can linger in fat tissue for very long periods
of time, and some are very notorious for this, such as Deca
(Nandrolone). Nandrolone is known as being a very fat soluble
hormone that can linger in fat tissue (as well as its
metabolites) for over a year after use. Furthermore, the
esterification that is commonly done to injectable anabolic
steroids even further increases their solubility in fats, which
causes their individual steroid detection times to increase even
further. For example, the detection time of Testosterone
Propionate is not as long as Testosterone Enanthate or
Testosterone Cypionate. The reason for this difference is
because of the esters attached to the Testosterone molecules
that alter their rates of release, and therefore their
metabolism, and ultimately their steroid detection times.
Resistance to metabolism: The more resistant an anabolic steroid
(or any hormone, drug, and even food) is to metabolism in the
body, the longer it (and its metabolites) will remain in the
body. One such compound that is a perfect example of this is
Trenbolone, which is highly resistant to metabolism in the body
and is also excreted in urine un-metabolized in a very high
percentage. Although Trenbolone’s detection time is not as long
as something like Nandrolone, it is still fairly long
(approximately 4 – 5 months).
