Testosterone is responsible for the development and maintenance of
male secondary sex characteristics. This includes it being a highly
anabolic and androgenic hormone, therefore being capable of
increasing users' muscle mass and strength/power when administered
at larger than normal doses in the body. The testosterone enanthate
compound itself is an injectable oil which contains testosterone
with the enanthate ester attached to the testosterone molecule.
When the enanthate ester is adding to testosterone base, it creates
a long-acting form of testosterone. This requires a user to only
inject the compound once or twice per week to maintain fairly
stable levels of the compound, something that is obviously an
advantage. Blood levels of testosterone enanthate will fall rather
dramatically five days after it is administered, however the level
of the compound should still be well above baseline after a week.
This is quite similar to the cypionate ester. In fact, testosterone
cypionate and enanthate are basically interchangeable in terms of
active life and half life, including almost identical release
patterns. Enanthate was primarily manufactured in other areas of
the world outside of North America. Cypionate was the ester of
choice for North American companies in the early stages of anabolic
steroid development. However now both of these esters are used
throughout the world having both maintained their popularity with
users. They are both widely available.
Testosterone is able to promote strength increases and muscular
growth via numerous mechanisms. Of course first off testosterone
promotes nitrogen retention in muscle therefore allowing the
muscles to hold more protein and enabling repair and growth of
those muscles. Secondly testosterone binds to the androgen receptor
to promote receptor dependant mechanisms for muscular growth and
fat loss. Testosterone also helps to increase the concentrations of
androgen receptors in cells that are important for muscle growth
and repair in muscle1 .
As mentioned, testosterone can play a role in promoting fat loss.
Testosterone has the ability to bind to the androgen receptors in
fat cells. This can enable the breakdown of body fat while and also
deters new fat formation2 . Of course due to the fact that testosterone will encourage
muscular growth, indirectly it will promote fat reduction because
any excess calories are likely to be used in the muscle building
process rather than being added as body fat.
Like most anabolic steroids, testosterone also increases red blood
cell production. An increased number of red blood cells in the
blood can improve endurance via better oxygenated blood as well as
improving a user's ability to recuperate after strenuous physical
activity. However it should be noted that there are other steroids
and compounds out there that are far more adept at this function.
Among the other mechanisms that testosterone can help promote
anabolism are via the increased production of insulin growth factor
1 it encourages, as well as suppressing the action of catabolic
hormones in the body. In terms of performance enhancement,
testosterone also offers numerous advantages. Namely it has the
ability to increase the number of motor neurons in muscles and
thereby improving muscular contraction. Like many other anabolic
steroids testosterone also promotes glycogen synthesis. This will
of course help to improve a user's endurance and strength by
providing more fuel for intense workouts thus increasing endurance
and strength, as glycogen is stored carbohydrates used as a fuel
during exercise3 .
Some users believe that testosterone enanthate should be reserved
for "bulking" cycles and is not appropriate for those cycles in
which a user is hoping to reduce body fat. However this is a
misnomer as the ester of the compound can not alter it's
physiological effects. Depending on the diet and training routine
of the user, testosterone enanthate can be used quite effectively
for either mass building or cutting cycles. This belief that
enanthate should only be used for bulking cycles may originate from
the fact that a majority of users anecdotally report that they
experience more water retention/bloat while using testosterone
enanthate in comparison to other shorter acting testosterone
esters. This water retention and bloat would seemingly make the
user appear "puffy" and therefore may lead the individual to
believe that they are indeed increasing their body fat, while the
lack of water retention that they experience with the shorter
acting esters may make them think that they are reducing their body
fat when that may not be the case.
However, a minority of users also report that they hold less water
while using testosterone enanthate than testosterone propionate.
This again demonstrates that individuals react quite differently to
various compounds. Experimentation with the various compounds is
the only sure way to see how you react.
The ester enanthate is seven carbons in length. Due to this length
the majority of the compound is stored in the adipose tissue when
injected intramuscularly. In doing so it is steadily released over
a period of time. A peak in the blood level of the compound is
reached after 24-48 hours after the injection followed by a slow
decline. This requires that a user wait about fourteen days after
the last injection to begin their post-cycle therapy to ensure that
the compound has completely cleared the system of the user.
In terms of an actual injection schedule most users will inject
testosterone enanthate twice per week. However, some users will
administer the compound only once per week or may choose to inject
several times per week. The more frequently a user injects the more
stable the blood levels of the compound will be, assuming of course
that the doses are equally distributed and of the same amount.
As with the other testosterone esters, the doses of the drug that
are taken by users varies to a great degree depending on the
experience and goals of the user. Doses as low as 200-250mgs per
week have been reported by users who say they have made good gains,
with experienced users administering several grams of testosterone
per week. The range of use is very wide. This also includes women
administering testosterone. It is because of the long active life
of the enanthate ester, it is not recommended that women who choose
to administer testosterone use it or other long-estered formulas.
This is due to the fact that slow acting esters can not be quickly
altered if negative side effects become overly burdensome. By
having to deal with the slow release of the testosterone and not
being able to lower doses or cease administration of the compound
immediately, it makes it much more likely that any side effects
that are experienced will be more pronounced and/or exaggerated.
For this reason, females who use testosterone may want to begin
with testosterone propionate or suspension when choosing which
ester to use and not enanthate.
Most of the side effects that result from using testosterone in
males is related to testosterone's high tendency to convert into
estrogen via the aromatase enzyme. These side effects can include
water retention and gynecomastia. Users often complain that water
retention is much more severe with longer acting esters than with
shorter acting esters such as propionate. To combat these side
effects users can use aromatase inhibitors and/or selective
estrogen receptor modulators. Of course the likelihood of estrogen
related side effects increase as the dosages are raised. However
these should be controllable if the proper precautions taken.
Of course being testosterone, user's should also expect to deal
with androgenic side effects as a possibility. These side effects
can include facial/body hair growth, exacerbation of male pattern
baldness, and oily skin/acne, among others. Some users may wish to
use products such as Proscar/Propecia to reduce the amount of
testosterone that converts to dihydrotestosterone. Finasteride is
also an option that users' can pursue.
Due to the suppression of natural testosterone levels, testicular
atrophy is also likely to occur in some individuals. Use of human
chorionic gonadotropin can help to prevent this, among it's other
effects. Of course a proper post-cycle therapy should be run once
administration of the compound is completed to help recover fully
functioning natural testosterone production.
Women may find that other shorter acting esters are more manageable
than longer acting such as testosterone enanthate. This is due to
the fact that the fast acting esters can be controlled easier and
that the dosing and administration of the compound can be quickly
altered if negative side effects become overly burdensome. With
longer acting esters these adjustments are much more difficult to
make rapidly and side effects could become more pronounced and/or
exaggerated. For this reason, females who use testosterone may want
to at least begin with shorter acting esters if they experiment
Of course with women using testosterone there is a possiblity that
virilizing symptoms could occur. Deepening of the voice,
body/facial hair growth, and enlargement of the clitoris are all
possible side effects of testosterone use. These are for the most
part irreversible4 .
