Nandrolone is by far one of the most popular anabolic steroids
available. This is due to the compound's affinity for being highly
anabolic but relatively mild in terms of androgenic side effects.
Nandrolone is the base steroid 19 Nor-testosterone, meaning that it
is like testosterone in appearance except for the absence of a
carbon atom in the 19th position. This small change makes a major
difference in the characteristics of the compound1. Notably, this
change makes nandrolone a less potent agonist of the androgen
receptor. This of course reduces the chance that a user will
experience androgenic side effects. Instead of forming
dihydrotestosterone when encountering the 5 alpha reductase enzyme
like testosterone does, nandrolone will form dihydronandrolone.
Dihydronandrolone is extremely mild in terms of it's antagonizing
the androgen receptor. Therefore androgenic side effects should be
far less likely to occur with nandrolone than with testosterone.
It is of note however that nandrolone is believed to have some
activity as a progestin in the body. Although progesterone is a
c-19 steroid, removal of this group as in 19-norprogesterone
creates a hormone with greater binding affinity for its
corresponding receptor. The compound will stimulate the
progesterone receptor, along with progesterone. Side effects
associated with this activity are similar to some of those related
to estrogenic ones including water retention, acne, and
gynecomastia among others. However these side effects are fairly
rare in comparison to more androgenic compounds.
Now, with the reduced chance of negative side effects associated
with the use of nandrolone one would assume that the gains in lean
body mass that a user could expect to make would also be reduced.
This is not true however. Nandrolone is 2.4 times as anabolic as
testosterone when compared gram for gram1. This does not mean that
a user will gain 2.4 times as much muscle if using nandrolone
instead of testosterone however. It is not that easy. It does show
how powerful this drug is and how it can help a user make serious
gains in muscle mass.
Due to the active life of the compound, users would only need to
administer nandrolone decanoate once per week to maintain fairly
stable of the drug. However, since the vast majority of users will
stack nandrolone with testosterone (for reasons that will be
discussed later in the Side Effects/Risks section of this profile)
and the most commonly used esters need to be injected more
frequently most will simply injected it when it is convenient, such
as twice a week with their testosterone enanthate or cypionate.
Anecdotally most users report that the full benefits of nandrolone
decanoate will not be felt until the fifth, sixth or even seventh
week of using the compound. This necessitates that users run the
drug for at least eleven or twelve weeks for a cycle of the
compound to have the results that a user expects. Of course, since
nandrolone decanoate is a relatively mild drug many users have run
it for extremely lengthy cycles with little in the way of serious
Most inexperienced male users will start using about 400mgs of
nandrolone decanoate during their first cycles of the compound.
Like most drugs users have used quite large doses of the compound,
with diminishing returns being seen as these doses go higher and
Females also have found that nandrolone can be quite effective
while offering relatively mild side effects. Doses ranging from
about 50 to 150mgs per week seem to be the norm for most first time
users of the compound, again with these doses increasing as users
try to achieve more and more with the compound.
Estrogenic effects are not a major concern with use of nandrolone
due to it's low rate of aromatization. However it can cause
progesterone-like effects in some users. Commonly reported sides
effects associated with nandrolone are such things as acne/oily
skin, insomnia, diarrhea, and nausea. These of course are coupled
with the common side effects most often associated with anabolic
steroids including testicular atrophy, gynecomastia (including
lactation in some cases), and sexual dysfunction.
To combat sexual dysfunction most users will stack testosterone
with nandrolone. The obvious choice to be used with nandrolone
decanoate is testosterone enanthate or cypionate due to the length
of the esters being similar. How much testosterone one would need
to take to ward off side effect associated with use of nandrolone
and lack of natural testosterone production varies from individual
to individual. Some have anecdotally reported that a low dose
similar to 200mgs per week is enough. Others state that they need
to run several hundreds more milligrams per week of testosterone
than nandrolone to combat the effects. There is a small minority of
individuals that also report having no sexual dysfunction from the
drug even while running it without any type of testosterone. This
variance again demonstrates that individuals will react to a
compound differently than others.
This effect also points to the fact that nandrolone is extremely
suppressive to a user's natural testosterone production. Even at
relatively small doses, much smaller than those that would be used
by those wanting to reap the anabolic effects that the compound can
offer, nandrolone can suppress the natural production of
testosterone of a user so much that it can take up to thirty days
after the drug cycle is complete for it to fully recover2 . For
this reason it is imperative that a user run a well planned post
cycle therapy after using nandrolone.
Nandrolone is relatively safe in terms of a user's lipid profile
and cholesterol. In some studies it has even been shown to actually
improve HDL cholesterol levels4 . A major increase in a user's
blood pressure or their liver toxicity should not be noticed with
this compound either. Nandrolone is relatively mild in these
Since nandrolone is a progestinic anabolic steroid3,4 . Some
special precautions need to be taken to ensure that side effects do
not get out of control as a result of a rise in prolactin levels.
Using compounds such as bromocriptine, cabergoline and/or vitamin
b6 have all been shown and reported to help lower prolactin levels.
The drug Femara (letrozole) is also effective for use with
nandrolone as it will regulate the progesterone and estrogen
receptors in the body, therefore preventing some of the negative
side effects associated with the compound.
A word of caution also for those that may plan on stacking
nandrolone with trenbolone. Trenbolone is a strong progestin, much
stronger than even nandrolone. By running these two compounds
concurrently the user will suffer from extremely high levels of
prolactin. This in turn will force the user to pay special
attention to progesterone-like side effects and using compounds to
prevent them, as well as having to run a particularly aggressive
post-cycle therapy due to severe suppression of the hypothalamus
pituitary testicular axis. Some users have anecdotally reported
that they have suffered no ill effects of running the two compounds
together, but it is a definite risk. One must weigh the costs
versus the benefits.
