Masteron is used by people interested in adding muscle hardness and density to their physiques,
nearly always for the purpose of bodybuilding competitions. The drug is
considered to be ideal for this for numerous reasons.
Masteron, being 5-alpha reduced, cannot form estrogen upon interaction
with the aromatase enzyme yet still shows a very high affinity for it. Because
it takes up so much of the aromatase enzyme, yet is refrained from actually
using it by its structural make-up, it reduces the amount of estrogen formed
from other steroids as well because there are less aromatase enzymes to be
used by those compounds to form estrogen with (1). However most will find that
drostanolone is too expensive to employ it for that reason alone, especially
when compounds such as Proviron are available for the same purpose at much
Masteron can increase muscle hardness and density, giving an individual a
more complete appearance when competing on stage. This is an effect that a lot
of pure androgens will exhibit. But with all of them you need an already
rather low body-fat level for it to take full effect. If this is done,
drostanolone can promote increased strength while keeping body fat the same or
even lowering it, something can help to prevent muscle loss while dieting.
This can also allow strength athletes or those athletes in sports which have
weight classes to increase performance without the risk of being raised into a
higher weight class or add mass that may hinder performance.
Masteron is primarily considered a pre-contest drug for bodybuilders. For
it's effects to be fully realized a user must be at a very low body fat
percentage. If a user is not, the muscle "hardening" effect that many look for
when using the compound will not be realized. This, along with the fact that
mass gains are unlikely to be had from the drostanolone, should be a caution
to individuals that they may be disappointed with their results unless they
are well conditioned.
As noted previously, it has been suggested that strength athletes or
competitive athletes could benefit from drostanolone as it can improve
strength while not adding much mass or weight to the user. However, there are
countless other compounds more effective and better suited for such purposes
that the use of Masteron would seemingly be unnecessary for such
Since the propionate ester is nearly always used with Masteron it is
necessary for users to administer the compound everyday or at least every
other day to maintain a fairly stable blood level of the drug. The majority of
users will do well on the compound using doses ranging from 50-100 mg every
day or every other day, totaling 300-500 milligrams per week. More experienced
users of the drug may run higher doses, but since the compound should be
stacked with others to maximize effectiveness, large doses are for the most
part not required.
Aromatization is not an issue with Masteron, as discussed previously.
Therefore, water retention and gynecomastia are not a concern with this
compound, and as stated it in fact exhibits anti-estrogenic capabilities by
way of being able to compete with other substrates while attempting to bind to
aromatase(2). As well, it shows very little in the way of being hepatoxic and
can be run for lengthy cycles without liver damage likely to occur.
In terms of negative side effects, the only real concern would be from the
androgenic properties of dihydrotestosterone. Things such as oily skin, acne,
body/facial hair growth, and hair loss if prone to male pattern baldness.
Masteron is a synthetic form of DHT, therefore Proscar would have no
impact on the level of androgenic effects (1,3). Individuals with a receding
hairline and/or those that are predisposed to male pattern baldness may find
it necessary to avoid this compound as it is likely that it will simply
aggravate the condition further. As should be expected as well, users often
anecdotally reported that the compound can exasperate any existing medical
conditions concerning the prostate, or cause prostate complications in those
that have suffered none before (3).
There are anecdotal reports that some women have experimented with the
compound. However, due to the virilizing effects that will undoubtedly occur
with a compound such as Masteron it is not recommended that this be
attempted. The usual irreversible side effects such as body hair growth,
deepening of the voice and other such symptoms are likely to appear rather
rapidly if use of the drug continued on even a short basis by females.
