Drostanolone Propionate is an anabolic androgenic steroid that
first hit the market around 1970 under the trade name Masteron
manufactured by Syntex. However, the compound was actually
developed by Syntex in 1959 along with Oxymetholone (Anadrol) but
would not be released until well after Anadrol. Syntex would also
provide the compound under numerous other brand names such as
Masteril and Metormon among others, as well as Drolban under the
license given by Syntext to Lilly. However, Masteron has remained
the most recognizable brand.
Test 600x As a therapeutic agent, Masteron enjoyed two decades of
success in combating advanced inoperable breast cancer in
postmenopausal women. It would also become a popular cutting
steroid among bodybuilders, which is where Masteron is currently
most commonly found. However, the original Masteron brand is no
longer available; in fact, nearly every pharmaceutical brand on
earth has been discontinued. This compound is still approved by the
U.S. FDA, but it is rarely used in breast cancer treatment any
longer in favor of other options. The steroid is, however, still
tremendously popular in competitive bodybuilding cycles and often
considered essential to contest preparation.
Masteron Functions & Traits:
Drostanolone Propionate is a dihydrotestosterone (DHT) derived
anabolic steroid. Specifically, Masteron is the DHT hormone that
has been structurally altered by the addition of a methyl group at
the carbon 2 position, This protects the hormone from the metabolic
breakdown by the 3-hydroxysteroid dehydrogenase enzyme, which is
found in the skeletal muscle. It also greatly increases the
hormone’s anabolic nature. This simple structural change is all it
takes to create Drostanolone, and from here the small/short
Propionate ester is attached in order to control the hormone’s
release time. Drostanolone Enanthate can also be found through some
underground labs, which does not have to be injected as frequently,
but it is somewhat rare compared to the Propionate version. The
majority of all Masteron on the market will be Drostanolone
On a functional basis, Masteron is well-known for being one of the
only anabolic steroids with strong anti-estrogenic properties. Not
only does this steroid carry no estrogenic activity, but it can
actually act as an anti-estrogen in the body. This is why it has
been effective in the treatment of breast cancer. In fact, the
combination of Masteron and Nolvadex (Tamoxifen Citrate) has been
shown to be far more effective than chemotherapy in the treatment
of inoperable breast cancer in postmenopausal women. This also
makes it a popular steroid among bodybuilders as it could actually
prohibit the need for an anti-estrogen when used in the right
cycle. This will also prove advantageous during the cutting phase
due to the hardening effects it can provide.
Masteron carries relatively low anabolic and androgenic ratings;
however, these ratings are somewhat misleading. It’s important to
remember DHT, the basis of Masteron, is five times more androgenic
than testosterone with a much stronger binding affinity to the
androgen receptor. This again promotes a harder look and can also
enhance fat loss. Most all anabolic steroids are well-noted for
enhancing the metabolic rate, but strong androgens have a tendency
to directly promote lipolysis.
As an anabolic, Masteron isn’t well-known for promoting gains in
lean muscle mass. It has never been used for muscle wasting in a
therapeutic sense and will almost always be found in cutting plans
among performance athletes. It can, however, promote significant
boosts in strength, which could prove beneficial to an athlete who
may not necessarily be looking for raw mass.
Effects of Masteron:
Without question, the effects of Masteron will be displayed in the
most efficient way during a cutting cycle. However, for the effects
to be truly appreciated the individual will need to be extremely
lean. This is why the hormone will most commonly be found at the
end of bodybuilding contest prep cycles as the individual should
already be fairly lean at this stage. The added Masteron will help
him lose that last bit of fat that often hangs on for dear life at
the end of a cycle. It will also ensure his physique appears as
hard as can be. Of course, the anti-estrogenic effect will simply
enhance this overall look. For those that are not competitive
bodybuilder lean, it is possible that the effects of Masteron may
not be all that noticeable. The individual who is under 10% body
fat should be able to notice some results and produce a harder,
dryer look, but much over 10% and the effects may not be all that
As a potent androgen, Masteron can benefit the athlete looking for
a boost in strength. This can be a very beneficial steroid for an
athlete who is following a calorie restricted diet in an effort to
maintain a specific bodyweight necessary for his pursuit. The
individual could easily enjoy moderate increases in strength and a
slight improvement in recovery and muscular endurance without
unwanted body weight gain.
