Masteron is an injectable preparation containing the steroid
drostanolone propionate. Drostanolone is a derivative of
dihydrotestosterone, most specifically
As a result, the structure of this steroid is that of a moderate
anabolic/potent androgen which does not aromatize to estrogen.
Water retention and gynecomastia therefore do not come into play
with this drug. Masteron may in fact exhibit anti-estrogenic
activity in the body, competing with other substrates for binding
to aromatase. This would reduce the conversion rate of other
steroids, Masteron acting in the same way as the oral steroid
Bodybuilders have a strong like for non-aromatizing androgens, and
find Masteron very useful in a cutting phase. It is generally used
for a number of weeks prior to a competition, in an effort to bring
out an improved look of density and hardness to the muscles. As
long as body fat percentage is low enough, Masteron should work
Provided everything fits as if should, the user can achieve that
"ripped" look so popular to professional bodybuilding. The
androgenic effect can also be crucial during this period, a time
when caloric intake is drastically lowered. The user is provided
added "kick" or "drive" to push through the grueling training
sessions leading up to the show.
Since the propionate ester is used with this compound, injections
need to be repeated at least every 3 or 4 days in order to maintain
a consistent level of hormone in the blood. The weekly dosage is in
the range of 300-500mg.
Since estrogen is not an issue, side effects are generally mild
with this steroid. As discussed earlier, gynecomastia, water
retention, and high blood pressureare not a problem. Masteron is
also not liver toxic, so there is little concern stress will be
placed on this organ, even during longer cycles.
The only real side effects would be from the basic androgenic
properties of dihydrotestosterone. These includes oily skin, acne,
body/facial hair growth, aggression and accelerated hair loss.
Since this compound is already a synthetic DHT, Proscar would have
no impact on the level of androgenic effects. Men with a receding
hairline or those with a predisposition for baldness may therefore
wish to stay away from Masteron completely, as the potent
androgenic effect of this steroid can easily accelerate this
