Enanthate is a drug that Iím proud to say I actually was able
to use before it was ever sold on the black market. I was made aware of
by the first underground lab who produced it, and they gave me a batch
(dosed at 200mg/ml) before it went to market. I think this
is a really interesting version of the drug, because the concentration
and ester length allow one to get blood levels of the compound to a
much higher level than we would see with traditional Masteron
(which has the propionate ester attached). Studies by Minto et al
suggest the efficacy of more highly concentrated steroids, with regards
to peak plasma levels.
is derived from
Dihydrotestosterone (DHT) but with an added 2a-methyl group.
It is therefore structurally incapable of conversion to either estrogen
or progesterone. Judging
from the literature Iíve seen, the 2a-methyl group would also seem to
make it less of a substrate for 3a-HSD (3alpha-Hydroxysteroid
dehydrogenase), and maybe the beta version of that enzyme as well.
This is good because those enzymes serve to, in some ways, inactivate
DHT. They are responsible for the inactivation of DHT into a
less-anabolic hormone. They are also the reason why injectable DHT is
not produced as an anabolic on its own.

rarely spoken about
property of Masteron is that it is actually a weak (though useful)
anti-estrogen, and thatís where a lot of its ďhardeningĒ
properties probably come from, and why itís so useful in precontest

estrogen. Additionally, Masteron seems to be able to interact with
estrogen at the receptor site. 
I think this explains itís
ďhardeningĒ properties, because with less estrogen in your body, youíll
be holding less water and therefore appear harder. This is also why
people say it ďonly worksĒ at a low bodyfat percentage. When you take
the water retention off of a fat person, you still have a (dryer) fat
person. And if you arenít using a lot of different aromatizable drugs
(and are using them in low doses), or drugs that potentiate estrogenís
effects (and Iím thinking about the 19-nor family here) then Masteron
is likely to be the only anti-estrogen you need. Masteron Enanthate is
effective for this purpose because it has a very long active life and
relatively constant blood plasma levels.
typically stacks well with (*the newly popular) long estered cutting
cycles, which typically include testosterone, and Trenbolone Enanthate.
and typically I like to stack it with something with a similar ester
The minimum dose
with Masteron Enanthate is typically 400mgs/week, although Iíve heard
of it being used EOD (Every Other Day).
If Masteron Enanthate canbe said to have a weakness, it would only be
the price, as it can be relatively expensive.
