was created as an attempt to produce
an injectable version of Dianabol
To do this, scientists simply added an ester (the very slow releasing
Undeclynate ester) to the same steran nucleus they created out of testosterone
to create Dianabol. This means they simply added a double
bond between carbon atoms 1 and 2, and in this case, estrified it. This
1-2 double bond dramatically slows the rate of conversion to estrogen.
So what does this mean to us, in the real world? For starters, Eq,
because of that simple modification is only going to convert to estrogen
(aromatize) at about half the rate of Testosterone. 
Although it rates as highly as Testosterone
in terms of anabolic
effects, but itís only half as androgenic. However, in the real world,
not too many users report the kind of weight gain on Eq as they do with
although strength gains seem to be very similar. This is probably why
Eq has a well deserved reputation as a hardening agent, and a good
cutting drug, but not really as a bulking drug. When itís used in a
bulking cycle, itís primarily used to aid in appetite stimulation,
which is a property of this drug that has been experienced by many
athletes- myself included.
The aforementioned double bond is also responsible for Boldenone being
somewhat resistant to the 5-Alpha-reductase enzyme. 
is responsible for converting Testosterone into Dihydrotestosterone
(DHT), and in this case only converts a small amount of Boldenone into
Dihydroboldenone (DHB, I suppose?), which is actually a very potent
androgen in itís own right (7x as anabolic as testosterone)
However, to reiterate, only a small amount of Eq is converted to DHB,
thus making it not much of a itís really of no concern.
For some reason, Eq is usually compared with Deca
, and the only real comparison is that gains with
the two are very similar, with perhaps the edge in strength going to
Eq, and the edge in weight gain going to Deca Durabolin. In terms of
action in the body, Eq doesnít act much like Deca. In fact, Deca is a
progestin and a 19-nor derived steroid whereas Eq is much more closely
related to testosterone (being only one double bond different). Still,
itís very uncommon to see both of them in the same cycle, although
thereís no real reason to avoid using the two together.
Most likely due to itís long ester, most athletes and bodybuilders who
have used Eq typically report something of a slow and constant buildup
of quality muscle, rather than quick, watery gains. Typically, people
use this compound for at least 10 weeks of a cycle, and 12 is often
preferred as the weight and strength gains often come very slowly from
Lately, much shorter estered versions of Boldenone have become
available from several underground labs. Since the ester takes up a
good deal of ďspaceĒ in actual oil, the real advantage to this is that
there will be a more rapid build up of strength and weight, and less of
a waiting period to see results. Boldenone Propionate and Boldenone
without an ester (typically referred to as ďBNEĒ) are both available,
and Iíve experimented with the latter and found it to actually be very
comparable to Masteron in the sense of gaining hardness and strength
without much if any water or weight gain.
Equipoise is usually injected at a dose of between 400 and 600 mgs
every week, but more than that would seem to not produce any additional
benefits according to most experienced users.
Eq, just as with almost any anabolic
steroids, will cause
suppression of your endogenous hormones, such as endogenous LH, FSH,
and testosterone. Typically, as exogenous androgen levels
rise, endogenous (natural) levels fall. This is why Eq is almost never
used alone, and some form of injectable testosterone is the most common
addition to a cycle where Eq is being used.
For the last few decades, steroid users have enjoyed the fact that Eq
is both widely available and relatively inexpensive. Most
underground labs offer their own version of Equipoise for around $50-75
for a 10cc bottle dosed at 200-300mgs/ml.
A very cheap ďstarter cycleĒ of Eq and testosterone is currently very
popular and I would wager that unless something severe happens to
either the price or availability of EQ, itís going to be a cornerstone
of both beginners and advanced users for decades more.
