Dihydroboldenone, most commonly known as 1-testosterone, is a 5alpha reduced
form of the steroid boldenone. This lack of 5alpha reduction with the compound
allows users to administer it without suffering the negative side effects
associated with this chemical reaction but also eliminates the benefits as
well. Boldenone is not the only steroid that shares similarities with
dihydroboldenone. In fact dihydroboldenone is chemically identical to the drug
methenolone except for the 1-methylation that is apart of methenolone (1).
1-methylation was of course added to methenolone to make it more available
when taken orally and thus dihydroboldenone is not efficiently utilized when
administered orally, although it was once sold over the counter in tablet and
pill form. Some of these over the counter preparations of the drug were done
utilizing a delivery system similar to Andriol, i.e. producing an oil-solubilized
product with dihydroboldenone. This would still not be a relatively worthwhile
system of delivery to use however if one wanted to maximize the potential of
the compound. Intramuscular injection is by far the most efficient method of
administration to use as with most anabolic steroids.
As mentioned above, dihydroboldenone is structurally similar to methenolone
and boldenone and less so to testosterone despite the commonly used name for
it, 1-testosterone. For this reason some female athletes may be inclined to
use the drug as well. The potential for development of symptoms of
virilization still remain but are not as severe as with synthetic testosterone
or other harsher drugs. This is not to say however that dihydroboldenone is a
mild drug. To simplify the explanation of exactly what the drug is, it is to
boldenone as dihydrotestosterone (DHT) is to testosterone. This would explain
why the effects of the drug, both positive and negative, are so dissimilar to
those of boldenone. Like testosterone and dihydrotestosterone, a portion of
the boldenone that a user administers converts to dihydroboldenone. Also
similarly, dihydroboldenone like dihydrotestosterone does not convert to
anything else past that compound.
Dihydroboldenone, while not overly androgenic, is a potent anabolic. It has
been demonstrated that the drug binds extremely well and selectively to the
androgen receptor and stimulates androgen receptor transactivation of
dependent reporter genes (2, 3). This equates to a drug that possesses the
ability to stimulate significant muscle growth while not producing androgenic
side effects. It has been shown to be by far more anabolic then such compounds
as boldenone, nandrolone, and even testosterone itself. Obviously this is of
great benefit to many athletes.
Anecdotally some users have indicated that post-injection pain with
dihydroboldenone can become an issue for some. Diluting the drug with either
another injectable drug or some other type of sterile oil seems to alleviate
at least some of this discomfort. The type of ester used does not appear to
negate this pain for the users that experience it however.
Indeed dihydroboldenone is available in numerous different esters. Cypionate,
Ethyl Carbonate, Propyl Carbonate, and Propionate, among others, are all
available for use with the drug. As always each does not offer any real
advantages over one another other then the obvious differing active lives that
each presents and the amount of time that it takes for the body to completely
eliminate the drug from it (4). For the most part users will want to have
their choice dictated by the injection frequency with which they want to deal
with when using the compound, but of course they will also likely be limited
by those that are made available to them.
As for the duration with which dihydroboldenone can be run, due to the mild
nature of the drug extended use of the compound can be completed with little
in the way of serious complications arising. There are no major issues with
hepatoxicity or severe kidney stress and the effect it has on other vital
health markers such as blood pressure is slight in the majority of users.
As for specific dosages used with this drug, the low end is primarily thought
to be three hundred to four hundred milligrams per week for male users. Like
all drugs this number will vary from user to user and also depends on how much
of a dramatic effect a user will want to achieve with the drug. As for the
highest doses that would be worthwhile for users to attempt, this again
depends on a number of variables. Doses of one gram per week are not uncommon
for some users with others attempting doses in excess of this. It will always
come back to how much one is willing to administer and at what point do the
positives of increasing your doses begin to be outweighed by the negatives.
For females the usual rules apply with dihydroboldenone as they do with other
drugs. These are namely starting out with short esters if possible so that if
side effects begin to become too severe discontinuation of the drug can begin
immediately and low doses should be administered at the beginning of the cycle
and can be increased once the tolerance of the user is gauged. Anywhere from
twenty five to one hundred milligrams per week would be a good starting point
for the majority of female users who have little to moderate experience with
As stated earlier, for the frequency of dosing with dihydroboldenone it of
course depends on the ester used with the compound. Seemingly the most popular
current ester to produce the drug with is cypionate. No matter what ester
utilized however the same rules would apply as with any other drug in terms of
the frequency of administration needed to maintain relatively stable blood
levels of the compound.
As previously indicated dihydroboldenone does not aromatize and therefore
estrogenic side effects such as gynecomastia and water retention are not a
concern for users. This is partly due to the drug being incapable of 5alpha
reduction. Also, androgenic side effects would also be extremely infrequent
for most users as there is little in the way, in terms of attributes of the
drug, to produce these. These include such things as acne and hair loss,
although it appears to have the potential to cause prostate enlargement. This
potential for prostate growth is actually similar in frequency and severity as
with that of testosterone propionate (2).
With the positive aspects of the lack of aromatization associated with
dihydroboldenone also come the negative ones. Fortunately these are primarily
limited to such symptoms as lethargy, malaise and possibly a reduction in sex
drive. These are caused by a lower ratio of estrogen in comparison to
androgens in the body. For the most part however this effect is relatively
slight and can be avoided with the use of steroids that do aromatize in
conjunction with dihydroboldenone and thus restore a better balance in terms
of androgens versus estrogen.
It also appears that the administration of dihydroboldenone may result in an
increase in liver weight (2). This effect occurred when administering the drug
orally but should also be true of the drug when administered via intramuscular
injection. There is no research to indicate this however.
Other common negative side effects associated with the use of
anabolic/androgenic steroids are still relatively mild with the use of
dihydroboldenone. Of course suppression of the natural testosterone production
of users will occur like with all steroids, however other side effects such as
an increase in blood pressure, acne and others are comparably mild and often
times non-existent in users, at least as they are directly related to the
administration of this drug.
In terms of side effects for women, at moderate to heavy doses symptoms of
virilization are likely. These can include such symptoms as clitoral
enlargement, body hair growth and deepening of the voice. At lower doses
however these side effects should not be a concern for the majority of
potential female users.
