Quinbolone is an oral anabolic steroid utilizing the compound boldenone.
Essentially it is to Equipoise what testosterone undecanoate/Andriol is to
testosterone enanthate. The drug is an attempt to make an oral steroid that is
not hepatoxic and therefore can be run for long periods of time without liver
toxicity becoming an issue and without the inconvenience of frequent
injections. The downside to such a drug is that the oral administration of the
drug makes for erratic absorption rates while necessitating larger then normal
Quinbolone is boldenone with the cyclopentenyl ester attached. This ester
helps facilitate fat solubility and absorption while also protecting it from
metabolism before it can become active in the system of the user. Quinbolone
has eliminated the need to alter the compound via 17alpha alkylation so that
it can survive the first pass through the liver and remain effective by
skipping this step all together. This is accomplished by having the structure
of the compound able to be absorbed through the small intestine and lymphatic
system (1). This is possible due to the high fat solubility that the
cyclopentenyl ester provides, as well as the fact that the boldenone is
combined with oil. By bypassing the liver on the first pass, this negates the
need for altering the compound in anyway to ensure that it remains active and
therefore no additional stress is placed on the liver.
The amount of the drug that enters a user's blood stream is dependent upon the
ability of that user's lymphatic system to absorb the compound. This can vary
quite dramatically from user to user. For this reason it is hard to tell
exactly how much of the compound is entering the system of an individual
without taking blood samples at specific times to test for this. For most
users, it will be a guessing game as to how much boldenone cyclopentenyl is
actually being absorbed and active. This is one of the reasons why it is not
considered a complete replacement for injectable compounds.
Despite the obvious problems posed by the unreliable delivery method utilized
by the compound, once the drug is fully absorbed it acts in the exact same
manner as that of other boldenone compounds and brings with it all of the
benefits of the compound (2). Whether or not this is worth the erratic
absorption rates and large doses that are necessary is up to the user him or
Use/Dosing of Anabolicum Vister
Due to the active life of quinbolone users should split their doses of the
drug at least to two or three times per day. This should provide for enough of
the compound to remain active in the system of the user for the majority of
the day. More frequent dosing however would provide even more stable levels of
In terms of the cycle duration, quinbolone can be run for long periods of time
due to the lack of negative side effects associated with the drug as well as
the fact that hepatoxicity is not a concern because it is not a 17alpha
alkylated drug. Users could run quinbolone for several months consecutively
with little ill-effects. The only limiting factor would seemingly be the
financial burden that such an undertaking would provide.
As for the specific dosing required to see results, the average male user will
likely need 100 to 140 milligrams per day to achieve worthwhile results. This
is keeping in mind that dramatic gains in muscle mass and/or strength will be
unlikely for users to experience with this drug, even at massive daily doses.
For female users doses ranging anywhere from 30 to 60 milligrams per day
should be effective for most with little worry needed about negative side
effects at those dosages.
Risks/Side Effects of using Anabolicum Vister
Much like the injectable versions of the drug boldenone, quinbolone is usually
well tolerated by both male and female users. Estrogenic side effects should
not be a concern for the vast majority of male users as only very few will
experience things such as water retention or the possibility of gynecomastia.
The low rate of aromatization should not make the use of ancillary drugs
necessary from quinbolone alone.
Since quinbolone is not 17alpha alkylated and is instead an oil dissolved,
encapsulated oral steroid there is little to no risk of hepatoxicity related
to the use of the drug (3, 4). For this reason users are not at any greater
risk when using the drug for long durations of time, at least in terms of
Similar to estrogenic side effects, androgenic side effects should also be
close to non-existent for nearly all male users. Female users also have little
to fear from this drug in terms of symptoms of virilization such as clitoral
enlargement, deepening of the voice, body hair growth, etc. For the most part
quinbolone is one of the mildest and least likely anabolic steroids to cause
negative side effects in users.
Quinbolone is so mild and void of negative side effects in fact that it was at
one time, while it was still commercially available in Italy which was the
only country to actually produce the drug, prescribed to the elderly to help
address some ailments related to the aging process (2). This speaks to exactly
how few negative side effects and complications are associated with the
administration of quinbolone.
