Halotestin is the Upjohn brand name for the steroid fluoxymesterone.
Structurally fluoxymesterone is a derivative of testosterone, differing
from our base androgen by three structural alterations (specifically
l7alpha-methyl, 11 beta-hydroxy and 9-fluoro group additions). The result
is a potent oral steroid that exhibits extremely strong androgenic
properties. This has a lot to due with the fact that it is derived from
testosterone, and as such shares important similarities to this hormone.
Most importantly, like testosterone, Halotestin appears to be a good
substrate for the 5-alpha reductase enzyme. This is evidenced by the fact
that a large number of its metabolites are found to be 5-alpha reduced
androgens, which coupled with its outward androgenic nature, suggests it
is converting to a much more active steroid in androgen responsive target
tissues such as the skin, scalp and prostate.
The 11
beta-hydroxyl group also inhibits aromatization, making estrogen
production impossible with this steroid. Estrogenic side effects such as
water retention, fat fain and gynecomastia are therefore not a concern
when taking this compound. Strong androgenic side effects are to be
expected though, and in many cases are unavoidable. Oily skin and acne a
very common for instance, at times requiring sensitive individuals to seek
some form of topical or even prescription drug treatment to keep it under
control. Hair loss is an additional worry, making Halotestin a poor choice
for those with an existing condition. Aggression may also become very
pronounced with this drug. This effect is often desired by users looking
to "harness" this in order to increase the intensity of workouts or a
competition. Clearly Halotestin is a strong androgen, and definitely one
female athletes should stay away from. Masculinizing side effects can be
intense, and may occur very rapidly with this substance. Even women daring
enough to take Dianabol should think twice
about this compound, as virilization symptoms are most often permanent.
Although Halotestin appears to be more androgenic than testosterone, the
anabolic effect of it is not very strong. This makes it a great strength
drug, but not the best for gaining serious muscle mass. The predominant
effect seen when taking Halotestin is a harder, more dense look to the
muscles without a notable size increase. It is therefore very useful for
athletes in weight-restricted sports like wrestling, powerlifting and
boxing. The strength gained from each cycle will not be accompanied by a
great weight increase, allowing most competitors to stay within a
specified weight range. Halotestin also makes an excellent drug for
bodybuilding contest preparation. When the competitor has an acceptably
low body fat percentage, the strong androgen level (in absence of excess
estrogen) can elicit an extremely hard and defined "ripped" look to the
muscles. The shift in androgen/estrogen ratio additionally seems to bring
about a state in which the body may be more inclined to burn off excess
fat and prevent new fat storage. The "hardening" effect of Halotestin
would therefore be somewhat similar to that seen with trenbolone, although
it will be without the same level of mass gain. Clearly non-aromatizing
androgens such as Halotestin and trenbolone
can play an important role during contest preparations.
The
main concern with this steroid is that it can be a very toxic drug. This
is due to the fact that fluoxymesterone is a 17 alpha alkylated compound,
its structure altered to survive oral administration. l7alpha alkylation
can be very harsh to the liver. The possibility of damage is therefore a
legitimate concern with Halotestin, especially when used at higher doses
or for prolonged periods of time. The total daily dosage is likewise best
kept in the range of 20-40mg, used for no longer than 8 weeks. After which
an equally long break (at a minimum) should be taken from all c17-AA
orals. One should also resist the temptation to stack this drug with other
alkylated orals if possible, and instead opt for orals without this
alteration or esterified injectable compounds (which will not add to the
strain on the liver).
In
cutting phases a mild anabolic such as Deca
Durabolin or Equipoise might prove to be a
good addition, as both provide good anabolic effect without excessive
estrogen buildup. Here Halotestin will provide a well needed androgenic
component, helping to promote a more solid and defined gain in muscle mass
than obtained with an anabolic alone. Perhaps
Primobolan Depot would even be a better choice, as with such a
combination there is no buildup of estrogen (and likewise even less worry
of water and fat retention). For mass we could alternately use an
injectable testosterone. A mix of 400-800mg
Testosterone enanthate and 20-30mg Halotestin for example, should
prove to be an exceptional stack for strength and muscle gain. This
however would be accompanied by a more significant level of side effects,
both compounds exhibiting strong androgenic activity in the body.
Fluoxymesterone also seem to depress endogenous testosterone levels rather
quickly with use, despite its complete lack of estrogen conversion. One
therefore should consider ancillary drug use at the conclusion of each
cycle in order to help restore the normal release of androgens in the
body. Using a combination of HCG and
Clomid/Nolvadex is of
course the best option, the two drugs working well together to restore
normal hormonal functioning. Although estrogen is not a problem with
Halotestin, the use of an anti-estrogen such as
Nolvadex
or
Clomid
is still indicated when discontinuing a cycle. Since
HCG
stimulates
aromatase activity in the Leydig's cells, here
Clomid/Nolvadex
help by blocking the activity of any excess estrogen that may be produced.
Afterward they will also block the inhibitory effect of endogenous
estrogens on the hypothalamus, stimulating the enhanced release of
gonadotropins and supporting the normal biosynthesis of testosterone.
Since
Halotestin is only used for a few specific purposes, it is not in high
demand among athletes. Likewise it is not a very popular item on the black
market. Investing in the manufacture of a counterfeit version would
probably not pay off well, no doubt the reason we haven't seen any yet.
All of the various forms of Halotestin could therefore be assumed
legitimate when found in circulation. Overall, Halotestin is an effective
steroid for a narrow range of uses, and is probably not the most ideal
product for the recreational user.
