PROVIRON-25
Product Description:
PROVIRON-25 is an orally active, 1-methylated DHT. Like Masteron,
but then actually delivered in an oral fashion. DHT is the conversion
product of testosterone at the 5-alpha-reductase enzyme, the result
being a hormone that is 3 to 4 times as androgenic and is structurally
incapable of forming estrogen. One would imagine then that
mesterolone would be a perfect drug to enhance strength and add
small but completely lean gains to the frame. Unfortunately there is a
control mechanism for DHT in the human body. When levels get too
high, the 3alpha hydroxysteroid dehydrogenase enzyme converts it to
a mostly inactive compound known as 3-alpha
(5-alpha-androstan-3alpha,17beta-diol), a prohormone if you will. It
can equally convert back to DHT by way of the same enzyme when low
levels of DHT are detected. But it means that unless one uses
ridiculously high amounts, most of what is administered is quite
useless at the height of the androgen receptor in muscle tissue and
thus mesterolone is not particularly suited, if at all, to promote muscle
hypertrophy.
PROVIRON-25 has four distinct uses in the world of bodybuilding. The
first being the result of its structure. It is 5-alpha reduced and not
capable of forming estrogen, yet it nonetheless has a much higher
affinity for the aromatase enzyme (which converts testosterone to
estrogen) than testosterone does. That means in administering it with
testosterone or another aromatizable compound, it prevents estrogen
build-up because it binds to the aromatase enzyme very strongly,
thereby preventing these steroids from interacting with it and forming
estrogen. So Mesterolone use has the extreme benefit of reducing
estrogenic side-effects and water retention noted with other steroids,
and as such still help to provide mostly lean gains. Its also been
suggested that it may actually downgrade the actual estrogen receptor
making it doubly effective at reducing circulating estrogen levels.
The second use is in enhancing the potency of testosterone.
Testosterone in the body at normal physiological levels is mostly
inactive. As much as 97 or 98 percent of testosterone in that amount
is bound to sex hormone binding globulin (SHBG) and albumin, two
proteins. In such a form testosterone is mostly inactive. But as with the
aromatase enzyme, DHT has a higher affinity for these proteins than
testosterone does, so when administered simultaneously the
mesterolone will attach to the SHBG and albumin, leaving larger
amounts of free testosterone to mediate anabolic activities such as
protein synthesis. Another way in which it helps to increase gains. Its
also another part of the equation that makes it ineffective on its own,
as binding to these proteins too, would render it a non-issue at the
androgen receptor.
Thirdly, mesterolone is added in pre-contest phases to increase a
distinct hardness and muscle density. Probably due to its reduction in
circulating estrogen, perhaps due to the downregulating of the
estrogen receptor in muscle tissue, it decreases the total water
build-up of the body giving its user a much leaner look, and a visual
effect of possessing "harder" muscles with more cuts and striations.
Proviron is often used as a last-minute secret by a lot of bodybuilders
and both actors and models have used it time and again to deliver top
shape day in day out, when needed. Like the other methylated DHT
compound, drostanolone, mesterolone is particularly potent in
achieving this feat.
Lastly PROVIRON-25 is used during a cycle of certain hormones such
as nandrolone, with a distinct lack of androgenic nature, or perhaps
5-alpha reduced hormones that don't have the same affinities as DHT
does. Such compounds, thinking of trenbolone, nandrolone and such
in particular, have been known to decrease libido. Limiting the athlete
to perform sexually being the logical result. DHT plays a key role in
this process and is therefore administered in conjunction with such
steroids to ease or relieve this annoying side-effect. Proviron is also
commonly prescribed by doctors to people with low levels of
testosterone, or patients with chronic impotence. Its not perceived as a
powerful anabolic, but it gets the job done equally well if not better
than other anabolic steroids making it a favorite in medical practices
due to its lower chance of abuse.
Mesterolone is generally well liked nonetheless as it delivers very few
side-effects in men. In high doses it can cause some virilization
symptoms in women. But because of the high level of deactivation and
pre-destination in the system (albumin, SHBG, 3bHSD, aromatase)
quite a lot of it, if not all simply never reaches the androgen receptor
where it would cause anabolic effects, but also side-effects. So its
relatively safe. Doses between 25 and 250 mg per day are used with
no adverse effects. 50 mg per day is usually sufficient to be effective
in each of the four cases we mentioned up above, so going higher
really isn't necessary. Unlike what some suggest or believe, its not
advised that PROVIRON-25 be used when not used in conjunction with
another steroid, as it too is quite suppressive of natural testosterone,
leading to all sorts of future complications upon discontinuation.
Ranging from loss of libido or erectile dysfunction all the way up to
infertility. One would not be aware of such dangers because
PROVIRON-25 fulfills most of the functions of normal levels of
testosterone.
