by Anthony Roberts - Testoviron is a blend
of two different products,
Testosterone
Propionate (short ester) and
Testosterone
Enanthate (long ester).
Background
This product is manufactured by Schering. Blended
esters are the most expensive of all of the Testosterones
available due to the fact that they are rare as
well as in high demand. Testoviron can only be found
in the Dominican Republic and Italy (135mg versions
available in both countries).
Steroid Action
Testosterone is responsible for promoting health
and well-being through enhanced libido, energy,
immunity, increased fat loss, gaining and maintaining
lean muscle mass, preventing Osteoporosis (loss
of bone density) and possible protection against
heart disease. Testosterone is also responsible
for normal growth and development of male sex organs
and maintenance of secondary sex characteristics.
Secondary sex characteristics are specific traits
that separate the two sexes, but are not directly
part of the reproductive system, for example: chest
and facial hair, a distinguished jaw line, broad
shoulders and increased muscle mass. Testosterone
binds to the Androgen Receptors (AR), which thus
causes accelerated muscle gain, fat loss, and muscle
repair and growth. These mechanisms are stimulated
by activation of the Androgen Receptors (either
directly or as DHT).
There are many possible side-effects associated
with its use. This product also has a high level
of aromatization into estrogen and coverts to DHT
(dihydrotestosterone) as well. Also, supplementing
Testosterone to your body will result in the shutting
down of the body's natural production of the hormone.
The severity of side effects depend mostly on the
levels and duration of circulating free testosterone,
and its conversion to substrates. Testosterone's
anabolic/androgenic effects are dependant upon dosage,
the higher the dose the higher the muscle building
effect (and often, it’s side effects). Testosterone
promotes aggressive and dominant behavior.
Testosterone is
the best mass builder known to man and recommended
as the base of any mass building cycle.
Technical Data
Testosterone's anabolic/androgenic effects are
dependant upon the dose administered; usually the
higher the dose, the better the results (1). In
a study done on Testosterone Enanthate in this case),
a dose as high as 600 mg's (per week) produced better
results in subjects compared to those who received
all of the lower doses. At the highest dose, 600
mg/week, the greatest results were achieved in comparison
to any of the lower doses studied. The highest fat
loss, most muscle growth, and increased size and
strength were achieved at the higher dose (2). In
the same study, HDL cholesterol was lowered and
the subjects experienced acne. There was roughly
a 15% gain in Lean Body Mass from 20 weeks of 600mgs/week
of Testosterone therapy.
Overall, the most common report by subjects using
testosterone was immense gains in strength (3).
Alterations in size, shape, and appearance of the
muscle were reported (4).
Due to stimulation of the
Androgen Receptors (either directly or as DHT),
accelerated muscle gain, fat loss, increased muscle
repair and growth was experienced (5)(6). Testosterone
binds to the A.R. on fat cells; therefore, adipose
(fat) tissue can be broken down more readily while
new fat formation is prevented (7). Since the body
is building muscle at an accelerated rate, more
ingested food is shuttled directly to the muscle
tissue (this is known as nutrient portioning) and
away from fat. This is another indirect effect of
testosterone on fat loss. Testosterone also promotes
glycogen synthesis, which is activated by insulin
in response to high glucose levels (8). Glycogen
provides fuel to the muscle; therefore endurance
and strength increases were reported during severe
muscle breakdown in intense training and workouts.
Testosterone also converts to both Estrogen (through
Aromatization) and Dihydrotestosterone (through
5a-reduction). Most of the side effects people experience
with testosterone use is actually from it’s conversion
to these two substrates. Hair loss, water retention,
acne, and other side effects are possible with use
of this drug.
Also noteworthy is that testosterone administration
causes the shutdown of natural testosterone production.
User Notes
Testoviron is actually a very decent anabolic,
and is very rarely counterfeited any longer. Basically,
what we’re looking at is a nice pre-mixed blend
of Testosterone with a long ester (Enanthate) and
a short ester (Propionate). If I were personally
to make my own test blend to use every other day,
it would most likely be something very similar to
Testoviron.
The short ester will give you a nice spike in
testosterone levels, albeit one that decays very
quickly, while the longer ester will allow a very
slow decay in blood plasma levels.
One of the primary advantages to this version
of testosterone is that it is very rarely faked
because products like
Sustanon (a 4 ester blend) fetch a higher price,
and if you’re going to counterfeit an amp, it may
as well be the one which will earn you the highest
profit for your trouble. This is why we never see
counterfeit “Sten” amps (a
very low dosed preparation of testosterone) and
this basically holds true for Testoviron as well.
If you can find it, and it’s not any more expensive
then single ester testosterone, Testoviron is a
very nice buy on the black market.
