Testosterone Enanthate is probably the most
commonly used form of testosterone by both athletes and bodybuilders alike.
Although I don't have any hard statistics on this, Id be willing to bet that
this form of testosterone is the most commonly used form of testosterone on the
black market today. Its very effective for building muscle and strength, losing
fat, and is cheap & readily available.
To understand exactly how Testosterone Enanthate
enth" or just "enth") builds muscle and burns fat, first well
take a look at androgens and what they do in the body. You see, hormones are
substances secreted by one cell, that has an effect on the functions of another
cell. Testosterone is manufactured in the Leydigs cells of the testes (in men).
The adult male produces between 2.5 and 11mgs of Test per day.
Testosterone induces changes in shape, size and
also can change the appearance and the number of muscle fibres(7). Androgens
like testosterone can protect your hard earned muscle from the catabolic
(muscle wasting) glucocorticoid hormones(8), thus inhibiting their ability to
send a message to muscle cells to release stored protein. Remember,
Testosterone sends a message to muscle cells to store more contractile protein
(called actin and myosin); glucocorticoid hormones send the opposite message.
In addition, Testosterone has the ability to increase erythropoiesis (red blood
cell production) in your kidneys(9), and a higher Red Blood Cell (RBC) count
may improve endurance via better oxygenated blood. More RBCs can also improve
recovery from strenuous physical activity. Aggression levels often rise
dramatically with the use of exogenous testosterone (15).
All of these great benefits are to be had with
the use of Testosterone Enanthate alone, but realistically, it will be part of
a cycle containing one or more other drugs. People who are bulking will
probably choose Deca
or Eq (possibly with Dbol as well) and those who are cutting will probably
steer towards Eq and perhaps Trenbolone.
Very often users will shoot Testosterone Enanthate once or twice a week, but
blood levels are still above baseline with this drug at around day eight
(16).Common wisdom holds that the testosterone portion of any such cycle should
be equal to or greater than any other injectable drug(s) portion (on a mg
basis)... I believe that you can get away with less, but in general, this is a
As you may have suspected, Testosterones
anabolic/androgenic effects are dose dependent, the higher the dose the higher
the muscle building effect(10). Lets take a look at exactly what kind of
results we can expect from administration of Testosterone Enanthate:
Effects of 20 wk of GnRH agonist plus TE
administration on relative changes (mean SEM) in total LBM (A), appendicular
LBM (B), and trunk LBM (C) (percent change from baseline) measured by DEXA. P
values are results for ANOVA: *, P < 0.05 vs. all other dose groups for the
multiple comparison tests using Student-Newman-Keuls; a, P < 0.05 vs. zero
This chart shows that the subjects in this test
made a roughly 15% gain in Lean Body Mass from 20 weeks of 600mgs/week of
testosterone Enanthate. That's pretty impressive, but I feel that the following
set of charts is even more so:
Change in fat-free mass (A), fat mass (B), leg
press strength (C), thigh muscle volume (D), quadriceps muscle volume (E),
sexual function (F), insulin-like growth factor I (G), and prostate-specific
antigen (H). Data are means SE. *Significant differences from all other groups
(P < 0.05); significant difference from 25-, 50-, and 125-mg doses (P <
0.05); +significant difference from 25- and 50-mg doses (P < 0.05); and
significant difference from 25-mg dose (P < 0.05). (14)
Now this is very interesting. You'll note that
the most fat was lost by the group in this study who used the highest dose of
Testosterone Enanthate (600mgs/week), and the most Fat Free mass, Strength and
Muscle Volume was gained, when compared to any of the lower doses studied (14).
Basically, the more testosterone you use (and this holds true for almost all
steroids), the more gains you'll get! I know that the previous statement will
ruffle some feathers in the "less is more" club, but that's simply
too bad... more test = more muscle, more strength, more size, and less fat.
Did the men in this study experience side effects
at the 600mg dose? Well... HDL cholesterol was lowered (but not total
cholesterol or triglyceride levels), and two guys got Acne. Not exactly cause
for a Senate Investigation, huh? (14)
Of course, the usual nasty side effects you can
get from any form of injectable testosterone are possible with Testosterone
Enanthate (acne, hair-loss, prostate enlargement, and shutting down your body's
own natural hormonal system, etc...) but they are very overstated or
controllable in many instances.
A large percentage of those side effects occur
from the body's ability to turn testosterone into estrogen via a metabolic
pathway mediated by the aromatase enzyme. This process, known as aromatization
causes a portion of testosterone to be converted to estrogen. Aromatase
and Letroaole, for example) can combat this very effectively, and are usually
necessary with doses over a gram per week.
Now that Ive told you all about this drug, lets
talk about cost you should be paying no more than $75 for a 10cc bottle of
Testosterone Enanthate, dosed at 200-250mgs/ml. Of course, as usual, prices
fluctuate, but Id recommend sticking with a reputable underground lab, rather
then Organon, UpJohn, or one of the many other expensive (and often
counterfeited) companies. Testosterone Enanthate is relatively cheap to
produce, as the raw materials are very inexpensive, and as such, should be
reasonably cheap and especially since this drug should be a consideration for
inclusion in any cycle.
