Testosterone Enanthate is probably the most commonly used form of testosterone by both athletes and bodybuilders. It’s very effective for building muscle and strength, losing fat, and is cheap and readily available.

To understand exactly how Testosterone Enanthate (a.k.a. “test enth” or just “enth”) builds muscle and burns fat, we’ll take a look at androgens and what they do in the body. You see, hormones are substances secreted by one cell, which has an effect on the functions of another cell. Testosterone is manufactured in the Leydig’s cells of the testes (in men). The adult male produces between 2.5 and 11mgs of Test per day.

Testosterone induces changes in shape and size, and also can change the appearance and the number of muscle fibers (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 test enth alone, but realistically, it will be part of a cycle containing one or more 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 this drug 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).

As you may have suspected, Testosterones’ anabolic/androgenic effects are dose dependant, the higher the dose, the higher the muscle building effect (10).
In the tests a roughly 15% gain in Lean Body Mass from 20 weeks of 600mgs/week of testosterone Enanthate was made. Additionally you’ll note that the most fat was lost by the group in this study who used the highest dose (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 you’ll gain! I know that the last statement will ruffle some feathers in the “less is more” club, but that’s 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 men got acne. (14). Of course, the usual nasty side effects you can get from any form of injectable testosterone are possible with testosterone enanthate (acne, hairioss, 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 inhibitors (Arimidex and Letroaole, for example) can combat this effectively, and are usually necessary with doses over 1/2 a gram per week.

This drug is relatively cheap to produce, the raw materials are very inexpensive, and should be reasonably cheap, especially since this drug should be a consideration for inclusion in any cycle. Of course, as usual prices fluctuate, but I’d recommend sticking with a reputable underground Lab, rather then Organon, UpJohn, or one of the many other expensive (and often counterfeited) companies.
