Testosterone Enanthate is one of the many esterified variants of Testosterone available. It is an injectable compound with a slow rate of release due to the larger Enanthate ester attached to the Testosterone molecule. This augments the release rate and half-life of Testosterone to that of a slower release. The majority of Testosterone products that have been designed are single products that contain a single esterified form, as opposed to Testosterone products which consist of a blend of several different esterified variants in the liquid (such as Sustanon 250, for example). Testosterone that is un-esterified holds a very short half-life, making its use very inconvenient and impractical (Testosterone suspension is one such Testosterone product that consists of pure un-esterified Testosterone, and does not have an ester bonded to its structure). The Enanthate ester expands Testosterone’s half-life to that of 10 days, and blood plasma levels of the hormone remain elevated for a total period of approximately 2 – 3 weeks. Testosterone itself is considered the most natural and safest anabolic steroid any individual can use, and it is easily the most versatile and flexible anabolic steroid in terms of how it can be utilized in cycles and for different purposes and goals.
The Enanthate variant of Testosterone had first been described in the early 1950s when it had landed on the market and experienced increasingly extensive use shortly thereafter. This was the very first injectable Testosterone ester preparation that provided slower release rates. Prior to the development of Testosterone Enanthate, the most widely utilized forms were either un-esterified Testosterone (Testosterone suspension) or the faster acting Testosterone Propionate, which holds a half-life of approximately 4.5 days, necessitating more frequent injections which can be inconvenient for many. As such, Testosterone Enanthate promptly replaced Testosterone Propionate as the Testosterone of choice by the medical establishment in the West, as well as athletes and bodybuilders utilizing it for performance and physique enhancement. In the United States, Delatestryl manufactured by Squibb was the very first Testosterone Enanthate product to be marketed, and it is still manufactured and marketed today only under different pharmaceutical manufacturers that have purchased the rights to market that name brand. Most recently 2005, for example, Indevus was the latest pharmaceutical company to manufacture and market the drug. Internationally (outside of North America, mostly) the brand name for Testosterone Enanthate is known as Testoviron, which unlike Delatestryl, has been manufactured by Schering ever since its original inception well over 50 years ago. Ultimately it is the Testoviron brand name that is the most popular and widely utilized Testosterone Enanthate product in the world.
Testosterone is the king of all mass builders and for this purpose is also fairly cost effective. It works well either alone or stacked to create a great bulking cycle. It has a high risk of side effects due to its conversion to DHT and has the potential to form estrogen, causing gynecomastia. These characteristics also cause it to have such excellent mass building tendencies. Due to some other side effects, such as water retention, it may not be the best used alone for lean mass gains, but with bulking comes the addition of a lot of muscle as well as some gains in fat and water weight. This is typical and a natural part of the enhanced bodybuilder’s bulking regiment.
Testosterone Enanthate is a long lasting single ester steroid. It is 7 carbons in length. What this means, is that more of the weight of the steroid is testosterone as opposed to ester weight. When taking a quantity of an esterified steroid, the total weight is a combination of both the ester weight and the steroid. That said, longer esters such as Cypionate have more ester weight (due to it’s 8 carbon length), and less overall steroid weight. For this reason, Enanthate would be preferred over Cypionate. Sustanon has even more steroid weight.
500 mg of Enanthate has more free based testosterone than 500 mg of Cypionate and 500 mg of Sustanon has more than either. However, due to the irregular release of Sustanon and the need to inject more frequently to take full advantage of the propionate and phenylpropionate esters and thereby make full release of the steroid itself, either Enanthate or cypionate will be better choices for the first time user, who will likely want to maintain stable blood levels of the steroid while minimizing injection frequency.
A long acting testosterone ester will be very helpful for your bulking needs and Enanthate is a product which is more simple than some of the other steroids out there. Not to say it is without its share of complications, but it’s a good choice, especially for those new to enhanced bodybuilding. Discontinuing the product is not an option in case side effects occur, because it will continue to aggravate these side effects over extended periods of time due to the long length of action of this steroid (3-4 weeks). Ancillary drugs such as Nolvadex, Proviron, Clomid and HCG may help, both during cycle and post cycle to help restore natural testosterone production. Testosterone Enanthate does aromatize slightly more than Sustanon, but when using either drug, one should be familiar with anti-estrogen’s such as Nolvadex or Clomid and use one of them when symptoms of gyno occur.
Those who have prostate problems or those who are sensitive to gyno (for example, those who developed a case of gyno during puberty), and those who are sensitive to female pattern fat deposits will want to ensure anti-estrogens are on hand during cycle in case gyno related side effects arise. As a general rule of thumb, you will always want to keep nolvadex on hand – but obviously, it is even more important if the risks of these side effects are higher than normal (depending on the user and his or her genetic predisposition).
Like any other testosterone, Enanthate suppressed HPTA function. Clomid or Nolvadex are important to have post cycle to stimulate normal testosterone function within a reasonable amount of time. You may also want to use HCG during your cycle, but this is matter of personal preference, as many feel they will be able to recover post cycle and don’t feel the benefit of HCG is worth the cost. Normalization of natural functions which were suppressed during cycle and testosterone production usually occur without the use of HCG, but at a slower rate than if it was used. Like anything in life, there is no guarantee of full recovery, but it would be a rare case if it did not happen.
Weekly totals of 250-1000mg weekly are frequently used, and sometimes more for the highly advanced athlete. Due to the relatively long half life of Enanthate (4-5 days), injections are usually administered twice per week. This will allow stable blood levels to be maintained. When the level of steroid tapers down, a new injection is made, keeping everything fairly level. This is unlike Sustanon, which requires more frequent injections for the same effect. For a first cycle, 500mg alone of Testosterone Enanthate, shot two times weekly (Monday and Thursday for example), for 10 weeks along with standard post cycle therapy would be very sufficient for good gains.
