Sustanon 250 is a popular testosterone blend (mixture) and is without question the most popular and well known blend ever made. Manufactured by Organon, the idea behind Sustanon 250 was to provide the best of small (short) and large (long) ester testosterones in a single compound. This would allow the individual to maintain stable blood levels of the testosterone hormone with an infrequent injection schedule while simultaneously receiving fast acting benefits._x000D__x000D_ Test 600xThe limited injection frequency makes Sustanon 250 a perfect compound for the treatment of low testosterone. It allows the individual to maintain stable levels without the need for constantly pinning themselves with a needle, but this is truly the only advantage of this testosterone. Sustanon 250 will not provide any advantage over a single ester testosterone compound to a performance athlete. In a performance capacity we will find the individual will still be required to inject the hormone frequently if he is to maintain not only stable blood levels but peaked blood levels. Many often inaccurately assume Sustanon 250 is superior over single ester testosterone forms due to the fact that it carries four distinct testosterones in a single injection. As for the basic functioning traits of testosterone, they will be the same with Sustanon 250 as they are with all testosterone forms. They will be no more or less powerful or effective._x000D__x000D_ Sustanon 250 is a testosterone hormone. Although synthetic it is a perfect replica of the naturally produced primary male androgen testosterone. By the esters that are attached, this is what defines Sustanon 250 and differentiates it from other testosterone compounds. The compound carries a mixture of small and large esters in a precise dose. It is the precise dose of each of the four testosterone esters that make it. You could take four other testosterones and combine them in the same dosing strength but this would not make it Sustanon 250._x000D__x000D_ _x000D__x000D_ Sustanon 250 is an oil-based injectable Testosterone blend. Sustanon developed by the international drug firm Organon. The substance typically contains four different Testosterone esters: Testosterone propionate (30 mg); Testosterone phenylpropionate (60 mg); Testosterone isocaproate (60mg); and Testosterone decanoate (100 mg), although a lower dosed version is also produced. An intelligently “engineered” Testosterone, Sustanon is designed to provide a fast yet extended release of Testosterone. The propionate and phenylpropionate esters are quickly utilized, releasing into circulation within the first four days. The remaining esters are much slower to release. Sustanon stayes active in the body for about two and three weeks (respectively). This is a big improvement of Sustanon from standard Testosterones such as cypionate or enanthate, which provide a much shorter duration of activity, and a more variable blood level._x000D__x000D_ _x000D__x000D_ This is important because there are underground labs that try to pass off other mixtures as Sustanon 250. The precise makeup of Organon’s product is as follows:_x000D__x000D_ _x000D__x000D_ Sustanon 250 Dosages_x000D__x000D_ 250mg per Week_x000D__x000D_ At a usage level of 250 mg/week, Sustanon provides basically only a high level of testosterone replacement therapy. Individuals with low testosterone may see a marked improvement, but many with mid-normal or high natural testosterone will see little added effect at this dosage level. Yet, Sustanon is suppressive of the hypothalamus and pituitary at this dosage and will largely shut down natural testosterone production while being used. So, this dosage has relatively little of the benefits of most steroid cycles, but shares the adverse side effect of suppressed testosterone production._x000D__x000D_ _x000D__x000D_ This is one of the longest ester used in any steroid. It has a very long half-life, over 2 weeks (around 15 days), which means the active life of the ester is almost a month. In simple terms, from the time you inject decanoate, it takes roughly 30 days to leave your system. Though, you can expect the peak of this ester to be around 11-12 days not 15._x000D__x000D_ Interestingly, the decanoate ester is the main reason sustanon is considered a “once a month” drug. Users tend to think you can inject one injection of sustanon per month based on this ester alone. This is true for testosterone replacement therapy (TRT), but it’s a complete fallacy for bodybuilding. Think of it this way, by the time you get to day 11-15 (~2 weeks in), you peaked and you used up most of the steroid. Therefore, you need another injection to keep blood levels steady.
