(Testosterone Mixture)

Developed by Organon for the purpose of Testosterone Replacement Therapy (TRT) Sustanon-250was at one time deemed the ultimate in achieving total TRT therapy in the most efficient means possible. The premise was simple; provide a testosterone based compound that would only need to be administered once every few weeks by combining multiple esters into one single compound for a steady continuous release of the testosterone hormone and the premise proved to be successful. The compound was so successful the individual could effectively inject the hormonal compound only once every 3-4 weeks and maintain a release of testosterone into the system but while a success it was not as perfect as it was hoped to be. Sustanon-250 is simply testosterone, in the same light of Testosterone-Cypionate, Testosterone-Propionate or any other form you can think of; Sustanon-250 is simply testosterone. In Sustanon-250 what you have is a testosterone mixture, four different esters attached to the same hormone; this does not change the hormones nature, it is just as anabolic and androgenic as it would be with only one ester attached but it’s mode of action in-terms of time regarding both initial activity and total duration is a very different story. While Sustanon-250 will provide a steady release of testosterone for extended periods of time by injecting only once every few weeks it is very difficult if not impossible to maintain a stable testosterone level and this can be very important to the performance enhancer and should be worthy of understanding to the TRT patient as well. Even though far extended spaced out injections may not be the best course of action as was once thought there is no doubt about it, Sustanon-250 is a fine testosterone hormone and can get the job done regardless of your individual purpose.


As a four part testosterone Sustanon-250 is comprised of Testosterone-Propionate, Testosterone-Phenylpropionate, Testosterone-Isocaproate and Testosterone-Decanoate in very specific amounts of each comprising of one total 250mg/ml testosterone compound. When you find Sustanon-250, while this is the original Organon trade name you will find many brands carry this title as well or at least a very similar one but regardless the total mixture should look exactly as follows:

  • Testosterone-Propionate: 30mg
  • Testosterone-Phenylpropionate: 60mg
  • Testosterone-Isocaproate: 60mg
  • Testosterone-Decanoate: 100mg

To understand the Sustanon-250 compound we only need to understand two specific things; the testosterone hormone itself and how the esters attached affect it; as you understand testosterone in of itself is the same across the board, it is the esters that vary. In that light, as a four part mixture the design is intended to provide active testosterone in a very quick fashion, as is allowed by the attached Propionate and Phenylpropionate esters and to continue the duration of release for a far extending period of time through the following two longer esters; Decanoate being the longest of all. Because of the mixtures variation the user will enjoy an almost instant benefit and one that stretches into a total 18 day half-life in total activity; however, as we will see, although a very long total half-life we cannot view this in the traditional half-life sense of other testosterone forms and frequent injections will often prove to be very necessary. As for the direct mode of action regarding the properties of Sustanon-250 the individual will find them to be the same as all testosterone forms, as Sustanon-250 is just that; pure testosterone. As pure testosterone Sustanon-250 is highly anabolic and androgenic, equal on both parts. By its nature as a pure testosterone it will greatly enhance nitrogen retention and overall protein synthesis as well as increase red blood cell count; all very important and intrinsic qualities regarding total anabolic activity. Testosterone also greatly affects the release of the anabolic IGF-1 hormone, therefor whentestosterone levels increase more anabolic activity is brought to the table. Further, testosterone has a very positive effect on muscle wasting hormones such as cortisol; cortisol buildup and release is actually inhibited when testosterone is present in adequate amounts, thereby leading to a higher level of total anabolic activity and promoting a physique more apt to building muscle and simply looking and feeling better.

The Benefits of Sustanon-250:

The single most important benefit of Sustanon-250 revolves around the purpose of its original intent; to provide long standing yet steady release of the testosterone hormone in order to limit administration frequency. For the TRT patient this can be quite convenient but in recent years it has fallen out of popularity as it is very hard to maintain a peaked level of the hormone and most physicians will end up prescribing single ester based testosterones such as the Enanthate or Cypionate version, with Testosterone-Cypionate being very common for TRT in the U.S. For the performance enhancer this time released quality will however prove to be of very little use, for this individual must inject the hormone at a minimum of every three days if he is to maintain not only stable levels of testosterone but peaked and stable levels. As you understand the hormone you can easily determine how injection frequency will best serve you and once this is determined you can easily bring forth the therapeutic needs you desire. For the TRT patient who suffers from low testosterone he will see on the benefits for which testosterone is responsible for improve; this includes muscle mass and strength, sexual function including desire and erectile function, overall metabolic activity, energy, immune function and even your general sense of well-being. For the performance enhancer the same can be said, simply to a stronger degree. For the performance enhancer Sustanon-250 can be the perfect steroid for any cycle as it will aid in building mass and strength but will also aid in the leaning out process by way of preserving muscle tissue when on a calorie restricted diet and even improving the rate in-which body-fat is lost in the first place leading to an more impressive physique as well as a more functional one.

The Side-Effects of Sustanon-250:

If it’s an anabolic androgenic steroid it will carry with it the possibility of negative side-effects and as Sustanon-250 is pure testosterone and as testosterone is the father of all anabolic androgenic steroids, you bet, it carries with it possible side-effects. However, it is also important to keep in mind when speaking of testosterone we are speaking of a hormone we naturally produce, we are not speaking of a foreign substance our body is unfamiliar with; in-fact, while there are possible side-effects you’ll find many over the counter medications commonly carry with them the possibility of far worse side-effects than testosterone and a far greater probability. That is correct, probability plays a role and with responsible use of Sustanon-250 or any testosterone and for that matter most anabolic steroids, side-effects can easily be avoided or at least easily controlled. As for the actual side-effects themselves, they will be the same as all testosterone forms, as the testosterone hormone aromatizes greatly and by this aromatase process converts to estrogen. As this conversion occurs and estrogen levels increase such estrogenic related side-effects can occur including Gynecomastia, excess water retention, high blood pressure and issues of a cholesterol nature. These side-effects can be very easily controlled and some will need no method of control as their response will be so positive no negative effect will be found. For those who do experience a buildup of estrogen an good aromatase inhibitor (AI) is highly advised as by the use of an AI you will inhibit the aromatase process from occurring as well as reduce the amount of estrogen in your body; what doesn’t exist cannot cause a problem. One’s diet will also play a large role and to maintain a healthy blood pressure and cholesterol levels it’s always a good idea to follow a diet rich in healthy fats, particularly omega fatty acids. There is however another side-effect to Sustanon-250 use and it is and will occur with all testosterone and all anabolic steroids for that matter; testicular atrophy. When anabolic steroids are present in the body they suppress natural
