Sustanon 250 is a trade name for an oil-based injectable blend of four esterized testosterone compounds:
30 mg testosterone propionate
60 mg testosterone phenylpropionate
60 mg testosterone isocaproate
100 mg testosterone decanoate
Sustanon-250 is a testosterone mixture first developed by Organon in an effort to create a more suitable testosterone for hormone replacement therapy. The idea was simple; create a testosterone that can be injected less frequently and still keep levels at a steady rate over a long period of time. The good news for HRT patients is the idea became a reality; the bad news for the performance enhancer is this does not help them at all. Were not saying Sustanon-250 is useless to athletes, far from it but the time release principles are of very little value to them because they will necessarily need more testosterone than an HRT patient and will need to keep levels at a maximum range; well explain as we go along.
The Sustanon-250 Mixture
Most testosterones are defined by their name; for example, Testosterone-Enanthate is called so because it is a testosterone with the Enanthate ester attached; pretty simple. However, there is no Sustanon ester, Sustanon-250 refers to a blend of 4 varying ester based testosterones each with a varying half-life mixed together in varying doses. The total mixture, which gives us 250mg per milliliter is as follows:
Testosterone-Isocaproate - 60mg
With this mixture we have two relatively fast esters in Propionate and Phenylpropionate, a moderate size ester in Isocaproate and a very long ester in Decanoate. Once injected testosterone will be released at a fairly even rate regarding milligrams for a month, making this a near perfect HRT medication but for performance purposes this will not do. Because of the short esters attached, to maintain peak testosterone levels Sustanon-250 must at a minimum be injected every three days with every other day administration being far more optimal because of the Propionate ester attached.
Sustanon-250 & Omnadren
Many steroid users who supplement with Sustanon-250 find Omnadren to be equally effective; in-fact, almost everything that can be said of Sustanon-250 can equally be said of Omnadren; these two testosterone mixtures are almost identical in action. The only significant difference is one ester; while the longest ester in Sustanon-250 is Decanoate the longest ester in Omnadren is Caproate. The dosing of each ester in each blend is exactly the same; Omnadrens final Caproate ester is dosed at 100mg just as the Decanoate ester is in Sustanon-250. However, because Caproate carries with it a shorter half-life than Decanoate Omnadrens total half-life is going to be approximately ten days while Sust as its commonly called will carry a total half-life of approximately 15 days.
The benefits of Sustanon-250 are the same as any testosterone be it a single ester or testosterone blend such as Omnadren or Testoviron. All testosterone users of all forms can greatly increase lean muscle tissue as well as increase strength and vitality. Further, as testosterone is a key component in maintaining muscle mass in a calorie restricted diet it is the perfect hormone when we are trying to lean out. Further, because testosterone blocks and reduces muscle wasting hormones that buildup in the body, overall, regardless of the purpose of use we inevitably create a more pleasing physique when testosterone levels increase.
There is however a risk to reward ratio that is in play and it applies to all testosterone; Sustanon-250 makes no exception. The principle is simple; the more you use the greater the benefits will be but the more you use the greater the risk of nasty side-effects. Yes, Sustanon-250 carries the exact same side-effects of all testosterone compounds, the same as Testosterone-Enanthate, Testosterone-Cypionate or any other single ester or mixture you may desire to use. All testosterone use opens the door for an aromatizing effect so estrogenic related side-effects will always be a concern. Issues such as Gynecomastia, high blood pressure, water retention and other estrogenic effects such as decreased sex drive can occur. This is why it is of utmost importance to use a good aromatase inhibitor when supplementing with testosterone; by doing so, coupled with using responsibly we greatly improve our chances of positive and enjoyable use.
Sustanon injection contains testosterone esters. These are derivatives of the naturally occurring male hormone testosterone. They are converted in the body to testosterone.
Testosterone is known as an androgen. It is produced by the testicles and is the main hormone essential for normal growth and development of the male sex organs and male sexual characteristics.
The natural production of testosterone is controlled by another set of hormones called gonadotrophins, which are released from the pituitary gland in the brain.
During adult life, testosterone is essential for the production of sperm, the maintenance of sex drive, erectile potency, and the functioning of the prostate gland and other reproductive structures. It also has functions in the skin, muscles, skeleton, kidney, liver, bone marrow and central nervous system.
Low levels of testosterone can cause decreased sex drive, impotence, infertility due to decreased sperm production, decreased mental and physical activity, fatigue and weakening of bones.
Testosterone is given as replacement therapy when natural testosterone levels fall too low, causing symptoms such as those above. Natural testosterone levels fall with age and following surgical removal of the testicles (castration). They may also fall due to decreased functioning of the testicles (hypogonadism or eunuchoidism) caused by testicular disease, or by decreased gonadotrophin production by the pituitary gland, as a result of pituitary disease.
Testosterone replacement allows natural testosterone levels to return to normal, thus relieving the symptoms of the deficiency.
Sustanon injection is called a depot injection. It is injected slowly into the muscle where it forms a reservoir of medicine. The testosterone is gradually released all the time from the reservoir into the bloodstream. The injection is usually given once every two to three weeks, though the frequency will depend on your individual testosterone levels.

For more information about any other possible risks associated with this medicine, please read the information provided with the medicine or consult your doctor or pharmacist.
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before starting treatment this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while on this treatment, to ensure that the combination is safe.
Testosterone may increase the anti-blood-clotting effects of anticoagulants such as warfarin, nicoumalone and phenindione. If you are taking any of these your blood clotting time (INR) may need to be monitored more frequently; in particular it should be measured after you start or stop testosterone treatment.
If testosterone is used in combination with corticosteroids such as dexamethasone, there may be a greater chance of fluid retention and oedema since both medicines can cause fluid retention. This combination of medicines should be used with caution in people with heart, liver or kidney disease.
If you have diabetes, your dose of insulin or antidiabetic tablets may need to be reduced after you start treatment with this medicine.
