If Sustanon 250 is your tentative steroid of choice, then your knowledge of the Sustanon 250 ingredients will be crucial in your decision making process.



Whether you are an experienced bodybuilder looking to start a single or stacked steroid cycle or you are just a rookie in the world of bodybuilding and you want to start out your program with the use of anabolic steroids. It is important to take time out to know exactly what you are getting before you either pop that wonder pill or inject the steroids deep into your muscles. Knowing the constituents of your chosen steroid(s) will help you in determining whether the drug is good for you or not.

If Sustanon 250 is your tentative steroid of choice, then your knowledge of the Sustanon 250 ingredients will be crucial in your decision making process.


Sustanon 250 is an androgenic anabolic steroid (AAS) that is administered by injection. This drug is a fundamental steroid and can be used alongside other anabolic steroids like Anavar and Dianabol.

Sustanon is a testosterone booster anabolic steroid solution in oil with every ampoule consisting of 1 ml arachis oil. It is also available in 250mg/ml vials. The solution that is contained within the vials come in a clear, but pale yellow colour.


You may be wondering what the active Sustanon 250 ingredients are?

With Sustanon, just 1 ml of arachis oil consists of four different testosterone esters of varying milligrammes.

The active Sustanon 250 ingredients include:

  • Testosterone propionate (30 mg),
  • Testosterone phenylpropionate (60 mg),
  • Testosterone isocaproate (60 mg),
  • Testosterone decanoate (100 mg)

The four testosterone esters listed above form the main active ingredients of Sustanon 250. These testosterone esters are also naturally produced by the male testicles when it generates the testosterone hormone in the body. Apart from these main Sustanon 250 ingredients, there are also two excipients worth mentioning. One of these excipients has already been mentioned and that is the carrier oil (arachis oil) while the other one is Benzyl alcohol.


As a Sustanon dosage is administered, the testosterone propionate ester of the active Sustanon 250 ingredients will instantly release a dose of testosterone directly into the user’s bloodstream.

The user will immediately be overwhelmed with a sense of relief, mainly as a result of the sudden rise in their testosterone levels.

As the person’s testosterone levels start to drop, both the testosterone isocaproate and phenylpropionate esters will further release additional testosterone to ensure that the testosterone hormone level of the user does not drop below what should be a normal level.

Between 10 to 12 days, the testosterone decanoate ester which is generally slow in acting, will release more testosterone into the user’s bloodstream.

Sustanon dosage may vary due to several reasons. Typically, a single 250mg/ml dosage is administered once in 3 weeks.

Alternatively, if you are a bodybuilder with a normal testosterone level, you may run an 8 to 12 week Sustanon cycle consisting of between 500 and 1,000mg/ml per week. This is where you are using only Sustanon, but if you are using this AAS with other steroids, then a dose of 250mg/ml per week for the duration of your steroid stack cycle would suffice.
