Sustanon 250

A friend of ours, who jumped on to the TRT bandwagon a few months ago walked up to us the other day with a laundry list of concerns.

TRT was nothing like he’d expected it to be.

A couple of days after the pin, he felt like he was 18. Horny. Ready to fuck anything that moves. Energetic. Great mood.

But this kept tapering off until he felt like jack shit and was craving his injection three to four days before it was due.

Those four days were nothing short of miserable.

Turns out that he was prescribed Sustanon 250mg every two weeks.  

Does yours sound like a similar story? TRT with Sustanon and not quite getting what you expected?

What about using Sus 250 in a performance enhancement setting instead? Is it any better than the more popularly used single esters of Test?

Let’s find out.

Chemical structure

Sustanon 250 is a synthetic blend of four testosterone esters with different rates of release into the human body.

The precise breakdown is like this.

  • Testosterone Propionate, 30 mg
  • Phenylpropionate, 60 mg
  • Isocaproate, 60 mg
  • Decanoate, 100 mg

That’s a total of 250mg of Testosterone which will get released at different rates post the injection.

The faster acting esters, propionate and phenylpropionate will get released almost instantly, leading to a spike in Testosterone.

This is what makes you feel great in the days following your pin. The slower acting ester, Isocaproate gets released in the next few days, just as the effects of the faster acting esters are beginning to wane.

And then lastly, the slowest acting decanoate ester gets released.

The idea behind using a blend of Testosterone esters as opposed to a single ester is to keep the levels of testosterone stable, as well as to reduce the frequency of pins needed.

Common names

Sustanon is widely prescribed for TRT, particularly in the UK. So, you will most likely find the branded Sus 250 bottles in the black market.

The easy availability means that counterfeiting is not as common as it is with other steroids.

However, you need to be sure about the exact breakdown of the different esters in the blend.

It is Sustanon 250 only if the blend is exactly what we mentioned above.

Recently, there has been a deluge of cheap Chinese blends in the market which are labelled as Sustanon but do not contain these blends in precise proportions.

Main Uses

sustanon 250 results before after

Despite the fancy name, Sustanon 250 is just Testosterone.

And if you cannot find Test-E or Test-Cyp, then you can use it as a base for your maiden steroid cycle.

But if you can find a single ester form, then we would prefer that over Sustanon any day. The fluctuation in testosterone levels that happen with Sus-250 are just not worth it according to us.

Having said that, if you are starting your cycle with Sustanon 250, then here are some of the results that you can expect.

Lean Muscle Mass:

Testosterone is one of the best anabolic steroids for building lean muscle. The muscle growth will be slow and steady. With a good diet and exercise routine, you can expect to gain up to 10-15 lbs. of quality muscle. There will be some amount of water retention because it’s not a dry gain steroid, like Trenbolone. But you can control most of the bloat pretty easily and you can always club it with finishing compounds to dry you out during the last few days of the cycle.


Expect to get stronger as your Sustanon cycle progresses into week 4 and 5. The strength gains will be steady and sustainable.

Overall wellbeing:

If you are coming from a TRT dose, then you can expect a marked improvement in your quality of life. Your concentration improves. There will be fewer episodes of brain fog. You feel energetic. No lethargy all day.

Reduced body fat:

As Sustanon suppresses the level of glucocorticoids, it will lead to a reduction in the amount of fat you hold. This is an innate benefit of using testosterone which a lot of people don’t talk about. While it doesn’t directly burn fat, you start to look slimmer at the waist.

Side Effects

sustanon 250 side effects and alternatives

The side effects of Sustanon-250 are exactly the same as those caused by any form of exogenous testosterone.

The only difference is the sudden high followed by a crash which happens as the different esters get released in the body.


Sustanon will aromatize into estradiol, which eventually gets converted into Estrogen. So, if you are susceptible to Estrogen related side effects, then you will have to be wary of water retention and gynecomastia. Always have a SERM handy before you begin your steroid cycle. If you cannot control the estrogen levels with a SERM, switch to an Aromatase Inhibitor. The latter is more effective. But should be used only if necessary, to prevent your cholesterol levels from going awry.

Shut down:

Sustanon 250 will shut down the natural testosterone production completely. A full-fledged PCT with Nolvadex (and HCG) will be needed to stimulate the HPTA to restart the production of testosterone again. We also recommend M1MK and N2guard during cycle to provide necessary support.


Sustanon has a strong affinity to react with 5-alpha reductase, the enzyme which breaks it down to DHT. This leads to androgenic side effects in men who are susceptible to them. The side effects include acne, oily skin, spotty skin, body hair growth and accelerated hair loss on the head (Tip: Get N2Shampoo). Drugs like Finasteride may help, but only to an extent. If you are very sensitive to androgenic sides, then Sustanon is best avoided.

Dosage and stacks

Beginners should stick to 300-500mg/week of Sustanon for a 12-week cycle. This is a reasonably low dose and you ‘can’ combine it with other compounds. But if it’s your first cycle, stick to one compound only.

If you are a more experienced user, then you can increase the dose to 600-750mg/week if you are using Sustanon-250 alone. Not with other compounds, mind you.

Only professionals should think about using more than 750mg/week, as it greatly increases the risk of severe side effects.

Sustanon-250 can be stacked with a variety of other steroids, like Deca Durabolin, Winstrol, Anavar and Trenbolone.

Your choice of stacks should depend on your experience with steroids and your specific goals with each cycle.

Sustanon and Deca makes a great bulking stack that will also make you feel great. Throw in Dianabol for a kick starter.

Sustanon for 12-weeks with Winstrol added for the last 6-weeks. Will give you good muscle gains, while the Winny will chisel you out.

Sustanon, Deca and Trenbolone for complete body recomposition.
