While Testosterone Cypionate is the preferred form of Testosterone for TRT in the United States, it’s Sustanon 250 in the United Kingdom.
Sustanon 250 is a blend of four testosterone esters with different release rates, which was specially formulated for TRT use by Organon.
The idea behind the development of a blend of esters is to reduce the frequency of pinning.
While the shorter acting esters provide an instant spike in Testosterone levels, the medium and slow acting esters kick-in over a period of fourteen days which allows the user to limit the injections to one every fortnight.
Sustanon 250 is rarely used in a performance enhancement setting. But if the other single esters of Test are unavailable with your supplier, or you wish to experiment with a blend for a change, then this brief guide will explain to you the key differences, as well as how to use Sustanon safely.
What is Sustanon 250?
Sustanon 250 is a precise blend of four Testosterone esters.
It is an oil-based injectable that delivers 250mg of Testosterone in 1 millimeter of the drug.
A 1ml dose contains:
- 30 mg Test Propionate
- 60 mg Test Phenylpropionate
- 60 mg Test Isocaproate
- 100 mg Test Decanoate
Any other combination of esters is not Sustanon.
It is the preferred Testosterone replacement drug in the United Kingdom as well as in many other parts of Europe.
The advantage of using a blend is that the different esters have different release rates.
When a person takes his TRT dose of Sustanon, the Propionate ester releases Testosterone into the bloodstream instantly.
This allows the person to feel better due to the spike in Testosterone.
When the levels of Testosterone begin to dip, the Phenylpropionate and Isocaproate esters release more test, thereby maintaining a more or less consistent level of the hormone in the blood.
Lastly, the slow acting Decanoate ester releases after 10-12 days, following which the dosage is repeated.
Depending on the prescribed dose, Sustanon injections may be given once a week or once every two weeks.
Can Sustanon 250 be used for performance enhancement?
Yes. Why not?
Despite the fancy labelling and all the talk about the blend, Sustanon is essentially plain old Testosterone.
As long as you are looking to run a test cycle, you can run any form of it. Sustanon fits the bill.
That said, the effects, or the time taken to feel those effects, can vary greatly.
When it comes to Sustanon 250, the slow timed release of the different esters can cause peaks and drops in your testosterone levels over a fortnight, which can be pretty harsh if you aren’t used to it.
Think of it like feeling great for a couple of days and then feeling like shit again until the next ester releases.
Despite what the manufacturer wants you to believe, the releases of the different esters are not seamless.
Also, there will be a cascade of hormones to deal with. When Test increases, so does aromatization and estrogen.
You will have to play around with the AI dosage until you dial it down to perfection.
Like we said, it’s not impossible. But it’s not easy either.
A simpler way is to run a single ester of Testosterone that will be a lot easier to time and control.
How to use Sustanon 250 in a steroid cycle
If you have your mind set on using Sustanon 250 in a steroid cycle, then the least you can do is run it properly.
Like we mentioned earlier, the idea behind the blend is to reduce the frequency of pins.
But given that most steroid users would be using at least 500mg/week of test, you are looking at two injections of Sustanon in a week.
You can do this Monday and Friday.
You’d also want to dial down on your AI dosage, which is individualistic depending on how sensitive you are to estrogenic sides.
A good starting dose is around 10mg of Aromasin every day.
What are the results that you can achieve with Sustanon?
Sustanon is a great foundational steroid that can be used as a base in a steroid stack.
It can also be run solo for beginners.
If you run a solo cycle of Sus, it will increase Nitrogen retention, the production of RBC which improves oxygenation and nutrient delivery to muscles and it will suppress glucocorticoid hormones which catabolize muscle.
You will also notice a marked improvement in your strength, aggression and performance.
Your libido will skyrocket and your confidence will improve.
If you have been struggling with the symptoms of Low T, then this will transform your life.
If you are careful about your diet, you can easily gain up to 15 lbs. on your first Sustanon cycle.
How long should you run a Sustanon cycle?
Due to the different release times and esters, Sustanon will take at least 5-6 weeks to get fully saturated in your system.
In other words, it will be at least 6-weeks by the time you feel it.
You should run it for at least 12-weeks. Remember that you will still feel the effects of the steroid for two to three weeks after you stop using it.
That’s when you should start with a PCT protocol.
Can Sustanon cause gyno?
Sustanon can cause all of the side effects that Testosterone can.
So yes, it can cause gynecomastia as it will aromatize readily into Estrogen.
You will need to use an AI during the cycle to minimize estrogenic side effects.
Do you need a PCT with Sustanon?
Oh yes, you do.
Sustanon will shut down your endogenous testosterone production even with 1 injection.
A Post Cycle Therapy or PCT will allow your body to kick start the testosterone production a lot sooner than it would do on its own.
There are different schools of thoughts out there about the right timing for PCT with Sustanon.
Some users feel that 4-weeks after the last pin is the way to go. Others recommend starting two weeks after your last pin.
Nolvadex at 40/40/20/20 for four weeks is a tried and tested PCT protocol that works every time.
