01The basics
What Zionova Sustanon 250 is
Sustanon 250 is a blend of four testosterone esters in one oil: testosterone propionate, phenylpropionate, isocaproate and decanoate. The short esters raise testosterone within a day or two, and the long ones keep it raised for weeks. Each 10 ml Zionova vial contains 250 mg of testosterone esters per ml, 2,500 mg in total.
The original Sustanon was developed by Organon for testosterone replacement and is still prescribed in many countries. It’s also one of the best-known testosterone products in bodybuilding. Whatever the reason you’re using it, the effects and risks are those of testosterone, so this page covers both, plus the bloodwork to get.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.
03How it works
How it works
Every ester in the blend releases the same hormone, testosterone. What differs is speed:
- Propionate is the fastest, active within about a day.
- Phenylpropionate and isocaproate fill the middle, over several days to a week or so.
- Decanoate is the slowest and keeps releasing for up to about three weeks.
The original pharmaceutical formula uses 30 mg propionate, 60 mg phenylpropionate, 60 mg isocaproate and 100 mg decanoate per ml. Once released, testosterone acts like your own: it builds muscle protein, raises red blood cell production, and partly converts to estradiol (estrogen) and DHT.
04Clinical reference
Dosing information
Clinical reference. Where Sustanon 250 is prescribed for low testosterone, the label’s usual dose is 1 ml (250 mg) every three weeks, adjusted to symptoms and bloodwork. Because the fast esters peak early and the slow one tails off, levels rise and fall a lot over those three weeks, so many people split the same total into smaller, more frequent injections for steadier levels.
Doses used for muscle building are usually well above replacement, and every risk on this page rises with dose.
Talk to a doctor before use, and get bloodwork before, during and after.

06Injection sites
Where it is injected
Sustanon 250 is an oil, so it goes deep into a large muscle with a regular needle: never just under the skin and never into a vein. These are the muscles standard nursing guidance uses.
1Hip (ventrogluteal)Gluteus medius and minimusIM
Volume per siteUp to 3 mlNeedle1–1.5 in, 22–25G
- Lie on your side or stand. Put the heel of your hand on the bony knob at the top of the thigh (greater trochanter): left hand on the right hip, right hand on the left.
- Point your index finger at the bony front of the hip (anterior superior iliac spine) and fan your middle finger back along the hip crest to make a V.
- The site is the middle of that V.
Why it is used. Many nursing programs now teach it first. The muscle is thick, the fat over it is thin and fairly even, and no large nerve or vessel crosses the target area.
Careful. The landmarks take a few tries to find on your own body. A mirror or a helper makes the first ones easier.

2Outer thigh (vastus lateralis)Vastus lateralis, quadricepsIM
Volume per siteUp to 3 mlNeedle1–1.5 in, 22–25G
- Sit down. Find the bony knob at the top of the thigh and the top of the kneecap.
- Divide the distance between them into three equal parts.
- Use the middle part, on the outer front of the thigh, roughly where a trouser seam would run.
Why it is used. The easiest large muscle to see and reach on yourself, with plenty of muscle to work with.
Careful. Stay on the outer side. The femoral artery, vein and nerve run along the inner front of the thigh. It can feel stiff for a day or two.

3Shoulder (deltoid)DeltoidIM
Volume per siteUp to 1 mlNeedle1 in, 23–25G
- Find the bony ridge at the top of the shoulder (acromion).
- Measure two to three finger-widths straight down from it.
- Inject into the thickest part of the muscle on the outer side of the arm, well above the armpit line.
Why it is used. Quick to reach and the usual place for vaccines. Good for small volumes.
Careful. A small muscle: larger amounts hurt and can leak back out. Going too low on the arm risks the axillary and radial nerves.

!Upper buttock (dorsogluteal)Gluteus maximusIM
Volume per siteUp to 3 mlNeedle1.5 in
- Picture a cross dividing one buttock into four quarters.
- The traditional site is the upper outer quarter, close to the hip crest.
- The hip (ventrogluteal) site reaches the same gluteal muscles with landmarks that are easier to trust.
Why it is used. Still shown in many older guides because the muscle is so large.
Careful. The sciatic nerve and the superior gluteal artery are close by, and the fat layer is often thick enough that oil ends up in fat instead of muscle.

Route for Sustanon 250Into the muscle (IM)
- Pick the big musclesShort esters such as propionate and acetate are the oils most often described as stinging or leaving the muscle sore. The hip and outer thigh handle them best; the shoulder is for small volumes only.
- Rotate widelyShort esters leave the body quickly, so they are injected more often. More injections means more spots in the rotation, so each one fully settles first.
- Warm it in your handRolling the vial between your palms for a minute thins the oil so it pushes more easily. Never heat it in water or a microwave.
- Wash your hands
- Alcohol on the stopper and skin, let it dry
- New sterile needle and syringe every time
- Never share any of it
- Sharps into a puncture-proof container

07Risks
Side effects and risks
Sustanon carries the same risks as any testosterone. They grow with dose and with how long you use it.
Shutdown and fertility
Outside testosterone stops your brain from signalling the testes. Natural production and sperm counts fall, and the testes shrink. Because of the decanoate ester, Sustanon takes longer to clear than single-ester testosterone, so recovery starts later.
Red blood cells
Testosterone raises hematocrit. Too high, and the blood thickens, raising the risk of clots and stroke. A CBC partway through tells you where you stand.
Heart and blood pressure
Higher blood pressure, lower HDL cholesterol and fluid retention are common at doses above replacement. Check your blood pressure weekly.
Estrogen effects
Some testosterone becomes estradiol, which can cause bloating, tender nipples and gynecomastia (breast tissue growth) that may not reverse on its own.
Skin, hair and mood
Acne, oily skin, scalp hair loss in men prone to it, irritability and worse sleep apnea. The fast propionate ester can also make injections sting more.
Don’t use it if you
Are under 18, pregnant or breastfeeding, have or have had prostate or breast cancer, untreated sleep apnea, a high red blood cell count, or serious heart, liver or kidney disease. In women, testosterone causes virilization, some of it permanent.
08Interactions
Interactions
Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.
- SeriousWarfarin and other blood thinners
Androgens make warfarin work harder. INR can rise quickly and bleeding has been reported, so the blood thinner usually needs closer checks and often a lower dose.
- CautionInsulin and diabetes tablets
Anabolic steroids can lower blood sugar and change insulin sensitivity, so diabetes medicines may need to be adjusted.
- CautionPrednisone and other corticosteroids
Both hold on to salt and water. Together they make swelling and blood-pressure rises more likely, which matters most with heart, liver or kidney disease.
- Good to knowOral steroids at the same time
An oral 17-alpha-alkylated steroid adds liver strain and pushes HDL cholesterol down further on top of what this injectable already does.
09Bloodwork
Bloodwork checklist
Test before you start, at 6–8 weeks, and 4–6 weeks after your last injection. On long-term TRT, test every 3–6 months.
- Hormones: total and free testosterone, estradiol (sensitive test), LH, FSH
- CBC: hematocrit and hemoglobin
- Lipid panel: HDL, LDL, triglycerides
- Liver panel: ALT, AST
- PSA if you’re over 40
- Blood pressure: weekly at home
10After a course
Post-cycle therapy and support
If you’re ending a course rather than staying on TRT, post-cycle therapy (PCT) with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) is commonly used to help restart natural testosterone. Because the decanoate ester lingers, PCT usually starts about three weeks after the last Sustanon injection, later than with enanthate or cypionate.
An aromatase inhibitor such as anastrozole (Arimidex) is only worth using if bloodwork shows high estradiol with symptoms. You’ll find these options under Pairs well with below.

13Questions
Common questions
Is Sustanon better than testosterone enanthate?
Not better, just different. Milligram for milligram, both deliver testosterone. Sustanon starts faster and lasts longer but gives less even levels; enanthate is simpler to dose steadily. Many people find a single ester easier to manage with bloodwork.
Why does Sustanon have four esters?
It was designed so one injection could cover about three weeks: the fast esters work early and the slow decanoate carries the tail. That made it convenient for TRT with infrequent clinic visits.
How often should I inject Sustanon?
The clinical label uses every three weeks. For steadier levels, many people inject smaller amounts every 3–4 days or twice a week.
Why does Sustanon sting?
The short propionate ester is known for causing more soreness after injection than longer esters. Injecting slowly into a large muscle and rotating sites helps.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is Sustanon legal in Canada?
Testosterone and other anabolic steroids are Schedule IV substances under the Controlled Drugs and Substances Act. Possessing them for personal use isn’t an offence; trafficking, importing and exporting without authorization are.
How is my order packaged?
In a plain, unbranded box with no product names on the outside.
