Overview

Sustanon 250 combines four testosterone esters in one millilitre: propionate (30 mg), phenylpropionate (60 mg), isocaproate (60 mg) and decanoate (100 mg). Mixing fast and slow esters was meant to give a quick start and a long tail from a single injection.

This listing is Zionova Sustanon 250 (250 mg/ml · 10 ml vial), photographed as we ship it and priced in Canadian dollars.

How it works

Each ester releases at its own pace, from about a day for propionate to two weeks or more for decanoate. Once freed, every ester becomes ordinary testosterone and acts on androgen receptors, red-cell production and the hormonal feedback loop like any other testosterone.

Clinical reference

Sustanon 250 is approved in Canada for testosterone replacement. Its product monograph suggests 1 ml (250 mg) every three weeks, adjusted by the prescriber to symptoms and blood levels.

Combinations and interactions

Compared with single esters such as cypionate, Sustanon gives a less even curve between injections despite its long tail.
HCG may be prescribed alongside to keep testicular function.
Interactions: warfarin, insulin and oral diabetes drugs, and corticosteroids, as with other testosterone.

Risks and side effects

Peaks and dips. The fast esters create an early peak; some people notice mood or energy swings across the three-week interval.
Fertility. Sperm production falls during use.
Hematocrit and lipids. Thicker blood and lower HDL are the most common lab changes.
Peanut oil carrier. Branded Sustanon uses arachis oil; check the label of the vial you receive if you have a nut allergy.

Do not use it if you are under 18, pregnant, allergic to any oil or ingredient on the label, or have prostate or breast cancer, polycythemia or serious heart disease.

Injection sites

Sustanon 250 is an oil made for deep intramuscular injection. Our injectables use MCT oil, which is thinner than cottonseed or grapeseed oil and passes more easily through a 25G needle. These are the standard nursing sites, with what to look for at each.

1VentroglutealSide of the hip · Gluteus mediusIM

Finding it. Place the heel of your opposite hand on the bony bump at the top of the thigh, point your index finger at the front hip bone and fan your middle finger back along the hip crest. The target is the centre of that V.

Why it is used. Thick muscle with a thin fat layer and no major nerves or vessels in the target zone. Nursing references now rank it first for adults.

Watch for. Finding the landmarks on yourself takes practice; a mirror or a helper makes the first few easier.

Nursing reference volume: Up to 3 ml

2Vastus lateralisOuter thigh · QuadricepsIM

Finding it. Divide the thigh from hip to knee into thirds and use the middle third on the outer front surface.

Why it is used. Easy to see and reach while seated, with plenty of muscle.

Watch for. Keep to the outer side: the femoral nerve and vessels run along the inner thigh. Soreness when walking for a day is common.

Nursing reference volume: Up to 3 ml

3DeltoidShoulder · DeltoidIM

Finding it. Locate the bony point of the shoulder and move two to three finger widths down to the thickest part of the muscle on the outside of the arm.

Why it is used. Quick to reach and good for small volumes.

Watch for. It is a small muscle. Stay high: the axillary and radial nerves lie lower on the arm.

Nursing reference volume: Up to 1 ml

!DorsoglutealUpper outer buttock · Gluteus maximusIM

Finding it. The traditional upper outer quarter of the buttock.

Why it is used. A large, familiar muscle still shown in older guides.

Watch for. The sciatic nerve and a major artery are nearby and the fat layer is thicker. Most current guidance prefers the ventrogluteal site.

Nursing reference volume: Up to 3 ml

Every time: wash your hands, swab the stopper and skin with alcohol, use a new sterile needle and syringe and never share. See a doctor for spreading redness, heat, swelling, fever or numbness. This is general reference information from standard injection guidance, not medical advice.

Storage and handling

Keep the vial at room temperature (15 to 25 °C), out of direct light. Do not refrigerate or freeze it: cold can make the hormone crystallise. Wipe the rubber stopper with alcohol before each draw and use a fresh needle every time.

Canadian legal status

Anabolic steroids are listed in Schedule IV of the Controlled Drugs and Substances Act. Simple possession of a Schedule IV substance is not itself an offence, but importing, exporting, producing or selling one without authorisation is. Anabolic agents are prohibited in tested sport. Laws change, so check the current rules for your situation.

FAQ

How much testosterone is in each millilitre?

250 mg of testosterone esters, equal to about 176 mg of testosterone itself once the esters are removed.

Why four esters?

The blend was designed so a single injection would act quickly and keep working for weeks.

Does Sustanon need more frequent injections than the label suggests?

Many prescribers shorten the interval to two weeks to smooth levels. That decision belongs with your doctor.
