Overview

Testosterone 400 packs 400 mg of testosterone esters into each millilitre, mainly enanthate and cypionate. The higher concentration means a smaller injection volume for the same amount of hormone.

This listing is Zionova Testosterone 400 (400 mg/ml · 10 ml vial), photographed as we ship it and priced in Canadian dollars.

How it works

The enanthate and cypionate esters release over several days each. Once freed, the testosterone behaves like the body’s own: androgen-receptor activation in muscle and bone, more red blood cells, partial conversion to estradiol and DHT, and suppression of LH and FSH.

Clinical reference

No prescription product is sold at 400 mg/ml. For comparison, approved enanthate and cypionate products list 50 to 400 mg every two to four weeks for hypogonadism, which this concentration would cover in one millilitre or less.

Label strength: 400 mg/ml in a 10 ml vial.

Combinations and interactions

Equivalent in effect to the single-ester enanthate or cypionate vials; only the concentration differs.
Higher concentrations often contain more benzyl benzoate or alcohol to keep the hormone dissolved, which some people find stings.
Interactions are those of testosterone: warfarin, diabetes medication, corticosteroids.

Risks and side effects

Measuring errors. At 400 mg per ml, a small misreading of the syringe means a large change in dose. Use the measuring calculator on this page.
Post-injection irritation. Concentrated oils can sting or cause local swelling.
Usual testosterone risks. Suppressed fertility, raised hematocrit, lower HDL and estrogen-related side effects.

Do not use it if you are under 18, pregnant, have hormone-sensitive cancer, a high hematocrit or serious heart, liver or kidney disease.

Injection sites

Testosterone 400 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

Is 400 mg/ml stronger than 250 mg/ml?

Each millilitre contains more hormone, so the same volume delivers more. The hormone itself is the same.

Why can it feel warm after injecting?

Concentrated blends use more solvent to stay liquid, which can cause brief warmth or stinging.

Which esters are in the Zionova and Genetix versions?

Both are labelled as enanthate-based blends; Genetix T400 states enanthate and cypionate on the vial.
