Overview

Testosterone enanthate is plain testosterone bound to a seven-carbon ester. The ester holds the hormone in the oil depot after an intramuscular injection and releases it over several days, which is why enanthate has been a mainstay of hormone replacement for decades.

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

How it works

Once enzymes in the blood strip the ester, the body handles it like its own testosterone. It switches on androgen receptors in muscle, bone, skin and the brain, lifts red-cell production in the bone marrow, and is partly converted into estradiol by aromatase and into DHT by 5-alpha reductase. Because the brain senses the outside supply, it lowers LH and FSH, and the testes slow both hormone and sperm production.

Clinical reference

Prescribing information for testosterone enanthate in men with confirmed hypogonadism lists 50 to 400 mg every two to four weeks. Endocrine Society guidance favours steadier dosing in the range of 75 to 100 mg each week, adjusted to blood levels drawn halfway between injections.

Combinations and interactions

Often compared with testosterone cypionate; the two are dosed the same way in clinical practice and differ only slightly in release.
Doctors sometimes add HCG to replacement therapy to keep testicular volume and fertility.
An aromatase inhibitor is only considered when bloodwork shows high estradiol with symptoms; driving estrogen too low causes its own problems.
Interactions: testosterone can strengthen the effect of warfarin and lower blood sugar in people using insulin or diabetes tablets.

Risks and side effects

Natural production stops. Your own testosterone and sperm output fall while an outside supply is present; recovery after stopping can take months.
Thicker blood. Hematocrit rises. Very high values increase the chance of clots and stroke.
Cholesterol and blood pressure. HDL tends to drop and blood pressure can climb, more so at higher amounts.
Estrogen side effects. Fluid retention and breast tissue growth (gynecomastia) when estradiol runs high.
Skin and scalp. Oily skin, acne and faster pattern hair loss in men who are prone to it.

Do not use it if you are under 18, a woman who is or may become pregnant, have prostate or male breast cancer, a hematocrit already above the normal range, untreated sleep apnea, or serious heart, liver or kidney disease.

Injection sites

Testosterone Enanthate 250mg/ml 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 long does one injection stay active?

The half-life after an intramuscular injection is roughly four to five days, so blood levels peak within a couple of days and taper over the following week.

Is enanthate stronger than cypionate?

No. Milligram for milligram they deliver almost the same amount of testosterone; cypionate is just a little slower to release.

Why does the oil look cloudy after shipping in winter?

Cold can make testosterone crystallise. Warm the sealed vial in your hand or warm water and roll it until the oil is clear again.

How fast will it reach me?

Orders leave Vancouver by Canada Post Xpresspost and the tracking number arrives within 72 hours of your e-Transfer. Most provinces receive parcels 1 to 6 business days after that; the territories can take up to 10. Xpresspost is free on orders over $300, and a lost or seized parcel is reshipped at no charge.
