Overview

Nandrolone decanoate, sold for decades as Deca-Durabolin, is a 19-nortestosterone with a ten-carbon ester that releases slowly over one to two weeks. It has a long medical history in anemia and wasting conditions.

This listing is Genetix Pharma Deca Durabolin (200 mg/ml · 10 ml vial), photographed as we ship it and priced in Canadian dollars.

How it works

Nandrolone binds the androgen receptor with a stronger anabolic than androgenic profile, because it is converted to a weaker androgen in skin and prostate tissue. It aromatises less than testosterone but has progestogenic activity, and it suppresses natural testosterone production.

Clinical reference

Historic Deca-Durabolin labelling for anemia of chronic kidney disease used 50 to 100 mg a week in women and 100 to 200 mg a week in men. Trials in HIV-related weight loss used similar weekly amounts.

Reference information from product labels and clinical literature only. It is not a recommendation or dosing advice for you; any use should be set and monitored by a doctor.

Measuring calculator

Type the amount from your prescription or clinician; the calculator only converts it. It does not suggest how much to take.

Combinations and interactions

  • Often compared with NPP, the short-ester form of the same hormone.
  • Because nandrolone lowers natural testosterone, doctors historically paired it with testosterone replacement in men.
  • Interactions: may increase the effect of warfarin; can change insulin needs.

Risks and side effects

  • Long suppression. Natural testosterone can stay low for months after stopping.
  • Sexual function. Low libido and erectile problems are commonly reported when used without testosterone.
  • Prolactin effects. Its progestogenic action can raise prolactin.
  • Joints and fluid. Water retention is common.
  • Heart and blood. Raised hematocrit and lower HDL.

Do not use it if you are under 18, pregnant, have prostate or breast cancer, kidney or heart disease, or are trying to conceive.

Bloodwork to discuss with your doctor

  • Testosterone
  • Prolactin
  • Estradiol
  • Hematocrit
  • Lipid panel

Injection sites

Deca Durabolin 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.

Muscle drawing: OpenStax & Tomáš Kebert, umimeto.org, CC BY-SA 4.0, recoloured.
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.

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

Why is it called a 19-nor steroid?

Nandrolone lacks the carbon atom at position 19 that testosterone has, which changes how it acts in the body.

How long does it stay in the system?

The decanoate ester releases over a week or more, and metabolites can be detected for months.

Is Deca still prescribed?

Rarely. It remains approved in some countries for anemia of kidney disease and osteoporosis.

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.
