About Genetix Deca-Durabolin

Nandrolone decanoate (Deca-Durabolin) is a long-acting steroid that was prescribed for anemia from kidney failure and for muscle wasting. It is known for joint comfort and slow, steady gains.

Commonly used for

  • Muscle and weight gain
  • Historically: anemia of kidney failure and wasting conditions
  • People looking for a long-acting compound

How it works

Nandrolone binds androgen receptors and boosts red blood cell production. It converts only slightly to estrogen but acts on progesterone receptors, and it suppresses natural testosterone strongly and for a long time.

Half-life: about 6-12 days.

Release profile

How levels rise and fall after a single dose, based on a half-life of about 6-12 days. Each mark on the axis is one half-life; after about five, almost none is left.

An illustration from the half-life only; real levels vary with dose, injection site and the person.

Clinical reference dose

Clinical reference: older prescribing labels used 100–200 mg once a week for men and 50–100 mg a week for women with anemia of kidney disease, with treatment reviewed every few months.

100 mg0.5 ml

At 200 mg per ml. Measure oil with a 1 ml or 3 ml syringe marked in 0.1 ml steps.

Nandrolone can be detected in drug tests for many months after the last dose.

Injection sites

Deca-Durabolin is an oil-based injection made for intramuscular (IM) use: deep into a large muscle, not under the skin and never into a vein. Like every injectable we sell, it is made in MCT oil (medium-chain triglycerides), a lighter, thinner oil than the grapeseed or cottonseed oil many labs use, so it draws up and pushes through a 25G needle more easily.

Finding it. Put the heel of your hand on the bony point at the top of the outer thigh (greater trochanter), index finger on the front hip bone (anterior superior iliac spine) and spread the middle finger back along the hip crest. The injection goes in the middle of the V between those two fingers.

Why people choose it. Nursing guidance now treats this as the preferred deep-muscle site for adults: thick muscle, a thin and predictable fat layer, and no major nerves or blood vessels in the target zone.

Watch out. Takes practice to find the landmarks on yourself; use a mirror or have someone help the first few times.

Why these sites for Deca-Durabolin

Intramuscular (IM)
  • All three sites work. Long-ester oils like this one are usually smooth on the muscle, so the ventrogluteal, outer thigh and deltoid are all commonly used. The deltoid suits smaller volumes only.
  • Rotate left and right. Using the same spot again before it has settled causes lumps and scar tissue. Most people rotate between at least four spots (both hips, both thighs).
  • Warm MCT oil flows best. Rolling the vial between your hands for a minute brings the oil to body temperature so it pushes more smoothly. Never heat it in water or a microwave.

Every time: wash your hands, wipe the vial top and the skin with alcohol and let it dry, use a new sterile needle and syringe, and never share. Get medical help for spreading redness, heat, swelling, pus, fever, numbness or pain that keeps getting worse. This is general reference information from standard nursing injection guidance, not medical advice; a pharmacist or nurse can show you the technique in person.

Combinations and interactions

Often compared or used with

  • Usually used with testosterone, because nandrolone alone switches off natural testosterone and can cause low libido and erection problems.
  • Compared with NPP, the same hormone with a short ester that clears faster.
  • Prolactin can rise; doctors check it before reaching for any treatment.

Interactions to know

  • Warfarin: INR can rise.
  • Diabetes medicines: blood sugar may fall.

Tell your doctor and pharmacist about everything you take, including supplements, before adding anything new.

Side effects and risks

Long shutdown

Natural testosterone can take many months to recover after decanoate.

Sexual side effects

Low libido and erection problems (“Deca dick”) when testosterone is low relative to nandrolone.

Progesterone-type effects

Water retention and gynecomastia.

Lipids and blood

Lower HDL, higher hematocrit.

Injection safety

Use a new sterile needle and syringe every time, wipe the stopper and skin with alcohol, and never share. Redness, heat or swelling that gets worse after a day or two can mean infection and needs a doctor.

Don’t use it if you

Are under 18, pregnant or breastfeeding, have prostate or breast cancer, heart or kidney disease, or need to pass drug tests.

Bloodwork checklist

  • Complete blood count (hematocrit, hemoglobin)
  • Lipid panel (HDL, LDL, triglycerides)
  • Liver enzymes (ALT, AST)
  • Kidney function (creatinine, eGFR)
  • Testosterone, sensitive estradiol, LH and FSH
  • PSA if you are over 40
  • Blood pressure at home, weekly

Your family doctor can order these, or you can pay for private testing at labs such as LifeLabs or Dynacare. Test before you start, after 6–8 weeks, and again after you stop.

Common questions

Why is it injected weekly?

The decanoate ester has a half-life of about 6–12 days.

Does it help joints?

Many users report less joint pain, possibly from fluid retention and collagen effects, but the evidence is limited.

How fast does it ship?

Orders ship from inside Canada with a tracking number within 72 hours of payment. Weekend orders are packed on Sunday or Monday. Canada Post Xpresspost takes 2–5 business days to most cities; UPS or FedEx is faster. Shipping is free by Canada Post over $300 and by UPS or FedEx over $1,000.

How is it packaged?

In a plain box with no product names or branding on the outside.

Is nandrolone decanoate legal in Canada?

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.
