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.
These are reference amounts from labels and clinical studies, not a personal recommendation. A doctor sets the right dose for you, using your bloodwork.

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.
- Muscle
- Gluteus medius and minimus
- Group
- Glutes · hip abductors
- Volume (nursing reference)
- Up to 3 ml per site
- Needle
- 25–38 mm (1–1.5 in), 22–25G
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.
- Muscle
- Vastus lateralis
- Group
- Quadriceps · front of thigh
- Volume (nursing reference)
- Up to 3 ml per site
- Needle
- 25–38 mm (1–1.5 in), 22–25G
Finding it. Split the thigh between the hip and the knee into thirds; use the middle third, on the outer side of the front of the thigh.
Why people choose it. The easiest large muscle to reach and see when injecting yourself, seated, with good muscle bulk and well away from the major nerves and vessels.
Watch out. Stay on the outer side: the femoral nerve, artery and vein run along the inner front of the thigh. Some people feel it when walking for a day or two.
- Muscle
- Deltoid
- Group
- Shoulder
- Volume (nursing reference)
- Up to 1 ml per site
- Needle
- 25 mm (1 in), 23–25G
Finding it. Find the bony tip of the shoulder (acromion); the site is the thickest part of the muscle about 2.5–5 cm (2–3 finger widths) below it, centred on the side of the arm.
Why people choose it. Quick to reach and easy to expose, which is why vaccines go here. Good for small volumes.
Watch out. A small muscle: larger volumes hurt and can leak back. The axillary and radial nerves run below the safe zone, so do not go low on the arm.
- Muscle
- Gluteus maximus
- Group
- Glutes · buttock
- Volume (nursing reference)
- Up to 3 ml per site
- Needle
- 38 mm (1.5 in)
Finding it. The traditional "upper outer quarter of the buttock".
Why people choose it. Large muscle and familiar, so many older guides still show it.
Watch out. Most nursing guidance has moved away from it: the sciatic nerve and superior gluteal artery are close by, and the fat layer is thicker, so the oil may not reach the muscle. The ventrogluteal site gives the same glute muscle mass with less risk.
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.
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.
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.
