Overview

Nandrolone decanoate, sold historically as Deca-Durabolin, is nandrolone with a long decanoate ester that releases it over one to two weeks. It was prescribed for anemia, wasting and osteoporosis.

How it works

Nandrolone binds the androgen receptor strongly in muscle but is converted in skin and prostate to a weaker androgen, so it is less androgenic there than testosterone. It also acts on progesterone receptors and strongly suppresses natural testosterone.

Chemistry

From PubChem, the US National Library of Medicine’s chemistry database.

Nandrolone decanoate

Formula: C₂₈H₄₄O₃
Molecular weight: 428.6 g/mol
CAS: 360-70-3
PubChem CID: 9677 ↗

Clinical reference

Older labels used 100 to 200 mg once a week in men and 50 to 100 mg a week in women for anemia of kidney disease, with treatment reviewed every few months.

Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Injection sites

Deca is an oil for intramuscular (IM) injection: deep into a large muscle, never under the skin or into a vein. Our injectables are made in MCT oil, which is thinner than the seed oils many labs use, so it draws and flows through a 25G needle more easily.

Volume per site: Up to 3 ml
Needle: 25 to 38 mm, 22 to 25G

Finding it. Place the heel of your hand on the bony bump at the top of the outer thigh, point your index finger at the front hip bone and spread your middle finger back along the hip crest. Inject in the centre of the V between the two fingers.

Why it is used. Current nursing guidance favours it for adults: a thick muscle under a thin, predictable fat layer, with no large nerves or vessels in the target area.

Watch out. The landmarks take practice; use a mirror or a helper the first few times.

Why these sites for Deca

Intramuscular (IM)

Three common sites. Long-ester oils are usually smooth, so the ventrogluteal, outer thigh and deltoid all work; the deltoid only for small volumes.
Rotate. Reusing a spot before it settles causes lumps and scar tissue. Rotate between at least four spots.
Warm the vial in your hands. Rolling the vial for a minute brings the oil to body temperature so it flows easily. Never heat it in water or a microwave.

Every time: wash your hands, wipe the vial stopper and skin with alcohol, use a new sterile needle and syringe, and never share. See a doctor for spreading redness, heat, swelling, pus, fever or numbness. This is general guidance from standard nursing practice, not medical advice; a pharmacist or nurse can show you in person.

Combinations and interactions

Prescribed or used alongside

Testosterone is normally present alongside, because nandrolone lowers the body’s own testosterone and low testosterone causes low libido and mood.

Drug interactions

Anticoagulants: monitor INR.
Diabetes medicines: monitor blood sugar.

Risks and bloodwork

Sexual function

Low libido and erectile problems are commonly reported, linked to suppressed testosterone and prolactin.

Long suppression

The decanoate ester and nandrolone metabolites keep suppressing natural production for a long time.

Cholesterol and blood pressure

Lower HDL and higher blood pressure.

Detection time

Nandrolone metabolites stay detectable in urine for many months.

Bloodwork doctors check

Complete blood count (hematocrit and hemoglobin)
Lipid panel (HDL, LDL, triglycerides)
Liver enzymes (ALT, AST)
Total and free testosterone, estradiol
LH and FSH
PSA for men over 40
Blood pressure

Not for

People under 18, anyone pregnant or breastfeeding, and anyone with prostate or breast cancer, heart disease, uncontrolled blood pressure, a high red blood cell count, untreated sleep apnea, or liver or kidney disease.

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 an offence under the Act; selling, importing or exporting one without authorisation is. Sports bodies that follow the World Anti-Doping Code ban them in and out of competition. This is general information, not legal advice.
