01The basics
What Deca Durabolin by Genetix Pharma is
This is nandrolone decanoate from Genetix Pharma, 200 mg per ml in a 10 ml vial (2,000 mg in total). Nandrolone decanoate has a long medical history, from treating anemia in kidney disease to muscle wasting, and it remains one of the most widely used bulking steroids.
It builds size steadily with fewer androgenic side effects than testosterone. Its well-known downsides are deep, long-lasting suppression and libido problems when it’s used without enough testosterone. Here’s the practical picture.
02Molecule
The molecule
What is actually in the vial or tablet, from the public chemistry databases of the U.S. National Library of Medicine.

03How it works
How it works
Nandrolone is a close relative of testosterone, missing one carbon atom.
- Anabolic with milder androgen effects: in the scalp and prostate it becomes the weaker DHN, not DHT.
- Progestin activity: it acts on progesterone receptors and can raise prolactin.
- Very long-acting: the decanoate ester gives a half-life of about 6–12 days, so it builds slowly and lingers for weeks.
04Half-life
Half-life, in plain numbers
A half-life of about 6-12 days means half of what is in the body is gone after that time, then half of the rest, and so on. The ester decides how slowly the hormone leaves the injection depot, which is why long esters are injected less often than short ones.
- One half-life
- 9 days
- About 97% gone
- 45 days
- Levels level out with regular use after
- 36 days–45 days
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. For anemia of kidney disease, labeled adult doses were 100–200 mg a week for men and 50–100 mg a week for women.
At 200 mg per ml, 0.5 ml is 100 mg. Every risk on this page rises with dose. Talk to a doctor before use, and get bloodwork before, during and after.

07Injection sites
Where it is injected
Deca Durabolin is an oil, so it goes deep into a large muscle with a regular needle: never just under the skin and never into a vein. These are the muscles standard nursing guidance uses.
1Hip (ventrogluteal)Gluteus medius and minimusIM
- Lie on your side or stand. Put the heel of your hand on the bony knob at the top of the thigh (greater trochanter): left hand on the right hip, right hand on the left.
- Point your index finger at the bony front of the hip (anterior superior iliac spine) and fan your middle finger back along the hip crest to make a V.
- The site is the middle of that V.
Why it is used. Many nursing programs now teach it first. The muscle is thick, the fat over it is thin and fairly even, and no large nerve or vessel crosses the target area.
Careful. The landmarks take a few tries to find on your own body. A mirror or a helper makes the first ones easier.

2Outer thigh (vastus lateralis)Vastus lateralis, quadricepsIM
- Sit down. Find the bony knob at the top of the thigh and the top of the kneecap.
- Divide the distance between them into three equal parts.
- Use the middle part, on the outer front of the thigh, roughly where a trouser seam would run.
Why it is used. The easiest large muscle to see and reach on yourself, with plenty of muscle to work with.
Careful. Stay on the outer side. The femoral artery, vein and nerve run along the inner front of the thigh. It can feel stiff for a day or two.

3Shoulder (deltoid)DeltoidIM
- Find the bony ridge at the top of the shoulder (acromion).
- Measure two to three finger-widths straight down from it.
- Inject into the thickest part of the muscle on the outer side of the arm, well above the armpit line.
Why it is used. Quick to reach and the usual place for vaccines. Good for small volumes.
Careful. A small muscle: larger amounts hurt and can leak back out. Going too low on the arm risks the axillary and radial nerves.

!Upper buttock (dorsogluteal)Gluteus maximusIM
- Picture a cross dividing one buttock into four quarters.
- The traditional site is the upper outer quarter, close to the hip crest.
- The hip (ventrogluteal) site reaches the same gluteal muscles with landmarks that are easier to trust.
Why it is used. Still shown in many older guides because the muscle is so large.
Careful. The sciatic nerve and the superior gluteal artery are close by, and the fat layer is often thick enough that oil ends up in fat instead of muscle.

Route for Deca DurabolinInto the muscle (IM)
- Hip, thigh or shoulderLong-ester oils like this one tend to be smooth on the muscle, so all three common sites are used. Keep the shoulder for smaller volumes.
- Rotate sidesGoing back to the same spot before it has healed builds lumps and scar tissue. Most people rotate through at least four spots: both hips and both thighs.
- Warm it in your handRolling the vial between your palms for a minute thins the oil so it pushes more easily. Never heat it in water or a microwave.
- Wash your hands
- Alcohol on the stopper and skin, let it dry
- New sterile needle and syringe every time
- Never share any of it
- Sharps into a puncture-proof container

Add to cart09Risks
Side effects and risks
Nandrolone is milder than testosterone in some ways and harsher in others.
Sexual side effects
Low libido and erectile problems are common if testosterone runs low alongside it, or if prolactin rises.
Deep suppression
Nandrolone shuts down natural testosterone strongly, and recovery can be slow.
Heart
Lower HDL, higher blood pressure and fluid retention. Long-term misuse is linked to heart muscle changes.
Gynecomastia
Through prolactin and progesterone receptors, as well as some estrogen.
Detection
Nandrolone metabolites can be detected for many months after the last injection.
Don’t use it if you
Are under 18, pregnant or breastfeeding, trying to conceive, have prostate or breast cancer, heart, liver or kidney disease, or high blood pressure.
10Interactions
Interactions
Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.
- SeriousWarfarin and other blood thinners
Androgens make warfarin work harder. INR can rise quickly and bleeding has been reported, so the blood thinner usually needs closer checks and often a lower dose.
- CautionInsulin and diabetes tablets
Anabolic steroids can lower blood sugar and change insulin sensitivity, so diabetes medicines may need to be adjusted.
- CautionPrednisone and other corticosteroids
Both hold on to salt and water. Together they make swelling and blood-pressure rises more likely, which matters most with heart, liver or kidney disease.
- Good to knowOral steroids at the same time
An oral 17-alpha-alkylated steroid adds liver strain and pushes HDL cholesterol down further on top of what this injectable already does.
11Bloodwork
Bloodwork checklist
Test before you start, at 6–8 weeks, and 6–8 weeks after the last injection.
- Prolactin
- Testosterone, estradiol, LH, FSH
- CBC
- Lipids and blood pressure
12After a course
Post-cycle therapy and support
Because nandrolone decanoate clears slowly, post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) usually starts about three weeks after the last injection. See Pairs well with below.

15Questions
Common questions
How does it compare to Zionova Deca?
Same compound and strength (200 mg/ml, 10 ml vial). The difference is the manufacturer and price; compare them under Compare brands on this page.
Deca or NPP?
Same hormone, different esters. NPP (phenylpropionate) acts and clears in days and needs injections every 2–3 days; Deca lasts a week or more.
Why run testosterone with Deca?
Nandrolone shuts down your own testosterone. Without enough testosterone alongside it, libido, erections and mood often suffer.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is Deca legal in Canada?
Nandrolone is an anabolic steroid, listed in Schedule IV of the Controlled Drugs and Substances Act. Possessing it for personal use isn’t an offence; trafficking, importing and exporting without authorization are.
How is my order packaged?
In a plain, unbranded box with no product names on the outside.
