01The basics
What NPP by Genetix Pharma is
NPP is nandrolone phenylpropionate: the same hormone as Deca, on a much shorter ester. Genetix Pharma’s version is 100 mg per ml in a 10 ml vial (1,000 mg in total). It was sold for decades under the brand name Durabolin.
The short ester means NPP starts working within days and clears within days, giving more control than Deca at the cost of more frequent injections. The risks are those of nandrolone: deep suppression, prolactin-related side effects and libido problems without enough testosterone.
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 strongly anabolic with milder androgenic effects than testosterone, because it converts to the weaker DHN rather than DHT.
- Short ester: phenylpropionate gives a half-life of about 2–3 days, so it’s injected every 2–3 days.
- Progestin activity can raise prolactin, which is behind some of its sexual side effects.
04Half-life
Half-life, in plain numbers
A half-life of about 2-3 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
- 2.5 days
- About 97% gone
- 12.5 days
- Levels level out with regular use after
- 10 days–12.5 days
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. Nandrolone phenylpropionate was prescribed for conditions such as osteoporosis and anemia at modest doses, usually injected weekly. It’s no longer marketed in North America, and current nandrolone labeling refers to the decanoate form (100–200 mg a week for men with anemia of kidney disease).
At 100 mg per ml, 0.5 ml is 50 mg and 1 ml is 100 mg. Every risk on this page rises with dose. Talk to a doctor before use.

07Injection sites
Where it is injected
Npp 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
Volume per siteUp to 3 mlNeedle1–1.5 in, 22–25G
- 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
Volume per siteUp to 3 mlNeedle1–1.5 in, 22–25G
- 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
Volume per siteUp to 1 mlNeedle1 in, 23–25G
- 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
Volume per siteUp to 3 mlNeedle1.5 in
- 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 NppInto the muscle (IM)
- Pick the big musclesShort esters such as propionate and acetate are the oils most often described as stinging or leaving the muscle sore. The hip and outer thigh handle them best; the shoulder is for small volumes only.
- Rotate widelyShort esters leave the body quickly, so they are injected more often. More injections means more spots in the rotation, so each one fully settles first.
- 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

08Risks
Side effects and risks
NPP’s side effects match Deca’s; they just come and go faster.
Libido and prolactin
Low libido and erectile problems are common when testosterone is too low alongside it or prolactin rises.
Suppression
Natural testosterone shuts down strongly.
Heart and blood pressure
Lower HDL, higher blood pressure and some water retention.
Injection frequency
Injections every 2–3 days raise the chance of irritation and infection; use sterile equipment every time.
Gynecomastia
Possible through prolactin and progesterone receptor effects.
Don’t use it if you
Are under 18, pregnant or breastfeeding, trying to conceive, have prostate or breast cancer, heart disease or high blood pressure.
09Interactions
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.
10Bloodwork
Bloodwork checklist
Test before you start, at 4–6 weeks, and 3–4 weeks after you stop.
- Prolactin
- Testosterone, estradiol, LH, FSH
- CBC and lipids
- Blood pressure weekly
11After a course
Post-cycle therapy and support
NPP clears within days, so post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) can begin a few days after the last injection, unless a longer-acting testosterone is also in use. See Pairs well with below.

14Questions
Common questions
NPP or Deca?
The same hormone. NPP works and clears faster and needs injections every 2–3 days; Deca is injected weekly but lingers for weeks.
Does NPP cause less water retention than Deca?
Many users report so, mainly because frequent small doses avoid big peaks. The hormone itself is the same.
Does NPP hurt to inject?
Short esters can cause more soreness than long ones. Injecting slowly and rotating sites helps.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is NPP 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.
