01The basics
What Zionova Masteron Propionate is
Masteron Propionate is drostanolone propionate, a DHT-derived injectable steroid, at 100 mg per ml in a 10 ml vial (1,000 mg in total). The propionate ester is short, so it acts quickly and is usually injected every other day.
Drostanolone propionate was the form originally prescribed, under names such as Masteron and Drolban, for advanced breast cancer. Today it’s used for cutting: it doesn’t convert to estrogen, so it adds hardness without water. It’s also strongly androgenic. Here’s the full 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
Drostanolone is DHT with a small change that stops it breaking down too quickly in muscle. It supports muscle retention and strength in a calorie deficit.
- No aromatization: it can’t become estrogen, so no estrogenic bloat or gynecomastia from the drug itself.
- Short ester: a half-life of about 2 days, so injections every 2–3 days keep levels steady, and it clears within days of stopping.
- Androgenic: like DHT, it can accelerate hair loss and acne in people prone to them.
04Half-life
Half-life, in plain numbers
A half-life of about 2 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 days
- About 97% gone
- 10 days
- Levels level out with regular use after
- 8 days–10 days
A textbook model built from the half-life alone. Real numbers vary from person to person.
05Clinical reference
Dosing information
Clinical reference. When drostanolone propionate was prescribed for advanced breast cancer, the dose was 100 mg injected three times a week. It was withdrawn and has no current medical use.
At 100 mg per ml, 1 ml is 100 mg and 0.5 ml is 50 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
Masteron Propionate 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 Masteron PropionateInto 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

Side effects and risks
Masteron is milder than many steroids in some ways, but its androgenic effects are real.
Hair loss
If you’re genetically prone to male-pattern baldness, drostanolone can speed it up.
Acne and oily skin
Especially on the back and shoulders. Frequent injections can also irritate injection sites.
Cholesterol
HDL falls and LDL may rise. In a stack, the effects add up.
Suppression
Natural testosterone shuts down. Used without testosterone, low libido and mood are common.
Injection frequency
Every-other-day injections mean more needles. Use new sterile equipment every time and rotate sites.
Don’t use it if you
Are under 18, pregnant or breastfeeding, a woman concerned about virilization, have prostate or breast cancer, heart 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, after 4 weeks, and 3–4 weeks after you finish.
- Lipid panel
- Hormones: testosterone, estradiol, LH, FSH
- CBC
- Liver panel
- PSA if you’re over 40
12After a course
Post-cycle therapy and support
Masteron Propionate clears within a few days, so post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) can start soon after the last injection, unless a longer-acting testosterone is still active. It doesn’t aromatize, so an aromatase inhibitor isn’t needed for it. See Pairs well with below.

15Questions
Common questions
Propionate or enanthate Masteron?
The hormone is the same. Propionate is fast-acting and clears in days but needs injections every 2–3 days; enanthate lasts about 5 days and needs fewer injections.
Is Masteron a fat burner?
Not directly. It helps hold on to muscle and gives a harder look when body fat is already low, which is why it’s popular at the end of a diet.
How does it compare to Masteron Propionate by Genetix Pharma?
Same compound and strength (100 mg/ml, 10 ml). The difference is the manufacturer; compare both under Compare brands on this page.
How fast is shipping in Canada?
Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.
Is Masteron legal in Canada?
Drostanolone 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.
