Overview

Testosterone propionate carries a short three-carbon ester, so it is absorbed and cleared within a few days. It was the first injectable testosterone ester used in medicine, but its short life means frequent injections.

How it works

It acts like any testosterone once the ester is cleaved: androgen-receptor activation, red blood cell stimulation, partial conversion to estradiol and DHT and suppression of LH and FSH. Levels rise and fall faster than with longer esters.

Chemistry

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

Clinical reference

Modern testosterone therapy no longer uses propionate because of how often it must be injected. Older prescribing information listed 25 to 50 mg two or three times a week.

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

Testosterone Propionate 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 Testosterone Propionate

Intramuscular (IM)

Largest muscles first. Short esters and high-strength blends are the oils most often reported to sting. The ventrogluteal and outer thigh handle them best; keep the deltoid for small volumes.
Rotate widely. Short esters are injected more often, so spread injections across more sites, left and right.
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

Longer esters such as enanthate or cypionate do the same job with fewer injections.
hCG is the usual clinical partner when fertility is a concern.

Drug interactions

Anticoagulants: INR may rise.
Diabetes medicines: possible drop in blood sugar.

Risks and bloodwork

Injection-site soreness

Short esters are known for sore, warm injection sites in the days after.

Shutdown

Natural testosterone and sperm production stop while it is used.

Blood and heart

Hematocrit, blood pressure and cholesterol changes, as with other testosterone forms.

Androgenic effects

Acne, oily skin and hair loss in prone men.

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.

FAQ

Why choose propionate over enanthate?

Levels fall quickly after stopping, which some prefer, but it needs injections every two or three days.

Is it painful to inject?

It is more likely to cause post-injection soreness than longer esters.

How long does it stay active?

Its half-life is about one day, so blood levels drop within a few days of the last injection.

How fast will it arrive?

Orders ship from Vancouver by Canada Post Xpresspost. You get a tracking number within 72 hours of payment; delivery then takes 1 to 2 business days in BC, 3 to 4 in Ontario and 3 to 5 in Quebec.
