Overview

Drostanolone enanthate is the slower-releasing version of Masteron. The enanthate ester spreads release of drostanolone over roughly a week.

This listing is Genetix Pharma Masteron Enanthate 200mg/ml (200 mg/ml · 10 ml vial), photographed as we ship it and priced in Canadian dollars.

How it works

Released drostanolone acts at androgen receptors, does not aromatise and has mild anti-estrogenic activity. It suppresses natural testosterone production.

Clinical reference

Only the propionate form was ever approved for people (breast cancer, historically 100 mg three times a week). The enanthate form has no approved human labelling.

Reference information from product labels and clinical literature only. It is not a recommendation or dosing advice for you; any use should be set and monitored by a doctor.

Measuring calculator

Type the amount from your prescription or clinician; the calculator only converts it. It does not suggest how much to take.

Volume to draw–

Injections per vial–

Label strength: 200 mg/ml in a 10 ml vial.

Combinations and interactions

  • Same hormone as drostanolone propionate, with fewer injections.
  • Adds to hair-loss and lipid effects of other androgens.
  • Interactions: not formally studied; warfarin users should be monitored.

Risks and side effects

  • Hair and skin. Accelerated pattern hair loss and acne.
  • Cholesterol. Lower HDL.
  • Suppression. Reduced natural testosterone and sperm.

Do not use it if you are under 18, pregnant, or have prostate disease or severe hair loss.

Bloodwork to discuss with your doctor

  • Lipid panel
  • Testosterone
  • Hematocrit

Injection sites

Masteron Enanthate 200mg/ml is an oil made for deep intramuscular injection. Our injectables use MCT oil, which is thinner than cottonseed or grapeseed oil and passes more easily through a 25G needle. These are the standard nursing sites, with what to look for at each.

1VentroglutealSide of the hip · Gluteus mediusIM

Finding it. Place the heel of your opposite hand on the bony bump at the top of the thigh, point your index finger at the front hip bone and fan your middle finger back along the hip crest. The target is the centre of that V.

Why it is used. Thick muscle with a thin fat layer and no major nerves or vessels in the target zone. Nursing references now rank it first for adults.

Watch for. Finding the landmarks on yourself takes practice; a mirror or a helper makes the first few easier.

Nursing reference volume: Up to 3 ml

2Vastus lateralisOuter thigh · QuadricepsIM

Finding it. Divide the thigh from hip to knee into thirds and use the middle third on the outer front surface.

Why it is used. Easy to see and reach while seated, with plenty of muscle.

Watch for. Keep to the outer side: the femoral nerve and vessels run along the inner thigh. Soreness when walking for a day is common.

Nursing reference volume: Up to 3 ml

3DeltoidShoulder · DeltoidIM

Finding it. Locate the bony point of the shoulder and move two to three finger widths down to the thickest part of the muscle on the outside of the arm.

Why it is used. Quick to reach and good for small volumes.

Watch for. It is a small muscle. Stay high: the axillary and radial nerves lie lower on the arm.

Nursing reference volume: Up to 1 ml

!DorsoglutealUpper outer buttock · Gluteus maximusIM

Finding it. The traditional upper outer quarter of the buttock.

Why it is used. A large, familiar muscle still shown in older guides.

Watch for. The sciatic nerve and a major artery are nearby and the fat layer is thicker. Most current guidance prefers the ventrogluteal site.

Nursing reference volume: Up to 3 ml

Every time: wash your hands, swab the stopper and skin with alcohol, use a new sterile needle and syringe and never share. See a doctor for spreading redness, heat, swelling, fever or numbness. This is general reference information from standard injection guidance, not medical advice.

Storage and handling

Keep the vial at room temperature (15 to 25 °C), out of direct light. Do not refrigerate or freeze it: cold can make the hormone crystallise. Wipe the rubber stopper with alcohol before each draw and use a fresh needle every time.

Anabolic steroids are listed in Schedule IV of the Controlled Drugs and Substances Act. Simple possession of a Schedule IV substance is not itself an offence, but importing, exporting, producing or selling one without authorisation is. Anabolic agents are prohibited in tested sport. Laws change, so check the current rules for your situation.

FAQ

How long does it last?

About a week per injection.

Is it stronger than propionate?

The hormone is the same; only the release speed changes.

Does it cause water retention?

It cannot form estradiol, so estrogen-related fluid retention is uncommon.

How fast will it reach me?

Ha, Masteron's mild anti-estrogen effect is a nice bonus. Thanks, Brian! Bloodwork still tells you where estradiol actually sits.
