About Zionova Primobolan

Methenolone enanthate (Primobolan Depot) is a mild, DHT-derived injectable steroid with a long ester, known for slow gains and few estrogen effects.

Zionova: Each order is one 10 ml vial.

Commonly used for

  • Slow, lean muscle gain
  • People who want to avoid estrogen-related side effects

How it works

It binds androgen receptors, does not convert to estrogen and is less suppressive than most steroids, though it still lowers natural testosterone.

Half-life: about 5 days.

Release profile

How levels rise and fall after a single dose, based on a half-life of about 5 days. Each mark on the axis is one half-life; after about five, almost none is left.

An illustration from the half-life only; real levels vary with dose, injection site and the person.

Clinical reference dose

Clinical reference: where Primobolan Depot was prescribed, labels used about 100 mg every two weeks. It is not approved in Canada.

It is one of the most counterfeited steroids worldwide.

Injection sites

Primobolan is an oil-based injection made for intramuscular (IM) use: deep into a large muscle, not under the skin and never into a vein. Like every injectable we sell, it is made in MCT oil (medium-chain triglycerides), a lighter, thinner oil than the grapeseed or cottonseed oil many labs use, so it draws up and pushes through a 25G needle more easily.

Finding it. Put the heel of your hand on the bony point at the top of the outer thigh (greater trochanter), index finger on the front hip bone (anterior superior iliac spine) and spread the middle finger back along the hip crest. The injection goes in the middle of the V between those two fingers.

Why people choose it. Nursing guidance now treats this as the preferred deep-muscle site for adults: thick muscle, a thin and predictable fat layer, and no major nerves or blood vessels in the target zone.

Watch out. Takes practice to find the landmarks on yourself; use a mirror or have someone help the first few times.

Why these sites for Primobolan

Intramuscular (IM)
  • All three sites work. Long-ester oils like this one are usually smooth on the muscle, so the ventrogluteal, outer thigh and deltoid are all commonly used. The deltoid suits smaller volumes only.
  • Rotate left and right. Using the same spot again before it has settled causes lumps and scar tissue. Most people rotate between at least four spots (both hips, both thighs).
  • Warm MCT oil flows best. Rolling the vial between your hands for a minute brings the oil to body temperature so it pushes more smoothly. Never heat it in water or a microwave.

Every time: wash your hands, wipe the vial top and the skin with alcohol and let it dry, use a new sterile needle and syringe, and never share. Get medical help for spreading redness, heat, swelling, pus, fever, numbness or pain that keeps getting worse. This is general reference information from standard nursing injection guidance, not medical advice; a pharmacist or nurse can show you the technique in person.

Combinations and interactions

Often compared or used with

  • Usually compared with Masteron and low-dose testosterone for lean, slow gains.
  • Often paired with a testosterone base because it still suppresses natural production.

Interactions to know

  • Warfarin: INR can rise.

Tell your doctor and pharmacist about everything you take, including supplements, before adding anything new.

Side effects and risks

Lipids

Lowers HDL, though less than stronger androgens.

Hair loss

DHT-type hair loss in prone men.

Shutdown

Natural testosterone falls.

Injection safety

Use a new sterile needle and syringe every time, wipe the stopper and skin with alcohol, and never share. Redness, heat or swelling that gets worse after a day or two can mean infection and needs a doctor.

Don’t use it if you

Are under 18, pregnant or breastfeeding, have prostate cancer or heart disease.

Bloodwork checklist

  • Complete blood count (hematocrit, hemoglobin)
  • Lipid panel (HDL, LDL, triglycerides)
  • Liver enzymes (ALT, AST)
  • Kidney function (creatinine, eGFR)
  • Testosterone, sensitive estradiol, LH and FSH
  • PSA if you are over 40
  • Blood pressure at home, weekly

Your family doctor can order these, or you can pay for private testing at labs such as LifeLabs or Dynacare. Test before you start, after 6–8 weeks, and again after you stop.
