What Zionova Testosterone 400 is

Testosterone 400 is a high-strength blend of two long-acting testosterone esters: 200 mg of testosterone cypionate and 200 mg of testosterone enanthate in every ml, for 400 mg per ml. A 10 ml vial holds 4,000 mg, so the same weekly dose takes less oil than a standard 250 mg/ml product.

Blends like this aren’t made by pharmaceutical companies; doctors prescribe single-ester testosterone. Test 400 is used mainly by people running higher doses who want fewer or smaller injections. The trade-offs are a sharper injection and a strength that makes small measuring errors bigger.

How it works

Once in the body, both esters release plain testosterone, which binds to androgen receptors to drive protein synthesis, red blood cell production and strength gains. Some of it converts to estradiol (estrogen) and some to DHT.

  • Two similar esters. Enanthate (half-life about 4–5 days) and cypionate (about 5–8 days) release at almost the same rate, so the blend behaves much like either one alone: inject once or twice a week.
  • More hormone per ml. That’s the main difference from regular testosterone. Keeping 400 mg dissolved usually needs more solvent, which is why many people find high-strength oils sting more and cause more post-injection soreness.

Side effects and risks

Testosterone 400 is usually used at higher doses, and every risk below scales with dose.

Suppression and fertility

Natural testosterone production shuts down while you use it; sperm production falls and testes shrink. Recovery after stopping can take months.

Hematocrit and clots

Higher doses push red blood cell counts up faster. Thick blood raises the risk of clots, heart attack and stroke, so check your CBC regularly.

Blood pressure and cholesterol

Expect higher blood pressure and lower HDL cholesterol at bulking doses. Monitor both, keep up cardio and keep salt in check.

Estrogen side effects

More testosterone means more conversion to estradiol: bloating, sensitive nipples and possible gynecomastia. Bloodwork tells you whether estradiol is actually high.

Injection pain and infection

High-strength oils can cause more soreness. Inject slowly into a large muscle, rotate sites and always use new, sterile equipment. Increasing heat, swelling or redness needs medical attention.

Don’t use it if you

Are under 18, pregnant or breastfeeding, have or have had prostate or breast cancer, untreated sleep apnea, high hematocrit, or heart, liver or kidney disease. In women it causes virilization that can be permanent.

Bloodwork checklist

Get tested before you start, at 6 weeks, and 4–6 weeks after you finish. At higher doses, a mid-course CBC matters most.

  • CBC: hematocrit and hemoglobin
  • Hormones: total and free testosterone, estradiol (sensitive test), LH, FSH
  • Lipid panel: HDL, LDL, triglycerides
  • Liver and kidney: ALT, AST, creatinine
  • PSA if you’re over 40
  • Blood pressure: at home, weekly

Dosing information

Clinical reference. There’s no prescription equivalent of this blend, so the reference is testosterone itself: for low testosterone, guidelines suggest 75–100 mg a week or 150–200 mg every two weeks. Doses used for bulking are often several times that, and every risk on this page rises with dose.

Talk to a doctor before use, and get bloodwork before, during and after.

Measuring at 400 mg/ml. Small volumes carry big doses:

  • 0.25 ml = 100 mg
  • 0.5 ml = 200 mg
  • 1 ml = 400 mg

Use a 1 ml syringe with fine markings, and double-check the volume before every injection.

Post-cycle therapy and support

Because both esters are long-acting, post-cycle therapy (PCT) usually starts about two weeks after your final injection. Most PCT uses a SERM, such as tamoxifen (Nolvadex) or clomiphene (Clomid), to help your body restart its own testosterone. An aromatase inhibitor such as anastrozole (Arimidex) is only worth using if bloodwork shows high estradiol with symptoms. Find these under Pairs well with below.

Common questions

Is Test 400 stronger than regular testosterone?

Not per mg. 400 mg of Test 400 has the same effect as 400 mg of testosterone enanthate or cypionate. It’s simply more concentrated, so you inject less oil.

Why does Test 400 hurt more to inject?

High-strength oils usually need more solvent to keep the hormone dissolved, and that can sting and cause soreness. Injecting slowly, warming the vial first and using large muscles helps.

How often should I inject it?

Once or twice a week. Splitting the weekly amount into two smaller injections gives steadier levels and less soreness per shot.

My vial has crystals in it. Is it bad?

High-concentration oils can crystallize when cold. Warm the vial in warm water and swirl until completely clear before use. If it won’t clear, don’t inject it.

How fast is shipping in Canada?

Orders placed before 2 PM EST, Monday to Friday, ship the same business day by Canada Post Xpresspost, with tracking.

Is Testosterone 400 legal in Canada?

Testosterone and other anabolic steroids are Schedule IV substances under the Controlled Drugs and Substances Act. Possessing them 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.
