01The basics

What Zionova Superdrol is

Superdrol is the street name for methasterone (methyldrostanolone), an oral anabolic steroid. Each Zionova tablet contains 10 mg, with 50 tablets per bottle. It was first made in the 1950s but never sold as a medicine. In the mid-2000s it appeared in “supplements”, until regulators acted on reports of serious liver injury.

It produces fast gains in dry muscle and strength, and it’s widely considered one of the most liver-toxic orals available. If you’re considering it, this page is the one to read in full.

03How it works

How it works

Methasterone is closely related to drostanolone (Masteron), with a methyl group added so it can be swallowed.

  • Strongly anabolic: big gains in strength and muscle fullness without estrogen-driven bloat.
  • 17-α-alkylated: this lets it survive the liver as a tablet, and it’s why liver injury is the main concern.
  • No aromatization, though some users still report water and blood pressure changes.

04Clinical reference

Dosing information

Clinical reference. Methasterone has never been approved or studied as a medicine, so there’s no clinical dose.

Most liver injury reports involved courses of several weeks. Every risk on this page rises with dose and with each additional week.

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

05Measure it

Measure it

Type in the amount your prescriber gave you, or the one you are working from, and this turns it into what to draw up or count out from this exact product. It only does the arithmetic; it never suggests an amount.

Arithmetic from the strength printed on this product. Always check your own vial or bottle, follow your prescriber, and ask a pharmacist to show you how to measure if you are unsure.

06Risks

Side effects and risks

Published case reports describe severe liver injury, including jaundice and hospital stays, in people taking methasterone.

Liver injury

Cholestatic liver injury (bile backing up in the liver) has been reported repeatedly. Yellow skin or eyes, dark urine, pale stools or itching mean stop and see a doctor immediately.

Cholesterol

HDL can drop sharply. Combined with the other effects, it strains the heart.

Blood pressure

Rises are common. Check at home every few days.

Lethargy and appetite loss

Fatigue, back pumps and reduced appetite are frequently reported, and they can be early signs of liver strain.

Suppression

Natural testosterone drops quickly, even on short courses.

Don’t use it if you

Are under 18, a woman, drink alcohol regularly, have any liver, kidney or heart condition, high blood pressure, or are taking another oral steroid or liver-straining medication (including high-dose acetaminophen).

07Interactions

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

    Oral anabolic steroids can multiply warfarin’s effect. Large INR jumps and bleeding are on record, and the anticoagulant dose often has to be cut sharply.

  • CautionAlcohol, acetaminophen and other liver-heavy drugs

    Drinking, regular high doses of acetaminophen (Tylenol), isotretinoin and some antifungals all load the same liver that this tablet already strains.

  • CautionInsulin and diabetes tablets

    Blood sugar can drop, so diabetes medicines may need changing.

  • CautionPrednisone and other corticosteroids

    Extra fluid retention and swelling, a concern with heart or kidney problems.

  • Good to knowA second oral steroid

    Two 17-alpha-alkylated tablets at once stack their liver and cholesterol effects. Doctors never prescribe them together.

08Bloodwork

Bloodwork checklist

Test before you start, after 2 weeks, and 4 weeks after you finish. Liver changes can happen fast.

  • Liver panel: ALT, AST, GGT, ALP, bilirubin
  • Lipid panel
  • Hormones: testosterone, LH, FSH
  • Kidney function and a CBC
  • Blood pressure at home

09After a course

Post-cycle therapy and support

Superdrol suppresses natural testosterone, so post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) is commonly used after a course. More important is protecting your liver: no alcohol, no other orals, short courses and bloodwork. See Pairs well with below.

12Questions

Common questions

Is Superdrol a prohormone or a steroid?

It’s an anabolic steroid. It was marketed as a supplement in the 2000s, but methasterone is an active steroid, not a precursor.

How hard is Superdrol on the liver?

It’s considered one of the harshest orals. Case reports describe severe cholestatic liver injury, sometimes after only a few weeks.

What are “back pumps”?

Painful cramping in the lower back muscles during exercise, commonly reported with Superdrol and other strong orals.

How fast is shipping in Canada?

Orders ship by Canada Post Xpresspost, with tracking within 72 hours of payment, with tracking.

Is Superdrol legal in Canada?

Methasterone is an anabolic steroid. Anabolic steroids are listed in Schedule IV of the Controlled Drugs and Substances Act: possessing them for personal use isn’t an offence, but trafficking, importing and exporting without authorization are.

How is my order packaged?

In a plain, unbranded box with no product names on the outside.
