01The basics

What Zionova Clenbuterol is

Zionova Clenbuterol contains clenbuterol hydrochloride, 50 mcg per tablet with 50 tablets per bottle. Clenbuterol is a bronchodilator (an airway-opening drug) used for asthma in some countries and for horses in others. It isn’t approved for human use in Canada.

It’s popular for cutting because it raises metabolism and body temperature. It also stimulates the heart, and serious heart problems have been reported in people using it to lose weight. If you’re considering it, read the risks before anything else.

03How it works

How it works

Clenbuterol is a beta-2 agonist, a cousin of asthma inhalers such as salbutamol, but much longer-acting.

  • Thermogenesis: it raises heat production and the rate at which fat is released and burned.
  • Muscle sparing: in animals, it reduces muscle breakdown; evidence in people is limited.
  • Long half-life, about 36 hours, so levels keep building for several days and linger after stopping.
  • Tolerance: the receptors become less responsive within a few weeks.

04Half-life

Half-life, in plain numbers

A half-life of about 36 hours means half of what is in the body is gone after that time, then half of the rest, and so on. For a tablet this is mostly about how fast the liver clears it; food and the person change it a little.

05Clinical reference

Dosing information

Clinical reference. Where clenbuterol is approved for asthma, adults usually take 20 mcg twice a day (40 mcg daily).

One Zionova tablet is 50 mcg, more than that whole daily amount. Heart risks rise with dose. Talk to a doctor before use.

06Measure 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.

08Risks

Side effects and risks

Some side effects are near-universal. The heart risks make clenbuterol one of the more dangerous products for fat loss.

Heart

Racing heart, palpitations and abnormal rhythms are common. Heart attacks and heart muscle damage have been reported. Chest pain or fainting: call 911.

Shakes and jitters

Hand tremors, anxiety and restlessness are very common, especially at first.

Insomnia

Its long half-life disrupts sleep. Take it early in the day.

Electrolytes and cramps

It lowers blood potassium, causing painful cramps and adding to heart rhythm risk.

Blood pressure and sugar

Both can rise, along with headaches and sweating.

Don’t use it if you

Have any heart condition, high blood pressure, an overactive thyroid, an anxiety disorder or diabetes, take stimulants, beta-blockers or diuretics, are pregnant or breastfeeding, or are under 18.

09Interactions

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.

  • SeriousBeta-blockers

    Propranolol, metoprolol and others cancel the effect, and non-selective ones can set off bronchospasm in people with asthma.

  • SeriousOther stimulants

    Caffeine pills, ephedrine, yohimbine, amphetamines and thyroid hormone all add to heart rate, blood pressure and the risk of an irregular heartbeat.

  • CautionDiuretics, corticosteroids and insulin

    Beta-2 agonists pull potassium into cells. These drugs lower potassium too, and low potassium brings cramps and heart-rhythm problems.

  • CautionMAO inhibitors and tricyclic antidepressants

    Stronger effects on the heart and blood vessels.

  • CautionDrugs that prolong the QT interval

    Some antibiotics, antipsychotics and antiarrhythmics; together with a beta-2 agonist the heart-rhythm risk adds up.

10Safety

Checks before and during

  • ECG before you start, ideally
  • Resting heart rate and blood pressure each morning
  • Potassium and magnesium levels
  • Thyroid (TSH) and fasting glucose
  • No other stimulants: caffeine, pre-workouts, yohimbine, decongestants

11Tips

Using it more safely

  • Take it in the morning only.
  • Cut caffeine and other stimulants.
  • Drink plenty of water and eat potassium-rich foods.
  • Check your resting pulse daily and stop if it stays high.
  • Avoid long or hot training sessions where you could overheat.
  • Stop immediately for chest pain, fainting or severe palpitations.

14Questions

Common questions

How is this different from Clen 75 by Genetix Pharma?

Same drug. Zionova’s tablets are 50 mcg; Genetix’s are 75 mcg. Compare them under Compare brands on this page.

Why does clenbuterol stop working after a few weeks?

Beta receptors become less responsive with continued use. That’s why the effect fades, and why taking more to chase it raises risk.

Is clenbuterol a steroid?

No. It’s a beta-2 agonist. It doesn’t affect testosterone and doesn’t need PCT.

How fast is shipping in Canada?

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

Is clenbuterol legal in Canada?

Clenbuterol isn’t approved for human use in Canada. It isn’t an anabolic steroid and isn’t listed in the Controlled Drugs and Substances Act. It’s banned in tested sport.

How is my order packaged?

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