01The basics

What Winstrol by Genetix Pharma is

Genetix Pharma’s Winstrol contains stanozolol, an oral anabolic steroid made from DHT, with 50 tablets per bottle; the tablet strength is in the specifications below. Stanozolol was developed in the 1960s and prescribed for years to prevent attacks of hereditary angioedema.

In sport, it’s known for adding strength and a dense, dry look without extra bodyweight. It’s also one of the toughest steroids on cholesterol and, as a 17-α-alkylated oral, on the liver. This page covers both sides.

03How it works

How it works

Stanozolol activates androgen receptors and strongly lowers SHBG, the protein that binds testosterone in the blood.

  • No estrogen: it doesn’t aromatize, so no estrogen-driven water retention.
  • Oral activity: a methyl group at the 17-α position lets it survive digestion, at the cost of liver strain.
  • Half-life about 9 hours, so many people split the daily amount.

04Half-life

Half-life, in plain numbers

A half-life of about 9 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.

A textbook model built from the half-life alone. Real numbers vary from person to person.

05Clinical reference

Dosing information

Clinical reference. For preventing hereditary angioedema attacks, stanozolol was started at 2 mg three times a day and then reduced to the lowest dose that worked, often 2 mg a day or less.

Each Genetix tablet contains many times a single clinical dose. Doses used for physique goals are far above medical use, and every risk on this page rises with them.

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

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

Stanozolol is often seen as a “light” steroid. Its effects on lipids and the liver say otherwise.

HDL cholesterol

Studies show stanozolol can cut HDL by half or more within weeks, more than injectable testosterone at similar doses.

Liver enzymes

ALT and AST commonly rise. Avoid alcohol and other orals and keep courses short.

Joints and tendons

Achy joints are often reported. Heavy lifting on painful joints raises injury risk.

Hair, skin and prostate

DHT-like effects: acne, scalp hair loss in prone men, and possible prostate effects.

For women

Virilization, including a deeper voice and facial hair, can be permanent.

Don’t use it if you

Are under 18, pregnant or breastfeeding, have liver or heart disease, high cholesterol or high blood pressure, or are taking another oral steroid.

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.

  • 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.

10Bloodwork

Bloodwork checklist

Test before you start, at 3–4 weeks, and 4–6 weeks after you finish.

  • Lipid panel, especially HDL
  • Liver panel: ALT, AST, GGT, bilirubin
  • Testosterone, LH and FSH
  • CBC and blood pressure

11After a course

Post-cycle therapy and support

Stanozolol suppresses natural testosterone, so it’s usually used with an injectable testosterone, followed by post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid). It doesn’t aromatize, so it doesn’t need an aromatase inhibitor. See Pairs well with below.

14Questions

Common questions

How does it compare to Zionova Winstrol?

Both contain stanozolol tablets, 50 per bottle. Check the strength in each product’s specifications, and compare them under Compare brands on this page.

Does Winstrol burn fat?

Not directly. It helps you keep muscle and strength while dieting, and because it adds no water, you look leaner at a given body fat.

Why is HDL so important on Winstrol?

HDL helps clear cholesterol from your arteries. Stanozolol can lower it sharply, and low HDL is linked to heart disease, so it’s the first number to check.

How fast is shipping in Canada?

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

Is Winstrol legal in Canada?

Stanozolol is an anabolic steroid, listed in Schedule IV of the Controlled Drugs and Substances Act. Possessing it 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.
