In this guide we'll cover Winstrol side effects, positive traits, best uses, cycles, PCT, price and more... 

Winstrol is the brand name for Stanozolol, a dihydrotestosterone (DHT) derivative steroid. In bodybuilding circles, the drug is better known as 'Winny'.

Winstrol is one of the most popular anabolic androgenic steroids of all time. Only testosterone and Dianabol are more popular.

The steroids biggest attraction is its versatility. You can use it in cutting cycles or at the end of a bulking cycle to polish and harden muscle gains. It's also one of the few compounds available as an oral and injectable.

Winstrol high anabolic activity increases strength, power and endurance, which makes it a firm favorite with high-performance athletes. It's also infamous as many athletes careers have imploded after testing positive for Winstrol.

Probably the most famous is Ben Johnson. The Canadian sprinter won the gold medal 100m sprint at the 1988 Seoul Olympics destroying the rest of the field including favorite Carl Lewis of the USA.

Unfortunately, Johnson tested positive for Stanozolol, was stripped of his medal and banned for 3 years. His career never recovered.

Winthrop Laboratories, the company behind Stanozolol, launched the steroid onto the UK prescription drug market in 1959. Its holding company Sterling, began marketing the steroid to the US market from 1961.

Winstrol is used to treat a variety of conditions from muscle wasting diseases, bone fractures and children with growth deficiencies.

Chemical Profile

Stanozolol is a modified derivative of the androgen sex hormone dihydrotestosterone (DHT).

The first modification is the addition of a pyrazole compound group to the first A-ring of Stanozolol's chemical structure. This has the effect of increasing the steroids anabolic activity and suppressing its androgenic side effects.

The second modification is the addition of a methyl group to the 17th (C17-alpha alkylation) carbon position. This is common in oral steroids because the methyl group protects the steroid from being destroyed by the liver's metabolism.

Winstrols Anabolic Androgenic Strength Rating

These modifications give Winstrol a high anabolic to low androgenic strength ratio. The anabolic strength rating is 320, 3 times higher than testosterone.

In contrast, the androgenic strength is only 30, which is one of the mildest and 30% lower than testosterone.

Positive Traits and Effects 

Most DHT derivative anabolic androgenic steroids have the common trait of retaining lean muscle mass while helping to lower body fat.

Winstrol gains are clean and dry because they don’t carry any of the water retention common in bulking steroids such as Dianabol.

Bodybuilders don't consider Winstrol to be a true bulking steroid as it doesn't deliver the size gains of Dbol or Deca.

However, athletes love Winstrol. The steroids ability to increase strength, without adding bulk makes it a firm favorite with performance athletes.

SHBG Suppression

Another important trait is Winstrol's ability to suppress SHBG (sex hormone binding globulin) levels. SHBG is a protein that binds to other sex hormones and prevents them from doing their jobs.

"SHBG suppression is a common trait shared with many steroids but, Winstrol’s is stronger, even at low doses."

Studies show the drug can suppress SHBG by as much as 50% in as little as 3 to 4 days.

Less SHBG in the body means more free testosterone is available to use to build muscle tissue.

Furthermore, Stanozolol stops SHBG binding to other synthetic anabolic hormones.

These two factors combined create a more potent anabolic activity in the muscle tissue, especially when Winstrol is stacked with other steroids.

Winstrol Does Not Aromatise 

DHT derivative steroids don't aromatise and convert to conversion to estrogen. this rules out the estrogen side effects water retention and gynecomastia.

Winstrol enhances protein synthesis, increases nitrogen retention and to a lesser degree, increases red blood cell counts.

These traits may not be as powerful as other steroids, but when you take into the consideration its SHGB suppression ability combined with the mild androgenic side effects, Winstrol is a very well rounded compound.

Winstrol Cycles and Uses

Winny's versatility is one its major strengths as it can be used in cutting and bulking cycles.


Winstrol's traits are more suited to a cutting cycle than a bulking cycle.

It will build muscle but you're not going to see the huge gains in size that you get with other oral steroids.

Instead, the gains are leaner.

Winstrol has the effect of drawing more water out of the body because it doesn't bind to the aromatase enzyme. This gives a leaner, dryer and vascular look.

Stanozolol really excels at preserving lean muscle. For this reason, competitor bodybuilders run either a winny only cycle or stack it with testosterone as part of their competition prep.

What's more, Winny helps to suppress the appetite, which makes life easier during a calorie deficit.

Does Winstrol make you lose weight?

There's a lot of misinformation surrounding Winstrol, especially when it comes to fat loss.

For example, the questions below are regularly asked on bodybuilding forums;

"Is Winstrol a fat burner?"

"Does Winstrol burn fat?"

"Can I use Winstrol for weight loss?"

The fact is, Winstrol is not a fat burner or a weight loss drug. It won't make you lose 20 pounds of fat while lying on the couch stuffing your face with potato chips.

How to Cycle Winstrol to lose Weight

To really benefit from Winstrol you need to be in great shape, preferably below 10% body fat. At this BF%, Winstrol is much more effective at removing stubborn fat deposits around the abdominals and lower back.

If you're over 15% body fat, don't run a Winstrol cutting cycle thinking it's going to lower it. At that BF%, the only thing lowered are your good cholesterol levels.


It may be 3 times more anabolic than testosterone but Winstrol is not a great bulking steroid. You'll never get the bulk that Dbol or even Deca can give you.

This doesn’t mean Winny shouldn't be used in a bulking cycle.

In fact, many consider Stanozolol's ability to suppress SHGB makes other compounds effective when they are stacked with Winny.

In theory its idea but, the best bulking cycles always involve at least one oral and adding another makes the cycle very toxic.

For this reason, Winstrol is often taken near the end of a bulking cycle to harden and dry out the muscles.

Athletic Performance

Winny's ability to increase strength and power endurance without adding bulk makes it the perfect steroid for athletic performance.

"Increases in strength, power and endurance without the bulk make it the perfect athletes steroid"

The steroids most powerful quality is delivering immense strength and its common to experience increases in strength by 40% or more. 

Strength is very important in athletics as it increases speed and agility.

What's more, the increased strength doesn't come with excessive weight or bulk. This is a big advantage in sports where bulk and weight is a hindrance.

Winstrol Stanozolol Side Effects

It may be a milder steroid, but Winstrol has side effects you need to be aware of.

The following Stanozolol side effects are in order of severity

Good and Bad Cholesterol

Stanozolol has a notorious reputation for reducing good cholesterol and increasing bad cholesterol.

Before running a Winstrol steroid cycle have your blood work done to ensure the LDL (Low-Density Lipoproteins) and HDL (High-Density Lipoproteins) levels are normal.







Winstrol is often mistaken as a fat burner. It can help to reduce stubborn fat, but you have to have a low body fat percentage to see the benefits.

If you're overweight Winstrol is potentially dangerous as it can result in high cholesterol levels.

Also, an oral Winstrol cycle can increase the negative effect on your blood lipid levels compared to the injectable form.

To combat the negative effects on cholesterol eat a healthy diet that's low in fat and take regular cardiovascular exercise.


All C17-AA steroids, including oral Winstrol tablets, are potentially toxic to the liver.

C17-Alpha-Alkylated oral steroids are modified to survive the liver's metabolism. However, this has the effect of increasing the liver enzyme levels which is an indicator of stress.

High enzyme levels do not mean the liver is being damaged it's an indicator that it's having to work harder to allow the drug into the bloodstream.

However, damage can happen if high doses are taken over prolonged periods.

The level of stress depends on the oral steroid you're using. For example, Winstrol is less toxic than Dianabol but more toxic than Anavar(Oxandrolone).

5 Ways To Protect and Limit Liver Stress  

  1. Get your liver checked before a cycle.
  2. Avoid alcohol and prescription medications  
  3. Limit Winstrol cycle to 6 to 8 weeks max.
  4. Drink plenty of water
  5. Take a good quality liver support supplement

The dosage and duration are important factors in determining the potential risk of liver damage. A low Winstrol oral dosage has a mild effect on liver enzyme levels. Although, the risk increases when the dosage goes up.

Again, tolerance of the side effects depends on the individual. That’s why it's important to take things slowly and monitor closely how the body reacts.

It's important to protect the liver no matter how mild the steroid. The last thing you want is a stressed out liver as you'll feel tired and lethargic with no motivation to work out.

Natural Testosterone Suppression

Does Winstrol affect testosterone levels?

All steroids suppress natural testosterone production, but Winstrol is particularly suppressive, even at a low dosage.

In one study, a 10 mg Stanozolol dosage suppressed natural testosterone by as much as 55% within 2 weeks of administration.

Winstrol won't shut you down completely, but it will put you in a very low testosterone state.

You'll want to avoid this because low testosterone has many short and long term side effects that inhibit muscle growth.

For this reason, a Winstrol and test cycle is recommended over a Winstrol only cycle as the exogenous testosterone temporarily stabilizes T levels. Taking a good quality testosterone booster during and post cycle will also help to maintain healthy levels.

Natural testosterone levels will begin to recover once the cycle ends. But this takes time. Running a PCT is important as it speeds up the recovery time so that levels get back up to normal as fast as possible.

Again, get your testosterone levels checked as they need to be normal before taking steroids.

Winstrol’s Androgenic Side Effects

Stanozolol has a mild androgenic rating of 30. Therefore, androgenic side effects are virtually non-existent at very dosages. But those predisposed to androgenic side effects need to be careful.

"Men genetically predisposed to male pattern baldness have a greater risk of their hairlines receding faster on Winstrol."

The big culprit is dihydrotestosterone (DHT) - the hair follicles worst enemy.

DHT restricts the ability of the follicles to produce hair by choking off the nutrients it needs to grow.

Many try in vain to stop their hair loss with DHT inhibitors such as Finasteride or Dutasteride.

 Unfortunately, this is a complete waste of time because Winstrol is already a DHT.

If you're genetically sensitive to acne you're likely to have the same problem. Keeping the skin clean will help to limit the effects. At higher doses, men and women can experience skin rash.

Winstrol Side Effects for Women

As with Anavar, Winstrol is well tolerated by women, but virilization side effects are a concern.

Common Winstrol virilization side effects include excess body and facial hair, deepening voice and an enlarged clitoris.

At lower doses virilization risks are minimal. They become a problem as the Winstrol pills dosage increases. In certain women, high doses can interfere with the menstrual cycle.

Viralization Symptoms That Can Effect Women On Winstrol

  • Excess Facial Hair 
  • Excess Body Hair 
  • Deepening Voice 
  • Clitoris Enlargement 
  • Delayed Menstrual Cycle 

Again, genetic's are a major influence on how tolerant you'll be. Always start with a low dosage and monitor reactions closely. If signs of virilization do appear stop taking the drug immediately.

Stanozolol can dry you out to the point that it causes sore joints. This is an issue if you're overdoing it with weight training and a common problem with the extra strength Winstrol gives you.

To ease the pain, rub magnesium oil into the joints and take plenty of fish oil and omega 3 fatty acids.

How To Take Winstrol

Winstrol Dosage for Men

For men the standard oral Winstrol dosage is 25mgs per day and 50mgs for the injectable form which would be administered every second or third day.

For most men, these doses will deliver impressive results in strength and muscle hardening as well as the control of potential side effects.

For competitive bodybuilding purposes, doses are commonly increased to 50mgs per day for both oral and liquid Winstrol.

Hardcore users take up to 100mgs per day. But with Stanozolol's hepatotoxic nature, high-end doses should be limited to 7 days and run at the end of a comp prep cycle.


 25 to 50 milligrams

per day 


5 to 10 milligrams

per day 

Winstrol Dosage for Women

Most women tolerate Stanozolol at low doses and experience impressive results.

The most common oral dosage for a female winny cycle is 5 to 10 milligrams . At this dose, most women enjoy the anabolic effects of Winstrol without the virilization side effects.

But, beginners should start at the lowest dosage to determine how tolerant they are to the side effects.

Injectable Winstrol for women is less common because dosages are harder to control and the side effects can be more potent.

Although, female bodybuilders do inject and a Winstrol injection dosage of 20 milligrams every 3 to 4 days is a common practice.

A Winstrol cycle for women generally runs for 4 weeks. The cycle can be extended to 6 weeks for experienced female bodybuilders and athletes.

Half Life 

Injectable Stanozolol has a half life of 24 hours while oral tabs have a half-life of 9 hours.

Winstrol PCT (Post Cycle Therapy)

Always have a blood check before starting a Winstrol oral cycle as you’re blood lipids, testosterone levels and liver enzymes need to be in good shape.

Also, a PCT should be planned out before you cycle. Anabolic steroids suppress your hormones and a PCT is essential to stabilizing the hormonal system.

After the cycle have your blood checked again as these results determine how to run the PCT.

Preventing Testosterone Dropping Too Low

To counteract Stanozolol suppressive nature an exogenous form of testosterone can be used to prevent natural testosterone levels dropping too low.

At the end of the cycle, your testosterone levels will begin to recover, but the process takes time.

The longer your testosterone levels remain low the more gains are lost. To maintain as many gains as possible you need to recover fast.

The most common approach is a 10 day course of Clomid or Nolvadex. Many consider Nolvadex a better choice when using Winny because of its positive effects on LDL (bad) cholesterol.

Taking a good quality T-Booster will also help you recover faster.

Keeping The Liver as Healthy as Possible

It's important to protect your liver from potential damage when taking any C-17 alkylated oral steroids.

You can protect the liver with liver cleanser supplements including milk thistle and choline. Drinking plenty of water during the cycle will also help cleanse the liver.

A Stanozolol cycle can increase cholesterol levels, therefore eat a clean low-fat diet and avoid processed crap. Increasing your intake of omega 3 fatty acids and taking regular cardio workouts are also good ideas.

A full blown PCT cycle should run for 8 weeks with another 4-week clean break (12 weeks in total) before running another cycle.

Where To Buy Winstrol

Both oral and injectable Winstrol is widely available to buy on the black market. The only problem you'll find is getting your hands on quality pharmaceutical grade Winstrol.

There are reputable underground labs out there however, these are heavily outnumbered by labs selling crap.

Look out for premium brands such as Alpha Pharma. They produce a quality Stanozolol hormone product in both injectable and oral pills. The injectable is called Rexogin and the oral is called Rexobol.

Another quality brand is British Dispensary and they produce Stanozolol under the name Azolol.

How Much Does Winstrol Cost?

Giving an exact Winstrol price is difficult as there are many variables involved when buying on the black market. Production costs and dosage concentrations will effect the price.


$1 - $3 per 5mg tab


$50 - $120 per 10ml vial*

* 10ml vial containing 50mg of stanozolol

Generally, Winstrol 50 mg tabs retail for $1.00 to $3.00 per tab. However, Winstrol tablets are also available in 5, 10 and 25-milligram tabs and these will work out cheaper per unit.

Injectable Winstrol is more expensive. 10ml vials containing 50mg of Stanozolol can cost between $50 to $120 per vial.

Buying Winstrol Online - Be Careful

If you decide to buy Winstrol online use your due diligence. Underground Labs are not regulated and there's no guarantee whether the Winstrol tablets for sale are authentic, faked, under-dosed or contaminated.

Is Winstrol Legal?

There are legal implications you need to be aware of when buying stanozolol online.

It is illegal to buy and possess Winstrol in the US and the Federal Govt is very strict on the buying and possession of controlled substances.

Under the Steroid Control Act, Winstrol is classified as a schedule III controlled substance and can only be purchased legally with a prescription.

But even a doctor's prescription isn't enough to make possession legal as the Federal Government must be convinced that the medical need is justified.

The consequences of breaking the law are severe. You can expect heavy fines of up to $250,000 and a maximum of 3 years in prison. Other countries are as strict while others are more lenient.

It's your responsibility to learn and understand the laws in your country before deciding to buy Winstrol or any anabolic steroid without a prescription.

Are There legal Alternatives?

Fortunately, yes.

Legal anabolic steroids have similar benefits but without the side effects or you having to break the law.

Winsol is a leading legal alternative to Winstrol and is suitable for male and female bodybuilder's, athletes and gym goers.

Winsol can be used as a pre-workout supplement to boost strength and endurance. It also contains high concentrations of top grade amino acids to help you build and retain quality lean muscle mass.

BTW, Winsol doesn't require a doctor's prescription and is completely safe. For more details, click here
