Winstrol (Stanozolol)

winstrolWinstrol (17β-Hydroxy-17-methyl-5alpha-androstano[3,2-c]pyrazole) developed by Winthrop labs is the brand name for Stanozolol. Available in both oral and injectable versions, this Anabolic Steroid is one of the top used Steroids of all time. Many people may have heard about Winstrol because of Canadian sprinter Ben Johnson who tested positive for this Steroid during the 1988 Olympics held in Seoul.

First developed to help treat conditions such as muscle wastage, burn victims and Osteoporosis, however most use it now for its muscle building effects and usually obtain it illegally through the black market.

Properties of Winstrol

As with Anavar, Winstrol is also a derivative from DHT. Winstrol contains a 3-2 Pyrazol group which is attached to the A-Ring of the DHT structure. This change to the A-Ring structure gives Stanozolol its high binding affinity to the Androgen receptors within the muscle tissue of the human body.

To allow Stanozolol to enter the blood stream it has methyl group with is attached to the 17th carbon. Other oral Steroids such as Anavar, Anadrol and Dianabol have this same modification, without it oral Steroids would be rendered useless. This modification allows the Steroid to survive being broken down by the liver.

Winstrol Cycle and Dosages


Used mainly in cycles where the end goal is fat loss and lean muscle. Due to Winstrol not being a great muscle building Steroid, it would be a waste of time using this Steroid in a bulking cycle. Winstrol is almost always used by bodybuilders alongside other Steroids such as Trenbolone and Masteron pre-contest.

Although Winstrol should not be taken for longer than 6 weeks due to its toxicity on the liver, the injectable version is often used for 8 to 10 weeks as it only has to pass through the liver once and is therefore less toxic. Dosages are often between 40 and 80mg daily when taken orally and 100mg every 2 days when injected. It must be noted that injecting Winstrol can often be extremely painful and often users rather opt for the oral option due to this. The reason for the painful injections is because Wnstrol Depot (the injectable version of Winstrol) is in suspension form and is not 100% dissolved into the water. There have been reports of underground labs producing an oil based injectable version that is far less painful.

Winstrol Side Effects

While mild and considered one of the safer Steroids to use, Winstrol still has side effects. Many users may not see side effects while more sensitive users may. Winstrol does not convert to estrogen, so side effects such as Gynecomastia and Water retention are not a problem with this Steroid. This is the reason why Winstrol is the most popular Steroid when it comes to cutting cycles.

Being an oral Steroid and containing the attached methyl group to the 17th carbon, liver issues can be a problem if this Steroid is used for prolonged periods of time or is taken in large dosages. Using a liver aid such as Liv52 or Milk Thistle is always recommended.

Although lower than stronger Steroids, HPTA suppression still occurs with Winstrol and thus the need to run a PCT once the cycle is over.

Other side effects such as Acne, hair loss, high blood pressure, aggression as well as others are all a possibility when using this Anabolic Steroid.

Buying Winstrol

Being one of the most popular Steroids around, Winstrol is usually easy to purchase. Whether it be from an online source or from a dealer at your gym, buying Winstrol can be achieved with little effort and usually at a low price. If you choose to buy Winstrol there are some things to look out for such as the brand you are buying, the amount of tablets or capsules in a bottle and the strength of the tablets/capsules. Buying a well-known brand may cost more but is always the best choice as there is little to no risk that the product will be fake or under dosed. The strength of the tablets also plays a big roll. Some brands offer Winstrol in 10mg tablets while others offer it in 50mg tablets.
