Quality Assurance: Laboratory tests and analysis


The history of Winstrol Stanozolol

Stanozolol was discovered in 1959. The US Food and Drug Administration approved it in 1962 under the name of Winstrol.

Bodybuilders and other athletes realised that they could help them gain weight or become more competitive and started using it. Sports federations banned it eventually, because they considered it a drug that helped improve performance. Its approval was achieved after some modifications to the rules that regulate the pharmaceutical industry. 

Winstrol was withdrawn from the U.S. market in 2010 but can still be obtained with a prescription to address hereditary angioedema, anaemia and breast cancer. Currently, the pharmaceutical quality Winstrol is sold exclusively by prescription, but it is available in many serious sale sites.


Injectable Winstrol is usually a suspension against a solution. Suspensions have small particles that are visible to the naked eye. If they are left for several days in the tray, particles will sink, turning the solvents transparent and leaving the water on top. According to the manufacturer, the size of the particles varies, which means that certain Winstrol preparations can clog a 22-gauge needle. Ultra-micronized Winstrol can easily get through a 25-gauge needle, which makes injections more comfortable.

Due to the different sizes of the particles, Winstrol can remain active in the blood for several days once injected. In short, the solution comes almost immediately to the blood during the injection. A few days later, the body slowly absorbs solid particles. 

From a practical point of view, it is known that Winstrol leaves painful lumps at the injection site and causes infections and/or abscesses. This is because many clandestine laboratories do not place steroids together correctly, which cannot be attributed to Winstrol itself. 

 “The manufacturer of pharmaceutical products should be privileged; it would be ridiculous to take a product from a clandestine laboratory”. Arnaud Sylvain

According to some sources, the aqueous injectable version of Winstrol can be taken orally, which means that you can technically drink your Winstrol aqueous solution, but it was proven that the injection worked better in a gradual way than the oral administration in terms of retention of nitrogen. However, it should be known that injectable Winstrol has a very exotic taste.

The peculiarity of the Stanozol is that it also exists in oral version. It is important to keep in mind that both oral and injectable versions are methylated. Which means that both versions will be toxic to the liver. You will have to use a liver support supplement, no matter what version you take and how you use them.

Winstrol, in both the injectable version and the oral version, is basically the same. Liver toxicity and bioavailability of the drug are exactly the same, whether you take the drug orally or you inject it. Taking it orally doesn’t mean the drug is toxic to the liver, it’s rather the chemical structure of the 17-alpha-alkylated carbon of the drug that makes it toxic to the liver.

By way of conclusion, it is imperative to choose and inject UGL water-based Winstrol only if it comes from a regulated or trusted laboratory, manufactured under strict quality standards.


For quality muscle growth, there are many kinds of anabolic steroids out there. While all have potential side effects, Winstrol has many characteristics that make it more attractive than others. Winstrol helps generate quality muscle growth. Some anabolic steroids help to develop the size of the muscles without increasing strength. Combined with serious training, Winstrol generates strong muscles. 

Many anabolic steroids encourage water retention. Winstrol does not cause any water retention, so it is a good option for many bodybuilders when they have a competition getting close in their calendar. Winstrol allows consumer to keep developing muscles without retaining the fluid that hampers the hard, venous and dry appearance, which is an important part of the bodybuilder’s body. 

Winstrol improves body’s ability to make red blood cells. Red blood cells carry oxygen throughout the body, including muscles. More red blood cells allow the muscles to work more, for longer and recover faster due to the supply of additional oxygen. That is why some athletes (from disciplines such as athletics, cycling and runners) can take Winstrol if they want to since it is a substance that improves performance.

Some bodybuilders and athletes from endurance disciplines use Winstrol because it provides strength and endurance without creating volume. Athletes of endurance disciplines do not want to carry more weight than necessary, so they avoid having bulky muscles at all times.

Get the quality of your Winstrol checked

Winstrol can come from clandestine laboratories. Needless to say, it is preferable to play Russian roulette than consuming these types of products. In 2018, the offer in the market makes it possible to no longer buy products from these pseudo-laboratories, since legal brands produce them and sell them at very good prices.

Therefore, it is essential to purchase your product from reputable sources whose suppliers are well-known laboratories with an unblemished reputation.

 “Nowadays the pharmaceutical stanozolol is obtained at prices around 25 euros, so it would be crazy to buy underground products.” Arnaud Sylvain.

Here are some details of the manufacture process:

  1. Each pill/vial must contain the correct amount of raw material. Be careful with low-dose pills/vials. Only a fully automated production line makes this possible. In fact, only a legal laboratory can confirm this information.
  2. Laboratory tests on raw materials and finished products should be provided by the laboratory. Brands can also provide tests from other external laboratories. Users can even review the products by themselves if they so wish. An independent site like anaboliclab.com is a reference.
  3. Elements of protection against counterfeiting are important, including verification codes, which can be verified on the site of the brand. You can tell if your product is authentic or not.





Dianabol remains the preferred product, even for the most experienced users, who, as is well known, use it frequently because of its remarkable ability to help lose weight and for a gain of dry mass.

Winstrol, if taken orally, is perfect for beginners, while injectable Winstrol is used rather by intermediate or advanced users.
