Winstrol was first developed by Winthrop Laboratories in Great Britain and hit the pharmaceutical market in full force in 1961. The trade name Winstrol has changed hands many times over the years, but the active steroidal hormone that it is comprised of is manufactured by numerous pharmaceutical companies and underground labs (UGLís) around the world. Unfortunately, due to this being an extremely popular anabolic steroid it is counterfeited quite a bit. You will need to exercise caution when buying Winstrol or you could easily end up wasting your money.

Without question, this is an extremely popular anabolic steroid, not only among athletes but the general population. Many people outside of performance circles cannot name the first anabolic steroid, but if they can it is almost always Winstrol. This steroid gained worldwide attention during the 1988 Summer Olympic Games when Canadian Sprinter Ben Johnson won the gold by defeating the heavily favored American Carl Lewis and then tested positive for the steroid. It has also appeared in news headlines many times since in high profile athletic based stories.

Winstrol Basics:

Winstrol is a dihydrotestosterone (DHT) derived anabolic steroid comprised of the steroidal hormone Stanozolol. It is highly anabolic and only slightly androgenic with a ratings of 320 and 30 in each category respectively. Winstrol represents a steroid with one of the largest gaps between anabolic and androgenic ratios.


Winstrol is available as an oral or injectable steroid. Both forms are identical in every single way other than the mode of administration. Both are Stanozolol, both carry the same benefits, the same possible side effects and both are C17-alpha alkylated (C17-aa) anabolic steroids. As C17-aa steroids, both carry a significant hepatotoxic nature. Injectable Winstrol represents one of the few injectable C17-aa steroids.

Winstrol has the ability to increase red blood cell count and to enhance protein synthesis and nitrogen retention. This gives the steroid a strong anabolic punch but it is another trait that separates if from many others. Winstrol will greatly reduce SHBG, thereby, increasing the amount of free testosterone now available to the body. Itís not the only steroid that carries this trait, but few do anywhere near the level of Winstrol.

Side Effects of Winstrol:

Winstrol is generally considered a well-tolerated steroid for most healthy adults. It can come with a few concerns; however, responsible use will normally remedy any complications that may occur. To help you understand the side effects of Winstrol with ease, we have broken down the common related categories associated with anabolic steroid use.

∑ Estrogenic: Winstrol does not aromatize and cannot produce any estrogenic related side effects. This means gynecomastia and water retention is impossible with this steroid. High blood pressure is something that can occur due to water retention, but thankfully that will not be an issue with Winstrol.

∑ Androgenic: Androgenic side effects of an anabolic steroid are commonly caused by testosterone being reduced to DHT through the 5-alpha reductase enzyme. Common related symptoms include acne, body or facial hair growth and accelerated hair loss in those predisposed to male pattern baldness. In the case of Winstrol, itís already a DHT compound. Fortunately, the structure of the Stanozolol hormone has been altered to reduce its androgenic effects, thereby, offering significant protection from the related side effects. They are still possible, but moderate use will keep most in the clear.

∑ Hepatotoxicity: As a C17-aa anabolic steroid, Winstrol does present toxicity to the liver. Liver enzyme values will increase with use. The more you use and the longer you use will affect the extent of the stress placed on the liver. Enzyme values increasing are not a direct sign of liver damage, but rather a general indicator of stress. Those who supplement responsibly will find their values return to normal shortly after use is discontinued assuming their liver was healthy to begin with. You should not supplement with Winstrol if your liver isnít healthy. You should also avoid excess alcohol consumption when using Winstrol. Avoiding all alcohol would be best. You should also limit the use of over the counter medications to when only absolutely necessary due to their often extreme hepatotoxic natures.

∑ Cardiovascular: Winstrol can have a significant negative impact on cholesterol levels increasing LDL and decreasing HDL. You should not supplement with this steroid if you already have high cholesterol. If youíre healthy enough for use, you will need to put some effort into controlling your cholesterol levels. A healthy lifestyle is generally the best place to start. Most are encouraged to consume plenty of omega fatty acids, as this can greatly improve cholesterol levels.

∑ Testosterone: Winstrol will suppress natural testosterone production significantly. All men who supplement with this steroid should consider the use of exogenous testosterone in order to prevent a low testosterone condition. Testosterone production will begin again on its own once all exogenous hormones have cleared your system. Natural recovery is assuming no prior existing low level condition existed and no damage was done to the HPTA through improper practices.
