Winstrol (Stanozol)pills is a steroid derived from dihydrotestosterone dihydrotestosterone (DHT), more accurately a structurally altered form of the drug.Two structural changes on DHT create Winstrol. The first was the replacement of the pyrazol group on the A ring with the 3-keto group 3-keto group, a change that classifies Winstrol as a heterocyclic steroid heterocyclic steroid.The second change Winstrol carries on it a methyl group used for the hormone that enters the body, a structural change that occurs in the seventeenth carbon chain, classifying the drug as a C17- aa steroid.

The result of the above two structural changes is that the anabolic index of Winstrol is as high as 320 and the androgenicity index is only 20, what is more, these indexes are also excellent in practical applications, Winstrol is an anabolic steroid with great benefits.

One of the benefits of stanozolol bodybuilding is that it reduces Sex-Hormone-Binding-Globulin (SHBG) more powerfully than other steroids, which allows more of the steroid to be in a free state, increasing free testosterone levels. Studies have shown a 50% reduction in SHBG in just a few days of low-dose dosing.

Winstrol also enhances protein synthesis and nitrogen storage in muscle, increases red blood cell count, and inhibits glucocorticoids (adrenocorticotropic hormones) to some extent. And  is mild and easy to control.

Winstrol is available both as an injection and orally, with little difference in effectiveness; users report that the oral medication has been SHBG is more effective, while the injection potency is swifter, but this disparity is not significant.

Both injectable and oral Winstrol are C17-aa steroids, and most oral steroids are in this category, injectables are mostly not. The exception is injectable Winstrol (also known as Winstrol Depot).

winstrol benefits bodybuilding:

Although used to treat muscle atrophy, Winstrol is not a qualified off-season bulking steroid. Its SHBG-lowering nature can intensify the effects of other drugs, but this is not recommended. Winstrol is highly hepatotoxic and C should be used where it is most valuable, obviously for male off-season it is inappropriate, female athletes can consider Winstrol for off-season, although it is not the best choice.

Winstrol is more beneficial for physical athletic programs than bodybuilding and fitness. It can drastically improve strength and speed without adding too much muscle that is not needed for these programs. Some people point out that Winstrol is not suitable for these competitive sports because it weakens the tendons. This is not the case, as many studies have proven that Winstrol can increase bone density, otherwise why take it for osteoporosis.

For bodybuilders, Winstrol can make the body look drier and tighter, provided you already have low enough body fat. It also maintains lean body mass to some extent. It is recommended as a secondary steroid inside C rather than a base.

Some people complain of joint discomfort when using Winstrol, this steroid does not aromatize and does not store water. Often Winstrol is used pre-competition, bodybuilders at this stage have extremely low bodyfat, usually in the single digits, a level at which joints may be uncomfortable with or without the drug, in fact the very common combination of Winstrol and Nandrolone phenylpropionate can be a great solution to any joint discomfort that may exist.

In the final stages of getting out of shape, both male and female athletes can greatly benefit from Winstrol to protect lean body mass, maintain strength, and increase vascularity and line definition.

Side effects of Winstrol

winstrol cycle Dosage :

There isn’t a clear standard for how much steroid to use, and some drugs can have very large dosage ranges, such as testosterone which can range from 200 mg to 1,000 mg or even more per week. The dosage of Winstrol however does not vary too much from person to person and is simple to use and similar for all purposes.

For girth gain:

It is not a good choice for bulking, its high anabolic low androgenic nature makes it more suitable for gaining strength and shaping lines. The reduced SHBG nature allows it to assist other steroids in bulking C, but we have other better options. This is one of the few drugs that can be called a molding steroid, and 50 mg per day is enough.

For fat loss:

Winstrol is mostly used to do status, 50 mg per day for six to eight weeks, some people 100 mg per day, which is already a very high dose, increasing the stress on the liver and negatively affecting lipid metabolism. The exception is bodybuilders who are very effective at 100 mg per day for a short period of time prior to competition, and the toxicity is manageable. Many bodybuilders will continue 50 mg per day for six weeks then increase to 100 mg per day two weeks prior to competition to increase dryness.

Used in physical fitness type competitive sports:

Increasing strength without increasing girth is a hallmark of Winstrol, and the dosage for physique-dominant athletes will vary more, perhaps as low as 20-25 mg every two days. More athletes will use about 50 mg every two days, with the entire cycle typically lasting four to six weeks.

Dosage for Female Athletes:

Winstrol is one of the few steroids that can be safely used by women as well, the vast majority of doses are 10mg per day, some female bodybuilders and fitness athletes use 20mg per day, but this greatly increases the risk of androgenization, and if 10mg doesn’t work well you may need to consider if something is wrong with the rest of the C’s. Other drugs commonly used by female competitive athletes are Anavar, Primobolan Depot and many types of SERMs, thyroid hormones and growth hormones.
