Kalpa Pharmaceuticals Stanoxyl


Stanoxyl is the brand and trade name for the anabolic steroid Stanozolol offered to the market by Kalpa Pharmaceuticals. It is also informally known in slang terms as winny.

It was among the first handful of anabolic steroids created and fast became one of the most popular compounds in use today. Stanoxyl’s popularity is perhaps in the 3rd place among anabolic steroid popularity and use, landing behind Deca-Durabolin and Dianabol.

Unline Deca and Dianabol, WInstrol’s immense popularity did not rise significantly until the 1980s, and especially into the 1990s. The reason for the surge in popularity after 1990 was because of the alleged use of Winstrol by Canadian Olympic sprinter Ben Johnson in the 1988 summer Olympics, which he had supposedly tested positive for.

The origins of Winstrol date back much further, however. In 1959, Stanozolol’s details were first published, and it was not long at this time until Winthrop Laboratories in Great Britain began to manufacture the drug.

Shortly afterwards into the 1960s, Sterling Laboratories in the USA obtained the patent for manufacture, and Stanzolol was then manufactured and marketed on the prescription drug market as Winstrol.

Its approved uses in medicine skyrocketed after this, with its use ranging from appetite stimulation to muscle wasting disorders and diseases.

Over the years, Winstrol’s manufacturing and marketing had shifted and changed hands, with patents currently being held in the USA by Ovation Pharmaceuticals, however none is officially currently manufactured in the USA at this time.

Internationally, it is still manufactured by many different pharmaceutical companies and there are abundant numbers of generic as well as brand name Winstrol products.

Stanoxyl is a very popular compound among bodybuilders and athletes for its ability to promote lean mass without the massive bulk and water retention that is sometimes unwanted.

It can further enhance the ‘ripped’ look of a physique when the body is at low enough body fat levels, unlike other anabolic steroids like Dianabol that tend to put water retention on to the user, and therefore a soft look on the physique.

Stanoxyl, due to its modifications and its nature as a DHT-derivative, is unable to convert into Estrogen at any dose. It also expresses an anabolic:androgenic ratio of 320:30, making it 3.2 times stronger in terms of muscle growth and anabolism than Testosterone itself. It is also theoretically much less androgenic than Testosterone as well.

Kalpa Pharmaceuticals Stanoxyl is available in both an oral form, coming in 10 mg and 50 mg pills, as well as an water based injectable suspension know as Stanoxyl Depot.

Side Effects

Being that Stanoxyl is a DHT-derivative that cannot convert into Estrogen at any dose at all, Estrogen-related side effects are not a concern from Stanoxyl alone.

The main concerning Stanoxyl side effects relate to its nature as a C17-alpha alkylated compound, and the fact that it can be more androgenic than theoretically noted.

It does carry with it all of the other typical and common side effects that all anabolic steroids share as well (such as HPTA shutdown, cardiovascular concerns, cholesterol alterations, etc.).

Potential liver toxicity (hepatotoxicity) is one of the more concerning Stanoxyl side effects, especially if the oral variant of Stanozolol is being used.

This means that individuals should limit their use of oral Stanoxyl to no longer than 4 – 6 weeks.

Androgenic Stanozolol side effects can be a concern as well, as although its androgenic rating is much less than that of Testosterone, many individuals have reported problems with acne, male pattern baldness, and oily skin, etc.


The symptoms of an overdose of Stanoxyl are not know. Though it is unlikely for an overdose of Stanoxyl to put life at risk, one should seek immediate medical help or advice if they suspect an overdose.

Do not raise the dosage without instructions to do so from your doctor. Do not double the Stanoxyl dose if a previous dose has been missed. Take the missed dose immediately as you recall about it.

In case you’re close to taking the next recommended dose, you should skip the missed one and follow the treatment plan further according to the schedule.



Anabolic steroids can potentiate the effects of anticoagulants. Stanoxyl is an anabolic steroid therefore, the PT (prothrombin time) should be checked when anabolic steroids and anticoagulants are administered at the same time, and the dose of the anticoagulants should be adjusted if necessary.


Patients taking insulin may need a dose adjustment of the insulin if the use of anabolic steroids is started or concomitent anabolic steroid therapy is stopped. Anabolic steroids can lower blood glucose and thus require a reduction in insulin dose.


Kalpa Pharmaceuticals Stanoxyl is an oral anabolic steroid that can cause severe side effects. Talk to your doctor before taking it. Oral Stanozolol is a 17-alpha-alkylated anabolic androgenic steroid.

The 17-alpha-alkylation is associated with a higher rate of hepatotoxicity and can cause irreversible liver damage if misused, thus liver function tests are recommended on a regular basis.


As previously noted, Stanoxyl is normally used in conjunction with other anabolic steroids.

This can be for several different reasons, one of which is its synergistic capabilities in allowing other anabolic steroids (especially Testosterone) to be much more effective.

This is achieved through its ability to prevent SHBG (Sex Hormone Binding Globulin) in the body from acting upon Testosterone or other anabolic steroids.

As such, some anabolic steroid users might run Stanoxyl cycles with two other compounds, or sometimes three other compounds.

Beginner Stanoxyl cycles normally involve a basic stack of Stanoxyl stacked with Testosterone (usually a long ester, such as Enanthate).

This allows the beginner to get a feel for the compound without too much interference from other compounds.

An intermediate Winstrol cycle would be either the addition of another compound with Testosterone, such as Deca-Durabolin, or merely the use of Testosterone at a low TRT dose of something like 100mg/week in order to emphasize Winstrol’s capabilities more.

Advanced Winstrol cycles can include 2 or 3 other compounds stacked with Stanoxyl, such as Trenbolone Acetate and Testosterone Propionate.

This is common among competing bodybuilders as a pre-contest stack.
