Winstrol (Stanozolol)

Winstrol is the common brand name for the anabolic-androgenic steroid (AAS) Stanozolol.

Here is a detailed explanation based on your questions:

Winstrol (Stanozolol): Detail/Different Name

• Chemical Name: Stanozolol

• Brand Names (Common): Winstrol, Winstrol Depot (injectable), Stromba, Stanabol, Stanol, and others.

• Classification: It is a synthetic derivative of dihydrotestosterone (DHT), a potent natural androgen.

• Structure: Stanozolol is a 17-alpha-alkylated compound, meaning it has been chemically modified at the 17th carbon position to allow it to survive first-pass metabolism in the liver when taken orally. This modification, while making it orally active, also contributes to its liver toxicity (hepatotoxicity).

• Forms: It is available in both oral tablets and an injectable, aqueous (water-based) suspension (Winstrol Depot).

Benefits (Pros) and Side Effects (Cons)

Dosage and Frequency

Stanozolol is a controlled substance and is banned by major sports organizations (WADA). The following dosages reflect typical usage in performance-enhancing contexts, not medical recommendations. Dosage should only be determined by a qualified medical professional for approved therapeutic uses.

• Oral (Tablets): Common doses for physique enhancement typically range from 25 mg to 50 mg per day. Due to its relatively short half-life and C17-alpha alkylation, oral doses are often split throughout the day (e.g., morning and evening) to maintain stable blood levels.

• Injectable (Winstrol Depot): Common doses range from 50 mg every day or every other day (EOD). The suspension form has a slower release than the oral compound but is still administered frequently.

• Medical Dosage (for HAE): Initial dose is typically 2 mg orally, three times a day. The maintenance dose is often decreased to 2 mg daily over time.

Half-Life and Detection Time

Note on Detection Time: These times are estimates. The actual detection time depends heavily on the specific drug test (urine, blood, hair), individual metabolism, dosage, and duration of use. Stanozolol is metabolized into unique compounds (metabolites) that are detectable for a significant time after the parent drug is cleared, especially a primary metabolite called 3'-hydroxystanozolol. Hair tests can potentially detect use for up to 12 months.

Sterogenic, Progestrogenic, and Prolactin Effects

• Estrogenic (Sterogenic) Effects:

  • Effect: Zero/None. Stanozolol is a DHT-derivative and cannot be converted into estrogen by the aromatase enzyme.

  • Clinical Relevance: Users do not experience estrogen-related side effects like gynecomastia or significant water retention.

• Progestrogenic Effects:

  • Effect: Zero/None of significance. Stanozolol does not exhibit significant binding affinity for the progesterone receptor (PR).

  • Clinical Relevance: It is not associated with progesterone-related side effects.

• Prolactin Effects:

  • Effect: Indirect/None. Stanozolol is not known to directly increase prolactin levels.

  • Clinical Relevance: Prolactin-related side effects (such as lactation/galactorrhea, often associated with compounds that are progestins) are not typical for Stanozolol use.

Anabolic Androgenic Ratio

The ratio is a comparison of the drug's anabolic (muscle-building) effects to its androgenic (masculinizing) effects, compared to testosterone (which is standardized at 100:100).

• Anabolic Androgenic Ratio (Stanozolol): Approximately 300:30 to 300:100 (depending on the source and measurement method).

• Simplified Digits (Ratio of Anabolic:Androgenic): 3:1 to 10:1 (e.g., 300 to 30 or 300 to 100). The most frequently cited raw figure in the scientific literature is 30:1.

• The Number: 30:1

This ratio indicates that Stanozolol has a much higher potential for building tissue than for producing strong masculinizing side effects, though the androgenic effects are still significant, especially at high doses.
