Winstrol vs. Clostebol: History and Uses

Overview of Winstrol: History and Uses

Winstrol, chemically known as Stanozolol, is a synthetic anabolic steroid derived from dihydrotestosterone (DHT). First synthesized in the 1950s by Winthrop Laboratories, Winstrol quickly gained medical approval due to its potent anabolic properties and minimal androgenic effects.

Initially, Winstrol was prescribed for treating hereditary angioedema, a condition that causes episodes of swelling in the face, extremities, bowel wall, and genitals. Its ability to promote nitrogen retention, red blood cell production, and protein synthesis made it useful in preserving lean body mass in patients suffering from muscle-wasting conditions.

Winstrol's fame exploded in 1988 after Ben Johnson, a Canadian sprinter, tested positive for the drug following his record-breaking Olympic win in Seoul. This incident drew global attention to the use of performance-enhancing drugs (PEDs) in athletics.

“Winstrol became infamous in the sports world after Ben Johnson’s disqualification in 1988, serving as a cautionary tale about PED use.” — Llewellyn, Anabolics

Despite the negative press, Winstrol maintained popularity in bodybuilding and sports due to its ability to promote lean muscle gains, vascularity, and strength without water retention. Its versatility—being available in both oral and injectable forms—makes it accessible and appealing to a wide variety of users.

In veterinary medicine, Winstrol is used to increase appetite and muscle mass in debilitated animals, especially horses. Its muscle-preserving properties are leveraged in both human and animal health, solidifying Winstrol’s place in anabolic steroid history.

Overview of Clostebol: History and Uses

Clostebol, known chemically as 4-chloro-testosterone, is a synthetic derivative of testosterone. It was developed in the 1960s and was primarily designed to provide anabolic benefits without the intense androgenic and estrogenic side effects associated with testosterone.

In medicine, Clostebol has been used to treat conditions such as muscle-wasting diseases, severe burns, and recovery from trauma. Its relatively mild anabolic properties make it safer for long-term therapeutic use compared to stronger anabolic agents.

Unlike Winstrol, Clostebol has largely avoided high-profile doping scandals, although it remains banned by the World Anti-Doping Agency (WADA). It has nonetheless gained traction among athletes and bodybuilders seeking moderate muscle enhancement with a lower risk of side effects.

“Clostebol offers a cleaner anabolic profile, with reduced risks of aromatization or androgenic complications, making it attractive for conservative users.” — Roberts, Steroid Profiles

Clostebol is commercially available in multiple forms:

• Topical creams (e.g., Clostebol acetate)

• Injectable esters

• Oral tablets

This variety offers flexible administration routes depending on the user’s goals and comfort level.

Its use is common during cutting cycles, where the primary objective is muscle preservation rather than extreme growth. For this reason, Clostebol is often stacked with other compounds or used as a milder alternative to harsh steroids.

Benefits for Athletes and Bodybuilders

Benefits of Winstrol

Winstrol (Stanozolol) remains one of the most widely used anabolic steroids for athletes and competitive bodybuilders due to its cutting-specific benefits and performance-enhancing capabilities.

1. Lean and Dry Muscle Gains

Winstrol is prized for its ability to build lean muscle mass without water retention. Because it does not aromatize into estrogen, users typically experience a dry, hard, and vascular physique—ideal for cutting phases and pre-competition aesthetics.

“Unlike many bulking agents, Winstrol enhances muscle hardness without the bloated look associated with estrogenic compounds.” — Llewellyn, Anabolics

2. Enhanced Strength and Power

Winstrol promotes muscle protein synthesis and nitrogen retention, helping athletes gain strength and improve explosive power. It’s commonly used by sprinters, fighters, gymnasts, and weightlifters who need strength increases without excessive muscle bulk.

3. Improved Endurance and Recovery

By stimulating red blood cell (RBC) production, Winstrol improves oxygen transport to muscles, reducing fatigue and enhancing cardiovascular endurance. This supports more intense training sessions and faster recovery.

4. Minimal Weight Gain

Winstrol’s anabolic effects come without significant mass gain, which is critical for athletes in weight-class sports or those needing to maintain agility. It promotes strength-to-weight ratio improvements, making it ideal for dynamic or endurance-based disciplines.

Benefits of Clostebol

Clostebol (4-chloro-testosterone) offers moderate anabolic support with a milder side effect profile, making it particularly attractive to athletes who prioritize recovery, injury prevention, and maintenance over aggressive mass building.

1. Muscle Maintenance and Recovery

Clostebol promotes protein synthesis and protects against muscle catabolism, making it useful during high training volumes, injury rehab, or calorie deficits. It helps preserve lean mass, especially when strength training or mobility work is limited.

“Clostebol is one of the safer compounds for post-surgery recovery or during injury rehabilitation due to its mild anabolic nature.” — Roberts, Steroid Profiles

2. Mild Anabolic Support with Fewer Risks

Its low androgenic rating and resistance to aromatization mean Clostebol poses less risk of gynecomastia, acne, or hair loss. This makes it a safer entry point for beginners or those cycling off stronger compounds.

3. Boosted Endurance and Oxygen Utilization

Like Winstrol, Clostebol enhances red blood cell production, promoting better oxygen delivery to muscle tissues. This benefit makes it especially effective for endurance athletes like runners, cyclists, and swimmers, who rely on stamina and aerobic capacity.

4. Versatility in Application

Clostebol is available in oral, injectable, and topical forms, giving users flexibility in dosing and minimizing injection fatigue in long-term use cases.

Side Effects and Final Considerations: Winstrol vs. Clostebol

Potential Side Effects and Risks of Winstrol

Winstrol, while effective for cutting and strength gains, carries significant health risks—particularly when misused or taken at high doses.

1. Hepatotoxicity

Winstrol is a 17-alpha-alkylated compound, designed to survive oral ingestion. However, this also means it places substantial strain on the liver, increasing the risk of hepatotoxicity and liver enzyme elevation.

“Due to its alkylation, Winstrol presents a higher risk of liver toxicity, necessitating blood work and cycle limits.” — Llewellyn, Anabolics

Recommendation: Use liver support supplements (e.g., NAC, milk thistle) and avoid alcohol or other hepatotoxic drugs during use.

2. Negative Impact on Cholesterol

Winstrol significantly reduces HDL (good) cholesterol and raises LDL (bad) cholesterol, contributing to an increased risk of atherosclerosis, heart disease, and stroke.

Recommendation: Incorporate omega-3s, such as krill oil, and adhere to a heart-healthy diet rich in fiber and antioxidants.

3. Androgenic Side Effects

Though not as androgenic as testosterone, Winstrol can cause:

• Acne

• Hair loss (especially in genetically predisposed individuals)

• Increased body/facial hair

In women, virilization symptoms may include:

• Deepened voice

• Enlarged clitoris

• Facial hair growth

4. Testosterone Suppression

As with most anabolic steroids, Winstrol suppresses natural testosterone production, which can lead to low libido, fatigue, and mood instability post-cycle.

Post-Cycle Therapy (PCT) with compounds like Clomid (Clomiphene) or Nolvadex (Tamoxifen) is essential.

---

Potential Side Effects and Risks of Clostebol

Clostebol is considered a milder anabolic steroid, but it is not without risks, especially when used over extended periods or in high doses.

1. Endocrine Suppression

Clostebol can suppress the hypothalamic-pituitary-gonadal (HPG) axis, reducing natural testosterone production.

“Although milder, Clostebol still requires proper PCT to avoid prolonged suppression and hormonal imbalances.” — Roberts, Steroid Profiles

Symptoms of suppression may include:

• Decreased libido

• Lethargy

• Testicular atrophy

Recommendation: Always follow with an appropriate PCT protocol after a Clostebol cycle.

2. Cardiovascular Risks

While less dramatic than Winstrol, Clostebol may still:

• Lower HDL cholesterol

• Elevate LDL cholesterol

Regular lipid panel monitoring is advised, especially for users with a family history of heart disease.

3. Mild Androgenic Effects

Androgenic side effects may include:

• Oily skin

• Mild acne

• Hair thinning

The risk of virilization in women is low, but still possible depending on dosage and duration.

Post-Cycle Therapy (PCT) After Winstrol or Clostebol

Why PCT Is Essential

Both Winstrol (Stanozolol) and Clostebol suppress your body’s natural testosterone production by interfering with the hypothalamic-pituitary-gonadal (HPG) axis. Without a proper PCT, users can experience:

• Low libido

• Fatigue

• Mood swings

• Muscle loss

• Prolonged suppression of natural testosterone

Post-Cycle Therapy (PCT) helps reboot endogenous testosterone, stabilize hormone levels, and protect muscle gains.

---

PCT After Winstrol

Due to Winstrol’s moderate suppression and hepatotoxicity, a robust PCT protocol is recommended.

✅ PCT Protocol Example:

• Clomid (Clomiphene Citrate)
  50 mg/day for 2 weeks, then 25 mg/day for 2 more weeks

• OR
  Nolvadex (Tamoxifen Citrate)
  40 mg/day for 2 weeks, then 20 mg/day for 2 more weeks

✅ Start Time:

Begin PCT 1–2 days after your last oral Winstrol dose, or 3–5 days after your last injection.

✅ Add-on Support:

• D-Aspartic Acid (3,000 mg/day) — natural testosterone booster

• ZMT by Swolverine — includes zinc, magnesium, DHEA (100 mg/day), and ashwagandha to support endocrine function and deep sleep

• NAC (N-Acetyl Cysteine) — 600–1200 mg/day to support liver detox post-cycle

• Krill Oil or Omega-3s — for cholesterol support

“Clomid and Nolvadex remain the gold standards in restoring HPG axis function after a suppressive oral steroid cycle.” — Roberts, ThinkSteroids

---

PCT After Clostebol

Clostebol is milder, but it still suppresses natural testosterone. A lighter PCT is often sufficient, especially for short or low-dose cycles.

✅ PCT Protocol Example:

• Nolvadex
  20 mg/day for 2–3 weeks

• Optional Clomid
  25 mg/day for 2 weeks (only if suppression symptoms are more pronounced)

✅ Start Time:

Begin PCT 3–5 days after last injection or oral dose.

✅ Add-on Support:

• ZMT by Swolverine — enhances sleep quality, libido, and testosterone recovery

• Vitamin D3 (5000 IU/day) — shown to improve testosterone production

• Adaptogens (e.g., ashwagandha, rhodiola) — to reduce cortisol and support hormonal balance

“For milder cycles like Clostebol, shorter and gentler PCT can be effective, especially when paired with lifestyle optimization and quality supplements.” — Llewellyn, Anabolics

---

PCT Best Practices

• Blood Work: Check testosterone, LH, FSH, estradiol, and liver values pre- and post-cycle

• Sleep: 7–9 hours per night supports hormonal recovery

• Training: Reduce volume/intensity during the first 2–3 weeks of PCT

• Diet: High-protein, nutrient-dense foods to support anabolism and immunity

• Alcohol: Avoid—especially critical after oral cycles due to liver stress
