Anavar (Oxandrolone): A Complete Guide to Performance, Safety, and Results
If you’ve spent any time on bodybuilding forums, you’ve heard the hype: Anavar is often hailed as the “safest oral steroid.” But does it live up to that reputation? Is it really the perfect compound for cutting, recomposition, or even for women? And what are the real risks, beyond the gym bro chatter?
This deep-dive guide gives you the real story on Anavar—how it works, how to use it effectively, and how to avoid the mistakes that ruin physiques and hormonal health. Whether you’re a first-time user or a seasoned veteran, this is your complete Anavar reference.
🔬 What Is Anavar?
Anavar is the brand name for Oxandrolone, a synthetic oral anabolic steroid developed in 1962 by Searle Laboratories (now part of Pfizer). It was originally intended to treat muscle-wasting conditions, severe burns, osteoporosis, and anemia due to its unique ability to promote lean tissue growth with very low androgenic side effects.
Unlike most other steroids, Anavar is non-aromatizing (meaning it doesn’t convert to estrogen), making it ideal for users who want strength and definition without puffiness, gynecomastia, or water retention.

🧬 How Anavar Works: Mechanism of Action
Anavar’s impact goes far beyond what many expect from a so-called “mild” oral.
Here’s what it does at the cellular level:
-
Binds strongly to the androgen receptor (AR) — promoting protein synthesis and muscle regeneration
-
Increases nitrogen retention — helping the body stay in an anabolic state
-
Boosts red blood cell production — improving oxygen delivery, stamina, and vascularity
-
Enhances mitochondrial activity — contributing to greater energy efficiency and fat oxidation
-
Does NOT aromatize — zero estrogenic side effects
In addition, Anavar doesn’t significantly suppress appetite (unlike Tren or Dianabol), which makes it ideal for cutting or recomposition phases.
🧪 Clinical Use vs Bodybuilding Use
| Effect | Medical Use | Bodybuilding Use |
|---|---|---|
| Muscle Gain | Muscle-wasting conditions | Lean, dry gains |
| Fat Loss | Burn recovery, wound healing | Cosmetic fat loss with muscle retention |
| Strength | Mild improvement in rehab patients | Strong performance enhancement |
| Water Retention | None | None |
| Estrogen Conversion | None | None |
🧠 Anavar for Men: Dosage, Cycles, and Strategy
Typical Dosages for Men:
| Goal | Dosage (Daily) | Cycle Length |
|---|---|---|
| Beginner Cutting | 30–50 mg | 6–8 weeks |
| Recomp/Lean Bulk | 40–60 mg | 6–8 weeks |
| Advanced Strength | 60–80 mg | 4–6 weeks max |
Note: Due to liver stress, avoid exceeding 8 weeks. Split doses (AM/PM) for better stability.
Week-by-Week Results Timeline:
| Week | Expected Effects |
|---|---|
| 1–2 | Increased tightness, slight vascularity boost |
| 3–4 | Visible fat loss, more hardness, better pumps |
| 5–6 | Strength gains, dry look, libido may fluctuate |
| 7–8 | Plateauing gains, some suppression signs appear |
👩 Anavar for Women: Doses, Benefits & Risks
Anavar is one of the very few anabolic steroids that can be used by women with a relatively low risk of virilization—if dosed appropriately.
Typical Dosages for Women:
| Goal | Dosage (Daily) | Cycle Length |
|---|---|---|
| Physique Toning | 5–10 mg | 4–6 weeks |
| Athletic Performance | 10–15 mg | 4–6 weeks |
| Bikini Contest Prep | 5 mg + GH fragment | 6–8 weeks |
Virilization Risk Increases With:
-
Doses >15 mg/day
-
Cycles longer than 6 weeks
-
Combining with other AAS
💥 Stacking Anavar: What Works Best?
Cutting Stack (Men):
-
Anavar: 40–50 mg/day
-
Winstrol: 30 mg/day
-
Testosterone Propionate: 100 mg EOD
-
Arimidex (optional): 0.25 mg EOD
Lean Bulk Stack:
-
Anavar: 50 mg/day
-
Testosterone Enanthate: 400 mg/week
-
Equipoise or Primo: 400–600 mg/week
Beginner Stack:
-
Anavar: 30 mg/day
-
Testosterone Cypionate: 200–300 mg/week
🧫 Bloodwork During and After Anavar Cycles
Monitoring health is non-negotiable. Anavar is mild—until it’s not.
Recommended Labs:
| Marker | Why It Matters |
|---|---|
| ALT / AST | Liver enzymes — oral steroids elevate them |
| Lipid Panel | Anavar reduces HDL, raises LDL |
| Total & Free Testosterone | Suppression begins ~week 3 |
| CBC | RBC count, hematocrit changes |
Use NAC (1200–2400mg), TUDCA (250–500mg), and omega-3s to support liver and lipid health.
🧬 Post Cycle Therapy (PCT)
While Anavar isn’t as suppressive as Tren or Deca, it still shuts down natural test production. PCT is essential—especially after 6+ weeks or higher doses.
PCT Options (Men):
| Protocol | Duration | Dosage |
|---|---|---|
| Nolvadex Only | 4 weeks | 40/40/20/20 mg |
| Clomid Only | 4 weeks | 50/50/25/25 mg |
| Nolva + Clomid | 4 weeks | 20 + 25 mg daily |
PCT for Women:
Usually not needed. Instead, take 6–8 weeks off to allow hormonal reset.
🧪 Anavar vs Other Popular Compounds
| Compound | Water Retention | Suppression | Estrogenic | Ideal Use | Potency (Muscle) | Liver Toxicity |
|---|---|---|---|---|---|---|
| Anavar | None | Mild–Moderate | No | Cutting/Recomp | Moderate | Mild |
| Winstrol | None | Moderate | No | Contest prep | High (dry look) | Moderate |
| Dianabol | High | High | Yes | Bulking | High | High |
| Superdrol | None | Severe | No | Explosive strength | Extreme | Very High |
| Ostarine | None | Low | No | First-time SARM | Mild | None |
⚠️ Side Effects of Anavar
Although Anavar is among the safest steroids, side effects still occur—especially with improper use.
Common Side Effects:
-
Testosterone suppression

Mild liver stress
-
Changes in cholesterol (↓HDL, ↑LDL)
-
Acne, oily skin (rare)

Irregular menstrual cycle
These typically appear at >15mg/day or >6 weeks usage.
📚 Clinical Studies & Real-World Case Data
-
Burn Recovery – Oxandrolone reduced protein catabolism and improved muscle retention in trauma patients. [PMID: 12672062]
-
Liver Toxicity – Liver enzyme elevation is reversible post-cycle. [PMID: 20555266]
-
Women’s Use – 10mg/day for 6 weeks showed lean mass gain with minimal side effects. [PMID: 10404534]
-
Lipid Impact – Significant HDL drop at 40mg/day in healthy men. [PMC3520862]
🧠 Psychological Effects & Libido
Unlike compounds like Tren, Anavar rarely causes emotional instability. However, libido can fluctuate:
-
During cycle: Often improved due to DHT-like androgenic effect
-
After cycle: May dip due to suppressed endogenous testosterone
Support protocols (tongkat ali, ashwagandha, maca) can help during transition.
