Dianabol (Methandrostenolone) — Dosing, Cycles, Half-Life & Side Effects
Dianabol (Methandrostenolone) is an oral anabolic-androgenic steroid with a half-life of 3-6 hours. Classic oral steroid for rapid muscle gains. Primary risks include significant hepatotoxicity, strong HPTA suppression, liver stress typical of 17α-alkylated orals.

Typical Dosing Ranges
Common dose range: 20-50mg/day
Cycle length: 4-6 weeks
Time to steady state: ~1 days
Dose ranges are compiled from published pharmacokinetic studies and community-reported usage. Where a value is community-reported rather than clinically studied, this page and its structured data flag it. Lower end of any range is always the safer starting point.
Stacking Considerations
- Do not stack with another 17α-alkylated oral. Dual-17αα stacking is prohibited in StackItSmart and unsafe for the liver.
- Incompatible combinations per internal rule set: Anadrol (Oxymetholone), Superdrol (Methasterone).
PCT Requirements
- This compound causes clinically meaningful HPTA suppression. Post-cycle therapy is recommended.
- Depot clearance estimate: ~1 days post-last-dose before SERM start (5 × apparent depot half-life of 6h).
- Never stack two SERMs. Extend a single SERM (tamoxifen OR enclomiphene/clomiphene) rather than combining.
- Use the cycle planner to generate a full protocol based on your complete stack, not this compound alone.
Side Effect Profile
- Liver toxic
- Water retention
- Estrogen conversion
- High suppression
Known Interactions
Anavar (Oxandrolone) + Dianabol (Methandrostenolone)
major — hepatotoxicTwo oral steroids with significant hepatotoxicity. Combined liver stress is multiplicative.
Recommendation: Never combine multiple 17-alpha alkylated orals. Choose one or use with injectable.
Monitor: AST, ALT, GGT, Bilirubin
Dianabol (Methandrostenolone) + Anadrol (Oxymetholone)
major — hepatotoxicTwo of the most hepatotoxic oral steroids. Extreme liver damage risk.
Recommendation: Never combine. Both individually require careful liver monitoring.
Monitor: Full liver panel weekly

Monitoring (Bloodwork & Vitals)
- Comprehensive metabolic panel (baseline, mid-cycle, post-cycle)
- Lipid panel (total cholesterol, HDL, LDL, triglycerides)
- CBC (hemoglobin, hematocrit — watch for erythrocytosis)
- Sex-hormone panel (Total T, Free T, Estradiol sensitive, SHBG, LH, FSH)
- Liver enzymes (ALT, AST, GGT) every 2–4 weeks on oral 17αα cycles
- Blood pressure (weekly self-check; flag systolic >140 or diastolic >90)
Baseline bloodwork is recommended before any cycle. Discontinue if liver enzymes exceed 3× upper limit of normal or if hematocrit exceeds 54%.
Frequently Asked Questions
What is the half-life of Dianabol (Methandrostenolone)?
Dianabol (Methandrostenolone) has a half-life of approximately 3-6 hours. Clearance estimate: 6h � 5 = 30h = 1.25 days. This figure is used to determine injection frequency (for esters) and post-cycle clearance timing.
What is the typical dose range for Dianabol (Methandrostenolone)?
Commonly reported ranges for Dianabol (Methandrostenolone): 20-50mg/day. Cycle length: 4-6 weeks. These are compiled from published studies and community-reported usage — individual response varies and lower end is always preferred.
Does Dianabol (Methandrostenolone) suppress natural testosterone?
Dianabol (Methandrostenolone) causes severe suppression of the HPTA axis (score 10/10). Post-cycle therapy (PCT) is recommended after use.
Is Dianabol (Methandrostenolone) liver toxic?
Hepatotoxicity rating: High. Dianabol (Methandrostenolone) is 17α-alkylated, which bypasses first-pass liver metabolism and increases hepatic stress. Oral 17αα cycles should be capped at 6 weeks and paired with liver monitoring (ALT/AST every 2–4 weeks).
Does Dianabol (Methandrostenolone) aromatize to estrogen?
Aromatization profile: Yes. An aromatase inhibitor may be warranted if estrogen-related side effects appear — but AI use should be symptom-driven, not prophylactic, to avoid crashing E2.
What is Dianabol (Methandrostenolone) typically used for?
Dianabol (Methandrostenolone) is commonly used for: Bulking, Strength gains, Intermediate users. Intended-use context does not imply safety — every use case carries the same underlying pharmacological risks.
