Dianabol
Also known as: Dbol, Methandrostenolone, Methandienone, Anabol
Lower numbers = closer to natural. Higher numbers = more enhanced.
Why this rating?
Dianabol is one of the most potent oral steroids with an anabolic:androgenic ratio of 90-210:40-60. Users commonly gain 10-20+ lbs in 4-6 weeks (though much is water). The dramatic and rapid transformation in strength and size is impossible to replicate naturally. Its historical use by Golden Era bodybuilders to build physiques far beyond natural limits cements its status as heavily enhanced. The visible bloating and rapid gains are unmistakable markers of use.
Overview
A legendary oral steroid used for rapid "kickstarting" of mass cycles. Known for dramatic strength and size gains within the first few weeks of use.
Important Warnings
- •Liver toxic - do not exceed recommended cycle length
- •Never use without liver support
- •Must use with testosterone base
- •Do NOT stack with another 17-alpha-alkylated oral (Anadrol, Winstrol, Superdrol), liver toxicity compounds
Purpose & Use Cases
Cycle Kickstart
Used in the first 4-6 weeks of a cycle while waiting for longer-estered injectables to saturate.
Rapid Mass Gains
Provides quick and dramatic increases in weight and strength.
Strength Spikes
Produces significant strength increases, often within the first week.
Benefits
- Rapid weight and strength gains
- Dramatic increase in muscle glycogen
- Enhanced protein synthesis
- Quick results (noticeable within days)
- Improved recovery
- Increased confidence and well-being
Good to Know
A lot of the fast "gains" are water and glycogen
Dianabol's dramatic first-weeks weight jump is largely intracellular water and glycogen plus real tissue. Much of the scale weight drops when the oral is removed, only the myonuclear/lean portion persists. Judge it by strength and retained size, not day-3 bodyweight.
It genuinely needs an AI. The estrogen it makes is potent
Even though Dianabol aromatizes at a reduced rate, the estrogen it produces (17-alpha-methylestradiol) is potent and resistant to breakdown, so bloat and gyno risk are real. Run an AI dosed to bloodwork and keep a SERM on hand. This is one of the compounds where estrogen guidance genuinely applies.
17-alpha-alkylated: liver and short cycles matter
As a 17aa oral, Dbol strains the liver; keep runs to 4-6 weeks, use TUDCA/NAC, avoid alcohol, and never stack it with another 17aa oral. Liver support helps but does not make it safe.
Not a DHT-derivative: finasteride is largely irrelevant
Because Dianabol is testosterone-derived and barely contributes DHT-type androgen, finasteride does little for it. Hair impact is more estrogen/androgen-mediated than scalp-DHT-mediated.
Dosage Guidelines
| Experience Level | Dosage Range |
|---|---|
| Beginner | 20 – 30 mg/day |
| Intermediate | 30 – 40 mg/day |
| Advanced | 40 – 50 mg/day |
Do not exceed 6 weeks due to hepatotoxicity. Always use with injectable testosterone base.
Side Effects
Hepatotoxicity
very commonSignificant liver stress as a 17-alpha-alkylated oral steroid.
TUDCA 500mg daily; limit cycle to 4-6 weeks; avoid alcohol.
Extreme Water Retention
very commonHeavy water retention and bloating due to high aromatization.
Aromatase Inhibitor essential; manage sodium intake.
High Estrogen Conversion
very commonConverts to a potent, metabolism-resistant estrogen (17-alpha-methylestradiol) even at a reduced conversion rate, leading to gynecomastia risk and mood swings.
AI required (Anastrozole or Aromasin). Have SERM on hand.
High Blood Pressure
commonBlood pressure elevation from water retention and increased blood volume.
Monitor BP regularly; control sodium and estrogen.
Back Pumps
commonPainful lower back pumps during exercise.
Taurine 3-5g daily; adequate hydration.
General Mitigation Strategies
TUDCA (500mg daily) for liver protection. Aromatase Inhibitor for estrogen control. Taurine for back pumps. Keep cycles short (4-6 weeks max). Regular bloodwork for liver values.
Support Supplements
Ancillary supplements commonly run alongside Dianabol to manage side effects, support the target tissue, or fill nutrient demands it creates.
Liver support (TUDCA + NAC)
KeyDianabol is 17-alpha-alkylated and hepatotoxic. TUDCA supports bile flow; NAC replenishes hepatic glutathione. These support the liver but do not make the oral "safe". Dose/duration limits and bloodwork are the real protection.
- Dose
- TUDCA 500-1,000mg/day; NAC 600-1,200mg/day
- Timing
- Through the oral portion of the cycle
Aromatase inhibitor (anastrozole / exemestane)
KeyDianabol aromatizes to a potent, metabolism-resistant estrogen, driving water retention and gyno risk. An AI controls it; keep a SERM (tamoxifen) on hand for early gyno.
- Dose
- Anastrozole 0.25-0.5mg EOD, dosed to bloodwork
- Timing
- Through the Dbol period
- When
- Dose to E2 symptoms/bloodwork: crashing estrogen brings its own joint, mood and libido problems.
Taurine + blood pressure support
Taurine helps the back/muscle pumps Dbol is known for; telmisartan/tadalafil manage the blood-pressure rise from water retention.
- Dose
- Taurine 3-5g/day; telmisartan 20-40mg/day if BP is high
- Timing
- Daily
Post Cycle Therapy (PCT)
Standard PCT required. Can start 1-2 days after last dose due to short half-life (if run alongside an injectable base, PCT timing is dictated by that compound's ester instead).
How It Works
Dianabol increases protein synthesis and glycogenesis significantly. It enhances nitrogen retention and provides rapid increases in muscle glycogen, creating a "full" appearance. Its aromatization rate is actually lower than testosterone's, but the resulting 17-alpha-methylestradiol is potent and metabolism-resistant, so estrogenic effects (bloat, gyno risk) are still pronounced.
Hormonal & Androgenic Profile
90-210:40-60 (methandienone): strongly anabolic with moderate androgenicity
Aromatizes to 17-alpha-methylestradiol (a potent, metabolism-resistant estrogen) so despite a partly reduced conversion rate it produces heavy estrogenic bloat and gyno risk. An AI (anastrozole/exemestane) is genuinely needed, with a SERM on hand.
Dianabol is a testosterone derivative, not a DHT-derivative. Its 5-alpha-reduced metabolite is a very weak androgen, so finasteride/dutasteride do little here. Its sides are driven more by estrogen than by scalp DHT.
Raises blood pressure via heavy water retention and increased blood volume, and worsens lipids as a 17aa oral. Estrogenic bloat is prominent, much of the scale-weight is water.
Fundamentals

Common Stacks
- Dianabol + Testosterone - Classic mass building kickstart
- Dianabol + Testosterone + Deca - Old school mass stack
Detection Times
Standard urine testing typically detects metandienone metabolites for roughly 4-6 weeks after last use. WADA-accredited labs also test for longer-lived metabolites (e.g., a 17-epimeric/hydroxymethyl metabolite) that can extend the detectable window beyond that in some cases; exact timing is dose/duration and lab-method dependent.
Legal Status
Schedule III controlled substance (USA).
Legal status varies by country and changes over time. This is a general summary, not legal advice.
WADA Status
Methandienone (Dianabol) is explicitly prohibited as an anabolic androgenic steroid.
