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.

Notes

Side Effects

Hepatotoxicity

very common
Severity
4/5

Significant liver stress as a 17-alpha-alkylated oral steroid.

Mitigation

TUDCA 500mg daily; limit cycle to 4-6 weeks; avoid alcohol.

Extreme Water Retention

very common
Severity
3/5

Heavy water retention and bloating due to high aromatization.

Mitigation

Aromatase Inhibitor essential; manage sodium intake.

High Estrogen Conversion

very common
Severity
4/5

Converts to a potent, metabolism-resistant estrogen (17-alpha-methylestradiol) even at a reduced conversion rate, leading to gynecomastia risk and mood swings.

Mitigation

AI required (Anastrozole or Aromasin). Have SERM on hand.

High Blood Pressure

common
Severity
3/5

Blood pressure elevation from water retention and increased blood volume.

Mitigation

Monitor BP regularly; control sodium and estrogen.

Back Pumps

common
Severity
2/5

Painful lower back pumps during exercise.

Mitigation

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)

Key

Dianabol 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)

Key

Dianabol 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)

⚠️PCT Required

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.

Anabolic : Androgenic ratio

90-210:40-60 (methandienone): strongly anabolic with moderate androgenicity

Estrogen control

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.

DHT / 5-AR & finasteride

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.

Cardiovascular impact

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

Urine Detection
5 weeks

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.
