Anadrol vs Dianabol: side-by-side comparison

Anabolic Steroid

Oxymetholone · A-bombs · A50

One of the most powerful oral anabolic steroids ever created, with an anabolic rating of 320 (vs testosterone at 100). Originally developed to treat anemia and muscle-wasting diseases. Known for producing rapid, dramatic gains in size and strength, but with significant side effects including unique estrogenic effects despite being a DHT derivative.

AnadrolDianabol
BulkingPerformance

Run for

Rapid Mass GainsCan produce 20-30+ lbs of weight gain in the first cycle, though significant portion is water retention.
Strength IncreasesProvides dramatic strength gains, making it popular among powerlifters for competition prep.
Cycle KickstartCommonly used for first 4-6 weeks while waiting for injectable steroids to reach peak blood levels.
Medical UseFDA-approved treatment for severe anemia due to its powerful effect on erythropoietin and RBC production.

Documented upside

  • Extremely rapid weight and strength gains
  • Massive increases in red blood cell production
  • Strong anti-catabolic effects
  • Joint lubrication from water retention
  • Dramatic "full" muscular look

Run for

Cycle KickstartUsed in the first 4-6 weeks of a cycle while waiting for longer-estered injectables to saturate.
Rapid Mass GainsProvides quick and dramatic increases in weight and strength.
Strength SpikesProduces significant strength increases, often within the first week.

Documented upside

  • Rapid weight and strength gains
  • Dramatic increase in muscle glycogen
  • Enhanced protein synthesis
  • Quick results (noticeable within days)
  • Improved recovery

What sticks
Semi-permanent

Anadrol

Standard PCT with Nolvadex (40/40/20/20) or Clomid (50/50/25/25). Can begin PCT 24-48 hours after last dose given its short (commonly cited ~8-9 hour, though not rigorously established) half-life.

Dianabol

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).

Read-out

How they separate

  1. 01

    Enhancement

    They land at almost the same point on the natty scale (9/10 vs 9/10): a similar distance beyond natural.

  2. 02

    Body load

    The widest gap at typical protocols is kidney load (Anadrol 5.5/10 vs 2.8/10), then blood thickness (Anadrol 7.8/10 vs 5.5/10).

  3. 03

    Coming off

    Both suppress natural testosterone production: coming off either means a recovery phase, not just stopping.

  4. 04

    Tested athletes

    Both are WADA-prohibited: neither belongs anywhere near tested competition.
