Dianabol Dosage Calculator
Quick answer: A 30 mg daily dose split into 3 from 10 mg tablets is 1 tablet(s) per dose. Tablets = (daily mg ÷ doses) ÷ mg per tablet.
Oral, non-esterified — every mg is active drug; the calculator converts dose → tablets. Aromatizes: Yes (weak/atypical). Liver-strain (17α-alkylated): Yes. Half-life: ≈ 3–6 hours (textbook consensus, often cited ~4.5–5 h).
About this calculator
Dianabol (metandienone) is an oral, non-esterified anabolic steroid — every milligram is active compound. This calculator converts a daily dose into tablets per dose, and shows the short 3–6 hour half-life that is why the dose is commonly divided across the day.
Methandienone is one of the oldest oral anabolic steroids and is non-esterified, so the calculator only converts your daily dose into tablets. Tablets are commonly 5, 10, 25 or 50 mg.
How the tablet maths works
Every milligram of a Dianabol tablet is active methandienone — there is no ester. A 30 mg day split into three 10 mg tablets is exactly 30 mg, and the calculator just divides dose by tablet strength and splits.
How to use this calculator
Enter your daily dose, your tablet strength (mg per tablet), and how many times a day you split the dose. The result updates instantly with tablets per dose and the per-dose milligrams.
Worked examples
Daily dose: 30 mg · Tablet: 10 mg · Doses/day: 3
10 mg/dose → 10 ÷ 10 = 1 tablet(s) per dose
Daily dose: 40 mg · Tablet: 25 mg · Doses/day: 2
20 mg/dose → 20 ÷ 25 = 0.8 tablet(s) per dose
Dianabol dose chart
Common doses at 10 mg tablets, split twice daily (each row is the calculator’s arithmetic worked out):
| Daily dose | Tablet | Doses/day | Tablets/dose |
|---|---|---|---|
| 5 mg | 10 mg | 2 | 0.25 |
| 10 mg | 10 mg | 2 | 0.5 |
| 20 mg | 10 mg | 2 | 1 |
| 30 mg | 10 mg | 2 | 1.5 |
| 40 mg | 10 mg | 2 | 2 |
| 50 mg | 10 mg | 2 | 2.5 |
Half-life & clearance
Illustrative single-dose elimination by half-life (t½ ≈ 0.19 days). Each marker is one half-life; after ~5 the dose is essentially cleared.
With a short ~3–6 hour half-life, blood levels rise and fall quickly, which is why daily doses are often divided. The compound clears conventionally within a few days, though a long-term metabolite is detectable for about 19 days after a single dose (Schänzer 2006).
How to interpret your result
The result is the number of tablets to take per dose. Fractions mean a tablet would need splitting — round to what your tablet strength allows. The half-life figure is a pharmacokinetic timing reference only.
Aromatization, liver & monitoring
Methandienone aromatizes to a methylated estrogen, so estrogenic effects such as water retention can appear quickly; it is also 17α-alkylated and notably hepatotoxic, making liver monitoring important on any oral run.
Common mistakes
Underestimating the liver and estrogen load is common because the dose looks small in milligrams. The tablet maths is trivial; the physiology is not.

|---|---|
| Form | Oral |
| Active fraction | 1.00 (no ester) |
| Half-life | ≈ 3–6 hours (textbook consensus, often cited ~4.5–5 h) |
| Aromatizes | Yes (weak/atypical) — converts to 17α-methylestradiol, a strongly estrogenic metabolite. |

How this is calculated
For injectables the calculator divides your weekly dose by the number of injections, then by the vial concentration, to get the mL per shot — and multiplies by 100 for U-100 syringe units (1 mL = 100 units). The active-hormone milligrams are the dose multiplied by the esterFactor (the parent hormone’s molecular weight divided by the full ester’s molecular weight, both from PubChem). For orals it divides the daily dose by your doses-per-day and tablet strength to get tablets per dose. Half-life timing uses ke = ln2 ÷ t½ and the ~5-half-life rule of thumb for steady state and clearance. It is arithmetic only — nothing you enter is stored or sent anywhere, and the result is not medical advice or an endorsement of anabolic steroid use.
