Anadrol Dosage Calculator
Quick answer: A 50 mg daily dose split into 1 from 50 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. Aromatises: No (a DHT derivative, not an aromatase substrate). Liver-strain (17α-alkylated): Yes. Half-life: Not reliably established.
About this calculator
Anadrol (oxymetholone) is a strong oral, non-esterified anabolic steroid — every milligram is active drug. This calculator converts a daily dose into tablets per dose. Its elimination half-life is officially unknown, so we show no timeline rather than repeat an uncited figure.
Oxymetholone is one of the most potent oral steroids and is supplied by the FDA as 50 mg Anadrol-50 tablets. Because it is non-esterified, the calculator only needs dose and tablet strength.
How the tablet maths works
There is no ester — a 50 mg tablet is 50 mg of oxymetholone. The calculator divides your daily dose by tablet strength and the number of 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: 50 mg · Tablet: 50 mg · Doses/day: 1
50 mg/dose → 50 ÷ 50 = 1 tablet(s) per dose
Daily dose: 100 mg · Tablet: 50 mg · Doses/day: 2
50 mg/dose → 50 ÷ 50 = 1 tablet(s) per dose
Anadrol dose chart
Common doses at 50 mg tablets, split twice daily (each row is the calculator’s arithmetic worked out):
| Daily dose | Tablet | Doses/day | Tablets/dose |
|---|---|---|---|
| 25 mg | 50 mg | 2 | 0.25 |
| 50 mg | 50 mg | 2 | 0.5 |
| 75 mg | 50 mg | 2 | 0.75 |
| 100 mg | 50 mg | 2 | 1 |
| 125 mg | 50 mg | 2 | 1.25 |
| 150 mg | 50 mg | 2 | 1.5 |
Half-life & clearance
Active-hormone composition. A decay curve is omitted because Anadrol’s half-life is not established in any peer-reviewed source — we don’t chart numbers we can’t cite.
Unusually, oxymetholone’s elimination half-life is listed as unknown in both the FDA Anadrol-50 label and Mosby’s drug reference, so we deliberately omit a timeline. The commonly quoted "8–9 hours" has no authoritative source.
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.
Aromatisation, liver & monitoring
Oxymetholone does not aromatise, yet it still produces marked estrogen-like effects through a non-aromatase pathway, so anti-aromatase drugs do not fully control them. It is 17α-alkylated and notably hepatotoxic — liver monitoring is important.
Common mistakes
Assuming "doesn’t aromatise" means "no estrogenic sides" is the dangerous misconception with Anadrol — it is strongly estrogenic by a different route. The tablet maths, meanwhile, is trivial.
Anadrol at a glance
| Property | Anadrol |
|---|---|
| Form | Oral |
| Active fraction | 1.00 (no ester) |
| Half-life | Not reliably established — the FDA label and Mosby’s state the half-life is unknown |
| Aromatises | No (a DHT derivative, not an aromatase substrate) — but clinically estrogenic via a non-aromatase mechanism. |
| Liver (17α-alkylated) | Yes — 17α-alkylated, with documented hepatotoxicity. |
| Approx. detection | Glucuronide metabolite ~4 days; complex metabolites extend the practical window to weeks. |

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.
