Superdrol Dosage Calculator
Quick answer: A 20 mg daily dose split into 2 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. Aromatises: No. Liver-strain (17α-alkylated): Yes. Half-life: Not reliably established.
About this calculator
Superdrol (methasterone) is a potent oral, non-esterified anabolic steroid — every milligram is active drug. This calculator converts a daily dose into tablets per dose. Its half-life is not reliably established, so we show no timeline rather than repeat an uncited figure.
Methasterone is a methylated DHT derivative that began as a designer/prohormone, so there is no pharmacy standard — gray-market tablets were typically 10 mg. Because it is non-esterified, only dose and tablet strength are needed.
How the tablet maths works
There is no ester — a 10 mg tablet is 10 mg of methasterone. 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: 20 mg · Tablet: 10 mg · Doses/day: 2
10 mg/dose → 10 ÷ 10 = 1 tablet(s) per dose
Daily dose: 10 mg · Tablet: 10 mg · Doses/day: 1
10 mg/dose → 10 ÷ 10 = 1 tablet(s) per dose
Superdrol 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
Active-hormone composition. A decay curve is omitted because Superdrol’s half-life is not established in any peer-reviewed source — we don’t chart numbers we can’t cite.
Methasterone has no approved-drug pharmacokinetics; the "8–12 hour" half-life seen online comes from an uncited table, so we omit a timeline. Urinary metabolites are detectable for roughly three to ten days.
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
Methasterone does not aromatise. It is 17α-alkylated and strongly hepatotoxic, with multiple published case reports of liver injury — it is one of the harsher orals on the liver, so monitoring matters.
Common mistakes
Treating Superdrol like a mild oral is the dangerous error — milligram for milligram it is potent and notably hepatotoxic. The tablet maths is simple; the risk profile is not.
Superdrol at a glance
| Property | Superdrol |
|---|---|
| Form | Oral |
| Active fraction | 1.00 (no ester) |
| Half-life | Not reliably established — the quoted "~8–12 h" is from an uncited table |
| Aromatises | No — a DHT derivative, not an aromatase substrate. |
| Liver (17α-alkylated) | Yes — 17α-alkylated, with well-documented hepatotoxicity. |
| Approx. detection | ~3–10 days (urinary metabolites). |

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.
