Overview
Superdrol is an oral anabolic-androgenic steroid. 17-alpha-alkylated methylated drostanolone derivative. As a 17-alpha-alkylated compound, it passes through the liver intact, enabling oral bioavailability.
With a half-life of ~8 hours, Superdrol requires daily administration in most observed protocols. Taken orally, it has a bioavailability of approximately 50% via its primary route.
Half-life approximately 8 hours. Oral bioavailability ~50%. One-compartment model.
Mechanism of Action
Superdrol's pharmacological activity involves the following key pathways:
Androgen Receptor Binding
Superdrol binds to androgen receptors to initiate anabolic signaling cascades in muscle tissue and other androgen-responsive cells.
17-Alpha Alkylation
The 17-alpha-alkyl group prevents first-pass hepatic degradation, enabling oral bioavailability. This structural modification is what makes oral administration viable.
Non-Aromatizing
Superdrol does not undergo direct aromatization to estrogen, a distinguishing property among oral anabolics.

Frequently Asked Questions
What is Superdrol and how does it work?
Superdrol (Methyldrostanolone, also called Methasterone) is a synthetic oral anabolic–androgenic steroid derived from Drostanolone (Masteron) with a 17α-methyl modification for oral bioavailability. It has an anabolic-to-androgenic ratio of approximately 400:20, making it one of the most potent oral anabolics by weight. As a DHT derivative, it binds directly to androgen receptors in muscle tissue to promote nitrogen retention and protein synthesis without converting to estrogen.
What is the half-life of Superdrol?
Superdrol has an elimination half-life of approximately 8–12 hours. This relatively short half-life means the compound clears the system quickly and is commonly dosed twice daily (AM and PM) to maintain more stable blood concentrations throughout the day.
What are the common dosing protocols for Superdrol?
Reported daily amounts typically range from 10–30 mg per day, taken orally. A common approach observed in community protocols is 10 mg/day for the first week, escalating to 20 mg/day for weeks two through four. Some advanced users have reported doses up to 30 mg/day, though this is less common. Cycle duration is typically kept short at 3–4 weeks.
Does Superdrol cause water retention or estrogen-related effects?
Superdrol is a non-aromatizing DHT derivative, meaning it cannot be converted to estrogen by the aromatase enzyme. This results in a characteristically dry, dense appearance without water retention or estrogen-mediated effects. The compound is frequently selected specifically for this quality when a lean, defined look is the priority.
How long does it take for Superdrol to show results?
Superdrol is a fast-acting oral compound. Strength increases and changes in muscle fullness have been reported within the first 7–10 days. Visible changes in body composition — particularly increased muscle density and vascularity — are commonly observed by the end of the second week. Full results typically manifest across the 3–4 week cycle duration.
What compounds are commonly stacked with Superdrol?
Superdrol is most commonly used alongside injectable testosterone (such as Testosterone Enanthate or Cypionate) as a cycle kickstarter during the first 3–4 weeks while longer-acting compounds build to steady state. It is generally not stacked with other 17α-alkylated oral compounds. A testosterone base is considered standard practice when running Superdrol.
