Overview
Anadrol is an oral anabolic-androgenic steroid. 17-alpha-alkylated oral DHT derivative. As a 17-alpha-alkylated compound, it passes through the liver intact, enabling oral bioavailability.
With a half-life of ~9 hours, Anadrol requires daily administration in most observed protocols. Taken orally, it has a bioavailability of approximately 95% via its primary route.
Half-life approximately 9 hours. Does not undergo direct aromatization but exhibits estrogenic activity through non-aromatase pathways. One-compartment model.
Mechanism of Action
Anadrol's pharmacological activity involves the following key pathways:
Androgen Receptor Binding
Anadrol 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
Anadrol does not undergo direct aromatization to estrogen, a distinguishing property among oral anabolics.

Frequently Asked Questions
What is Anadrol and how does it work?
Anadrol (oxymetholone) is a potent oral anabolic steroid derived from dihydrotestosterone (DHT). It was originally developed to treat anemia and muscle-wasting conditions. Oxymetholone has an exceptionally high anabolic potency and promotes significant increases in red blood cell production, protein synthesis, and nitrogen retention, resulting in rapid mass and strength gains.
What is the half-life of Anadrol?
Oxymetholone has an elimination half-life of approximately 8–9 hours. This means split dosing – typically twice daily, spaced 8–12 hours apart – is commonly observed to maintain more consistent blood concentrations. Steady-state plasma levels are generally reached within approximately 2 days of consistent dosing.
Does Anadrol aromatize into estrogen?
As a DHT derivative, oxymetholone does not convert to estrogen via the aromatase enzyme. However, it is uniquely associated with estrogenic effects such as water retention and, in rare cases, gynecomastia. This is believed to occur through direct binding to and activation of estrogen receptors, rather than through aromatization. Because aromatase inhibitors do not address this mechanism, SERMs are the relevant class of compounds for managing these effects.
How quickly does Anadrol produce results?
Anadrol is one of the fastest-acting oral anabolic steroids. Increased strength, muscle fullness, and enhanced training capacity are commonly reported within the first week. Significant weight gain – often 10–20 pounds in 4–6 weeks – is frequently observed, though a portion of this is attributable to water retention. Peak effects are generally reported around weeks 2–3 of use.
Why are Anadrol cycles kept short?
As a C17-alpha-alkylated oral steroid, oxymetholone places significant strain on the liver during use. Elevated liver enzymes (ALT, AST) are commonly observed, and prolonged use increases cumulative hepatic exposure. Cycle lengths of 4–6 weeks are the most frequently reported practice. Anadrol is often used as a short-term kickstart alongside longer injectable cycles rather than as a standalone compound.
What bloodwork should be monitored during an Anadrol cycle?
Liver function tests (ALT, AST, GGT, bilirubin) are the primary markers to monitor given the significant hepatic load of oxymetholone. A complete blood count (CBC) is also relevant, as oxymetholone was originally developed to stimulate red blood cell production and can elevate hematocrit and hemoglobin levels. Lipid panels and blood pressure monitoring are also commonly observed practice during use.
