Methasterone, widely known by its colloquial name Superdrol, is a synthetic anabolic compound derived from dihydrotestosterone (DHT) with a notably unconventional research history compared to most oral anabolic steroids. Unlike the majority of compounds in CSD’s oral range which carry decades of pharmaceutical or clinical documentation, Methasterone was originally synthesized in the 1950s but never developed for pharmaceutical use, instead surfacing in the early 2000s as a designer prohormone supplement before being scheduled as a controlled substance. F40 Biotech’s formulation delivers 15mg per tablet in a 50 count format, a precisely dosed presentation consistent with the concentrations most commonly referenced in contemporary anabolic research literature.
Methasterone’s pharmacological profile is defined by an exceptionally high anabolic to androgenic ratio, estimated anabolic activity approximately four times that of Methyltestosterone with significantly reduced androgenic activity relative to its anabolic potency. As a DHT derived compound it does not aromatize, producing no estrogenic conversion regardless of dose. Methasterone is not 17 alpha alkylated in the traditional sense but carries a 2 alpha, 17 alpha dimethyl modification that confers oral bioavailability while producing a distinct hepatic metabolism pathway compared to standard alkylated oral compounds, a structural difference that has generated specific research interest in comparative oral bioavailability and hepatotoxicity studies across modified DHT derivatives.
The 2 alpha methyl modification at the second carbon position is the structural feature that most distinguishes Methasterone from other DHT derived oral anabolic compounds in research. This modification significantly increases anabolic potency relative to the base DHT structure while the 17 alpha methyl group provides oral bioavailability, the combination producing one of the highest anabolic activity profiles among oral DHT derivatives documented in the research literature. Despite its relatively recent emergence as a research compound compared to mid 20th century anabolics, Methasterone has accumulated a growing body of literature examining its receptor binding characteristics and metabolic pathway given its unique dimethyl modification structure.

Superdrol (Methasterone) is a 17-alpha alkylated DHT derivative with an exceptionally high anabolic to androgenic ratio of approximately 400:20 compared to testosterone's 100:100; one of the highest anabolic selectivity ratios of any oral compound in the research catalogue. Originally synthesized by Syntex in the 1950s but never approved for pharmaceutical use, Superdrol was briefly marketed as a prohormone supplement before being banned. It is studied for rapid lean mass accretion, dramatic strength enhancement, and significant muscle fullness without aromatization to estrogen or water retention. Producing Anadrol comparable mass gains with far lower androgenic activity and no estrogen elevation. It is considered one of the most hepatotoxic oral anabolic compounds available.
15mg per day is the most commonly researched starting dose for Methasterone; balancing meaningful anabolic effects with a more manageable hepatotoxic burden than higher doses. Research demonstrates significant lean mass and strength increases at 10–20mg daily, with diminishing returns and substantially increased liver stress at doses above 20mg. The 15mg tablet allows once daily administration at the standard research dose, or split morning and evening dosing at 7.5mg each for more stable plasma levels. Some research protocols escalate from 15mg to 30mg (two tablets) in the second week after assessing initial liver enzyme response.
Methasterone is considered one of the most hepatotoxic oral anabolic compounds in the research catalogue. Producing significant ALT and AST elevation even at conservative doses and short cycle durations. Research protocols with Superdrol are typically strictly limited to 3–4 weeks maximum duration. Liver enzyme monitoring before, midway through, and after the research protocol is essential. Liver support with TUDCA at 500–1000mg daily and NAC at 1200mg daily is strongly recommended for the entire duration of any Superdrol research protocol. Alcohol consumption should be completely avoided. Any significant liver enzyme elevation should prompt immediate protocol discontinuation.
Yes! This F-40 Biotech batch has been independently HPLC tested by an accredited third party laboratory confirming concentration accuracy at 15mg per tablet and compound identity as Methasterone. A certificate of analysis is available.
