What is Dbol?
Methandrostenolone (Dianabol, Dbol) is a 17α-methylated, C1-2 dehydrogenated testosterone derivative — the archetypal oral anabolic steroid. Moderate AR affinity, low SHBG binding, and modest aromatisation to methylestradiol. Research use only.
Research Applications
AR Pharmacology
Moderate AR agonism, anabolic gene program — protein synthesis, nitrogen retention
Aromatisation Research
Methandrostenolone-to-methylestradiol conversion, aromatase substrate kinetics
Oral AAS Bioavailability
17α-methyl first-pass hepatic resistance, enterohepatic cycling, oral PK
Historical AAS Reference
First widely studied oral AAS — benchmark compound for comparative AAS pharmacology
HPG Axis Impact
LH/FSH suppression at anabolic doses, testosterone feedback, hypothalamic ER interaction
