Oxandrolone vs Oxymetholone
updated
Oxandrolone (tier S) vs Oxymetholone (tier S): what each is, why each got its grade, half-life and source counts side by side.
Oxandrolone · tier S
Anavar is oral oxandrolone, an anabolic-androgenic steroid used in bodybuilding for muscle, strength, and a leaner or harder look.
tier rationale
S grades the certainty of the identity, human PK, and randomized outcome record; it is not a safety or current-approval grade.
Oxymetholone · tier S
an oral 17-alpha-alkylated anemia drug with legal FDA approval but no active US marketing, controlled human lean-mass data, severe dose-related hepatic toxicity, and animal-only terminal half-life.
tier rationale
S tier reflects clear identity, an FDA-reviewed label, and multiple controlled human outcome datasets. Severe hepatic and lipid toxicity, discontinued marketing, and missing human terminal PK are stated as central facts, not hidden by the grade.
