A side-by-side research comparison of Nandrolone Decanoate and Stanozolol across mechanism, dosing, half-life, benefits, side effects and research status.

Comparison table

AttributeNandrolone DecanoateStanozolol
Full nameNandrolone Decanoate (Deca-Durabolin)Stanozolol (Winstrol)
CategoryAnabolic SteroidsAnabolic Steroids
StatusPrescription drug (controlled substance)FDA-approved drug (controlled substance)
MechanismNandrolone is testosterone lacking the 19-carbon methyl group, giving it high anabolic and lower androgenic activity. It binds androgen receptors and, unlike testosterone, converts to a weaker androgen (rather than DHT) in some tissues, reducing certain androgenic effects but not estrogen-related ones.Stanozolol is a 17-alpha-alkylated DHT derivative that is orally active and resists aromatization. It has a relatively high anabolic-to-androgenic ratio and lowers sex-hormone-binding globulin (SHBG), increasing free hormone levels.
