What Judaism Teaches About Steroids for Muscle Gain
Judaism's ruling is anchored in the self-injury principle the Talmud states plainly: one who wounds himself, though the court cannot punish him, violates a prohibition (chovel b'atzmo, Bava Kamma 91b) — and poskim apply it to any knowing, non-therapeutic damage to healthy organs and systems. Steroid harms land squarely: the cardiac literature, endocrine suppression, and psychological effects are the wound, slow-motion. The body-guard duty (Deuteronomy 4:9; Maimonides' De'ot 4 opening) frames the positive: the body is service infrastructure, and maintenance is religious. Doping in sport adds the civil-law layer — banned substances violate dina d'malkhuta dina (Nedarim 28a) — plus the geneivat da'at dimension: competitors and organizers are misled about what they are witnessing. The therapeutic exception is halakhically clean: prescribed hormone treatment for deficiency is refu'ah, and Jewish law not only permits but prioritizes healing ('and he shall surely heal,' Exodus 21:19). Contemporary rabbis writing for the gym generation add the wisdom note: the Mussar teachers warned about ga'avah (pride) clothing itself in any achievement — and a physique that requires deception and damage is a costly garment.
