Is buying Iron online safe?
Vendor safety varies. BodyHackGuide scores every vendor on a 0-100 Trust Score (COA verification, payment transparency, community feedback, shipping practices). This page ranks listings by price per mg, not by score, so check each vendor's score breakdown on its BodyHackGuide profile before you buy.
Do I need a prescription for Iron?
Iron is sold for research-use-only by the vendors on this page; no prescription required for research purchases. None of these vendors sell Iron for human consumption, and BodyHackGuide doesn't promote off-label use. Always consult a licensed practitioner before any compound enters a clinical context.
