There is NO endorsed bodybuilding dose — this entry does not provide a protocol, because using insulin without diabetes can cause fatal hypoglycemia and there is no evidence it builds muscle in healthy people. For medical context only: insulin is a prescription drug dosed by a clinician for diabetes, individually titrated to blood glucose and measured in international units (IU). Any non-medical, performance-driven use is illicit and dangerous, and we deliberately give no dose, timing, or 'carb-with-insulin' scheme.

None for performance use — insulin is a prescription hormone for diabetes, not a muscle-building agent, and using it without diabetes risks fatal hypoglycemia

• Any non-medical / performance use by a non-diabetic — injecting insulin without diabetes can cause fatal hypoglycemia and is not a supplement use
• Use without a prescription or without medical supervision
• Existing hypoglycemia or hypoglycemia unawareness

• Growth hormone / IGF-1
• Alcohol
• Anabolic-androgenic steroids / other doping agents
