Insulin (non-diabetic use)
Insulin / Humalog / Lantus / slin · Hormone (misused as anabolic adjunct)
What it is
Pharmaceutical insulin, misused in bodybuilding by people without diabetes. No controlled evidence supports any safe or effective use in that context.
What human evidence shows
Insulin's anabolic signaling is real physiology; that is where the legitimate evidence ends. There are no trials of non-diabetic physique use and never will be — the dose-error consequence forecloses the study design.
Risks
Severe hypoglycemia can rapidly cause seizures, brain injury, or death — bodybuilding's documented insulin fatalities are exactly this failure. This is among the most acutely dangerous practices covered anywhere in this catalog. Insulin is WADA-prohibited in sport without an applicable medical exemption.
Legal status
US: a prescription pharmaceutical in its common formulations. Legality of a product is not safety of a practice; this entry exists because the names circulate, not to normalize the use.
Evidence base
Not auto-graded. This entry covers several different drugs, or a use the published research was never about, so no single letter honestly describes it. The reading below is real literature — read it against what this page says, not as a score.
