Cosyntropin
FDA-approved ACTH (the pituitary signal that tells the adrenals to make cortisol) stim test agent (Cortrosyn).
What it's for
FDA-approved ACTH (the pituitary signal that tells the adrenals to make cortisol) stim test agent (Cortrosyn).
What it's for
Cosyntropin is a lab-made peptide corresponding to the first 24 amino acids of ACTH (the pituitary signal that tells the adrenals to make cortisol). It is used diagnostically in ACTH (the pituitary signal that tells the adrenals to make cortisol) stimulation testing to evaluate adrenal cortisol production.
What it does for the body
It is used diagnostically in ACTH (the pituitary signal that tells the adrenals to make cortisol) stimulation testing to evaluate adrenal cortisol production. People often hear about it through clinics, forums, or news — this guide sticks to what published research and regulators actually support.
What it targets
MC2R activation in adrenal cortex acutely increases cortisol, which is measured in stim tests. Researchers map these ideas in cells and animals first; human proof has to clear a higher bar.
Research context
Bottom line for readers: Cosyntropin has a defined FDA-approved story. Use the citations tab to open labels and trial registries, and treat anything beyond the label as unverified.
