Off-label longevity use mirrors low antihypertensive dosing (captopril is short-acting; longer-acting ACE inhibitors like lisinopril/ramipril are often used) under a clinician. Not an approved longevity regimen; blood pressure and potassium should be monitored. (the cited human trial does not state its captopril dose)
