Short answer: Seek urgent care for chest pain, shortness of breath, fainting, severe dizziness, signs of stroke, or a painful or prolonged erection — do not use a supplement to delay medical care.
Why this warning is stated with unusual, direct urgency
Naming five specific, serious symptoms directly — rather than a vague "seek medical attention if needed" — reflects a genuinely important safety standard.
Why "do not use a supplement to delay medical care" is the critical instruction
This directly addresses a genuine risk: someone experiencing a serious symptom mistakenly waiting to see if a supplement helps instead of seeking immediate care.
⚠️ Worth knowing: any of these five symptoms warrant urgent medical attention immediately, not a wait-and-see approach with a supplement.
