When should I stop using peptides and see a doctor immediately?

Seek immediate medical attention for: chest pain, severe abdominal pain, vision changes, signs of pancreatitis (persistent nausea/vomiting), sudden severe headache, or symptoms of blood clots (leg swelling, shortness of breath). Don't wait to see if symptoms resolve. <a href='https://www.cdc.gov/heartdisease/signs_symptoms.htm' target='_blank'>CDC Heart Attack Warning Signs</a>
