Bradykinin Dosage Calculator

Bradykinin isn't something you reconstitute at home with an insulin syringe. This peptide belongs in a monitored research facility with continuous blood pressure tracking and emergency airway equipment on standby. Reconstitution math for reference: a 1 mg vial with 2 mL bacteriostatic water gives 500 mcg/mL. On a 100-unit insulin syringe, each unit equals 5 mcg. A 25 mcg dose would be 5 units; 100 mcg would be 20 units. Those numbers are mostly academic, though. Research protocols use calibrated infusion pumps delivering 10 to 100 nmol/min intra-arterially, not bolus injections. The half-life situation makes bradykinin unique among peptides. At 15 to 30 seconds, you can't maintain plasma levels with intermittent dosing. Continuous infusion is the only route to sustained pharmacological effect. Subcutaneous bioavailability sits below 5% because tissue kininases destroy the peptide before it reaches systemic circulation. Source from Bachem or Sigma-Aldrich only. Grey-market peptide vendors don't have the analytical standards needed for a compound going into arteries. Verify endotoxin content below 1 EU/mg before any in vivo work.
