How it works
1
Endotoxin value (from CoA)
The endotoxin result stated on your Certificate of Analysis. Toggle EU/vial or EU/mg to match how your CoA reports it.
2
Peptide vial quantity
The peptide mass in the vial, in milligrams. Used to convert the CoA figure into endotoxin per milligram of peptide.
3
Your peptide per dose
The amount of peptide in a single research dose, in milligrams. This sets the endotoxin delivered per dose.
4
Absorption window
The time the dose is taken up over, from 1 to 24 hours. Spreading it over longer lowers the effective EU/kg/h load.
5
Body weight
The research subject’s body weight, in kg or lbs. The endotoxin limit scales with body weight, so the verdict updates instantly.
Based on the compendial parenteral endotoxin limit K = 5.0 EU/kg per hour. Reference tool only; always confirm against the product Certificate of Analysis.
