Is Human CCK-8 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Human CCK-8? Is Human CCK-8 safe for nursing mother and child? Does Human CCK-8 extracts into breast milk? Does Human CCK-8 has any long term or short term side effects on infants? Can Human CCK-8 influence milk supply or can Human CCK-8 decrease milk supply in lactating mothers?

Human CCK-8 is a synthetic octapeptide analogue of cholecystokinin. Because Human CCK-8 has a molecular weight of 1143, the amount in milk is likely to be very low and oral absorption by the infant is unlikely because it is probably destroyed in the infant's gastrointestinal tract. The serum half-life of Human CCK-8 is less than 2 minutes, indicating that withholding breastfeeding for 10 minutes after a dose should ensure that the infant is not exposed to the drug.
