Most antibiotics, methotrexate, and pyrimethamine invalidate folic acid and vitamin B12 diagnostic microbiological blood assays
It depends entirely on how you store that powder, what amino acids comprise its sequence, and whether moisture has infiltrated the vial at any point during storage
Another peptide with promise: LL-37 is an antimicrobial peptide involved with our innate immune system of defense against microbial invasion and decreases gut permeability via improved tight junctions (claudin, occludins)
it slows gastric emptying and signals satiety to the brainstem and hypothalamus, reducing food intake
