A peptide is a chain of amino acids held together by peptide bonds, and those bonds are precisely what digestive enzymes (pepsin, trypsin) are built to cut, with the acidic stomach environment finishing the job so an oral peptide is largely destroyed before it can be absorbed, which is why injection is the default
Yes, injections work faster and absorb more efficiently especially for those with digestive issues or severe deficiency
NAD+ requires a different syringe and site because its acidity can degrade peptides on contact
