What are peptides?
Peptides are short chains of amino acids joined by peptide bonds. Some occur naturally in the body; others are made for research or as medicines. Different sequences have different properties, so the word peptide alone does not tell you what a substance does. [1]
Are all compounds in a peptide library actually peptides?
No. NAD+ is a coenzyme, and 5-Amino-1MQ is a small molecule. They appear in this library because of related research topics, rather than because they have the same chemistry.
How should I compare the evidence?
Start with the actual substance, then check the study type. A result from isolated cells or animals does not establish a treatment benefit in people. Human studies also differ in their size, design, participants and measured outcomes.
