The Basics shelf is the place to start if the word peptide still feels vague. These guides explain what a peptide is, how amino acids link into chains, and where peptides sit between single amino acids and full proteins. They also cover the questions people ask first, such as whether peptides are steroids and how NAD+ products differ from peptide therapy.
Read them in order and the rest of the site gets easier. Start with what peptides are and why they are in the news, then how amino acids build proteins, and finish with seven peptide myths that keep coming back. Unfamiliar terms are defined in the glossary.
