Plain-English primer
What are peptides?
Peptides can feel confusing fast. This section gives you the short version first so you can understand the category, see why people look into it, and know how to use this site without getting lost.
What they are
Peptides are short chains of amino acids. Some are studied because they may influence things like appetite, recovery, sleep, inflammation, or hormone signaling.
Why people research them
Most people arrive here trying to sort through confusing claims, compare options, and understand where a peptide might fit before they go deeper.
