Frequently asked questions

What are peptides?

Peptides are short chains of amino acids, the building blocks of proteins. Some occur naturally in the body, and some are designed in a lab.

What does "research use only" mean?

It is a label used for compounds sold for laboratory work rather than as medicines. These products are not evaluated by regulators for safety or effectiveness in people.

Does this site sell peptides or give medical advice?

No. This is an educational reference. It does not recommend human use, dosing or sourcing, and it is not a substitute for advice from a qualified clinician.

How should I read the research summaries?

Look at the evidence level on each page. Findings from cell and animal studies often do not carry over to people, and many peptides have little or no human trial data.
