Search the exact term first

Start with the peptide name plus a neutral topic such as mechanism, clinical trial, pharmacology, or review.

Sort by evidence type

Separate reviews, animal studies, in vitro work, clinical trials, and case reports. They do not carry the same weight.

Check dates and context

Older papers can be useful for mechanism history, but they may not reflect current clinical, regulatory, or analytical standards.

Avoid conclusion stretching

A PubMed result does not automatically validate marketing claims, supplier pages, safety claims, or human-use instructions.
