PepsRESEARCH FIELD GUIDE
BPC-157 vs TB-500: compare the research, not the reputation
Tendon models, fragment identity, and a tiny eye-drop trial answer different questions. Here is how to keep them separate.

THE PEPTIDE RESEARCH ATLAS
Peptide research, explained.
Find the evidence.
Plain-language summaries of the published research on 109 peptides and popular supplements: what was studied, what it found and what is still unknown. Every claim links to its source, and nothing here is dosing advice.

MOTS-c and exercise: what happened in people, and what happened in mice
One paper can contain several kinds of evidence. An exercise-associated signal is different from a human treatment result.

VENDOR CATALOG
Research sellers, side by side.
Research compounds, blends, bioregulators and vial bundles from several research sellers, with dated prices.
A dated price snapshot, not a live feed. Prices exclude shipping and tax; ranges cover product options. Confirm the final price with the seller. These are related shops, not competing suppliers. Research products are labeled by the vendor for research use only, not human use. Supplement-site classifications reflect the seller’s categories, not a PepsRadar finding of safety, effectiveness, or approval. Vendor research policy (affiliate link).

STUDIES, NOTES & PODCASTS
Follow the research and the conversation.
Published studies first, then reviewed editor’s notes, then the video and podcast index. Automatic discoveries come last and are marked unreviewed.
FROM THE LITERATURE
Latest studies
Recent PubMed records, with direct links to the original citations.
Records may concern cells, animals, or people; inclusion does not establish clinical benefit. A title alone is not an evidence review.

Titles and speaker claims are not PepsRadar findings. Automatic captions can mishear compound names; timestamp matches need human review. This index is not a review of every video.
