WILGO RESEARCH INDEX

Peptide Evidence Matrix

A side-by-side map of the evidence types located for the ten launch compounds. The matrix deliberately avoids a made-up numerical score and links readers back to the underlying studies.

COMPARATIVE MAP

Evidence by compound.

This is a navigation aid, not a numeric score. A check in a category means relevant literature was located; it does not mean the evidence is large, positive, replicated, or clinically sufficient.

How to read the matrix

Randomization, human participation, animal evidence and cell evidence answer different questions. Follow each compound link for study design, endpoints, limitations and primary sources. “None located” means none identified in the literature set reviewed for this index—not proof that no study exists anywhere.

*TB-500 / Tβ4: Most peer-reviewed evidence is for native thymosin beta-4. Commercial use of the name “TB-500” does not establish identity with the material used in those studies.
