Restorative Peptides

Peptide bibliography

These papers approach repair at different scales, from an actin attachment to an injured rat tendon. Their subjects and test substances matter as much as their conclusions.

Thymosin beta-4 and scar formation

The 2012 review is the starting point for the scar question on this site. The actin structural paper concerns a molecular attachment; the stroke experiment concerns neurological recovery in rats. The healthy-volunteer trial examines short-term tolerability of the full protein. Each leaves the TB-500 fragment with questions of its own.

BPC-157 tissue studies and human reports

The rat ulcer study describes rebuilding of the stomach lining. The rat Achilles study examines tendon repair. The vascular experiments investigate a proposed pathway, while the rat-and-dog study follows the substance's handling in the body.

The small human pilot and the reviews appear in the full list below.
