Research Overview

OGP

OGP has mostly preclinical literature showing effects on bone cell signaling, mineralization, and repair models. It is not as clinically established as teriparatide or BMPs, but it is a genuine peptide in the bone-regeneration literature.

P-15

P-15 is a real literature-backed peptide used to improve biomaterial performance in bone repair settings. Most of the evidence is device- or scaffold-based rather than as a free systemic peptide.
