Research Overview
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.
Teriparatide
Teriparatide has extensive clinical literature showing anabolic effects on bone and investigational use in delayed unions and nonunions. It is one of the best-studied peptide-based options for skeletal recovery.
