Research Overview

Ac-SDKP

Ac-SDKP has literature in tissue remodeling, angiogenesis, and organ repair models. Its strongest evidence is pre-clinical, where it modulates inflammation and fibrosis during healing.

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.
