Research Overview
EGF
Human and animal studies show EGF can accelerate epithelial migration and wound closure, especially in burns, ulcers, and mucosal injury. Its best evidence is for topical or local delivery because systemic exposure is brief and the effect is highly localized.
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.
