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.
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.
