Research Overview
hBD-1
hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
IGF-1 LR3
IGF-1 LR3 has extensive in vitro and animal data. Its role in muscle hyperplasia is well-documented. The extended half-life modification provides practical advantages over native IGF-1.
