hBD-1 Side Effects

  • protease degradation
  • local irritation at high dose
  • limited stability in saliva

IGF-1 LR3 Side Effects

  • Common: Hypoglycemia (dose-dependent), joint pain, water retention
  • Moderate: Gut growth concern (high doses), acromegaly-like symptoms
  • Serious: Theoretical cancer risk (prolonged high-dose use)

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.
