Histatin-5 Side Effects
- ⚠local irritation
- ⚠proteolytic instability
- ⚠dose-dependent cytotoxicity in vitro
GHRP-6 Side Effects

Research Overview
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
GHRP-6
GHRP-6 has solid pre-clinical and clinical evidence for GH stimulation. Well-characterized pharmacology. More appetite stimulation than Ipamorelin due to ghrelin receptor activation.
