TeduglutideCognitive Enhancement
Dihexa- Summary
- Teduglutide is a GLP-2 (glucagon-like peptide-2) analog with enhanced stability. Unlike GLP-1, GLP-2 specifically acts on the intestinal epithelium to increase intestinal length, villus height, and absorption surface area. FDA-approved as Gattex for short bowel syndrome, it is also being investigated for IBD, leaky gut, and mucosal healing.
- Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.
