GLP-1 / Weight Loss Agonists
SemaglutideRecovery & Repair
Larazotide Acetate- Summary
- Semaglutide is an FDA-approved GLP-1 receptor agonist originally developed for type 2 diabetes that has proven remarkably effective for weight loss. Clinical trials show average 15–20% body weight reduction. It is marketed as Ozempic (diabetes) and Wegovy (weight management).
- Larazotide acetate is an 8-amino acid peptide (Gly-Gly-Val-Leu-Val-Gln-Pro-Gly) derived from Zonula Occludens Toxin (ZOT) of Vibrio cholerae. It paradoxically acts as a ZOT antagonist to close tight junctions and reduce intestinal permeability ('leaky gut'). It is the most advanced clinical compound targeting gut permeability directly.
