Teduglutide vs HGH Fragment 176-191

Side-by-side comparison of key properties, dosing, and research.

Teduglutide
Fat Loss & Metabolic
HGH Fragment 176-191
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.
HGH Fragment 176-191 (also known as AOD-9604) is a stabilized, modified fragment of the human growth hormone molecule corresponding to amino acids 176–191 with an addition of a tyrosine residue at the N-terminus. It retains HGH's fat-burning properties without the anabolic, diabetogenic, or IGF-1-stimulating effects.
