Gonadorelin
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.
Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
Half-Life
~2 hours; once-daily dosing due to gut-specific residence
~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization

Key Benefits
  • Increases intestinal villus height and absorption surface area
  • Reduces intestinal permeability (leaky gut)
  • FDA-approved for short bowel syndrome
  • Reduces parenteral nutrition dependence in SBS patients
  • Promotes intestinal mucosal healing in IBD
  • Increases tight junction proteins ZO-1 and occludin
  • Maintains testicular size during TRT
