Teduglutide vs GHRP-6

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

Recovery & Repair
Teduglutide
Growth Hormone Peptides
GHRP-6
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.
GHRP-6 is the original synthetic GH-releasing peptide and a potent ghrelin receptor agonist. It produces strong GH pulses but is notorious for a significant hunger surge 30–45 minutes post-injection. This hunger side effect makes it less preferred than Ipamorelin or GHRP-2 for most protocols but can be useful in patients with appetite deficiency.
