BPC-157 + TB-500 Stack vs Larazotide
A neutral, side-by-side comparison of two healing & recovery peptides — their mechanisms, dosing ranges, administration routes, side effects, and research evidence. For research and educational purposes only.
BPC-157 + TB-500 Stack
The most widely researched peptide stack for tissue repair, combining BPC-157 (angiogenesis and growth factor upregulation) with TB-500 (actin regulation and cell migration). The two compounds address complementary and non-overlapping stages of the healing cascade, producing synergistic effects in tendon, ligament, muscle, and gut injury research models.
Full profileLarazotide
Larazotide (AT-1001) is a synthetic octapeptide that acts as a tight junction regulator — it competitively blocks zonulin, the primary physiological driver of intestinal permeability ('leaky gut'). It is one of the few compounds studied in human clinical trials specifically for tight junction dysfunction, with Phase 2 data in celiac disease demonstrating reduced intestinal permeability and symptom improvement even in the presence of ongoing gluten exposure.

How each works
BPC-157 + TB-500 Stack
BPC-157 and TB-500 work through entirely non-overlapping mechanisms and have been combined in numerous community protocols for injury recovery. BPC-157 drives angiogenesis and growth factor receptor expression; TB-500 regulates actin polymerization and cell migration into the injury site. No documented negative interactions exist — the combination is considered synergistic in the healing research community based on the complementary biology of each compound.
Larazotide
Zonulin upregulation disrupts the tight junction proteins occludin and claudin, allowing paracellular passage of antigens, LPS, and inflammatory triggers into systemic circulation. Larazotide acts as a tight junction agonist by competitively displacing zonulin from its receptor and directly stabilizing tight junction complexes. The Phase 2b CeD trial (N=342) showed larazotide reduced the ratio of lactulose/mannitol (L/M ratio, standard intestinal permeability marker) and improved GI symptom scores versus placebo in actively-challenged celiac patients.
