Peptides for Leaky Gut
Peptides for leaky gut has a surprisingly specific answer. Larazotide is the peptide built for the job. It reached Phase 3 trials. BPC-157 is the gut peptide people can actually order. You will need to create a free account with the vendor below to be able to order.

What Are the Best Peptides for Leaky Gut?
Leaky gut is shorthand for a gut wall that lets too much through. Tiny seals between gut cells control that, and larazotide was designed to tighten them. It carries real randomized celiac trial data. BPC-157 is the stomach protein fragment with hundreds of rodent gut studies. It is the one vendors actually stock.

Do These Peptides Work?
Larazotide improved celiac symptoms in a 2015 randomized trial. It then failed a Phase 3 check in 2022 and was shelved. That is the most complete evidence trail any gut peptide has. BPC-157’s gut data is deep, but all of it comes from animals. The table below is a brief summary of the research.

| Finding | Model |
|---|---|
| Larazotide improved celiac symptoms | Randomized controlled trial (2015) |
| Larazotide Phase 3 program | Stopped for futility (2022) |
| BPC-157 intestinal protection | Hundreds of rodent studies |
| Human leaky-gut trials of BPC-157 | None published |
What this evidence does not cover
A leaky gut wall can be measured, but leaky gut as a diagnosis is not medically recognized. No peptide is FDA approved for it. Larazotide’s Phase 3 failure is a warning against trusting early trials. Research vials are not supplements, and a batch-matched third-party COA is still the minimum standard.

What Does BPC-157 Cost?
BPC-157 runs $30 to $60 for a 5 to 10mg vial, or a few dollars per mg. Larazotide never reached the market and is hard to find even as a research compound.
Prices well below that range usually mean skipped testing or short-filled vials. Leaky-gut marketing draws more fakes than almost any niche.
