The most advanced peptide for gut permeability, in Phase III trials for celiac disease. Works locally in the GI tract to tighten intestinal junctions and reduce gluten-induced inflammation.

A pentadecapeptide derived from human gastric juice, widely studied for its remarkable tissue-healing properties across tendons, ligaments, muscles, and the GI tract.

A synthetic fraction of Thymosin Beta-4, a naturally occurring peptide found in high concentrations at wound sites. Known for its systemic healing and anti-inflammatory properties.

A naturally occurring copper peptide found in human plasma that declines with age. One of the most versatile peptides with evidence for skin, hair, wound healing, and anti-aging applications.

The full-length version of what TB-500 is derived from. Present in all cells and tissues, with highest concentrations at wound sites. More comprehensive than TB-500 but less commonly available.

A powerful anti-inflammatory tripeptide derived from alpha-MSH. Studied for inflammatory bowel disease, skin conditions, and systemic inflammation without the tanning side effects of full alpha-MSH.

An arginine-rich peptide studied for wound healing and tissue repair, with emerging data on GI tract protection similar to BPC-157.
