Recovery & Healing
These compounds are most often discussed in the context of tissue repair and recovery. The published research skews heavily toward animal and in-vitro models — human evidence is limited, and that gap is noted on every page.
BPC-157
AnimalA synthetic 15–amino-acid peptide derived from a protein found in gastric juice, studied predominantly in animal models for soft-tissue and gastrointestinal healing.
KPV
AnimalA three-amino-acid fragment of α-MSH studied for anti-inflammatory activity, particularly in the gut, largely in preclinical models.
Larazotide
HumanAn orally-acting peptide that regulates intestinal tight junctions, studied primarily as an adjunct in celiac disease.
Pentadeca Arginate (PDA)
AnecdotalA newer compound structurally related to BPC-157, marketed heavily for tissue recovery — but with a notably thin published evidence base.
TB-500
AnimalA synthetic peptide based on an active region of thymosin beta-4, a naturally occurring protein involved in cell migration and tissue repair.
VIP (Vasoactive Intestinal Peptide)
MixedA naturally occurring signaling neuropeptide with broad roles in immune and inflammatory regulation, discussed in chronic-inflammation and gut contexts.
