Key differences
Both BPC-157 and TB-500 sit at the same evidence tier (Tier 3), so neither has a clear edge in how strong its human data is. Neither is FDA approved for human use — both are not fda approved / not fda approved and treated as research compounds in the US.
BPC-157 has 0 human trials on record (0 subjects) versus TB-500's 0 (0 subjects). Evidence tiers are a shorthand for how strong that human data is — see our guide to understanding peptide evidence tiers for how to weigh them.
What is BPC-157?
BPC-157 is a synthetic pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. Preclinical research suggests it promotes angiogenesis and tissue repair. As of 2026 it has not been studied in published human randomized controlled trials and is not FDA-approved; the evidence… Full BPC-157 breakdown →
What is TB-500?
TB-500 is a synthetic peptide corresponding to the active region of Thymosin Beta-4, a naturally occurring protein involved in actin regulation and cell migration. Animal studies investigate roles in wound healing and tissue repair. It is not FDA-approved and lacks published human randomized controlled trials. It is… Full TB-500 breakdown →
Where to buy BPC-157 or TB-500 safely
Both are sold by research-chemical suppliers, not pharmacies, so the source matters as much as the compound. Before buying either, vet sellers on third-party lab testing and enforcement history in the ranked directory of trusted peptide sellers — or jump straight to vetted sources for BPC-157 or TB-500. PeptidesHub does not sell either compound.
