The peptide evidence authority

We publish our evidence — graded, scoped, and signed.

Fair Witness grades every peptide claim by research strength and adds what a four-decade clinician has observed in practice — in a voice built to help you decide, including not to.

How we grade every claim

We don’t ask you to trust a polished surface. We show the grade as the surface — the strength of the evidence, the human-vs-animal split, and the regulatory status, on every peptide:

Strength of evidence

Human vs animal data

Regulatory status

Research-only · not FDA-approved

Illustrative grade. Every published peptide carries its own evidence apparatus, cited to the underlying studies and cleared by our Medical Director.

The launch library

We go narrow and deep first — a focused set of compounds, each a graded, cited, clinician-reviewed explainer:

  • GHK-Cu
  • BPC-157
  • Ipamorelin
  • CJC-1295

Latest

  • BPC-157 — A graded, cited synthesis of the BPC-157 evidence — human vs animal data quantified, FDA status surfaced, clinician-reviewed.

We sell nothing. We run no storefront. We carry no affiliate links. The most resonant promise we make is the one most publishers won’t: when the honest read of the evidence is “not yet” — we’ll tell you that too.
