BPC-157 vs TB-500 — evidence grades compared.
The honest verdict
BPC-157 and TB-500 sit at the same evidence tier — both Grade D (animal studies only, unproven in humans).
A tie at the bottom: both are Grade D (animal data only) and both are under FDA review for the July 2026 PCAC vote. Neither is proven in humans, so "which is better" is the wrong question — the honest answer is that the wolverine stack's recovery claims outrun the evidence for either one.
