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.

| One-line verdict | BPC-157 is not FDA-approved and is not yet legal to compound. On July 23, 2026 the FDA's PCAC panel voted 8 to 6 (1 abstention) to recommend adding it to the 503A list for ulcerative colitis, overriding the FDA's own scientists, but that is a recommendation only and the FDA has not decided. Human evidence stays Grade D: animal studies only. If you pursue it, wait for the FDA's ruling and use a licensed provider, never gray-market vials. | TB-500 is not FDA-approved and is not yet legal to compound.
