Wolverine Stack explained: BPC-157 + TB-500 together

Search any research-peptide forum for recovery work and one phrase keeps coming up: the "Wolverine Stack". It isn't a compound. It's a pairing — BPC-157 and TB-500 run side by side — that has become so standard in the tissue-repair literature it earned its own nickname. Here's what the stack actually is, why the two are paired, and what you receive when you buy one, in plain English.

What the Wolverine Stack actually is

Two separately studied research peptides, supplied together:

• BPC-157 (10 mg) — "Body Protection Compound 157", a synthetic pentadecapeptide derived from a protein found in gastric juice. Studied in gut-lining, tendon-healing and tissue-repair research.
• TB-500 (10 mg) — a synthetic fragment of Thymosin Beta-4, a naturally occurring protein involved in cell repair and movement. Studied in cell-migration, angiogenesis and muscle-recovery research.

The key thing to understand — and where a lot of buyers get confused — is that the Wolverine Stack is not a single mixed vial. You receive a labelled BPC-157 vial and a labelled TB-500 vial, each with its own batch number and Certificate of Analysis, and each reconstituted on its own. Blends that put several compounds into one vial, like KLOW, are a different product type with different trade-offs.

Why researchers pair them

The pairing is popular because the two compounds sit in overlapping but different parts of the recovery literature. BPC-157 is most associated with local tissue-repair models — tendon, ligament and gut-lining work. TB-500's Thymosin Beta-4 origin puts it in the cell-migration and angiogenesis strand: the mechanics of how cells move into damaged tissue and how new blood vessels form around it. A researcher studying recovery and repair therefore gets two complementary angles rather than two versions of the same one. Our full comparison, BPC-157 vs TB-500, goes deeper on what separates them.

A note on the name: "Wolverine" is community shorthand from the recovery-research context, nothing more. It is not a claim about what the compounds do in a person, and nothing in this article should be read that way.

Stack or single vials — which to buy?

Practically, buying the stack is just buying the two vials together. The advantages are small but real: you get the pair in one order at a slightly lower price ($199 versus $204.98 for the two bought separately), and you know both are from tested, documented batches. The only reason to buy singles instead is if you need a different quantity of one than the other — the stack is strictly one-and-one.

Handling and storage

Both vials arrive as lyophilised (freeze-dried) powder. Store at −20°C, reconstitute each vial separately with bacteriostatic water, then refrigerate and keep out of light. Because they are two vials, you'll work out two concentrations — the reconstitution calculator handles that, and our guide to storing and reconstituting peptides covers the rest.

Sourcing the Wolverine Stack in Australia

We hold both vials in Australian stock, independently batch-tested with each Certificate of Analysis published, dispatched same or next business day from Melbourne. Before you order, you can read the actual lab result for each batch in our CoA Library — with a two-vial stack, checking both CoAs matters. For the full research breakdown, see the Wolverine Stack research page.
