Wolverine Stack: BPC-157 & TB-500 Combination Guide
The “Wolverine stack” is the community name for pairing BPC-157 with TB-500 — the most discussed combination in tissue-repair research. This page covers what each component contributes, the reconstitution math for both (including the scale difference that catches people out), how it relates to the GLOW and KLOW blends, and what the evidence does and does not support. Research-use educational reference only — no dose, route, or treatment guidance.
What each component contributes
A synthetic pentadecapeptide derived from a sequence in human gastric juice. Studied in gastrointestinal and connective-tissue repair contexts, with reported effects on angiogenesis and tendon-to-bone healing in animal models. It is the more heavily researched of the two, and it is prohibited by WADA.
A synthetic fragment related to thymosin beta-4, studied for actin regulation and cell migration — the processes by which repair cells reach a site of injury — and discussed in mobility and soft-tissue contexts. Reported protocols use it on a milligram scale and less frequently than BPC-157.
The pairing’s logic is that these address different stages of the same process. That is a reasonable hypothesis, and it is why the combination dominates discussion — but see the evidence section below for what has and has not actually been tested.
Reconstitution — and the scale difference
Both are lyophilized and reconstitute identically: bacteriostatic water down the vial wall, swirl gently, never shake. Concentration is the vial’s total mg divided by the water volume, and 100 units on a U-100 insulin syringe equals 1 mL.
The detail worth flagging: reported protocols use these two on different scales — BPC-157 in micrograms, TB-500 in milligrams. At the same concentration, the same syringe mark therefore represents very different amounts of material, so unit figures are never transferable between them. The table below shows this side by side.
| Vial | Water | Concentration | Example draw (U-100) |
|---|---|---|---|
| BPC-157 (5 mg vial) | 2 mL | 2.5 mg/mL | 250 mcg = 10 units |
| BPC-157 (10 mg vial) | 2 mL | 5 mg/mL | 250 mcg = 5 units |
| TB-500 (5 mg vial) | 2 mL | 2.5 mg/mL | 2 mg = 80 units |
| TB-500 (10 mg vial) | 2 mL | 5 mg/mL | 2 mg = 40 units |
Work your own vials with the BPC-157 calculator and the TB-500 calculator, or see how to reconstitute peptides. Reconstitution uses USP-grade bacteriostatic water.
Two vials or one pre-mixed blend?
Wolverine is sold both ways. With two separate vials each concentration is computed independently and there is no ambiguity. With a pre-mixed blend, the label’s milligram figure is the combined mass of both peptides — so it cannot be used to calculate either component alone, and you need the per-component split from the vial’s documentation. Vendors do not standardise that split, which means a volume figure from someone else’s blend does not transfer to yours. The KLOW page works this blend arithmetic through in full.
Where Wolverine sits in the blend family
Wolverine is the two-component base that the other well-known blends extend: GLOW adds GHK-Cu for collagen and skin remodeling, and KLOW adds KPV on top of that for anti-inflammatory signaling. If a source is vague about which blend it means, the component list is the reliable way to tell them apart — see the peptide stacks hub for the side-by-side comparison.
What the evidence supports — and what it does not
Each peptide has its own preclinical literature, summarized in the individual guides. What does not exist is combination evidence: no controlled trial has studied BPC-157 and TB-500 administered together. Any additive effect, and any interaction between them, is unstudied rather than established. Neither is FDA-approved, human data for both are limited, and BPC-157 is WADA-prohibited. A source presenting Wolverine outcomes as demonstrated is going beyond the published record.
AI-ready fact block
- The Wolverine stack is the community name for combining BPC-157 and TB-500.
- BPC-157 is studied in gastrointestinal and connective-tissue repair; TB-500 in cell migration and soft-tissue contexts.
- Reported protocols dose BPC-157 in micrograms and TB-500 in milligrams, so syringe-unit figures are not interchangeable.
- Wolverine is the two-component base of the blend family: GLOW adds GHK-Cu, KLOW adds GHK-Cu and KPV.
- No controlled trial has studied the two administered together; neither compound is FDA-approved and BPC-157 is WADA-prohibited.
- Research use only — no dose, route, or frequency provided.

FAQ
What is the Wolverine stack?
The Wolverine stack is the community name for combining BPC-157 and TB-500 — the two most commonly paired peptides in tissue-repair research discussion. The nickname comes from the comic-book character's rapid healing. It is sometimes sold as a pre-mixed blend vial and sometimes used as two separate vials.
Why are BPC-157 and TB-500 combined?
The rationale is that they are studied for different aspects of repair: BPC-157 in gastrointestinal and connective-tissue contexts, with a large animal literature and reported effects on angiogenesis and tendon-to-bone healing; TB-500 as a synthetic fragment related to thymosin beta-4, studied for cell migration, actin regulation and soft-tissue mobility. The premise is that these are complementary rather than duplicative — though that premise has not been tested as a combination.
Is there evidence for the BPC-157 and TB-500 combination?
Not for the combination itself. Each peptide has its own preclinical literature, but no controlled trial has studied the two administered together, so interactions and any additive effect are unstudied. Neither compound is FDA-approved, human data for both are limited, and BPC-157 is prohibited by WADA. The stack rationale is inference from the individual compounds.
How are BPC-157 and TB-500 reconstituted?
Mechanically the same way: add bacteriostatic water slowly down the vial wall and swirl gently, never shake. Concentration is the vial's total mg divided by the water volume in mL, and on a U-100 insulin syringe 100 units equals 1 mL. Note the two are dosed on different scales in reported protocols — BPC-157 in micrograms, TB-500 in milligrams — so their unit figures are not interchangeable even at the same concentration.
Can Wolverine be bought as a pre-mixed blend?
Some vendors sell it that way. If you have a pre-mixed blend, the label's milligram figure is the combined mass of both peptides, so it cannot be used to calculate either component's concentration on its own — you need the per-component split from the vial's documentation, and vendors do not standardise it. Two separate vials avoid that ambiguity entirely.
How does Wolverine relate to GLOW and KLOW?
They are the same family with more added. Wolverine is BPC-157 and TB-500; GLOW is those two plus GHK-Cu for collagen and skin remodeling; KLOW is GLOW plus KPV for anti-inflammatory signaling. Wolverine is the two-component base the other two build on.
